Description
Technical field
The present invention relates to a kind of composite rubber-plastic material and preparation method thereof, especially relate to high-performance composite rubber-plastic material and preparation method thereof for a kind of automatic foot-mat.
Background technology
Along with automobile and automobile consumption become universal, in all Automobile Products, have a kind to become indispensable---automatic foot-mat, the raising of people's living standard, also foot pad has been proposed to better requirement, comfortable, attractive in appearance, environmental protection, bear dirty, easy to clean, the fire-retardant focus that has become foot pad industry research.
Traditional automatic foot-mat greatly mainly with polyvinyl chloride (PVC) or rubber as material of main part, raising along with performance requriements, also developed and take the automatic foot-mat that elastomerics is material of main part, in recent years, nano level filler (calcium carbonate, carbon black, layered silicate etc.) also start application, although the change by formula has improved mechanical property, but cannot be from improving in essence the inherent defect of PVC or rubber automobile foot pad, (for example PVC automatic foot-mat easily slides, rubber mat smell is large etc.) therefore, originate in supporting foot pad performance and still have larger gap with European and American developed countries automobiles, therefore, the urgently appearance of the new formula of automatic foot-mat, promote its over-all properties, obtain new autonomous knowledge-product, the performance of catching up with and surpassing same kind of products at abroad.The bad major cause of automatic foot-mat over-all properties is at present: one, PVC material rebound resilience is poor, and elastomeric material smell is large, need to have the appearance of the novel material that has bi-material character concurrently; Two, the cold tolerance of common foot pad is poor, in the time of general 10 ℃, will produce be full of cracks, urgently the exploitation of cold tolerance elite clone; Three, the material microcosmic blend of common foot pad is even not, and intensity is relatively low.The compound high-toughness material of polyvinyl chloride, Chlorinated Polypropylene III, styrene-butadiene-styrene block copolymer combination of two that had more scholar's research in similar research, obtain certain effect, but still failed to significantly improve mechanics, the weather resistance of matrix material.Isoprene is the principal monomer of natural rubber, therefore styrene isoprene styrene block copolymer (SIS) has had the character of natural rubber concurrently, styrene block part also provide good mechanical property and with plastic material good mixing type, having realized rubber and plastic performance merges, therefore, this patent adopts the product of the application's Patent exploitation, to carrying, do composite property, significant to having further developing of independent intellectual property right, the enhancing competitiveness of product in market and propelling vehicle articles for use and product of rubber and plastic industry, market outlook are very wide.
Summary of the invention
Technical problem to be solved by this invention is to provide matrix material and preparation method and the application that a kind of high-performance rubber and plastic automatic foot-mat is used.
