Problems solved by technology

However, the dimensional change rate of the current PVC floor is still a problem. At the same time, the wood-based panel has low bending strength, and a slight stress will cause the floor to break.

Abstract

The invention provides a high-toughness heat-resistant shrinkage artificial board and a preparation method thereof. The preparation method is as follows: (1) Prepare modified silicon nitride; (2) After mixing PVC resin, calcium zinc stabilizer, dioctyl phthalate, ultraviolet absorber UV‑327, and toner on a high-speed mixer, Add kaolin, modified silicon nitride, 4,4'-diaminodiphenylmethane, sodium alcohol ether carboxylate, and Artemisia annua seed gum, mix and then cool and discharge; The kneading machine is started for kneading. During the kneading process, triangular bagging and traction are carried out, and finally the thin film is released; (5) under high temperature and pressure, use a pressure forming machine to press the tablet, keep the pressure and cool, and then press and cold press to obtain Wood-based panels. The high-toughness heat-resistant shrinkable wood-based panel of the invention has good dimensional stability and high bending strength.

Description

technical field [0001] The invention relates to the field of wood-based panel materials, in particular to a high-toughness heat-resistant shrinkage wood-based panel and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) plastic floor, also known as stone-plastic floor, has the characteristics of environmental protection, easy paving, strong decoration, easy cleaning and maintenance, and fire prevention. In European and American countries, PVC plastic flooring has been widely used in public places and household floor decoration. PVC plastic flooring is mostly used in public places such as libraries, hospitals, and shopping malls for floor decoration in China. PVC flooring is mainly due to its light weight, high strength, moisture-proof, anti-corrosion, mildew-proof, and good foot feel. Compared with ceramic tiles and wooden floors, it has low maintenance cost, no formaldehyde, no radiation, and the use process is safe and environmentally fri...
