Abstract

PURPOSE:To provide desirable nonflammability and to facilitate working and mass production by forming a foaming layer in which glass fiber is uniformly dispersed in phenol resin and inorganic powder on the surface of a nonflammable board, molding continuous joint grooves on the surface, then arranging a decorative material on the surface, and high pressure press-molding it in an uneven pattern shape. CONSTITUTION:After a foaming layer 2 in which glass fiber is uniformly dispersed in phenol resin and inorganic powder is formed on the surface of a bendable nonflammable board 1 made of glass cloth, nonflammable paper material, etc., tile matrixlike continuous joint grooves are formed on the layer 2 by cutting. Then, a surface decoration 4 such as a veneer, firefighting paint, etc. is provided on the surface, high pressure press-molded in a protrusion pattern shape, and thermally cured, thereby manufacturing a nonflammable decorative material 5. Thus, the material 5 having excellent workability and mass productivity, good external appearance, and design effect of heavy feeling is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a non-combustible decorative molding method for non-combustible decorative materials used for decorative materials for buildings, vehicles, etc., partition materials, etc.

[Conventional technology]

As a decorative method for decorative materials such as interior wallboards, for example, in the case of decorative boards with a tile-like surface pattern, a method is known in which surface decoration is applied to the wood base material and then cutting is performed on the tile joints, etc. Another cosmetic method is to apply various surface colors or patterns to a thin flame-retardant resin plate by printing or the like.

[Problems with conventional technology]

However, those that use a wood base are not suitable for locations that require a fire-resistant structure, have poor workability and are not suitable for mass production, and when V-cuts are made, the wood base is exposed at the joints. On the other hand, since the flame-retardant resin board is just a printed pattern, it lacks a sense of volume and gives the impression that it is cheap as a decorative material. Ta.

[Problem to be solved by the invention]

In view of the above-mentioned problems, the present invention was made for the purpose of providing a method for molding non-combustible cosmetics that has good non-combustibility, is easy to process and mass-produce, and provides a voluminous appearance. .

[Technology that led to solving the problem]

That is, the method for molding noncombustible cosmetics of the present invention involves forming a foamed layer in which glass fibers are uniformly dispersed in phenolic resin and inorganic powder on the surface of a noncombustible substrate, and then cutting continuous grooves on the surface of the foamed layer. After molding, a decorative material is provided on the surface and high-pressure press molding is performed to form an uneven pattern.

〔Example〕

Next, the present invention will be explained in detail.

FIG. 1 is a perspective view of an embodiment of the invention.

The non-combustible cosmetic molding method of the present invention includes a foam layer 2 formed by uniformly dispersing and mixing glass fibers into phenolic resin and inorganic powder on the surface of a bendable non-combustible substrate l such as glass cloth or non-combustible paper material. After forming, continuous grooves similar to tile joints are formed on the surface of the foam layer 2 by cutting, and then a surface decoration 4 such as veneer or fireproof paint is applied to the surface and high-pressure press molding is performed to form a convex pattern. The non-combustible decorative material 5 is manufactured by heating and curing.

(Function) According to the non-combustible cosmetic molding method of the present invention, a decorative material that is stable in strength and bendable can be obtained by high-pressure pressing and heating hardening the foam layer 2 mixed with glass fibers. In addition, phenolic resin is thermosetting,
Flame retardancy and non-combustibility can be ensured by containing crystal water inside and the inorganic powder absorbs heat, and since it can be manufactured using a grinding process and a high-pressure press molding process, it is easy to manufacture and mass-produced. It will be suitable for

In addition, since the convex pattern 4 is attached to the foam layer 2, the convex pattern has a three-dimensional window, and a decorative surface with volume is obtained.
In addition to this three-dimensional shape, by forming the convex pattern 4 into a curved surface, it is possible to make the base surface in the joint portion 6 less noticeable.

(Effects) As explained above, if the non-combustible cosmetic molding method of the present invention is used, it is suitable for use in fire-resistant structural parts, has excellent workability and mass production, and has a design effect with a heavy appearance. Non-combustible decorative materials can be produced.
