Problems solved by technology

[0002] Existing decorative coated veneers, such as furniture, doors, windows, walls, etc., are mostly spliced ​​with veneers within 60cm, forming large gaps in the veneer, and the surface texture is not beautiful, and the surface flatness is poor, which cannot meet the needs of special-shaped parts. Blistering and coating treatment, and most of the existing elastic coated veneers are made of toxic materials such as PVC, which will produce toxic gases such as chlorine after being burned at high temperature or fire source. In order to overcome many defects of this product, there will be The veneer with a thickness greater than 0.15mm-0.4mm is spliced ​​to overcome the defects of uneven surface and unsightly texture by increasing toughness and softening. Shrinkage makes the cracks at the splicing continue to increase, causing the surface of the decorative veneer to become rough and uneven, which seriously affects the service life of the veneer, and cannot meet the processing and production of customer blisters and large-scale special-shaped parts

Embodiment 1

[0029] A method for preparing an ultra-wide, highly wear-resistant, plastic-absorbing, and environmentally-friendly veneer-coated method, comprising the following steps:

[0030] a. Composite: apply adhesive on the veneer, and then flatten the non-woven fabric on the veneer, the weight of the non-woven fabric is 4g / ㎡;

[0031] b. Toughening and constant humidity: put the composite veneer into the cooking equipment, the water temperature in the cooking equipment is raised from normal temperature to 45°C and then kept at the temperature, the duration of the heating is 1.5h, and then the temperature is raised from 45°C to 55°C, The heating duration is 2 hours, and the water in the cooking equipment is replaced once after cooking, and the temperature is slowly raised again. After repeating the above heating process twice, it is then dried by a belt dryer. Constant temperature and humidity in a closed environment until the moisture content of the veneer is 12%;
