Embodiment 1
[0034] An anti-fouling and heat-dissipating composite board mainly includes, by weight, 70 parts of modified straw, 6 parts of polypropylene microporous membrane, 60 parts of carbon dioxide, 50 parts of copper ion solution, 25 parts of dopamine and 40 parts of isocyanate glue.
[0035] A method for preparing an antifouling and heat dissipation composite board, the preparation method of the antifouling and heat dissipation composite board mainly includes the following preparation steps:
[0036] (1) Mix the pretreated straw and water in a beaker at a mass ratio of 1:10, and add emulsifier OP-10 with 0.1 times the weight of the pretreated straw and glycidyl methacrylate with 6 times the weight of the pretreated straw into the beaker Esters and benzoyl peroxide of 0.15 times the mass of the pretreated straw were stirred and reacted for 1.5 h at a temperature of 65° C. and a rotating speed of 450 r / min, and then filtered to obtain a pre-modified straw blank. The pre-modified straw ...
