Abstract

The invention discloses fiber modified thermosetting rubber. The formula of the fiber modified thermosetting rubber is that 20 to 30 parts of vinyl phenyl silicon resin, 11 to 15 parts of melamine formaldehyde resin, 8 to 11 parts of methyl silicon hydroxy terminated silicone resin, 30 to 50 parts of solvents, 3 to 5 parts of chain transfer agents, 1 to 3 parts of catalysts, 2 to 4 parts of initiators, 12 to 18 parts of graphene fibers, 18 to 26 parts of ethanediamine, 3 to 5 parts of dispersants and 2 to 4 parts of thickeners. The invention further provides specific implementation materials and implementation manners. The fiber modified thermosetting rubber is simple in method, mild in process conditions, low in production cost, high in material structure stability, not destroyed by high temperature and improved stably in temperature resistance and toughness.

Description

Technical field [0001] The invention belongs to the technical field of rubber materials, and specifically relates to a fiber-modified thermosetting rubber. Background technique [0002] Thermosetting rubber is made of thermosetting resin as the main component, combined with various necessary additives to form a rubber product through a crosslinking curing process. In the early stage of the manufacturing or molding process, it is liquid. After solidification, it is insoluble and infusible, and cannot be melted or softened again. Common thermosetting plastics include phenolic plastics, epoxy plastics, amino plastics, unsaturated polyesters, and alkyd plastics. However, the brittleness and toughness of thermosetting rubber materials are still slightly insufficient and cannot meet the actual needs of use. In response to this problem, further improvements and improvements are needed. Summary of the invention [0003] The purpose of the present invention is to provide a fiber-modifie...
