Thermoplastic elastomer composition for sports floor and preparation method thereof

Abstract

The invention provides a thermoplastic elastomer composition for sports floors and a preparation method of the thermoplastic elastomer composition. The thermoplastic elastomer composition for the sports floor comprises the following raw materials in parts by weight: 90-110 parts of butadiene rubber powder, 60-80 parts of natural rubber powder, 40-60 parts of polyvinyl chloride resin, 40-50 parts of epoxy resin, 60-70 parts of polystyrene, 20-30 parts of talcum powder, 20-30 parts of white carbon black, 40-60 parts of benzenediol, 40-60 parts of benzene, 20-30 parts of a vulcanizing activator, 15-25 parts of a vulcanization accelerator, 15-25 parts of a rubber additive, 10-20 parts of a silane coupling agent, 10-20 parts of a stabilizer, 10-20 parts of a plasticizer, 15-25 parts of a cross-linking agent and 15-25 parts of a vulcanizing agent. According to the present invention, the obtained thermoplastic elastomer composition has characteristics of good elasticity, good crack resistance, good shock absorption, good elasticity, good oil control property, good shrinkage resistance and the like, and has a long service life.

Description

technical field [0001] The invention relates to the technical field of sports field floors, in particular to a thermoplastic elastomer composition for sports floors and a preparation method thereof. Background technique [0002] Sports flooring is a floor specially developed for sports venues using polyvinyl chloride materials. Specifically, it uses polyvinyl chloride and its copolymer resin as the main raw material, adding fillers, plasticizers, stabilizers, colorants and other auxiliary materials. A floor covering produced by coating or calendering, extrusion or extrusion on a sheet-like continuous substrate. [0003] A thermoplastic elastomer composition and its preparation method and application are disclosed in the Chinese invention patent with the publication number CN107974024B. The composition includes the following raw material components in parts by weight: SEPS and / or SEEPS, 75-120 parts; ethylene - Octene block copolymer olefin, 65-102 parts; Paraffin oil, 80-15...

AI Technical Summary

Problems solved by technology

[0004] However, the inventor believes that the sports field floor prepared by the above thermoplastic elastomer composition has defects such as poor deformation resistance and poor cracking resistance, which greatly shortens the service life of the sports field floor.
