JPH04148924A - Sheet material having irregular surface and manufacture thereof - Google Patents

Abstract

PURPOSE:To obtain a sheet material having a recess and protrusion surface which is full of a natural impression and excellent in its design, and provide a process for producing the sheet by a method wherein powdered/granular materials, particularly those of inorganic substances, are integrally applied to large irregular patterns which a synthetic resin layer forms on the surface of the sheet material, thereby giving an mineral-like feeling thereto. CONSTITUTION:A base material to be used is such that, for example, paper, an unwoven cloth and the like, or a sheet material prepared by applying either foaming or nonfoaming synthetic resin paint in advance to the entire surface thereof. Then, either one or at least two kinds of the powdered/granular materials or scraps of a synthetic resin, the powdered/ granular materials of an inorganic substance, or short fibers (hereinafter called a spray material) are sprayed onto the base material. After spraying, the base material to which the foaming paint has been used is foamed, while the base material to which the nonfoaming paint has been used is melted under heating and, thereafter, the base material is embossed to finish all processing steps. Thus, the sheet material having an irregular surface has thereon the mingled and integrated irregularity formed by different forming means, whereby its irregular surface has a very complicated pattern. Therefore, when it is used as a wall decorative material or the like, the sheet material is effective in creating an atmosphere full of a natural feeling.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Application of the Brow 18 The present invention relates to a non-woven material having an uneven surface (more specifically, it relates to a material having an uneven surface due to mechanical embossing and a powder grain material). It has a natural-looking uneven surface created by a combination of unevenness on the body, etc., and is mainly used as wall material.

<Prior Art and Problems> Conventionally, notebooks with various surface sensations have been provided.

It is known that it is the No. 1 material that is particularly useful as wallpaper, and it has a sandy surface feel. For example, No. 1" 4 is well known, which has a surface of 11911 by combining a foamed synthetic resin layer and a powder material such as an inorganic substance or synthetic resin.

JP-A-1-97641 discloses that the four sides are completely coated with iV foamable synthetic resin paint, the upper and lower sides are embossed, and then the foamable synthetic resin is applied in a desired pattern on each side. A notebook material is disclosed in which a resin paste paint is applied, fine pieces of synthetic resin are sprinkled on the foamed resin-based paint 1 before it dries, and then a foamed layer 1 is applied.

Jikai/Fl-97642- discloses a notebook material made by sprinkling fine pieces of synthetic resin on foamed 11 synthetic resin paste paint applied in a pattern, and then foaming. There is.

However, the protrusions mentioned above are the asperities formed by the combination of the unevenness caused by foaming and the unevenness formed by minute pieces of synthetic resin. It has a structure that adheres to the surface of the foam layer, so there is no sense of unity between the fine pieces of synthetic resin and the foam layer.Also, the complexity of the unevenness is not that complicated, and it has a natural feel. Damono and Ll
My knees are so hot.

<Problems to be Solved by the Invention> The present invention solves the problem of a large uneven pattern formed by a synthetic resin layer having a pine body, especially 411! The organic substance nomu] also has a rich sense of nature by adding an inorganic Yoimiya by integrating one body (white 1 + i is f, hei 31 is an uneven surface /-1-
This is a task to solve the problem of materials +1j.

<Means for Solving the Problems> The present invention provides a method of applying a foaming paint or "1-foaming paint, l, to old wood on the entire surface or in a pattern," and applying this paint f1.
By applying powder or granular materials such as inorganic substances to a thin cloth, drying or foaming the material before it dries, and then drying or foaming, each time the embossing process is applied, a complex surface texture is always created. The company provides sheet materials.

In the present invention, the following steps are carried out in this order: applying coating 1 to the left hand, spraying and adhering powder such as inorganic substances, drying or foaming this coating layer, and then embossing. However, it has certain characteristics. In other words, by drying, foaming, and then embossing after dispersing powder and granules, part or all of the powder is press-fitted into the paint layer, and the adhesion of the powder and granules to each other is improved. At the same time, the unevenness peculiar to the powder and granular material that is dispersed and adhered and the unevenness of the synthetic resin layer itself expressed by embossing are not simply overlapped, but two types. The coexistence of the different types of unevenness described above makes it possible to provide a surface unevenness that has a natural feel that goes beyond the surface feel of a simple self-reflection resin.

The base material used in the present invention is not particularly limited, and for example, paper, nonwoven fabric, etc., or Nohi A, which is coated all over with synthetic H + oil paint, etc., can be used. As a result, either foaming or foaming t1 is applied to the base material 7, but this application may be either full-length application or partial pattern-like application 4I. In particular, partial patterns (in the case of cover coating, T after the second step)
By sequentially overlapping the culms, compared to the case of full-surface application, - layer? A MM uneven pattern surface is formed i4).

The synthetic resin that is the main component of the coating in the first step is mainly polyvinyl chloride, but examples include vinyl-vinyl acetate copolymer.

In preparing this paint, plasticizers, stabilizers, colorants, etc. are mixed as necessary.

In the first step - which application F&J, one or more of the following (hereinafter referred to as the "sprayed material") is sprayed: synthetic resin powder or debris, inorganic material 'a powder or short fibers, or short fibers. However, the first period of this spraying is not only immediately after applying either foaming or non-foaming paint, but also after applying the paint, gelling it, then applying appropriate coloring or pudding to this surface, and spraying on this surface. In some cases, the IW cloth is applied while the material is still wet.

In the present invention, after this spraying, foaming l! ,, Add 8, if you use IJ foam paint! V7 is melted, and then 11 embossing is applied to complete the entire process. This is then embossed to complicate the unevenness of the surface, but if the paint used in the first process is a foamed paint, the spraying condition in this first step may be partially uneven. If it is patterned, it is more −
- A surface condition with complex layered unevenness is formed.

In other words, by combining the following four processes: ■ Weighting by foaming ■ Unevenness by partially patterned fabric ■ Roughening by scattering ■ Unevenness by embossing, it is extremely complex and rich in natural feel. It is possible to form surface conditions.

As already mentioned, the materials used in the present invention include synthetic resin powder or waste, inorganic material powder, short fibers, etc. The synthetic resin powder or waste includes, for example, In addition to polyvinyl chloride grains, various synthetic resin beads, etc., it also includes waste materials such as pulverized waste and cut film waste, and those containing a blowing agent are also available. Also,
The granular material of an inorganic substance includes not only vermiculite but also crushed stone waste, and short fibers also include so-called fiber waste.

4] The method is not particularly limited to this, but the complexity of the surface of the seam A obtained by adjusting the amount of spraying material (loser] III density) can be controlled to some extent.

<171 River> The present invention is directed to the entire or partial application of foamable or Jl-foaming paint on the base material surface and the scattering of the sprayed material on this coating layer. Processing, gelling or foaming - ``processing and embossing process are two steps, and these steps are carried out sequentially to provide the first shrine.
On each T culm, l, h (1,1J) have unique unevenness,
- An extremely complex (concave and convex surface) is formed on the surface of the notebook by combining the two surfaces.

Particularly, on the paint 1r cloth on the base material side, apply this partially;
By making the coating layer 1 foamable, more complex unevenness can be formed.
