Preparation method of fiber rubber type shock-absorbing material

Abstract

The invention discloses a preparation method of a fiber rubber type shock-absorbing material and belongs to the technical field of preparation of shock-absorbing materials. The preparation method comprises the following steps: firstly, mixing and grinding silicon carbide and silicon nitride to obtain mixed powder; then melting and spinning the mixed powder to obtain self-made mixed fibers. As in asystem, the self-made mixed fibers are connected through staggered base material molecular chains, the surface of the vegetable sponge is modified by means of an alkaline solution, so that cutin andwax coats on the surfaces of cell walls of the vegetable sponge are removed favorably, and the extent of crystallization and polymerization of cellulose is reduced. In addition, the modified vegetablesponge particles are carbonized to prepare self-made activated carbon. Once being impacted by an external force, segmental motions of a base material are constrained by means of the self-made activated carbon. By adding trimethylolpropane trimethacrylate continuously and carrying out high-temperature irradiation crosslinking modification, twining and interaction among the molecular chains of thebase material are improved, so that the base material has higher cell density and more uniform pore distribution, and therefore, the heat dissipating property of the shock-absorbing material is further improved. The material has a wide application prospect.

Description

technical field [0001] The invention discloses a preparation method of a fiber rubber type shock absorbing material, which belongs to the technical field of shock absorbing material preparation. Background technique [0002] With the rapid development of modern industry, vibration and noise have become serious problems in various fields, which will reduce the operating accuracy, affect product quality, shorten product life, make high-precision instruments not work normally, endanger safety, and make equipment or construction Early destruction of objects, environmental pollution and impact on human health. In order to prevent the noise and vibration produced by automobiles, home appliances and other vehicles and industrial machinery, in addition to reducing or eliminating the vibration of the vibration source, it is more practical to develop and utilize various shock-absorbing products, among which rubber shock-absorbing products are particularly important. Part. The elasti...
