Problems solved by technology

[0004] Mix graphene with resin to prepare graphene-resin mixed impregnation solution, which largely improves the defects of resin impregnation solution such as poor mechanical properties and poor water resistance, but graphene itself is easy to agglomerate, so mixing it with resin-based materials , it is prone to sedimentation, affecting its gluing effect, and graphene is expensive, simply using it as a modifier to modify the impregnated resin will easily cause waste of raw materials, increase the cost of resin preparation, and is not suitable for mass production

Abstract

The invention relates to a graphene / metal composite modified adhesive impregnated veneer and a preparation method thereof. The impregnated veneer is prepared by impregnating pretreated log veneer intoa modified adhesive by using a vacuum pressurizing method, wherein the modified adhesive is prepared from impregnating resin and an ammonium polyphosphate-organic bentonite / graphene-Cu composite nano-material; every 100 parts by weight of resin contains 3 to 8 parts by weight of the ammonium polyphosphate-organic bentonite / graphene-Cu composite nano-material; every 100 parts by weight of waterborne coating contains 3 to 8 parts by weight of the ammonium polyphosphate-organic bentonite / graphene-Cu composite nano-material. The impregnated veneer prepared by the preparation method has the advantages of high heat transfer efficiency, high heating speed and good dimensional stability; the aims of rapid heat transfer, energy saving and consumption reduction are achieved.
