Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a cosmetic hydration-cured inorganic board that has irregularities and patterns on its surface, has good performance and an excellent design, and a method for manufacturing the same in an extremely efficient manner. be.

In general, there are the following products and methods for applying cosmetics to water-curing inorganic materials, but all of them have problems.

(+1 Decorative gypsum board manufacturing method knowledge includes two methods: printing on base paper in advance and then pouring gypsum slurry to harden the gypsum to create a board, and printing directly after creating a gypsum board, or printing notes. There is a method of attaching a pattern by laminating it, but in either case, it has a major drawback in terms of design that it is not possible to make large irregularities appear on the surface, and for the former, base paper is used. Because of this, it is not possible to obtain a good print on the pattern.The latter can be expected to have a printing effect, but the surface υ) A1
Not only can you not expect a good experience, but the high cost and poor workability cancel out the benefits of printing.

(2) Painting on the molded object This is a method in which the molded object is molded to have unevenness in advance and then painted. Ordinary marking methods such as screens and thermal transfer methods cannot be used.Therefore, special marking methods such as octopus markings I11, etc.
Then, using vacuum lamination, the method for laminating the material and the printing sheet is limited 1). However, the former has the problem that the ink is resistant to abrasion and the top coat is not durable because the ink is hard on the surface. The problem is that it has to be kept at a constant VC1~)
) Both of these are fatal in terms of cost. The latter vacuum lamination method requires a large number of 41J frames for preforming the base material and the fifth layer, and also requires cheap equipment to integrate the base material and/or the base material itself.・3.(3) Molding and molding At the same time, a transfer sheet is formed using a special ink, and a hydrated and hardened slurry is poured into it, and the transfer is completed when the slurry hardens.
This method involves demolding, but this JJ method also uses a special ink, which results in high costs, the ink film cannot be made thick, the color of the material must be constant, and it is susceptible to wear. There are various problems such as the problem that the top coat is too weak and the top coat is required, resulting in high cost, and the transfer rIT capability is limited by the substrate.

Therefore, the inventors of the present invention have investigated the
・As a result of this research, we developed a method for efficiently manufacturing decorative inorganic boards at low cost by pouring hydrated and hardened slurry into pre-formed printed notebooks and integrating them with 7-t when the slurry hardens and dries. completed.

To explain the present invention in detail below, the present invention involves bonding a non-woven fabric to the back side of a sheet on which a pattern is printed, and molding the non-woven fabric into a desired shape by impregnating the non-woven fabric with an adhesive resin. , or mold it into the desired shape and then check the adhesion.
After impregnating with the resin, the hydration-cured slurry is molded into the molded body L1, and the molded body is cured and dried. The feature is that the plates are integrated - ``Cosmetic inorganic plate and its σ) manufacturing/, θ2 and σ).

The present invention will be explained in more detail below with reference to the drawings.

If the ink does not have alkali resistance or resistance to adhesive resin or inorganic hydraulic element H, (I)) σ
) It is desirable to use a surface material.

The transparent notebook il+ and the colored film (4) can be arbitrarily used as long as they have moldability and printability. Films, single-layer films such as polystyrene films, and composite films made by laminating two or more of these films can be used. J Any non-woven fabric can be used, but for fabric weight 15-50
A polypropylene nonwoven fabric that can be freely expanded and contracted by heating at a rate of about '-t/m' is preferred.

Next, as shown in Figure 2, the surface material (6) is molded into an arbitrary shape of the VC so that the nonwoven fabric is on the inside, and then an adhesive resin is impregnated into the nonwoven fabric to form a mold (8). 3. In this step, as shown in Fig. 4, the nonwoven fabric of the surface material (6) is impregnated with adhesive resin and then molded into an arbitrary shape (reverse &i to 5 and 5).

You may do so.
