Abstract

The invention provides an epoxidized natural rubber composite material with self-repair function and a preparation method thereof, belonging to the technical field of composite materials. The epoxidized natural rubber composite material described in the present invention contains 100 parts of epoxidized natural rubber matrix, 1-3 parts of dicumyl peroxide, 1-40 parts of polyurethane, 1-2 parts of anti-aging agent, and 0.5 parts of ultraviolet absorber. ‑1 part, the above-mentioned number of parts is the number of parts by mass. The invention synthesizes UPy grafted polyurethane first, and then reacts it with rubber molecular chains to prepare a composite material with self-repair function. The prepared composite material can realize self-repair under the condition of complete end fracture, and also has good The strength and stability are high, and the preparation method is simple and the cost is low.

Description

technical field

[0001] The invention belongs to the technical field of composite material preparation, and relates to an epoxidized natural rubber composite material with self-repair function and a preparation method thereof. Background technique

[0002] Rubber materials and polyurethane materials are traditional polymer materials widely used in daily life. In recent years, the research and application of reinforcing traditional polymers have gradually reached the bottleneck. With the rapid rise of artificial intelligence, the performance of polymer materials The requirements are not limited to the improvement of mechanical properties, but also the functional and intelligent performance of polymer materials. Most of today's frontier research on polymers is based on molecular design and synthesis to realize the functionalization of polymer materials, such as research on electronic skin and soft sensors, which consumes too many petrochemical products. Therefore, it is necess...
