Abstract

The invention discloses a method for preparing a hydrophobic and antibacterial decorative veneer, specifically relates to the technical field of hydrophobic and antibacterial decorative veneer, and specifically includes the following steps: Step 1: firstly select one piece of particleboard, one piece of medium density fiberboard, and one piece of plywood, and put them all together Put it into the dryer, dry it at 60-80°C for 10-20 minutes, dry it to a moisture content of 8-10%, then take it out of the dryer and wait to cool to 35-40°C When it is used, put it aside for later use; step 2: add 40-60 parts of cotton fiber, 10-20 parts of hemicellulose, and 20-40 parts of lignin. The invention greatly improves the hydrophobic and antibacterial properties of the decorative veneer, so that the decorative veneer is not only not easy to damage, but also more durable, and can protect human health, is not easy to breed bacteria, and has better safety.

Description

technical field [0001] The invention belongs to the technical field of decorative veneer, in particular to a preparation method of hydrophobic and antibacterial decorative veneer. Background technique [0002] Decorative veneer substrates are generally precious tree species with beautiful patterns and excellent texture, and the production requires a large diameter, which often limits its development. Therefore, with the advancement of technology and the development of production, a new artificial substrate has emerged. It is generally divided into natural veneer, which is made of precious tree species, sliced ​​or semicircularly cut after hydrothermal treatment. The difference between it and integrated veneer and artificial veneer is that the wood has not been separated and reorganized, and other substances such as adhesives are added. The composition is a veritable natural material. In addition, it has high requirements on the material of wood, which is often precious wood....
