Abstract

The invention discloses a preparation method of polypropylene fiber reinforced quartz synthetic stone plate. Polypropylene fiber: flexible unsaturated polyester resin: whisker silicon: silicon powder: ordinary quartz powder: color paste: auxiliary filler: nano-modified auxiliary agent: coupling agent: plasticizer: high temperature curing agent (mass ratio) =0.15~0.3:6~20:2~10:2~10:25~85:0.05~2:2~40:0.2~1:0.05~0.3:0.1~0.5:0.05~0.3, the polypropylene fiber, Flexible unsaturated polyester resin, plasticizer, color paste and high-temperature curing agent are stirred to obtain a mixed resin; whisker silicon, silicon micropowder, ordinary quartz powder and auxiliary filler are stirred and mixed, and nano-modified additives and coupling agents are added After high-speed stirring, modifying and dispersing, add the mixed resin, stir the blended material, import it into the plate-making mold, and after high-temperature curing and setting, it is water-milled and polished to obtain the polypropylene fiber-reinforced quartz synthetic stone plate.

Description

technical field [0001] The invention belongs to the technical field of artificial stone preparation, in particular to a preparation method of polypropylene fiber reinforced quartz synthetic stone plate. Background technique [0002] In China's rapidly developing home furnishing industry, artificial stone, as a new type of material, is widely used in the entire industry in addition to being used as a supporting product in the cabinet industry. Experts said that artificial stone is an important application field of unsaturated polyester resin. As a new type of artificial stone, quartz synthetic stone is widely used in cabinet countertops, bathroom countertops, dining table countertops, hospital countertops and laboratory countertops. [0003] However, ordinary quartz synthetic stone is composed of ordinary unsaturated polyester resin and quartz powder. It is a brittle polymer material and is easy to crack like ordinary glass. According to current market research, the cracking...
