Scratch-resistant thermoplastic elastomer and preparation method thereof

Abstract

The invention discloses a scratch-resistant thermoplastic elastomer and a preparation method thereof in the technical field of thermoplastic elastomers. The scratch-resistant thermoplastic elastomer comprises the following raw materials, by weight: 50-200 parts of hydrogenated styrene thermoplastic elastomers, 20-400 parts of a plasticizing system, 40-200 parts of plasticizing reinforced resin, 0-200 parts of a filling system, 0.2-2 part of an antioxidant, 0.2-40 part of a scratch-resistant agent and 0-30 parts of a coloring agent. The thermoplastic elastomer material prepared by processing the hydrogenated styrene thermoplastic elastomer, the plasticizing system, the plasticizing reinforced resin, the filling system, the antioxidant, the scratch-resistant agent and the coloring system according to a certain ratio has good surface scratch resistance, soft touch and good mechanical properties; and the phenomena of whitening and mark leaving caused by interface damage in the scraping process are avoided, and wide application prospects are achieved in the fields of daily supplies, office automation, automobile accessories, household appliances, electric tools and the like.

Description

technical field [0001] The invention relates to the technical field of thermoplastic elastomers, in particular to a scratch-resistant thermoplastic elastomer and a preparation method thereof. Background technique [0002] With the rapid development of thermoplastic elastomers in the fields of daily necessities, office automation, auto parts, household appliances and electric tools, more and more applications begin to pay attention to the good quality of products while satisfying the appearance, touch and mechanical properties of materials. Scratch resistance. At present, composite materials are widely used in automotive interior products. However, the toughness and scratch resistance of most composite materials are poor. In order to make thermoplastic elastomer materials better meet the application requirements of automotive interior and other fields, especially the requirements of high-end automotive interior product materials, there is an urgent need for thermoplastic ela...

AI Technical Summary

Problems solved by technology

[0003] At present, due to the interface between the filled inorganic component and the polymer matrix, the interface is the most easily damaged part of the two phases. When the content of the inorganic material exceeds a certain content, the material is prone to scratching and whitening, and the surface is easy to wear and leave marks Insufficient and poor appearance and other problems; in order to solve the problems of scratch whitening, easy wear and tear on the surface, etc., the prior art usually chooses to reduce the content of inorganic materials. When the amount is less than 10%, the scratch whitening is not obvious, But the cost is to sacrifice the cost performance of materials and a certain degree of market competition space.
