Abstract

The present invention belongs to the field high molecular material technology, and especially one improved thermoplastic elastomer material and its preparation. Into S.E.B.S body material PP, PE, PS,EVA and other plastic capable of being cross linked with the body material are added to improve the hardness, elongation strength, elongation are and other physical performance and to widen the application range.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an improved thermoplastic elastomer material and a preparation method thereof. technical background [0002] The usual thermoplastic elastomer S.E.B.S (English abbreviation of polystyrene (S)-polyethylene (E)-propylene (B)-polystyrene (S) polymer) has good performance and is widely used. However, its hardness, tensile strength, elongation, etc. are greatly limited, and it does not meet the needs of some specific performance requirements. Contents of the invention [0003] The purpose of the present invention is to propose an improved thermoplastic elastomer S.E.B.S material to change its hardness, tensile strength, elongation and other physical properties. [0004] The thermoplastic elastomer proposed by the present invention takes S.E.B.S as the main body and adds cross-linkable plastics (note: the plastics refer to all plastics except PVC series and PU ...
