Paint-free abrasion resistant veneer and preparation technique thereof

Abstract

The invention discloses a paint-free abrasion resistant veneer which comprises a base material layer; one surface of the base material layer is stuck with a first surface layer; and the first surface layer is first glue film blank paper which is coated with a first alumina layer which is dried and solidified to form first glue film paper. The paint-free abrasion resistant veneer preparation technique comprises the surface layer manufacture step, the base material selecting step, the blank-matched sticking step, the high temperature overlaying step and the deburring decoration step. The surface layer manufacture step comprises the steps of selecting the natural wood-grain colored or plain decorative paper of series designs and colors; selecting melamine-resin adhesive or melamine modified urea-formaldehyde resin as a cementing compound; forming the glue film blank paper by the decorative paper after being dipped by the cementing compound; spraying alumina on the outer surface of the glue film blank paper to form a surface layer so as to form the glue film paper; the base material selecting step comprises the steps of selecting veneers or blockboards; and the blank-matched sticking step comprises the steps of butting the inner surface of the glue film paper and sticking one surface of the selected veneer or respectively butting the inner surfaces of two pieces of glue film paper and sticking the two surface of the selected veneer to form a blank-matched decorative veneer. The paint-free abrasion resistant veneer and preparation technique thereof have the advantages of convenient processing, beauty and practicability, high strength, long service life and good environmental protection property.

Description

technical field [0001] The invention relates to the technical field of veneer manufacture, in particular to a paint-free wear-resistant veneer and a preparation process thereof. Background technique [0002] Traditional melamine impregnated film paper veneer wood-based panels. It is a decorative board formed by soaking paper with different colors or textures in melamine resin adhesive, and then drying to a certain degree of curing. In the production process, it is generally composed of several layers of paper, and the number depends on the application. Generally, it is composed of surface paper, decorative paper, covering paper and so on. The surface paper is placed on the top layer of the decorative board to protect the decorative paper, making the surface of the board highly transparent after heating and pressing, and the surface of the board is hard and wear-resistant. Decorative paper, that is, wood grain paper, is an important part of the decorative board. It has a b...

[0005] Another example is the patent No. 200710062309.3 "Production Process of Melamine Veneer Decoration" which mentions "glue-applied closure treatment" and "glue-applied closure treatment". In summary, the defects exposed by this patented melamine veneer process: 1. Glue again The room temperature is closed, and the production time is too long "60 minutes" for an hour. It is not good for the development of the enterprise to increase the production capacity. To increase the production capacity, it is necessary to use a lot of manpower and a huge site, which increases a lot of costs and is not good for the development of the enterprise.

2. The second glue coating process will cause secondary pollution, which increases the difficulty of meeting the requirements of environmentally friendly products

3. Re-coating increases the moisture content of the base material. As mentioned in the hot pressing, the increase of the moisture content of the base material after re-coating will generate stronger steam during hot pressing. When a certain steam force is reached, it will cause a waterfall. , so that there will be a large number of sub-boards; and the high-concentration formaldehyde smell emitted in the hot-pressed production workshop will increase the pollution of the working environment, and will also bring extended damage to consumers in the later stage
