Abstract

The invention belongs to the functional material field, and relates to a damping composite material and a preparation method. The material comprises the following composition: 2-4% of titanium dioxide, 0.8-1.1% of a catalyst nickel naphthenate-aluminium triisobutyl-boron trifluoride etherate, 0.8-1.1% of an antioxidant N-phenyl-beta-naphthylamines, 4-6% of zinc oxide, 2-5% of stearic acid, 1-3% of sulphur, 16-20% of ABS material slag complex, 1-3% of a promoter N-cyclohexyl-2- benzimidazole sulfenamide and the balance of butadiene rubber. In the preparation method, mass usage of precious material is not required, the raw material cost is reduced, waste material is employed as the raw material, the preparation technology is simple, and process is simple. The material enables sound absorption and damping vibration attenuation, energy can be effectively absorbed when the vibration is generated, the damping composite material can be used in the transportation, building and military fields, and has the effects of shock resistance, impact mitigation, heat insulation and sound insulation.

Description

technical field [0001] The invention belongs to the field of functional materials, and relates to a damping composite material and a preparation method thereof. Background technique [0002] CN201210364827.1 It relates to a damping and vibration-reduction composite material using textile waste rubber and a preparation method thereof. The components are textile waste rubber and seven-hole hollow polyester staple fiber SHPF, and the mass ratio is 100:15-25; the preparation method includes: ( 1) Add waste rubber powder to the roller of the plastic refining machine to make flakes; add seven-hole hollow polyester staple fiber and mix; after cooling the mixed material at room temperature, make mixed flakes for each use; (2) The above-mentioned mixed flakes are evenly spread in the inner cavity of the mold, and the upper and lower sides of the mold are clamped by steel plates; the steel plates are moved into the flat vulcanizer, unloaded, and pressurized; the steel plates are remo...
