Quartz stone with long-acting organic antibacterial performance

Abstract

The invention provides a long-acting organic antibacterial performance. The quartz stone comprises, by weight, 20 to 35 parts of quartz powder, 35 to 60 parts of quartz sand, 0.5 to 1 part of modifiedorganic silicon resin, 1 to 3 parts of a coupling agent, 1 to 3 parts of a curing agent, 2 to 5 parts of an organic antibacterial agent, 3 to 8 parts of a pigment and filler and 8 to 18 parts of unsaturated polyester resin. According to the invention, the micromolecular organic antibacterial agent is polymerized through a polymerization reaction, and the composition of man-made quartz stone is optimized, so the prepared quartz stone has more obvious and long-acting antibacterial and bactericidal performance and provides better guarantee for human health.

Description

technical field [0001] The invention relates to the technical field of artificial quartz stone plates, in particular to an organic long-acting antibacterial quartz stone. Background technique [0002] In recent years, in the preparation process of artificial quartz stone, artificial quartz is usually made of 90% to 95% quartz and 10% resin, colorant and other additives such as adjusting bonding and curing agent in vacuum at high temperature and high pressure. stone. However, at present, there are often hidden dangers to the health of people who use and contact them because of the pollution and bacteria on the surface of artificial stone products. There is an increasingly strong demand for antibacterial material products. Commonly used antibacterial agents are inorganic antibacterial agents, organic antibacterial agents, composite antibacterial agents, etc.; and in the preparation process of artificial quartz stone, the prior art uses unsaturated polyester resin and inorgan...

However, at present, there are often hidden dangers to the health of people who use and contact them because of the pollution and bacteria on the surface of artificial stone products. There is an increasingly strong demand for antibacterial material products

Commonly used antibacterial agents are inorganic antibacterial agents, organic antibacterial agents, composite antibacterial agents, etc.; and in the preparation process of artificial quartz stone, the prior art uses unsaturated polyester resin and inorganic antibacterial agents, and the disadvantages are that It is easy to vulcanize or oxidize, and has poor light stability. Adding it to the artificial quartz stone system will cause the fatal defect of discoloration of the product, and the cost of inorganic antibacterial agents is very high; although organic antibacterial agents have the advantages of fast speed, convenient processing, and clear antibacterial spectrum, etc., However, due to its poor stability, fast volatilization, short action time, difficult to combine, poor compatibility with the matrix and unsafe exudate, it is difficult to effectively apply it to the preparation process of artificial quartz stone
