Preparation method of rubber and plastic filling agent

Abstract

The invention discloses a preparation method of a rubber and plastic filling agent. The preparation method comprises the steps of 1) refining coal dust; 2) configuring a modifier; and 3) preparing the rubber and plastic filling agent: mixing the refined coal dust and the modifier, stirring and drying to obtain the rubber and plastic filling agent. According to the filling agent prepared by the processes of mixing, drying and the like, the preparation process is simple, the operation is easy, the filling agent can replace carbon black in common industries, and is superior to common carbon black in the aspects of electrical property, impact property, processing property and the like.

Description

technical field

[0001] The invention relates to fillers for rubber reinforcing agents and plastic fillers, in particular to a preparation method for rubber and plastic fillers. Background technique

[0002] The rubber industry and the plastics industry play a pivotal role in national life. In recent years, in order to better promote the development of rubber and plastic industries, the reinforcement of rubber and the low-cost filling of plastics without affecting the performance of plastics have been receiving much attention. Therefore, the filler has attracted extensive attention from the rubber industry and the plastics industry. For rubber fillers, it can increase the tensile strength of rubber, improve the processing performance of rubber, and reduce product cost. Fillers in plastics can greatly reduce the cost of the product and improve the processing performance of the product. In addition, to a certain extent, it can improve the various properties of the plastic pro...
