Abstract

The invention discloses a thermoplastic elastomer material and a preparation method thereof, and relates to the technical field of thermoplastic elastomers, the thermoplastic elastomer material comprises a main body, the outer surface of the upper end of the main body is provided with a flame retardant coating, the lower end of the main body is provided with an anti-static mechanism, and the lower end of the anti-static mechanism is provided with a protection device. Under the combined action of the colloid, the liquid flame retardant, the solid flame retardant, the accelerant and the styrene coating, the thermoplastic elastomer can have good flame retardance and elasticity, and the liquid flame retardant and the solid flame retardant are added to the surface of the elastomer material, so that the thermoplastic elastomer is not prone to spontaneous combustion; under the combined action of the carbon black coating, the chopped conductive fiber coating, the conductive mica powder coating, the thin film and the polyurethane coating, the antistatic capacity of the elastomer material can be improved, the arranged chopped conductive fiber coating contains carbon fibers and metal fibers, and the carbon fibers and the metal fibers have very low body resistance and are generally presented in a network line shape, so that the antistatic performance of the elastomer material is improved. Therefore, the current is not easy to pass through the elastomer material.

Description

technical field [0001] The invention relates to the technical field of thermoplastic elastomers, in particular to a thermoplastic elastomer material and a preparation method thereof. Background technique [0002] Thermoplastic elastomer, also known as artificial rubber or synthetic rubber. Its products not only have the excellent properties of high elasticity, aging resistance and oil resistance of traditional cross-linked vulcanized rubber, but also have the characteristics of convenient processing and wide processing methods of ordinary plastics. It can be produced by injection molding, extrusion, blow molding and other processing methods, and 100% of the corners of the nozzle can be directly used for secondary use after being crushed. It not only simplifies the processing process, but also reduces the processing cost. Therefore, the thermoplastic elastomer material has become the latest material to replace the traditional rubber. It is environmentally friendly, non-toxic...
