Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a method of decoration. For more details,
In particular, the present invention relates to a method for easily forming decorations comprising thick letters and figures on vertical glass surfaces.

[Prior art]

Traditionally, paints and surfaces have been applied to the glass surfaces of buildings and automobiles, windowpanes, mirrors, etc., the surfaces of steel furniture, fittings, walls, etc., and the surfaces of objects coated with temporary decorative boards such as melamine resin and polypropylene. Their surfaces are decorated by drawing letters and figures in poster colors.

These letters and figures are usually painted by diluting a weather-resistant paint solution with a solvent and applying it directly to the surface of the object with a brush or roller and letting it dry, or by masking the surface of the object and applying the diluted solution to the surface of the object. Methods used include spraying the undiluted solution into a mist and removing the masking after drying.

However, in the former case, there is a problem in that it is difficult to apply a thick film because the paint drips, especially when the construction surface is vertical, and the work requires skill. In addition, especially when using several colors, there is a problem in that the equipment required for the work, such as containers, becomes large-scale.

In the latter case, as in the former case, there is a problem that not only is it impossible to attach a thick film, but also that the masking and peeling operations are time-consuming.

Furthermore, in any of the above methods, the decorative stock solution diluted with a solvent has strong adsorption and adhesion to the surface of the object, and the film is thin and weak, so it is difficult to erase letters and figures later. The problem is that it is extremely time-consuming, as it requires cleaning with solvent and water. In addition to these methods, there are also methods of gluing letters, figures, etc. made of paper, plastic, sponge, etc., but these methods are less convenient and
It is difficult to decorate curved surfaces, and it cannot be said to be a general method.

[Purpose of the invention]

The present invention is a brilliant new decoration method developed to solve the above-mentioned problems, and allows a thick film to be easily attached to any shape, and furthermore, drawn characters and figures can be easily erased. The purpose is to provide a decoration method that allows for

[Structure of the invention]

In order to achieve the above object, the decoration method of the present invention divides the interior of an aerosol container into a first chamber and a second chamber by a movable partition wall, and makes the first chamber contain a resin. The viscosity is 100~
A decorative stock solution containing a small amount of release agent and a range of 100,000 cps is filled, and a propellant is also filled in the second chamber, and the pressure of the propellant pressurizes the decorative stock solution through the partition wall. , by communicating the first chamber with the outside, the decorative stock solution is continuously discharged in an arbitrary shape from the injection port formed so that the cross-sectional area thereof is in the range of 0.07 to 7.06 ^mm2 , and the discharge is performed. The structural feature is that the decorative stock solution is fixed on the construction surface while maintaining the shape at the time of discharge, and can be easily peeled off.

Note that the term "continuously having an arbitrary shape" as used in the claims includes not only cases where the cross-sectional shape is circular but also continuously extending in various cross-sectional shapes such as rectangular and star-shaped.

Also, fixing while maintaining the shape when ejected means
When the discharged decorative stock solution is dried and solidified, it is dried and solidified with almost no change in the cross-sectional shape of the discharged state.

[Embodiment]

Next, the method of the present invention will be explained with reference to the drawings.

Figures 1 and 2 are a sectional view and a partially cutaway side view showing an example of an aerosol product used in the method of the present invention, respectively, and Figure 3 is an example of a decoration formed by the decoration method of the present invention. FIG.

The aerosol product shown in FIG. 1 has almost the same structure as a conventional double aerosol product, except for the contents and some structures.

That is, 1 is a button, and the button 1 is provided with a relatively long nozzle 1a, a hole 2 is bored in the nozzle 1a, and the hole 2 opens as an injection port 2a at the tip of the nozzle 1a. The button 1 is fitted onto the upper end of a stem 3, and the stem 3 is fitted into a valve 4. The valve 4 is attached to the upper opening of the pressure vessel 6 by a mounting cap 5. A flexible inner bag 7 constituting a partition wall is housed inside the pressure container 6, and the upper end of the inner bag 7 is caulked to the upper end of the pressure container 6 together with the mounting cap 5. Thereby, the pressure container 6 is moved into the first chamber 8 by the inner bag 7.
and a second room 9.

The first chamber 8 is filled with a decorative stock solution A, which will be described later, and the second chamber 9 is filled with a propellant B. Note that a valve 10 for filling a propellant is provided at the bottom of the pressure container 6.

The decoration method of the present invention is carried out in the following steps using, for example, the aerosol product shown in FIG.

First, the tip of nozzle 1a is made of glass (G in Figure 3).
While keeping the distance between the surface of the glass G and the tip of the nozzle 1a at about 0.1 to 1.0 mm, press the button 1. Next, a decorative stock solution discharged from the injection port 2a with a cross section similar to that of the spray port is applied to the surface of the glass, and the decorative stock solution that is continuously discharged is applied to the surface of the glass in order without changing the cross-sectional shape. Fix it thickly. In that case, the aerosol container is moved in the direction of the line while maintaining a distance from the surface of the glass. Thereafter, the method of the present invention is completed by drying the decoration drawn on the surface of the glass using the decorative solution.

The decorative stock solution used in the method of the present invention is a resin,
It is a highly viscous liquid composed of solvents, dyes, pigments, additives, etc. A small amount of a release agent is mixed into this decorative solution to make it easier to remove letters and pictures drawn on the surface of glass.

The viscosity of the decorative stock solution is selected in the range of 100-100000 cps. In particular, it is preferably about 500 to 10,000 cps. Although it is possible to discharge continuously even when the viscosity is 100 cps or less, it may cause dripping when applied to objects such as glass, the decorative solution may spread in the width direction, the wall thickness may become thin, or This is because it is difficult to obtain a uniform width.

In addition, if the viscosity of the stock solution is 100,000 cps or more,
This is because when used in the normal internal pressure range (2 to 5 kg/cm ² at room temperature), the speed of discharge from the button 1 becomes slow, making it difficult to draw decorative lines smoothly.

The injection port 2a of the button in the present invention has a cross-sectional area of
Selected in the range of 0.07~ ^7.06mm2 . For example, if the cross-sectional shape is circular, the inner diameter is 0.3 to 3.0.
The range is mm. Inner diameter is 0.03mm (cross-sectional area is 0.07
If it is smaller than 3.0 mm (7.06 mm ² in cross-sectional area), the discharge speed of the stock solution will be slow and it will be difficult ^to draw a line. This is because the amount of discharge per hour increases and the width of the line becomes thicker, making it difficult to draw the line. Note that the cross-sectional shape of the injection port 2a is not limited to a circular shape, and may be any shape such as a rectangle or a rhombus.

The speed at which the undiluted solution is continuously discharged needs to roughly match the speed at which the user draws letters or pictures, so the inner diameter of the nozzle should be adjusted as appropriate depending on the type of undiluted solution for decoration, the thickness of the line being drawn, etc. It is preferable to select the viscosity of the stock solution.

The decorative stock solution used in the present invention is composed of a resin, a solvent, a coloring agent, a release agent, etc., as described above.In the case of an alcohol-based stock solution that uses alcohol as a solvent, resins such as polyvinyl butyral, acrylic resin, and urethane resin are used. is used.
In an organic solvent stock solution using an organic solvent other than alcohol as a solvent, resins such as polyvinyl chloride, acrylic resin, and cellulose acetate are used. As the aqueous emulsion stock solution, resins such as polyvinyl acetate, acrylic resin, polyethylene, and silicone resin are used.

As the release agent, castor oil, active agent, glycerin, polyethylene glycol, etc. are used.
Further, a thickener (carboxymethyl cellulose, metal soap, etc.) may be added to adjust the viscosity of the stock solution, and it may be colored with a dye or pigment depending on the purpose.

Aerosol products used in the method of the present invention include those in which a movable partition wall is formed by an inner bag 7 as shown in FIG. It may also be configured as a movable partition wall.

The aerosol product shown in FIG. 2 uses a piston 11 that slides along the inner surface of the pressure container 6 in place of the inner bag 7 in FIG. 1, making it easier to keep the injection port 2a perpendicular to the vertical plane. Like nozzle 1a
Since the product is almost the same as the aerosol product shown in FIG. 1 except that it is oriented diagonally upward, corresponding parts will be given the same reference numerals and explanations will be omitted.

The aerosol product shown in Figure 1 has high corrosion resistance and is therefore suitable for use in, for example, aqueous emulsion concentrates, while the aerosol product shown in Figure 2 has high solvent resistance and is therefore suitable for use in, for example, alcohol-based concentrates. Suitable for use such as. However, you can use it without worrying about this.

〔Example〕

Next, the operation and effects of the method of the present invention will be explained with reference to Examples.

Example 1 25 parts of polyvinyl butyral (parts by weight, same below), 60 parts of ethanol, 8 parts of butanol, 5.8 parts of butyl cellosolve, 0.3 parts of glycerin, and plasticizer
1.0 part of thickener, 1.0 part of thickener, and 0.5 part of blue dye were mixed to obtain a stock solution with a viscosity of 30,000 cps. After filling this stock solution into the first chamber 8 of the aerosol product shown in FIG. Filled with 10g of propellant, aerosol valve 4
An aerosol button 1 having an injection port 2a with an inner diameter of 0.5 mm was attached to the stem 3 of the sample to produce an aerosol product.

Next, when I drew the grid pattern 12 shown in Figure 3 with the aerosol product nozzle 2a facing the surface of the glass vertically installed, the line thickness was 2 to 3 mm and the liquid flowed smoothly without dripping. I was able to draw. When the lattice pattern drawn on the glass surface was removed after one month, it was possible to remove the entire surface of the glass cleanly by simply grasping one line 13 with one's fingers and pulling it off without leaving any marks on the surface of the glass.

Example 2 25 parts of acrylic resin, 40 parts of toluene, 7 parts of butyl acetate, 25 parts of ethyl acetate, polyethylene glycol
0.4 parts of thickener, 1.0 parts of thickener, and 1.6 parts of red dye were mixed to obtain an organic solvent stock solution with a viscosity of 5000 cps. The stock solution is filled into an inner bag 7 made of a laminated film of polyethylene and nylon as shown in FIG. 6 and the outside of the inner bag 7, that is, the second room 9.
15 g of propellant consisting of 50 parts of Freon 12, 40 parts of Freon 112, and 10 parts of dimethyl ether was charged. Furthermore, the width of the stem 3 of the aerosol valve 4 is 10 mm.
An aerosol product was manufactured by attaching an aerosol button 1 having an injection hole 2 having a rectangular cross section (cross-sectional area: 5 mm ² ) with a height of 0.5 mm. When the aerosol product was used to draw the decorative letters ``Xmas'' on the curved glass of a car's rear seat, it was possible to draw a thick decoration with a clear outline, about 13 mm wide, neatly without dripping. Two weeks later, I peeled it off with my fingers and it came off cleanly.

〔Effect of the invention〕

According to the method of the present invention, thick decorations can be neatly drawn on the surface of an object without dripping, and letters, figures, etc. once formed can be removed extremely easily. Therefore, compared to the conventional method of drawing with a brush or masking and then spraying, the work of decorating windows and window glass, the work of decorating curved surfaces, and the cleaning work are greatly simplified. It has the remarkable effect of Therefore, the effect is particularly great when the decoration is changed frequently. Furthermore, the method of the present invention is an extremely useful invention as it allows decorations of arbitrary thickness and thickness to be easily obtained by changing the viscosity of the decorative stock solution and the shape and cross-sectional area of the injection holes. .
