Abstract

The invention belongs to the technical field of composite and discloses an epoxy resin enhanced rubber material as well as a preparation method and an application thereof. The rubber material is mainly prepared from raw materials in parts by weight as follows: 1-30 parts of epoxy resin, 0.1-15 parts of a curing agent, 1-20 parts of epoxy natural rubber and 50-98 parts of rubber. An epoxy resin enhanced rubber matrix is adopted, and the prepared rubber material has better comprehensive performance due to the rigid network of the epoxy resin, the network function of the epoxy resin and rubber and the compatibilization of a compatilizer. The mechanical property, the wear resistance and the insulating property of the rubber material are remarkably improved by the aid of the epoxy resin and the compatilizer.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and relates to an epoxy resin-reinforced rubber material and a preparation method thereof. The rubber material is used for preparing tire products, industrial and civil wear-resistant products, insulation products and the like. Background technique [0002] With the development of society and science and technology, people have higher and stricter requirements for the use of rubber. The traditional single rubber matrix modification and blending modification often cannot meet the increasingly high use requirements of today's rubber due to many factors such as raw material sources, synthesis technology, and production costs. [0003] In recent years, the preparation of rubber-plastic blended materials has become an important means of developing new materials in the field of rubber and plastics. Rubber-plastic blending is to mix rubber and plastic into a homogeneous polymer through spec...
