preparation example Construction

[0031] The preparation of the rubber-modified styrenic resin of the present invention may optionally add additives or other polymers to obtain the rubber-modified styrenic resin of the present invention. Among them, the additives are such as but not limited to antioxidants, plasticizers, processing aids, ultraviolet stabilizers, ultraviolet absorbers, fillers, strengthening agents, colorants, lubricants, antistatic agents, flame retardants, flame retardant aids , heat stabilizer, coupling agent, etc. The additive can be added during the above-mentioned polymerization reaction, after the polymerization reaction, and before coagulation, or the above-mentioned additive can be added during the process of extruding and kneading to prepare the rubber-modified styrene resin.

[0032]The antioxidants can be used alone or in combination, such as but not limited to phenolic antioxidants, thioether antioxidants, or phosphorus antioxidants. Preferably, based on 100 parts by weight of the...

Abstract

The present invention discloses a rubber-modified styrene-based resin, a process for producing the same, and a molded product prepared therefrom. The rubber-modified styrene-based resin comprising 72 to 88% by weight of a styrene-based copolymer and 12 to 28% by weight of rubber particles. The styrene-based copolymer comprises a first styrene-acrylonitrile copolymer and a second styrene-acrylonitrile copolymer, the weight average molecular weight of the first styrene-acrylonitrile copolymer is from 5 to 100,000, The weight average molecular weight of the second styrene-acrylonitrile copolymer is 1.4 to 3.5 with respect to the weight average molecular weight of the first styrene-acrylonitrile copolymer. The rubber-modified styrene-based resin of the present invention has a property of high fluidity and high impact resistance, and can maintain other physical properties while meeting the needs of the industry.

Description

technical field [0001] The invention relates to a rubber-modified styrene resin, and in particular to a rubber-modified styrene resin with good fluidity and impact resistance. Background technique [0002] Generally, plastic moldings used for electrical equipment and household goods contain mostly rubber-modified styrene-based resins, polycarbonate resins, and the like. Among them, the rubber-modified styrene resin, such as acrylonitrile-butadiene-styrene resin (Acrylonitrile-Butadiene-Styrene Resin, referred to as ABS) is widely used in electrical appliances, electronics and auto parts, mainly because of its It has good evaluation in terms of formability, physical properties and mechanical properties. [0003] However, with the continuous improvement of users' quality requirements, there is still a need to improve the impact strength of general rubber-modified styrene-based resins. Among them, the rubber-like graft copolymer is dispersed in the styrene-based copolymer to ...
