Definitions

  • the present invention relates to the field of construction and architecture and in particular to a decorative material with a colourdynamic surface and a method of obtaining thereof.
  • the invention may be used in the manufacture of various facing and ornamental materials, construction products and also of a wide variety of adticles whose appearance is of particular importance, such as domes for lighting fixtures, decorative crokery, elements of furniture, machines and equipment, decorative grates of different purposes, natural fabrics and nonvowen materials and, respectively, various kinds of clothes, footwear, leather donrdashery, plastic articles.
  • the invention allows the manufacturing of a aide range of finishing materials and construction products with a decorative colourdynamic surface, such as ceramic, gypsum, glass, polymeric and other facing tiles, facing bricks and ceramic blocks, ferroconcrete wall panels and partitions, cellular and lattice plates for suspended ceilings, glass blocks and ornamental strain-glass panels, polymeric and metal sheet materials, synthetic films and wallpaper, etc.
  • a decorative colourdynamic surface such as ceramic, gypsum, glass, polymeric and other facing tiles, facing bricks and ceramic blocks, ferroconcrete wall panels and partitions, cellular and lattice plates for suspended ceilings, glass blocks and ornamental strain-glass panels, polymeric and metal sheet materials, synthetic films and wallpaper, etc.
  • the invention allows imparting the decorative colourdynamic properties to practically any construction or funishing material used today.
  • the colourdynamic surfaces can change their colour both in narrow and wide colour ranges with the change of visual angle or angle of light incidence.
  • a colourdynamic tile if viewed at different angles, can successively look as red, orange, yellow, green, blue and violet each time acquiring a bright saturated spectral colour in compliance with the given position of the observer.
  • the present invention is based on the principles of formation of raster dynamic representations known long before.
  • a raster optical system is first of all a specially organized optical system whose elements can solve this or that optical problem operating only as a combination, Therefore, further in the text the raster materials or surfaces shall be referred to as the materials which produce optical decorative effects due to the combined action of the raster components.
  • the difference in shape between the facets of the adjacent bulging elements changes successively and in cycles along the preset line in such a manner that the play of light during relative displacement between the surface and the observer's eye travels successively along this line.
  • the decorative properties of such a material are based on the light reflection from the differently oriented (in different directions) three-dimensional elements complemented by the presence of dynamic moire effects, i.e, cyclic tone-light thickenings and thinnings appearing on the material and moving over it as the observer moves at the expense of cyclic changes of the differences in profile between the facets of the adjacent bulging elements.
  • the method is used in manufacturing the double-colour texture and relief ceramic plates.
  • the method consists in that after pressing the plates by means of a relief punch with the formation of the face texture or relief and application of a pigmented homogeneous glaze over the entire face, a glaze of the colour other than that of the glaze already applied, usually much darker, is deposited by spraying crosswise from one side. In so doing the spray cone should be directed at an acute angle to the main surface of the plate. As a result, the coloured coat of the texture or relief elements of the plate sides oriented to the spray cone is darker than that of its opposite sides which practically were not coated with the dark glaze.
  • the explanation consists in that, firstly, the texture and rel ef of the plates are actually developed rather insignificantly and from the majority of the real points of vision an observer can see both the dark and light sides of the texture elements simultaneously.
  • the degree of the texture development and that of the article relief may be characterized as a ration of the total surface area of the texture three-dimensional elements including the surface area of the spaces between the bases of these elements to the main surface area upon which said elements are located. This ratio may be also called a surface texture factor which varies in the range from 1.001 to 1.007 in said plates.
  • the texture elements of the plates have smooth rounded-off peaks which do not ensure a presice colour separation both in the crosswise spraying of the glaze and, respectively, in the visual colour perception of the surface.
  • Relative sharpness of the peaks of the texture elements may be determined as the ratio of the mean height of the elements to the mean rounding radius of their peaks.
  • the ration of the mean height of the texture elements to the mean rounding radius of their peaks varies in the range from 0.5 to 1.7.
  • the essence of the invention consists in that in a decorative material with a colourdynamic texture surface having three-dimensional elements of the texture or relief whose differently oriented sections are of different colour according to the invention, the texture surface is formed by the three-dimensional elements with the ratio of the total surface area of all the three-dimensional elements and that of the intervals between the bases of these elements to the area of the surface on which they are located lying in the range from 1.2 to 24 and with the ratio of the mean height of the three-dimensional elements to the mean rounding radius of their peaks being in the range from 3 to 300, while the differently oriented surface sections of each three-dimensional element have different colours and/or different optical properties, and, at least in a part of three-dimensional elements the similarly oriented (in one direction) surface sections of different three-dimensional elements have a similar colour and/or similar optical properties.
  • the similarly oriented surface sections of different three-dimensional elements have a similar colour and/or similar optical properties.
  • the differently oriented surface sections of each three--dimensional elements including the surface section between the adjacent three-dimensional elements have at least three different colours and/or three different optical properties, and, when use is made of three colours of the differentlx oriented surface sections of the three--dimensional elements, preference should be given to three main colours: red, blue and one of the colours of the yellow, yellow-green and green colour group.
  • the texture surface is made in the form of regularly arranged projections and/or hollows representing the three-dimensinal elements whose three sides are similarly oriented in all the elements whereas the aides of each element are separated by ribs converging in a peak, the sharpness of the ribs and the peak being characterized by the ratio of the three-dimensional element height to the rounding radius of its ribs and peak lying in the range from 3 to 300, while each of the three sides has the colour and/or optical properties differing from those of the other two sides.
  • the texture surface may also be made in the form of alternating three-faceted projections and hollows each facet whereof is made flat.
  • the invention allows obtaining a basically new decorative material possessing colourdynamic properties.
  • the face colour of such a material changes in a wide range depending on a visual angle at which it is looked at.
  • a ceramic plate can look red, orange, yellow, green, blue and violet when observed from different visual angles. Any other set of colours or the order of their distribution may be designed.
  • the material actively responds by changing its colour to the change of the angle of natural or artificial illumination.
  • the colour of a colourdynamic wall of a building changes constantly in the course of the day if looked at from one visual position. It is orange--red in the moring, violet in the day time and blue-green in the evening.
  • the left part of the building may look red
  • the right, bottom and top parts may, respectively, look blue, yellow and violet, the colours shading imperceptibly into each other at the boundaries of the parts.
  • a colourdynamic surface reveals and emphasizes the nature of the architectural shape the way light and shadow do this.
  • a cylinder becomes “rounder”, a cube "more faceted”.
  • the similarly oriented and frequently repeated architectural elements such as balcony planes, faces of buildings etc., begin to differ in colour, and to form colour lines thus considerably decreasing the feeling of their monotony.

  • the said ratio should not be less the 3, since in case of smaller values the quality of the light separation in the perception of the surface is considerably degraded.
  • the upper limit 300 is characterized in that the further decrease of the rounding radius of the peaks relative to the height of the elements, i.e. the further increase of the sharpness of these peaks has no effect on the colour separation quality and longer but impairs the operating characteristics of the surface creating an increased probability of chipping and breaking the peaks of the three-dimensional elements.

  • the surface colour is determined not only by the observer's position but also by the light flux direction, since the brightness of the illuminated colour sections may many times exceed that of the shaded sections.

  • Colourdynamic materials may be obtained using both regular textures and lattices with linear, round, aquare, faceted and other regularly arranged cells and elements and irregular ones, for instance, the surfaces with a gravel or developed sand texture, the surfaces of various foam materials, such as foam concrete, foam glass, foam plastic, porolon, etc., the textures of many types of pile, looped and cellular cloth as well as nonvowen synthetic materials.
  • the first method very universal and widely used in industry, consists in that the texture surface is formed of three-dimensional elements with the ratio of the total area of the surface of all three-dimensional elements and of the intervals between the bases of these elements to the area of the surface on which the elements are located ly lying in the range from 1.2 to 24 and the ratio of the three-dimensional elements mean height to the main rounding radius of their peaks being in the range from 3 to 300, whereupon the different colours and/or different optical properties are imparted to the differently oriented sections of the three-dimensional elements in such a way that similarly oriented sections of the different three--dimensional elements have a similar colour and/or similar optical properties.
  • the second method differs from the first one by the fact that the three-dimensional texture elements are formed from the sections to which different colours or optical properties were preliminarily imparted, with the ratio of the total area of the surface of all three-dimensional elements and of the intervals between the bases of these elements to the area of the surface upon which these elements are located lying in the range from 1.2 to 24, and the ratio of the three-dimensional elements means height to the mean rounding radius of their peaks being in the range from 3 to 300 so that the similarly oriented sections of different three-dimensional elements acquire a similar colour and/or similar optical properties.
  • the method may be considered as the main one since it is most universal and efficient, however, it calls for a precise selection of dye spraying modes for each particular texture and steady maintenance of these modes throughout the production process.
  • a dye may be deposited both manually and with the aid of various pulverizers but it is less efficient in comparison with the previous method and is used mostly in dyeing the regular texture surfaces and lattices.
  • an article in the vacuum chamber is positioned at an angle to the parallel stream of precipitating particles.
  • a natural colour of a material for instance, red colour of the facing brick or light colour of a bleached fabric may be used as a component of the material colour in production of some colourdynamic materials.
  • the second of the two proposed methods of obtaining the raster decorative colourdynamic texture surfaces consists, like the first method, of two main production operations:
  • texture forming elements may be depending on the problem to be solved various parts and articles, such as small--size colour ceramic plates, preliminarily coloured metal of polymeric plates, elements of a flat colour raster, (paper raster, for instance) colour thread and other articles.
  • variable colour raster surface of a safety panel may be obtained as a result of a mechanical or automated placing of ceramic colour plates against a form provided with an appropiate relief of the lower surface.
  • the plates of one colour are oriented in one direction. After all the plates and necessary fittings are placed in the form, the latter is filled with concrete.
  • the article extracted from the form after aquiring the necessary strength represents a panel faced with ceramic plates with a variable colour surface.
  • the construction parts of the lattices may function as relief forming colour elements. Used as such elements can be metal strips painted in different colours on both sides and provided with equally spaced slots to receive differing in colour but otherwise identical metal plates at some angle during assembly. For instance, in assembly of a vertical lattice with aquare meshes, the vertical plates may be fainted red and green and the horizontal ones, blue and yellow. In this case, each mesh will be represented by four colours corresponding to four sides of a square - red, yellow, green and blue.
  • colour elements can be not only straight but also bent plates or individual relief elements.
  • Colourdynamic surfaces may be also obtained by corrugating (crimping) or extruding the texture on per-piece, roll and sheet materials provided with a preliminarily printed colour raster.
  • the colour raster may be printed by traditional in particular, typographical methods and the texture may be formed by pressing the per-piece articles with relief punches or by rolling the roll and sheet materials between texture forming shafts.
  • the second method of obtaining the raster variable-colour surfaces may be of a particular importance in the production of a variety of colourdynamic fabrics, knitted goods, carpet coatings etc. because it allows obtaining a special purity of component colours provicded the manufacturing process is automated and, respectively, achieving a high productivity.
  • variable-colour surface After a variable-colour surface is obtained, a wide variety of materials may be given a special translucent protective layer.
  • the face of a colourdynamic ceramic of glazed concrete plate may be given a coat of a transparent glaze applied in a layer 22 ( Figure 11) which completely or partially conceals the texture of the plate.
  • the coat may be, respectively, rather thin.
  • the glass facing plates ( Figures 1, 2) may have a colour texture on the inside providing simultaneously a good cohesion of the plates with concrete or mortar and a smooth surface. An effect of light Variation, in this case, is percepted by observing the appearance of "day light" through a transparent glass layer.
  • Some decrease of the light-variation activity of such materials occuring as a result of the light refraction in the translucent layer and causing a visual flattening of the texture three-dimensional elements may be compensated for by a respective decrease of an actual texture factor of the surface being coloured.
  • Such a layer can be obtained by fusing, glueing or otherwise securing the sheet translucent material to the texture surface or lattice.
  • An embodiment of the present invention is presented a method in which a texture surface is formed at the beginning and then various substances including different colour dyes are deposited by spraying an an angle to the main surface of the material onto the differently oriented sections or the texture three dimensional elements.
  • the main advantage of this method consists in high productivity and universality which allows obtaining the diverse colourdynamic materials with regular and chaotic textures.
  • the simplest is a class of linear three-dimensional elements 7 ( Figures 4, 5), having a prismatic or any other extended shape and located parallel to each other.
  • each three-dimensional element should be painted in different colours on two sides.
  • the decorative merits of this embodiment are not high since the colour variation effect is limited by a narrow colour range consisting of two components.
  • linear textures consists in the fact that in case of a vertical arrangement of extended material, the latter are much less subject to contamination in use in comparison with all other textures.
  • a colour-variation effect of the linear texture surfaces is a one-coordinate and due to this principally limited.
  • the vertical component is not present in the colour expansions occuring on the architectural and other forms and also on the three-dimensional forms when use is made of linear textures with vertical elements.
  • the linear texture materials are limited inttheir combination Potentialities since subject to the condition that the three-dimensional elements 7 ( Figures 4, 5) are vertical, only two positions of the material on the vertical surface are possible.
  • the second class of the three-dimensional elements included all the diversity of non-linear elements forming both regular and chaotic texture surfaces and lattices ( Figures 1, 2, 6, 7).
  • Trihedral elements 16 ( Figures 9, 10) fall into a special group of the second class of non-linear three-dimensional elements which compare favourably with all other elements by production and performance characteristics. It should be noted that the presence of three colour components is a necessary and sufficient quantity providing for a full-value two-coordinate colour-dynamic effect and quite a wide range of additional colour mixings up to the full set of spectrum colours. Therefore, the textures illustrated in Figures 9 and 10 consisting of the trihedral three-dimensional elements 16 are highly competitive with the described above textures ( Figures 1, 2, 6, 7) in decorative and combination potentialities and compare favourably with them in their capacility to ensure a high quality of colour separation during deposition of dyes.
  • the textures having the trihedral elements are considerably less subject to contamination in use since there exist three possible positions of the three-dimensional elements on a vertical surface which have no horizontal sections of the prone to quick contamination.
  • the three-dimensional elements 1 of the texture shown in Figures 1, 2 have sections 5 inclined at 60° to the vertical plane
  • the three-dimensional elements 16 of an identical texture so fas as colourdynamic activity is concerned illustrated in Figures 9 and 10 have sections 18 and 19 inclined to the vertical plane at an angle of 30°. That is, the almost horizontal sections (inclination of 60° ) are replaced in the second case with the almost vertical sections (inclination of 30°).
  • the texture elements of its surface should be fine enough to ensure the basic characteristics of its perception.
  • the three-dimensional texture elements whose height is 10 to 12 mm and less.
  • a major advantage of the second method consists in a high quality of colour separation when using the scale of gradation of component colours.
  • disadvantages of this method are its relatively lower productivity and poor versatility, since each kind of material, when using this method, calls for its individual production process and, respectively, individual fixtures, appliances and equipment.
