NOVELTY - Preventing cracking of wood, comprises impregnating wood with silicone water repellent, spraying waterproof primer on the wood surface and end face after waterproof impregnation treatment, and performing first drying treatment to obtain a primer layer, spraying the epoxy resin waterproof coating, and performing second drying treatment to obtain the middle coating, spraying the waterproof topcoat, and performing the third drying treatment to obtain the wood treated with anti-crack protection, where the waterproof primer comprises 25-40 pts. wt. aqueous silicone resin, 3-8 pts. wt. styrene-acrylic emulsion, 3-6 pts. wt. silane coupling agent, 10-15 pts. wt. graphene oxide, 6-10 pts. wt. polysorbate, 2-5 pts. wt. initiator, 6-13 pts. wt. Polyhedral oligomeric silsesquioxane-acrylate, 3-7 pts. wt. polyhedral oligomeric silsesquioxane-ammonia, 4-9 pts. wt. dispersant and 30-45 pts. wt. water. USE - The method is useful for preventing cracking of wood of archaizing building material, where the nursing is easy to crack, mildew, damage the wood product, influence the beautiful and use function and the wood use and appearance influence is large to crack. ADVANTAGE - The method improves the waterproof performance of the wood, so as to reduce the wood deformation cracking under the high temperature and high humidity environment, and improves the anti-cracking protection performance of wood.
