Abstract

The invention belongs to the chemical field and relates to a multifunctional assistant for plastic processing and a preparation method of the multifunctional assistant. The multifunctional assistant HGP-107 for the plastic processing comprises the following ingredients by weight part: 30-50 parts of beta-(3, 5-ditertbutyl-4-hydroxyl phenyl) octadecyl propionate (anti oxidizer 1076), 15-40 parts of tri (2, 4-ditertbutyl phenyl) phosphate (anti oxidizer 168), 30-50 parts of magnesium stearate and 1-10 parts of distillation stearin. In the multifunctional assistant, various kinds of assistants can be compounded with specific ratio, the compatibility of plastics is enhanced, the stability in the plastic processing procedure is enhanced, the oxidation resistance of plastic products is improved, and the remarkable antistatic and whitening effect and the like can be realized.

Description

technical field [0001] The invention belongs to the field of chemical industry, and relates to a multifunctional auxiliary agent for plastic processing and a preparation method thereof. Background technique [0002] The rapid development of my country's plastics industry has driven the continuous growth of the plastics additives industry. At present, the annual output of plastic additives in my country is nearly 1 million tons, and the actual annual consumption exceeds 1.3 million tons, of which the annual import volume is about 300,000 tons. It is expected that in the next 10 years, the average annual growth rate of plastic additives demand in my country will reach 10%, and it will become the world's largest plastic additives market. With the growth of the plastic product market, the requirements for plastic additives are also constantly increasing, which makes it show a new development trend in terms of variety, quality, technical content, and application fields. The thre...
