More specifically, the present invention relates to a resin molding template having an uneven pattern on the surface of a high-strength, dense hydrate cured product obtained using hydraulic cement, an organic polymer, or a copolymer. [Prior Art] Conventionally, a casting method or a resin grouting method is generally used as a method for manufacturing artificial stone. Metallic materials such as low-melting point alloys, cast iron, and steel have been used as materials for this imposing type. [Problems to be solved by the invention] However, many of these have smooth surfaces;
In order to create an embossing type with an uneven surface, it is necessary to process it by etching or electric contact, and such processing is complicated, takes a long time to manufacture, and is expensive, so it is difficult to use metal.

The fact that the above hydrated cured product can be obtained is, for example,
This method is known from Publication No. 9-4343 1, Japanese Unexamined Patent Application Publication No. 129853/1980, etc. In this invention, we focus on the high bending strength and dense structure of this high-strength permanent cured product, and aim to provide an economical and simple resin molding template with good transferability. It is something. [Means for Solving the Problems] The product is made of at least one type of hydraulic cement and a water-soluble or water-dispersible organic polymer, or a water-soluble or water-dispersible copolymer, and has a bending strength of 350 Kgf/cm2 or more. In the cured hydrate body of
A 10mm resin molding template is used. The method for producing a cured aqueous material having an uneven pattern on its surface according to the present invention will be described below. 0.5 to 10 parts by weight of a water-soluble or wood-dispersible organic polymer or copolymer, 8 to 10 parts by weight, based on hydraulic cement such as ordinary Bortland cement.
Add 15 parts by weight of water and other additives, knead using a roll mill, etc., and then shape into a sheet using a calendar roll. Instead of a roll mill, e.g. For example, a zl mixer can be used under vacuum. In particular, when pressed using a combination of a roll mill and a calendar roll, a dense molding plate with fewer pores in the cured hydrate can be obtained.

ならない。Furthermore, in order to obtain high strength, it is preferable to perform heat curing after heat pressing. Hydraulic cements include boltland cements such as ordinary boltland cement, white boltland cement and early-strength boltland cement, mixed cements containing blast furnace slabs, fly ash and silica fume, alumina cement and gypsum in large amounts. Special cement can be used. As water-soluble or water-dispersible organic polymers or copolymers, amide-substituted polymers such as acrylamide polymers, cellulose ethers such as hydroxylpropyl methylcellulose, polyvinylhydrin, polyethyl oxide, etc. can be used. Particularly preferred is partially hydrolyzed polyvinyl acetate. These have the effect of assisting in the kneading and shaping properties when producing a cured hydrate body, and are essential for obtaining a dense and high-strength cured water body. By adding high boiling point polyols such as glycerin and polyalkyl glycol, the kneading and moldability is further improved, and the addition of glycerin is particularly effective. Other fillers that do not contain coarse particles, such as calcium carbonate, silica fume, silicon carbide, and carbon. Alumina and metals may be added as necessary. In particular, adding hard materials such as silicon carbide and alumina improves wear resistance and greatly increases the number of times the mold can be used repeatedly. It is preferable that these fillers do not substantially contain particles of 100 gm or more, since if the particle size is large, the surface of the permanent cured product will be roughened. Furthermore, asbestos, glass fiber, etc. can be used as the fibrous filler, but it is necessary to avoid using one with a large wire diameter or using a large amount even if the wire diameter is small, since this will roughen the surface.

め好ましくない。After sufficiently kneading these compounds with a roll mill, etc., the resulting sheet is rolled with a calendar roll, etc., and one or both sides are coated with a material having desired unevenness, and the sheet is rolled for 10 to 50 kg.
After transferring the uneven pattern to the sheet by pressing at a pressure of gf/crrf at room temperature to 150°C, the sheet is cured to obtain a mold for the permanent cured product. This mold has a bending strength of 350 kg.
It has extremely high strength of more than f/cm', is dense, and has excellent hardness. The thickness of the mold of the present invention is preferably 2 mm to 10 mm. If the length of the mold is 600 mm or more, for example, when used as a partition material in the resin grout method,
When filling with filler such as granite with a thickness of 2 to 4 mm, the mold deforms and a product with a constant thickness cannot be obtained.
If the thickness exceeds m or more, the weight becomes large and handling when setting and removing the formwork becomes inconvenient, which is not preferable.

Can be used for methacrylic resin, polyamide resin, etc. Since the molding template created by the wood invention has high strength and excellent abrasion resistance, even if the mold is set, poured, solidified, and released repeatedly, the convex part of the mold will not be damaged or deformed due to wear. Less is. Furthermore, although the use of a solvent is essential for these series of operations, the mold of the present invention has excellent solvent resistance, so the uneven surface condition can be maintained for a long period of time. Furthermore, since the compact mold of the present invention is dense, the injected resin does not easily penetrate into the mold, resulting in excellent mold releasability. In addition, commonly used mold release agents such as oil-based, surfactant-based, silicone resin-based, and fluororesin-based mold release agents used in resin molds can also be used.

う利点がある．In addition, coating materials that have high hardness and can form thin films,
For example, an inorganic coating film such as a thin film obtained by hydrolysis/heat treatment of a metal alcoholate may be preformed on the mold. [Example] Next, an example of the present invention will be shown. Note that the present invention is not limited to the examples. [Examples 1-2, Comparative Examples 1-3] Alumina cement and ordinary Boltland Shichimen}10
0 parts by weight, 7 parts by weight of partially oxidized polyvinyl acetate, 0.7 parts by weight of glycerin, and 14 parts by weight of water were mixed in a planetary mixer, kneaded in a roll mixer, and shaped into a sheet with a calendar roll. Temperature 80℃ and pressure 30
kgf/crn' for 10 minutes, cured at a temperature of 20"O for 24 hours, and then heat cured at 80°C for 10 hours to obtain a cured hydrate body.The cured body of this example and For comparison, commercially available building materials manufactured from hydraulic cement and hydraulic materials were taken up as comparative examples.
Table 1 shows the results of measuring bending strength, bending modulus, and 24-hour water absorption. The low 24-hour water absorption shown in Table 1 indicates that the cured product is dense. [Example 3] Example 3 is a granite hardened body produced in the same manner as in Example 1 except that 70 parts by weight of alumina cement and 30 parts by weight of α-alumina are used as fillers for artificial stone. The hardness (Vickers hardness) and the amount of wear resistance (amount of wear caused by the wear wheels of the Taber method) were compared and measured. The results are shown in Table 2. Table 2 *r5) Marble from Italy (Travertine Romano)
[Example 4] In Example 4, cured hydrate bodies produced in the same manner as in Example 1 were immersed in various solvents, and the bending strength and bending elastic modulus were measured after 7 days and 28 days. . The results are shown in Table 3. (Hereinafter, blank space) Next, an example of usage will be shown. First, the material having the uneven pattern was applied to the cured hydrate body during hot pressing in Example 1 to produce five cured hydrate bodies (one of which had unevenness on both sides) to which the uneven pattern was transferred. These are placed in the formwork 1 shown in Figs. 1 and 2 at the location shown in 2 as a partitioning material, that is, a template for molding. frame stone)
Next, a binder (100 parts by weight of unsaturated polyester, 1 part by weight of lauroyl peroxide, and 0.1 part by weight of carbon black) was injected, solidified (at 90°C for 2 hours), and mold release was repeated 100 times. ．． As a result, no deformation of the resin molding template 2 or wear of the convex portions was observed. [Effects of the Invention] The resin shape template of the present invention is easy to manufacture and has particularly excellent transferability, so that a drawing die having an uneven pattern can be manufactured at low cost. In addition, because the bending strength is extremely high, the thickness of the mold can be made thinner, and the weight is lighter, making it easier to handle.Furthermore, since it is a dense material, there is no penetration of resin, etc., and mold release is smooth. Furthermore,
Due to its excellent wear resistance, it can be used repeatedly,
It also has the advantage of being able to maintain its uneven pattern for a long period of time because it has excellent properties as a liquor solvent.
