Abstract
The invention discloses a polyolefin composition, wherein the constituents comprises (by weight ratio): polyolefin resin 20-70%, mineral filler 15-50%, functionalized polystyrene resin 2-25%, coupling agent 0-0.5%, anti-oxidant 0.1-1%. The produced polyolefin composition has good rigidity and tenacity, thus can be used for substituting PS (polystyrene) material in manufacturing outer casings or bases of various household electrical appliances or automobile interior members.
Description
Technical field
The present invention relates to a kind of high-dimensional stability, high performance polyolefin compositions.
Background technology
Polypropylene is a kind of resin of high comprehensive performance, has good processibility, rigidity and toughness preferably.Polypropylene is a half hitch crystal formation resin, and the dimensional contraction rate is big, and the shrinking percentage of unmodified acrylic resin is 1.4-1.8%, and dimensional stability is bad when being used to make big parts.Usually improve polyacrylic dimensional stability and realize, but the adding of filler has sharply reduced the toughness of polypropylene material by adding filler.The present invention obtains a kind of low-down dimensional stability that has, and has rigidity and flexible polyolefin compositions concurrently.Said composition can replace materials such as ABS, HIPS to be used to make parts such as televisor surgery, base plate of air conditioner.
PL Xie Er has reported moisture chemical processing agent or the sizing agent that uses siliceous fiber and filler in Chinese patent " glass fibre sizing agent and sized glass fibre and polyolefin reinforcing articles " (1143943), contain the polymkeric substance that can form the compatible polyolefin film, functional organic silane and at least a stablizer are to make polyolefin reinforcing articles.Wherein sizing agent contains the partial ester of existing one or more branched carboxylic acids multipolymers.This technology can not improve the dimensional stability of strongthener.
Summary of the invention
