s3, treating the surface of the board core by adopting a shaving board, removing dust and sundries, uniformly spraying the bonding layer bean gum to the surface of the board core by using a glue sprayer, wherein the glue spraying amount is 40 g/square meter, carrying out first hot pressing at 180 ℃ and under the condition of 2.5MPa, and the hot pressing time is 200S;
s4, uniformly paving carbon fiber cloth on the board after the first hot pressing, uniformly spraying the bean gum of the reinforcing layer on the carbon fiber cloth and the board by using a glue spraying machine, wherein the glue spraying amount is 60 g/square meter, and then carrying out pre-hot pressing at 220 ℃ and under the condition of 2.5MPa for 40S;
s5, paving the melamine impregnated paper on the board after the pre-hot pressing, and then carrying out the secondary hot pressing at 220 ℃ under the condition of 2.5MPa for 300S.
According to the invention, the carbon fiber cloth is used for reinforcing the plate, and the modified soybean glue is used for bonding and coating the plate, so that the overall physical strength of the plate is effectively enhanced, the bonding strength of the soybean glue on the bonding layer is strong, the bonding effect of the plate core and the carbon fiber cloth can be enhanced, and the tensile strength and the compressive strength of the plate are improved; the short carbon fiber strengthens the physical characteristic of the reinforcing layer, the reinforcing layer after hot-pressing and solidifying has high strength and good toughness, and can effectively prevent the edges and corners of the plate from falling off, falling off and the like; meanwhile, after the reinforcing layer bean gum is compounded with the chopped carbon fibers, the corrosion of moths can be effectively prevented, and the insect prevention effect is good.
While specific embodiments of, and examples for, the invention are described in detail, these are by way of illustration only, and any equivalent modifications or alterations to this invention would be apparent to those skilled in the art and are intended to be included within the scope of this invention. Accordingly, it is intended that all equivalent alterations and modifications be included within the scope of the invention, without departing from the spirit and scope of the invention.
