Embodiment 1

[0033] This example illustrates the artificial stone composition of the present invention, the composition, the artificial stone, and the method for producing an artificial stone molded article.

[0034] 100 grams of methyl acrylate, 75 grams of aluminum hydroxide (Guangzhou Qingkai Chemical Co., Ltd., toothpaste grade, 20 microns), 0.1 gram of methyl ethyl ketone peroxide (Guangzhou Qingkai Chemical Co., Ltd.) and 0.5 grams of defoamer ( BYK515 produced by BYK Chemicals Co., Ltd.) and stirred for 15 minutes under a vacuum of 0.01 MPa to obtain a mixture. Then directly pour the mixture into a mobile phone button mold (manufactured by Shenzhen BYD), and keep it at 100° C. under a pressure of 50 kgf for 30 minutes. Release the mold to form a mobile phone button, and then use a printing machine (Ronglong Precision Machinery Co., Ltd., UP-121-YA) to print the number "1" on the button. Then use a punching machine (Liwei Automation Technology Co., Ltd. (Shenzhen) Co., Ltd., CH-108)...

Embodiment 2

[0036] This example illustrates the artificial stone composition of the present invention, the composition, the artificial stone, and the method for producing an artificial stone molded article.

[0037] With 100 grams of methyl acrylate, 300 grams of aluminum hydroxide (Guangzhou Qingkai Chemical Co., Ltd., toothpaste grade, 30 microns), 12 grams of methyl ethyl ketone peroxide (Guangzhou Qingkai Chemical Co., Ltd.), 10 grams of defoamer and 5 g of cobalt naphthoate were mixed and stirred for 25 minutes under a vacuum of 0.01 MPa to obtain a mixture. Then directly pour the mixture into a mobile phone button mold (manufactured by Shenzhen BYD), and keep it at 100° C. under a pressure of 50 kgf for 6 minutes. Release the mold to form a mobile phone key, and then use a printing machine to print the number "1" on the key. Then use a punching machine to punch, cut off the leftover material of the button, and obtain the artificial stone shaped product of the button of the mobile p...

Embodiment 3

[0039] This example illustrates the artificial stone composition of the present invention, the composition, the artificial stone, and the method for producing an artificial stone molded article.

[0040] 100 grams of methyl acrylate, 260 grams of aluminum hydroxide (Guangzhou Qingkai Chemical Co., Ltd., toothpaste grade, 40 microns), 1 gram of methyl ethyl ketone peroxide (Guangzhou Qingkai Chemical Co., Ltd.), 2 grams of defoamer, 10 grams of cobalt naphthalate and 40 grams of polymethyl acrylate (Shanghai Tiou Technology and Trade Co., Ltd., LG PMMAIH803 series high-impact series, weight-average molecular weight 50000) were mixed, and stirred for 25 minutes under a vacuum of 0.05 MPa to obtain mixture. Then directly pour the mixture into a mobile phone button mold (manufactured by Shenzhen BYD), and keep it at 100° C. under a pressure of 50 kgf for 5 minutes. Release the mold to form a mobile phone key, and then use a printing machine to print the number "1" on the key. Th...

Abstract

The invention relates to an artificial stone composition, wherein, the composition contains a monomer, a filler, a curing agent and a defoamer, the monomer is (methyl) acrylic ester, compared with 100 parts by weight of the monomer, the content of the filler is 75 to 350 parts by weight, the content of the curing agent is 0.1 to 15 parts by weight, and the content of the defoamer is 0.1 to 25 parts by weight. The artificial stone which is obtained by the invention has natural texture, beautiful patterns, good transparency and high material strength, thereby having very high added values.

Description

technical field [0001] The present invention relates to an artificial stone composition, the composition, artificial stone, and a method for manufacturing artificial stone shaped articles. Background technique [0002] Artificial stone was first manufactured by DuPont in the United States. It has the usual appearance of granite or marble and can be used as a variety of decorative materials. [0003] In the past, the method of artificial stone was generally prepared by mixing and melting resin polymers and fillers in a certain proportion, but usually the viscosity of the resin in the molten state was relatively high, which easily made it difficult for fillers or other additives to mix uniformly, and Usually, in this preparation method, the resin polymer and the filler are combined in a physical connection, so the strength of the obtained artificial stone cannot meet the requirements, which will undoubtedly lead to a decline in the quality of the artificial stone. Simultaneo...
