Problems solved by technology

[0002] Polyolefin plastic is a general-purpose plastic, because of its relatively simple synthesis process, low price, excellent performance, and wide application range; styrene-based resin is an engineering plastic with excellent performance, and the typical product is acrylonitrile-butadiene-styrene three Meta-copolymer, this product has excellent chemical resistance, formability, high and low temperature toughness, but its synthesis process is complicated, and its price is more expensive than polyolefin, which limits its use
In order to better integrate the advantages and properties of the two materials, many scholars have studied the alloy materials of the two products. However, it is well known that polyolefins and styrene-based resins have poor compatibility. If the two are simply melted and mixed, the obtained The product will delaminate to form two phases, and the material performance is extremely poor
In the Chinese patent that application number is 200510023968.7, PP (polypropylene) and ABS (acrylonitrile-styrene-butadiene copolymer) nano-filler alloy and its preparation method obtain a kind of PP and ABS nano-filler alloy, but the Affected by the formula and processing technology design in the invention, the ratio of the two main ingredients is in a relatively narrow range. In the actual application process, the scope of use has great limitations

Abstract

Belonging to the technical field of high polymer materials, the invention relates to a polyolefin / styrene based resin composition and a preparation method thereof. The composition is prepared from the following components by weight part: 100-800 parts of polyolefin; 100-800 parts of styrene based resin; 30-100 parts of a compatilizer; 30-200 parts of a toughening agent; 5-30 parts of a reinforcing agent; 3-10 parts of an antioxidant aid; and 2-5 parts of a processing aid. The polyolefin / styrene based resin composition prepared by the invention has stable mechanical properties. Compared with styrene based resin, the composition maintains comparable properties, and has an obvious price advantage, can partially or completely replace styrene based resin, and the economic benefits are significant. The polyolefin / styrene based resin composition provided in the invention is prepared by a twin-screw extrusion technology. Lateral forced feeding is preferably adopted in the production process, and the reinforcing agent can be dispersed better, so that the product can have excellent comprehensive properties.
