[0002] There are many bamboo and wood kitchen utensils, including: containers, chopping boards, bottom trays for bowls and cups, chopstick and knife boxes, etc. In addition, they also have unique shapes. Besides the usual square, round, heart-shaped, cylindrical shapes, there are also special irregular utensils such as outer-square and inner-round, gourd-shaped, boat-shaped, fish-shaped, etc. The delicate and collectible bamboo and wood kitchen utensils also reflect the comfort and care in the kitchen. Compared with cold glass products and monotonous plastic products, the steady and elegant bamboo and wood products appear more cordial. Compared with ceramic, glass, and plastic tableware, bamboo and wood tableware also has very prominent advantages: heat preservation, heat insulation, and durability. However, the humidity in the kitchen is relatively high. Traditional bamboo and wood products are prone to moisture and mildew in this environment, and compared with kitchen utensils made of other materials, bamboo and wood kitchen utensils are more likely to crack. Therefore, it is necessary to design an aqueous coating layer for bamboo and wood kitchen utensils with waterproof, mildew-proof and crack-proof functions. Content of the Utility Model
