Problems solved by technology

Compared with single nitrile rubber, the tensile strength and tear resistance of blended rubber are improved, but the compression permanent deformation of blended rubber and plastic products is relatively large, which has become a technical bottleneck in the manufacture of rubber and plastic thermal insulation materials
By adding a large amount of phthalate plasticizers (DOP, DBP) to improve the resilience of rubber and plastic products, it is easy to lead to excessive VOC emissions, resulting in environmental impact

Abstract

The invention relates to the technical field of rubber, in particular to an environment-friendly rubber and plastic product and a preparation method thereof. The preparation raw materials at least comprise, by weight: 10-18 parts of nitrile rubber, 3-9 parts of polyvinyl chloride resin, 2-6 parts of protective wax, 1-6 parts of a filler, 4-5 parts of a flame retardant, 4-7 parts of a foaming agent, 0.2-0.5 part of an active agent, 1-5 parts of an accelerant, 0.1-0.4 part of a vulcanizing agent, 10-20 parts of chlorinated paraffin and 0.3-2 parts of a deodorant. The preparation raw materials are selected preferentially, the proportion of the components is controlled and a deodorant is added, so that the rubber and plastic product has the characteristics of excellent mechanical properties, aging resistance and water resistance, is environment-friendly and safe, and can effectively protect the environment.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a green and environment-friendly rubber and plastic product and a preparation method thereof. Background technique [0002] Nitrile rubber (NBR) has good tear resistance, low compression deformation, excellent wear resistance and oil resistance. Its biggest use is to produce oil-resistant hoses, flame-retardant conveyor belts and oil-resistant rubber gasket materials. Has been widely used in automotive, aerospace, oil field chemical and other fields. At present, blending and modifying nitrile rubber to find a new reinforcement system and vulcanization system has become an important way to optimize the performance of nitrile rubber. [0003] At present, using technologies such as dynamic vulcanization technology, nitrile rubber / polyvinyl chloride, nitrile rubber / polypropylene, nitrile rubber / ethylene propylene rubber, nitrile rubber / polystyrene, nitrile rubber / chlorosulfonated Po...
