Formulation and production and recycling process of carbonized solid wood high-density fiber composite board

Abstract

The invention discloses a formula of a carbonized solid-wood high-density fiber composite board and a producing and recycling process. The raw materials are carbonized wood fiber powder and highly dehydrated carbonized materials, the characters of plastic fusion has been improved, hydrophilic factors in the carbonized wood are recombined, the balance point (commonly known as moisture line) of moisture absorption of the wood is lowered and is not easy to be affected by the surrounding, and quality of the products can be guaranteed. The formula thoroughly overcomes the defects of similar products in the market and has the advantages of water resistance, insect prevention, corrosion prevention, flame retarding and the like. Meanwhile, the formula can be used for decorations such as sculpture, veneering and spraying, is free of formaldehyde and can be recycled and reused completely.

Description

technical field [0001] The invention relates to the field of building composite materials, in particular to a carbonized solid wood high-density fiber composite board formula and a production and recycling process. Background technique [0002] Wood-plastic composite material is a new type of composite material, which is usually made by mixing thermoplastics and plant fibers. It has excellent properties and is an excellent substitute for natural wood. For example, Chinese Patent Publication No. CN103360778A is a production process of high-strength wood-plastic composite materials, Chinese Patent Publication No. CN103965645A is a kind of wood-plastic board formula, and Chinese Patent Publication No. CN103554951A is a kind of wood-plastic composite material, all of which are based on wood powder or plant fiber Mixing of plastics and other formulations for the production of wood-plastic materials. However, in the production process, the following problems were found. Because w...

Problems solved by technology

However, in the production process, the following problems were found. Because wood powder is a polar substance, and plastic is a non-polar substance, the fusion of the two needs to be improved with the help of other chemical agents; The moisture content can be very low, but when the wood powder is exposed to the external environment during production, it will absorb water and moisture, which will reduce the strength and quality of the final wood-plastic product
