Problems solved by technology

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

Embodiment

[0016] Embodiment-a kind of preparation method of organic long-acting antibacterial quartz stone, comprises the steps:

[0017] (1) After heating the unsaturated polyester resin to 40°C, add γ-methacryloxypropyltrimethoxysilane and organic antibacterial agent, mix them together, enter the high-speed disperser and stir at high speed for 15 minutes, and then polymerize to form Organic macromolecule antibacterial resin prefabricated solution is ready for use;

[0018] (2) Add tert-butyl peroxide 2-ethylhexanoate, pigments and fillers to the organic polymer antibacterial resin prefabricated solution, mix them into a beater, and grind them into a colored organic polymer antibacterial adhesive;

[0019] (3) Pour the quartz powder, quartz sand and modified silicone resin into the trough, stir and mix at a slow speed, then add the organic polymer antibacterial adhesive, and stir evenly in the trough at a slow speed to form a quartz stone prefabricated material;

[0020] (4) Spread th...

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...
