Rubber-plastic ternary composite material applied to mechanical industry as well as preparation method and application thereof

Abstract

The invention discloses a rubber-plastic ternary composite material applied to mechanical industry as well as a preparation method and application thereof. The rubber-plastic ternary composite material at least comprises three materials including polyurethane rubber and nitrile rubber as well as polyvinyl chloride plastics, and is formed through mixing by a milling machine or a rubber open mill through an enclosed chamber, wherein the composition and proportion of the three materials including polyurethane rubber and nitrile rubber as well as polyvinyl chloride plastics are as follows: 100 parts of polyurethane rubber, 50-70 parts of nitrile rubber and 15-25 parts of polyvinyl chloride plastics. The rubber-plastic ternary composite material provided by the invention is prepared from the three materials according to a certain proportion, the advantages of the three materials can be integrated effectively, the three materials are supplied mutually, and the comprehensive performances of the material are improved effectively.

Description

technical field [0001] The invention relates to a production method and application of a rubber and plastic material, in particular to a new rubber and plastic material used in the machinery industry and its production method and application. Background technique [0002] Since the development of polyurethane rubber (PUR) in the 1950s, due to its excellent performance, the output of polyurethane has increased, and it has also promoted the development of polyurethane elastomers. The Young's modulus of polyurethane elastomer is between rubber and plastic, with wear resistance, oil resistance, tear resistance, chemical corrosion resistance, radiation resistance, good adhesion with other materials, high elasticity and strong shock absorption ability, etc. Excellent performance, so it is widely used in many fields of national economy. [0003] Especially in the mechanical industry, especially in construction machinery, it is more widely used. In addition, it is also very popular...
