Problems solved by technology

[0003] In the prior art, thermoplastic elastomers have unsatisfactory surface effects due to the limitation of their own material properties. Therefore, most thermoplastic elastomer products need to be painted before the finished product. The painting process has certain risks, and storage is inconvenient. The production cost is high and environmental protection Low performance and low economy, the product itself is not wear-resistant and easy to scratch

Abstract

The invention discloses a formula, production process and application method of a thermoplastic elastomer surface treatment-free plasticizing material. According to the formula, production process andapplication method of the invention, a plurality of materials such as modified polypropylene, polyurethane, nitrile butadiene rubber, a styrene block copolymer, maleic anhydride, an antioxidant and the like are used as raw materials; and the raw materials are uniformly mixed, copolymerization granulation is performed, so that the thermoplastic elastomer surface treatment-free plasticizing material which is stable in property and can be packaged, stored and transported is obtained. Experiments show that various properties of a thermoplastic elastomer can be comprehensively improved only by doping a small amount of thermoplastic elastomer raw material; and therefore, the surface performance of a thermoplastic elastomer molded product is effectively improved, the effects of smoothness, abrasion resistance and scratch resistance are achieved, surface treatment procedures such as paint spraying are omitted, and safety, stability, economy and environmental protection are achieved. The formula, production process and application method provided by the technical schemes are complete and clear, easy to implement and popularize, and have high remarkable advancement and extremely high industrial value and bright application prospects.

Description

technical field [0001] The invention relates to the technical field of thermoplastic elastomers, in particular to a formula, production process and application method of a thermoplastic elastomer surface treatment-free plasticizing material. Background technique [0002] Thermoplastic elastomer (TPE), also known as artificial rubber (TPR), is a new type of polymer material between rubber and resin. It can not only replace part of rubber, but also modify plastic. The dual properties and broad characteristics of rubber and plastics possessed by thermoplastic elastomers make them widely used in the rubber industry to manufacture daily-use products such as rubber shoes, rubber cloths, rubber hoses, tapes, rubber strips, rubber plates, rubber parts and adhesives, etc. Various industrial supplies. At the same time, thermoplastic elastomers can also be used in large quantities instead of rubber in general thermoplastic resins such as PVC, PE, PP, PS, and even in the modification o...
