Description

Bamboo-wood composite waterproof wallboard

Technical Field

The utility model relates to an wood-based plate technical field, concretely relates to bamboo wood composite waterproof wallboard.

Background

The recombined bamboo not only has the basic characteristics of bamboo, but also has the advantages of good mechanical property, high surface strength, good size stability and the like, and is a good veneering material. The EVA waterproof board has better corrosion resistance, low temperature resistance and stretchability, and can meet the requirement of the wallboard on corrosion resistance. The oriented structure shaving board is formed by slicing logs into boards with specified sizes and pressing the boards along the grain direction, has the characteristics of high strength, stable size and the like, and can provide a stable wallboard base layer. The two waterproof coatings of acrylate and polyurethane have the advantages of environmental protection and good weather resistance, and have the effects of decoration and heat insulation. The invention designs the bamboo-wood composite waterproof wallboard with both decoration and practicability by taking the oriented structure shaving board as the substrate and combining the characteristics of other materials.
