Abstract

The invention provides a high-melt-strength styrenic resin composition, which comprises the following components proportioned in certain parts by weight: styrenic resin or styrenic alloy, tackifier, antioxidant, lubricating agent agent. Compared with the prior art, the present invention has the following beneficial effects: 1, as the random copolymer of tackifier in the present invention, has thermodynamic compatibility with styrene resin and its alloy, phase separation does not take place, mechanical Excellent performance; 2. The molecular weight of the random copolymer used as a tackifier in the present invention is moderate, and it is easier to plasticize than resins such as rubber powder, high molecular weight SAN powder, heat-resistant powder, etc., so it has better processability, thickness Uniform, low shrinkage, not easy to produce surface defects.

Description

technical field [0001] The invention relates to a high-melt strength styrene resin composition and a preparation method thereof, belonging to the field of polymer materials. Background technique [0002] ABS resin is a resin with excellent performance, which has excellent impact resistance, heat resistance, dimensional stability and excellent dyeing performance. It has been widely used in the fields of electronics, home appliances, automobiles, etc. processing technology. The most common processing method is injection molding, but there are also processes such as extrusion and blow molding. For example, automobile tail fins and spoilers are usually prepared by blow molding, while refrigerator linings are generally prepared by blister technology. In processes such as blow molding, if the melt strength of the material is insufficient, it is easy to cause the embryo body to sag and collapse; when blistering, a series of problems such as local overthinness and even rupture may...
