Problems solved by technology

But it also has its inherent disadvantages, because the edges are rough and easy to absorb moisture
In addition, due to the large volume of particle board, the furniture made of it is relatively heavy compared with other boards, and it is more prone to defects during processing.

Abstract

The invention relates to a waterproof board, in particular to a waterproof composite shaving board and belongs to the field of furniture boards. The waterproof board comprises an upper surface layer, fiber layers, shaving layers and a lower surface layer, wherein a certain amount of fiber layers and shaving layers are arranged between the upper surface layer and the lower surface layer, and the fiber layers and the shaving layers are arranged alternately. The shaving layers are formed by a shaving material and reinforcing fiber which are composited through thermosetting resin under the heating and pressing effects. A waterproof coating is sprayed onto the upper surface layer and the lower surface layer, waterproof substance in the waterproof coating is a hydrophobic composition which is designed according to a hydrophobic structure on the lotus leaf surface and has good dual hydrophobic property of the lotus leaf. The waterproof board has the advantages of being high in strength and good in machinability and waterproofness.

Description

technical field [0001] The invention relates to a waterproof board, in particular to a waterproof particleboard, which belongs to the field of furniture boards. Background technique [0002] At present, one type of waterproof boards is to apply waterproof coatings on ordinary boards. There are two types of waterproof materials: one is polyurethane waterproof coatings. Such materials are generally made of polyurethane and coal tar as raw materials. The tar gas it volatilizes is highly toxic and not easy to remove, but when using this kind of paint, it is generally diluted with organic solvents such as toluene and xylene, so it is also toxic; the other type is polymer cement-based waterproof paint . It is composed of a variety of water-based polymer emulsions and high-quality cement mixed with various additives. The flexibility of the polymer (resin) and the rigidity of the cement are integrated, making it excellent in impermeability and stability. Its advantages are conve...
