Abstract

The invention provides a manufacturing method of self-cleaning decorative veneer. The method is characterized by comprising the following steps: S1, carrying out surface treatment: sanding veneer to 300 meshes, soaking in 3% pretreatment solution for 10-15min, and controlling the treatment temperature to be 20-25DEG C; S2, dipping and drying: dipping the pretreated veneer into resin, controlling the sizing amount to be 120-160%, and drying for 60-120s at the temperature of 90-120 DEG C; S3, carrying out surface coating, coating the dried decorative veneer with a nano TiO2-organosilicone modified coating, wherein the veneer treated in the S2 is evenly coated with the coating at a speed of 50mm / min; then, drying for a week at the room temperature under the condition that the humidity is 60-80% so as to finally obtained the self-cleaning decorative veneer.

Description

technical field [0001] The invention belongs to the field of wood processing, and in particular relates to a method for manufacturing self-cleaning decorative veneer. Background technique [0002] With the continuous development of my country's decorative material industry, decorative veneer is well known to the public, which not only alleviates the contradiction between supply and demand of precious wood in my country, but also has a decorative effect far superior to ordinary impregnated paper veneers and PVC veneers. However, decorative veneer itself has the properties of wood. It is a porous material and has anisotropy. post-management costs. Therefore, it is of great significance to endow it with self-cleaning, anti-corrosion, waterproof and other properties by chemically or physically modifying the surface of artificial decorative veneer. [0003] At present, technologies that imitate some natural phenomena to solve practical problems in human life have attracted more...
