STYRENE-BASED RESIN BLEND COMPRISING PARTICLES HAVING A TRI-LAYER STRUCTURE AND THE PREPARATION METHOD THEREOF

摘要

The present invention relates to a styrene resin blend having three-layer-structured particles, a method for preparing same, and an application thereof. In parts by weight, 100 parts of a vinyl aromatic compound, 0.1 to 10 parts of an initiator, 2 to 10 parts of an emulsifier, 100 to 300 parts of deionized water, and 0.1 to 10 parts of a cross-linking agent are polymerized at a temperature between 50° C. to 85° C. to acquire a core seeded emulsion; 15 to 70 parts of the core seeded emulsion, 0.1 to 10 parts of the initiator, 2 to 10 parts of the emulsifier, 80 to 300 parts of deionized water, and 30 to 85 parts of butadiene or another rubber monomers are reacted to acquire a two-layer particle emulsion; 40 to 90 parts of the two-layer particle emulsion, 10 to 70 parts of monomers of the vinyl aromatic compound, 10 to 60 parts of monomers of a vinyl cyanide compound, 2 to 10 parts of the emulsifier, and 80 to 300 parts of deionized water are reacted to acquire the blend; the impact strength thereof reaches 300 J/m, and the tensile strength is 53 MPa.
