Problems solved by technology

Nowadays, the key point of preparing modified plastics is to improve the compatibility of plastic additives. Generally, the actual production is direct additive blending, but this treatment also has the disadvantages of uneven distribution and single selectivity, which will cause the produced Modified plastics are unstable, and this method mainly depends on the functionality and stability of additives. If the composition of additives is stable, a large part of the modification process of modified plastics will be omitted in the case of direct blending. , so as to achieve a good cost reduction effect

Abstract

The invention provides a modified plastic additive and a preparation method thereof. The modified plastic additive is prepared from the following components: a thermoplastic elastomer, alumina fiber,magnesium oxide powder, tourmaline powder, titanium dioxide, a compound auxiliary agent, a modified treatment liquid, a coupling agent, an antioxidant and a dispersant. The additive prepared by usingthe preparation method provided by the invention has good compatibility with main plastic, integrates the effects of increasing toughness and whiteness, resisting bacteria and protecting the environment, and can effectively modify the main plastic to enable the main plastic to obtain the above-mentioned effects; meanwhile, the preparation method provided by the invention is simple, has low cost and is applicable to large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of modified plastics, and in particular relates to a modified plastic additive and a preparation method thereof. Background technique [0002] Modified plastics are intermediate products in the petrochemical industry chain. It is a new type of plastic product processed on the basis of general-purpose plastics and engineering plastics through filling, blending, and reinforcement. It is mainly processed from the five major general-purpose plastics and the five major engineering plastics as the plastic matrix, and has the characteristics of flame retardancy, impact resistance, high toughness, and easy processing. The current overall development level of the modified plastics industry is relatively low, and the production scale of enterprises in the industry is generally small. The market conditions of the products also show the characteristics of many primary products, unstable quality of intermediate products,...
