Waterproof shock-absorbing foaming composite material

Abstract

The invention discloses a waterproof shock-absorbing foaming composite material, and belongs to the technical field of resin foaming composite materials. The waterproof shock-absorbing foaming composite material is prepared by using the following steps: (1) acquisition of a primary mixture: adding, in parts by weight, 6-12 parts of a thermal conductive material to 40-100 parts of matrix resin withthe density shown in the description so as to obtain the primary mixture; (2) blending modified plasticizing and extrusion granulation of raw materials: adding, by parts by weight, 2-8 parts of a flame retardant, 6-10 parts of a softening plasticizer, 3-7 parts of a toughening agent, 1-4 parts of a coupling agent and 0.6-1.2 parts of an antioxidant to the primary mixture, performing blending modified plasticizing, and performing extrusion granulation so as to obtain first particles; (3) re-blending foaming: mixing, in parts by weight, 15-25 parts of sodium fatty alcohol polyoxyethylene ethersulfate with the first particles and 30-70 parts of one or more of the matrix resin, performing extrusion foaming so as to obtain a foamed material, and then compounding a semi-open pore foaming material layer and a moisture-proof film layer on the foamed material sequentially through glue so as to form the high-heat dissipation waterproof shock-absorbing material. The waterproof shock-absorbing foaming composite material has high thermal conductivity, waterproofness and shock absorption.

Description

technical field [0001] The invention belongs to the technical field of resin foam composite materials, and in particular relates to a waterproof and shock-absorbing foam composite material. Background technique [0002] In the prior art, epe, eva, ixpe, xpe, rubber foaming materials, etc. are commonly used as foaming materials. These products have the function of heat preservation and heat insulation, but their thermal conductivity is poor, which limits their application in many fields and consumes a lot of energy. [0003] CN101974208A (2011-2-16) discloses a resin composition with high thermal conductivity and a metal-clad plate with high thermal conductivity made using it. However, the heat dissipation of the material still needs to be improved. Contents of the invention [0004] The present invention aims at the state of the prior art, overcomes the above-mentioned defects, and provides a waterproof and shock-absorbing foam composite material. [0005] The present inv...
