Problems solved by technology

Aluminum is soft, has good ductility, and can be colored or printed; aluminum is not easy to rust, fireproof, light in weight, easy to process and shape, and can be widely used as high-grade decorative materials for construction, furniture, indoor and outdoor decoration and vehicle decoration; aluminum It has extremely high recyclability, and the characteristics of recycled aluminum are almost the same as those of primary aluminum. However, the adhesive used in processing is more expensive, the material surface treatment and hot-pressing composite process are complicated, energy consumption is high, and environmental pollution is large; The pressing cycle is long, the production efficiency is low, and the investment in equipment is large, resulting in a high price of decorative panels, which limits its popularization and application

Abstract

The invention discloses an aluminum-wood composite decorative board and a preparation method thereof. The aluminum-wood composite decorative board is prepared from 30-55 parts of raw kraft paper, 25-55 parts of aluminium foil, 19-40 parts of phenolic resin, 11-19 parts of sodium hydroxide, 13-19 parts of anhydrous ethanol, 8-22 parts of pectin, 20-34 parts of polyvinyl alcohol, 12-23 parts of polyvinyl acetate emulsion, 12-22 parts of polyvinyl butyral, 7-18 parts of starch, 8-22 parts of kaolin and 12-25 parts of deionized water. The aluminium foil and the kraft paper of the aluminum-wood composite decorative board are well bonded together, so that the aluminum-wood composite decorative board is high in compactness. The aluminum-wood composite decorative board is high in interface stability and high in bonding strength.

Description

technical field [0001] The invention belongs to the field of material chemistry and relates to a decorative material, in particular to an aluminum-wood composite decorative board and a preparation method thereof. Background technique [0002] Wood is the only renewable and naturally degradable ideal environmental material among the four major materials (steel, cement, wood and plastic) in the world today. It has excellent performance in energy saving and environmental protection, and is irreplaceable by other materials. As an environment-friendly material, wood has attracted more and more people's attention and recognition, and is widely used in construction, furniture manufacturing and other industries. Due to the increasing shortage of forest resources in the world, China has become one of the largest timber importers. By 2010, my country's timber market demand will reach more than 200 million cubic meters. With the rapid development of China's economy, the demand for woo...
