Special plastic addition agent

Abstract

The invention discloses a special plastic addition agent. The addition agent is prepared from the following ingredients in parts by weight: 3.4-3.6 parts of modified calcium carbonate, 0.9-1.1 parts of organic stibium, 0.2-0.4 part of catalyst tetrabutyl titanate, 0.9-1.2 parts of active carbon, 10-12 parts of glass fiber and 0.5-1.5 parts of polyethylene wax. The special plastic addition agent provided by the invention can bring a better effect on production stability and production rate of plastics, and improves the degree of shock, rigidity and heat resistance of the plastics.

Description

technical field [0001] The invention relates to the field of plastics, in particular to a special plastic additive. Background technique [0002] The overall level of my country's plastic additives lags behind industrially developed countries by at least ten years or even more than 20 years, especially high-efficiency and high-performance additives, which seriously restrict the development of my country's plastics industry. Most of the manufacturers of plastic additives in my country are small workshop enterprises with small scale, backward production equipment and technology. Most of their products are general-purpose low-end products with unstable product quality and single variety. The research and development of plastic additives is still mainly based on the imitation of mature foreign products. [0003] A special plastic additive disclosed by the invention is characterized in that it consists of the following components by weight: 3.4-3.6 parts of modified calcium carb...
