Abstract

The present invention relates to the preparation method for a maleimide heat-resistant resin emulsion. Maleimide monomer, aryl vinyl monomer, nitrile group - ethylene monomer, oil-soluble thermal decomposition initiator and other agents are added into a mixing trough, and are mixed and stirred to form homogeneous monomer mixed solution (a); Then emulsifier and other agents are added into a reactor, and is stirred; then (a) is added to the reactor for emulsification so as to generate monomer emulsion (b); then desalination water and (b) are added to the reactor for polymerization reaction at the temperature of 60 DEG C to 90 DEG C; after the process, heat-resistant resin emulsion (c) is obtained. The anti-heat flame-retardant resin emulsion can be widely used in the improvement of anti-heat and flame-retardant effectiveness of ABS, PC, PBT and other materials. When used alone, the anti-heat flame-retardant resin emulsion can also be used in the anti-heat and flame-retardant componentsof automobiles and domestic appliances.

Description

technical field

[0001] The invention relates to a preparation method of a polymer emulsion, in particular to a preparation method of a maleimide heat-resistant resin emulsion. Background technique

[0002] Free radical copolymers of maleimide monomers have attracted extensive attention because of their molecular chains containing a planar five-membered ring structure, which can effectively inhibit chain rotation and thus have high structural rigidity and thermal stability. Among them, there are many studies on the copolymers of maleimide monomers and aryl vinyl monomers.

[0003] The preparation of ultra-high heat-resistant ABS resin includes alloy method and copolymerization modification method, among which copolymerization modification method is a better technical route. The alloy method mainly refers to the PC / ABS alloy. The copolymerization modification method is mainly composed of two parts of technology, one part is the maleimide monomer of maleimide (IMID) and aryl ...
