The purpose of the invention can be realized by the following technical scheme:
a preparation process of plywood with waterproof and flame-retardant properties comprises the following specific preparation processes:
firstly, drying a wood veneer, placing the wood veneer in a sodium hydroxide solution with the mass concentration of 10% at 50 ℃ for soaking for 8-10h, fishing out, washing to be neutral, drying, spraying a layer of toluene diisocyanate acetone solution with the mass concentration of 50% on the surface of the wood veneer, spraying a layer of flame-retardant waterproof isolating agent on the surface of the wood veneer after drying, and slowly drying at 40-45 ℃ to form a layer of flame-retardant isolating layer on the wood veneer, thereby obtaining the flame-retardant waterproof wood veneer; after the wood board is subjected to alkaline treatment, a large amount of hydroxyl on the surface of the wood board is exposed and can be compounded with sprayed toluene diisocyanate, so that the toluene diisocyanate is grafted on the surface of the board, and a large amount of hydroxyl is introduced into a polymer chain of the flame-retardant waterproof isolating agent and can react with the toluene diisocyanate grafted on the surface of the board, so that the flame-retardant waterproof isolating agent is compounded on the surface of the board to form a flame-retardant isolating layer;
and secondly, pre-compounding a plurality of flame-retardant waterproof boards by using a glue dipping compounding device to form a multi-layer composite board, preheating the multi-layer composite board at 80-90 ℃ for 20-30min, then carrying out hot pressing at 145-150 ℃, and then drying, cutting and sanding the hot-pressed board to obtain the plywood.
The specific preparation process of the flame-retardant waterproof isolating agent is as follows:
step 1: adding 3.5mol/L sodium methoxide methanol solution, dimethyl phosphite and 1, 4-dioxane into a reaction kettle at the same time, slowly heating to 50-55 ℃, adding acrylamide into the mixture, carrying out reflux reaction until TCL detection reaction is ended, adjusting the pH value of the solution to 7-7.5, adding water, standing, layering, and carrying out reduced pressure distillation to obtain aminated phosphate;
further, acrylamide and dimethyl phosphite are mixed according to the mass ratio of 1:1, 43-45mL of sodium methoxide methanol solution with the concentration of 3.5mol/L is added into each mole of acrylamide, and 110mL of 1, 4-dioxane 100-;
