Abstract

The invention discloses a self-repairing rubber material, which is characterized by being prepared from the following components in parts by weight: 40 to 50 parts of epoxidized natural rubber, 30 to 40 parts of methyl vinyl silicone rubber, 5-10 parts of benzophenone-4,4'-dicarboxylic acid/amino-terminated polyurethane polycondensate, 8-12 parts of a hyperbranched secondary thiol compound, 2-4 parts of hyperbranched polyamidoamine, 2-5 parts of pig hair fiber, 15-25 parts of an inorganic filler, 2-3 parts of a coupling agent, 1-3 parts of a vulcanizing agent and 1-2 parts of a photoinitiator. The invention also provides a preparation method of the self-repairing rubber material. The self-repairing rubber material provided by the invention is better in comprehensive performance and performance stability, better in self-repairing effect and more excellent in mechanical property, temperature resistance, impact resistance and aging resistance.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a self-repairing rubber material and a preparation method thereof. Background technique [0002] In recent years, with the development of science and technology and the improvement of people's living standards, the properties of rubber materials have been continuously improved, and they have been more and more widely used in various fields of people's lives, and have become an indispensable part of people's daily life. However, rubber material products are inevitably subjected to external stimuli such as thermal, mechanical, chemical and ultraviolet radiation during their molding process and subsequent use, which will cause local damage or microcracks inside the material. These local damage or microcracks Cracks are extremely difficult to detect and repair, and will lead to a decrease in the mechanical properties of the material, which may affect the use of the material,...
