Problems solved by technology

After the resin and quartz are mixed evenly, during the curing process of the resin, the quartz of various particle sizes must be kept in suspension to avoid deposition and stratification. If the viscosity value of the selected unsaturated polyester resin is low, the quartz stone particles are easy to sink to form components layer state; if the viscosity value of the selected unsaturated polyester resin is too high, the ratio of resin to filler consumed in the production of quartz stone plates will increase, which will consume more resin and increase the cost

Description

Technical field[0001]The present invention belongs to the technical field of high molecular polyester materials, and in particular, a high tough polyester resin and a synthetic method thereof.Background technique[0002]With the improvement of people's living standards and the development of aesthetics, the decorative countertops are also gradually replaced by various colors of marble and artificial stone, but natural granites and marbles have a radioactive element. Micropores make it poorly polluting. Nowadays, people are more preferred in the decoration. Artificial stone is made of unsaturated polyester resin as a binder, equipped with a variety of natural stone powder, silica sand, glass powder and other inorganic powders and an appropriate amount of additives, color materials, and the like. They have natural stone unparalleled advantages in moisture-proof, antisocism, and planarity.[0003]The polyester resin is one of the basic raw materials of artificial quartzstones, and the bond...
