AI Technical Summary

Problems solved by technology

However, due to the interface between the 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 20%, the material is prone to scratches and whitening, and the surface is easy to wear and tear. Problems such as poor appearance
In order to solve the problems of scratch whitening and easy wear of the surface, the method in the prior art is 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 the material

Abstract

The invention relates to a scratch-resistant thermoplastic elastomer material and a preparation method thereof. The thermoplastic elastomer material is prepared from raw materials in percentage by mass as follows: 20%-30% of styrene-ethylene / butylene-styrene triblock copolymers, 10%-20% of polypropylene, 20%-40% of softening oil, 20%-30% of inorganic materials, 0.5%-2% of a glass fiber exposure preventing modifier, 1%-3% of petroleum resin, 1%-2% of a flowing synergist, 0.2%-2% of high-molecular-weight silane and 0.1%-0.2% of an antioxidant. The provided thermoplastic elastomer material has better scratch resistance, the blushing phenomenon caused due to interface damage in the scratching process is avoided, and the scratch-resistant thermoplastic elastomer material has broad application prospect in the fields of daily supplies, office automation, automobile spare parts, household appliances, electric tools and the like.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a scratch-resistant thermoplastic elastomer material and a preparation method thereof. Background technique [0002] Thermoplastic elastomer (TPE) has the elasticity of thermosetting rubber and the repeated processing characteristics of ordinary thermoplastics. It is widely used in office supplies, household appliances, and daily necessities due to its high cost performance, recyclable scrap, reusable, and low environmental pollution. , medical and health, transportation and electric tools and other fields. [0003] In the practical application of thermoplastic elastomers, in order to reduce costs and improve the market competitiveness of products, it is generally necessary to add inorganic materials such as calcium carbonate, talcum powder and barium sulfate to fill thermoplastic elastomers. The addition of inorganic materials can not only reduce the cost, but also increase the...
