Abstract

The invention discloses a method for preparing thermoplastic resin, which comprises the following steps of: mixing acrylate rubber and chlorinated polyethylene rubber in a weight ratio of 9:1 to 3:7, adding hard monomer, wherein the ratio of the weight of the hard monomer to the total weight of the acrylate rubber and the chlorinated polyethylene rubber is 8:2 to 5:5; and polymerizing the mixture in a polymerization way of interpenetrating polymer networks to obtain the thermoplastic resin. The method bonds two kinds of colloidal particles during polymerization according to properties of two kinds of rubber particles ASA and ACS and obtains rubber with different particle sizes of colloidal particles and different molecular conformations through emulsion polymerization or suspension polymerization so as to obtain products with optimal cost performance.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a preparation method of thermoplastic resin. Background technique [0002] At present, there are endless new materials in the world, especially ABS, ASA and ACS, among which ABS is acrylonitrile / butadiene / styrene terpolymer, and ASA is acrylonitrile / acrylate rubber / styrene terpolymer ACS is a copolymer formed by grafting acrylonitrile and styrene onto the main chain of chlorinated polyethylene. And ASA and ACS have a great tendency to replace ABS. But the latter two have their own advantages and disadvantages. ACS resin contains chlorinated polyethylene, and chlorinated polyethylene itself has properties such as weather resistance, aging resistance and flame retardancy. Therefore, ACS resin not only has the excellent comprehensive properties of ABS resin, but also has excellent weather resistance and aging resistance. And the inherent flame retardancy and antistatic properties...
