Abstract

The invention provides a rollable heavy metal-free bamboo-wood fiber integrated wallboard and a preparation method thereof. The integrated wallboard comprises the following components by weight percentage: 20-25% of 8-type resin, 20-25% of plastic steel, 40-50% of calcium powder, 2.5-3% of birch powder, 2-3% of a foaming regulator, 1.5-2% of a stabilizer, 1-1.5% of a CPE plasticizer, 0.5-1% of a foaming agent, 0.2-1.5% of PE wax and 0.2-0.6% of stearic acid. The method includes: weighing all the raw materials in weight ratio, performing mixing and grinding into powder, then adding the powder into a high-low temperature mixer for hot mixing and cold mixing, then adding the product into a 65 extruder to cooperate with a grinding tool for extrusion forming, then putting the product into cooling water for cooling shaping, and performing cutting to obtain a finished board, and finally conducting coating of a PVC film. The materials adopted by the invention are low in price, are completely free of heavy metals and other components harmful to the human body, and are safe and environment-friendly, also the preparation method has few processes and simple technology, and the finished board also has the characteristics of high toughness, high deformation, rollability and small angle folding while having certain strength.

Description

Technical field [0001] The invention relates to the field of boards, in particular to a bamboo-wood fiber integrated wallboard that can be crimped, folded and is environmentally friendly and a preparation method thereof. Background technique [0002] With the progress of society and the change of people's ideas, green environmental protection has become a trend that is sought after. In terms of decoration products, all walks of life attach great importance to the use of product materials. Among them, bamboo and wood fiber, as a new type of material, has been widely used in various products because of its natural environmental protection and high performance. Among them, the bamboo-wood fiber integrated board is a recycled product made by combining bamboo and wood with plastic. In the traditional process, the bamboo-wood fiber integrated board is mainly based on wood (wood cellulose, plant cellulose), supplemented by thermoplastic polymer materials (plastics) and various process...
