Abstract

The invention provides a preparation process for quartz stone with long-acting organic antibacterial performance. The preparation process comprises the following steps: (1) weighing components according to a formula; (2) heating unsaturated polyester resin to 30 to 50 DEG C, adding a coupling agent and an organic antibacterial agent, and carrying out high-speed stirring for polymerization so as toform an prefabricated solution of organic polymer antibacterial resin; (3) adding a curing agent and a pigment and filler, carrying out mixing, adding the obtained mixture into a beater and carryingout grinding so as to form an organic polymer antibacterial adhesive; (4) dumping quartz powder, quartz sand and modified organic silicon resin into a hopper, carrying out stirring at a low speed andthen adding the organic polymer antibacterial adhesive so as to form a prefabricated material of quartz stone; and (5) subjecting the prefabricated material of quartz stone to tiling, compaction and curing so as to obtain the quartz stone with long-acting organic antibacterial performance. The preparation process for the quartz stone with long-acting organic antibacterial performance employs a manner of prefabrication of the organic polymer antibacterial adhesive to give better play to the antibacterial performance of the organic antibacterial agent, so the prepared quartz stone has more obvious and long-acting organic antibacterial performance. The preparation process is simple and convenient.

Description

Technical field [0001] The invention relates to the technical field of artificial quartz stone plates, in particular to a preparation process of 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%-95% quartz and 10% resin, pigments and other additives such as adjusting bonding and curing agents under vacuum, high temperature and high pressure. stone. However, due to the contamination of the surface of artificial stone products and the growth of bacteria, there is a greater hidden danger to the health of people who use and contact them. Therefore, the research on the antibacterial and sterilization properties of artificial quartz stone has received extensive attention. The demand for antibacterial material products is growing. In the preparation process of artificial quartz stone, the commonly used antibacterial agents are inorganic antibacte...
