Preparation method of inorganic coating layer on surface of woodware

A preparation method of an inorganic coating layer on a surface of woodware belongs to the field of inorganic material technologies. The method includes steps of: according to certain mass ratio, weighing aluminum dihydrogen phosphate, disodium hydrogen phosphate, silicon dioxide and water, and uniformly mixing and stirring the components to prepare a reaction agent 1; heating the reaction agent 1to 50-150 DEG C to carry out a reaction for 5-60 min to obtain a reaction agent 2; uniformly mixing and stirring the reagent agent 2 and a curing agent 1, ferric aluminum phosphate, to prepare a reaction agent 3; ball-milling magnesium hydroxide and calcium carbonate to perform activation pre-treatment to obtain a curing agent 2; and uniformly mixing and stirring the reagent agent 3 and the curing agent 2 to prepare an inorganic coating; coating woodware with the inorganic coating and performing heat insulation at 20-100 DEG C for 10-720 min to cure the inorganic coating, thus forming the inorganic coating layer on t
