Abstract

The invention discloses a thermoplastic elastomer composition which is plasticated by the following main components by weight: 100 parts of polyurethane thermoplastic elastomers, 30-150 parts of polyvinyl chloride thermoplastic elastomers, 25-50 parts of styrene elastomers, 0-30 parts of blend and 4-8 parts of auxiliaries, wherein the auxiliary is any one or more of a composite rare-earth stabilizer, zinc stearate, calcium stearate, stearic acid or polyethylene wax; and the blend is butyronitrile N18. The invention selects the thermoplastic elastomers with similar polarity and complementary properties to be synthesized and used and selects compatilizers to organically combine several best molecules with different structures, so that the generated novel thermoplastic elastomer has superior performance and appropriate price, can meet the requirements of market products and has wide application range because the product has the technical advantages of excellent oil resistance, resistance to low temperature of minus 35 DEG C, acid-alkali resistance, aging resistance and lower proportion than the vulcanized products with the same price.

Description

technical field [0001] The invention relates to a plastic or rubber material, especially a thermoplastic elastomer and a production method thereof. Background technique [0002] Thermoplastic elastomer TPVC (polyvinyl chloride thermoplastic elastomer) has strong tensile strength, good weather resistance and relatively low price; thermoplastic elastomer TPU (thermoplastic polyurethane elastomer) has excellent low temperature resistance, superior High elastic elongation and very low permanent set, but poor weather resistance and relatively expensive. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a thermoplastic elastomer with good weather aging resistance, low temperature resistance and low cost. [0004] In order to solve the above-mentioned technical problems, the present invention is formed by plasticizing the following weight components: 100 parts of thermoplastic polyurethane elastomer (TPVC), 30-150 parts ...
