With the continuous growth of China's economic development and the substantial increase of per capita income, the real estate industry has also undergone explosive improvement. In addition, in order to better stimulate external demand, China's new infrastructure construction projects continued capital construction, resulting in a substantial increase in the requirements of plastic decorative building materials (plastic water pipes, wire pipes, plastic steel windows, plastic plates, plastic films, etc.). Plastic color masterbatch is an indispensable color paste commodity in the production and processing of contemporary plastic products. Titanium dioxide and lithopone, the key color pastes of plastic masterbatch, are developing rapidly. The demand of organic pigments for plastic masterbatch is increasing at a rate of more than 25% every year.

Lithopone, also known as lithopone, is a white crystalline powder, a mixture of zinc sulfide and barium sulfate, insoluble in water. Zinc sulfide and barium sulfate can fade into dark gray under ultraviolet irradiation, so the aging resistance and use performance are weak, but the paint adhesion and fineness are very good, only inferior to titanium dioxide. Because the price of lithopone in Langfang city is far less than that of titanium dioxide, lithopone is often used as a substitute for titanium dioxide and mixed with titanium dioxide to achieve excellent paint adhesion and fineness and reduce product cost.

Because of the poor aging resistance and processing characteristics of lithopone, in order to better improve the use of lithopone, it is necessary to carry out modified materials on its surface.

The common coloring methods of thermosetting plastics are as follows:

Color paste: natural resin and colorant (such as titanium dioxide, lithopone, etc.). It is mixed, pre molded and pelleted into colored plate plastics, and then added to the epoxy resin of rubber and plastic products used to produce plastic goods.

Powder coloring: powder Colorants (such as titanium dioxide, lithopone, etc.). After mixing with natural resin, it can be used to produce plastic products immediately.

Masterbatch coloring: now the application of common plastic coloring. Colorants (such as titanium dioxide, lithopone, etc.). In the medium, it is simply mixed with natural resin and then used to produce plastic goods.
