Abstract

The invention discloses a low-temperature sintered energy-absorption buffering material. The low-temperature sintered energy-absorption buffering material is prepared from, by weight, 5-15 parts of polyurethane, 10-15 parts of polycarbonate, 5-10 parts of polyvinyl acetate, 2-5 parts of fluoro-siloxane resin, 7-12 parts of urea, 1-4 parts of dibutyl phthalate, 10-15 parts of aluminum alloy, 5-10 parts of aluminum powder, 5-12 parts of nickel oxide, 4-6 parts of magnesium alloy, 1-4 parts of 2-thiol benzimidazole, 2-5 parts of 2,6-ditert-butyl-4-methylphenol, 5-8 parts of methylparaben, 5-10 parts of methyl vinyl ether, 3-6 parts of an antioxidant and 5-10 parts of a heat stabilizer. The prepared low-temperature sintered energy-absorption buffering material is good in energy absorption performance, excellent in buffering and damping effect and stable in overall performance. Meanwhile, the invention discloses a corresponding preparation method.

Description

technical field [0001] The invention relates to the technical field of metal materials, in particular to a low-temperature sintered energy-absorbing buffer material and a preparation method thereof. Background technique [0002] There are a large number of porous materials in nature, and they have attracted the exploration of many scientists because of their excellent mechanical properties and various application functions. Thus, artificial porous materials came into being. Porous materials are generally divided into honeycomb materials and foam materials. The metal foam material is a kind of porous metal material, and its development has a history of several decades. Metal foam material, as a new type of engineering material, has its superior performance and wide application space. The metal foam material has high specific strength and high specific stiffness, and has good functions of sound absorption, noise reduction, energy absorption, and shock absorption. However, ...
