CONSTITUTION:100pts.wt. resin prepared by mixing 10-70wt% bisphenol vinyl ester resin with 30-90wt% unsaturated polyester resin is incorporated with preferably 50-250pts.wt. aluminum hydroxide as a filler, 10-30pts.wt. (meth) acrylic acid ester of tris (2-hydroxyethyl) isocyanurate, a hardener, e.g. benzoyl peroxide, an inhibitor, e.g. p-benzoquinoe, a low-shrinkage agent, e.g. polyethylene, etc. to give a sheet molding compound or bulk molding compound, which is then molded to give the aimed artificial marble. EFFECT:Improved surface hardness.

Description

[Detailed Description of the Invention] Transparency, surface gloss, and darkness of FffSMC (Sheet Molding Compound) and 1πHBMC (Bulk Molding Compound)! The present invention relates to a method for manufacturing artificial stone that has been precisely ground.

SMC and unsaturated polyester but also carbonic acid, etc. (/J Wuyihishinghong wholesale), Ento Tang type Oki 1.1 generation supply wholesale'', shield coloring agent, viscosity agent and oil included. It is a type of material that is impregnated into a glass horizontal string, wrapped in film, made into a sheet, aged and made into a semi-solid shape. After the film was damaged in January, the VC was placed on the mold, and the press molding tool was placed on the stack 1.In addition, BMC and SMC were kneaded with various types of losers. S is a liY-shaped material made into a lump.

11. It is easy to form a complex shape θ with lJ, and it fits the subject matter. It is widely used in the field of gods.

However, with regard to Hitotsugu Marble V, which has recently seen an increase in clean copies,
Since MC and BMC do not have transparency in their molded products, the unique translucency of marble requires deep processing. The current situation is that we rely on the non-dryup method.0 By the way, recently, what has been done for various purposes? For example, in anti-blood vanity tables, sink counters, etc., in addition to transparency, it is desired that one secret is not easily attached at one cost, and VCs are becoming very smart in their desire for tubes with n-surface hardness. The current situation is that even the casting method and the no-dry-up method are not completely satisfactory.

The above BMCMC1Bυ opacity was improved on the uninvented eye 1, and SMC, BMCVC transparency was added and VC was added.
,sMc, improved the surface hardness of BMC and reduced the surface hardness by %SMC,'!
We hope to make it possible to manufacture artificial marble using IcBMc, and further expand its applications by making it possible to create a hard surface.

In the R and Q fields, the number of Cu-based artificial marbles has been steadily increasing, and many Cu-based artificial marbles have been developed.

C is also a 5ν shaped product using beef flour and Japanese polynis del oil (q melamine makeup root, table U1fI hardness is lower than that of pottery l, and when the VL positive is attached to the 1st medium phase, it is just right) There is also the disadvantage of using foreign soil, and the situation has become such that there is no hope that 1J + Ai will also be charged.

1't'' transparency between CI+ and other two points Regarding VC, there is transparency in SMC and BMC molded products.
The refractive index of calcium carbonate, which is generally used as a resin and a filler, is generally different from the mold force of the second vc molding section (150 to 150°C). During the cooling process, stagnation occurs at the interface between the resin and the filler, or between the resin and the glass, and 6+Q is the main cause.

This point V? - Aluminum hydroxide as a filler first? The resin used is a general unsaturated polyester resin, which has a refractive index close to that of aluminum hydroxide, has excellent adhesion properties, and is resistant to interfacial peeling, making it transparent. sex 7
I discovered something great about improving people's behavior.

In the above invention, there is a transparent VL type molded product which is not present in conventional SMC and BMC molded products. @

The whiteness of aluminum hydroxide is preferably less than 20 μm because it is ubiquitous, and the whiteness of aluminum hydroxide has a negative effect on the whiteness of molded products, so white DJs and easily molded products are not recommended.

In the south of the end of the 6th capital, one more stone was added to the resin, which increased the cost, and the resin and filler were divided into parts.
This is because if the amount of wood is exceeded, the amount of wood withered IW will be high, reducing workability and further reducing the gloss of the molded product.
