Description
Technical Field
The invention relates to melamine resin, in particular to anti-fingerprint melamine resin and a preparation method and application thereof.
Background
With the improvement of living standard and aesthetic sense of people, the consumption trend is changing continuously, and many consumers require fashionable, personalized and magnificent home decoration materials and environment-friendly, clean, safe and high-quality materials. More than 80% of household products in the market are decorative artificial board materials. In the artificial board surface decorating material, the decorating adhesive film paper is one of the decorating materials with the largest component accounting for the total consumption of the decorating materials in the world. The decorative adhesive film paper is made of special titanium powder paper through printing, impregnation and pressing. The artificial board is decorated with the decorative adhesive film paper, so that various defects on the surface of the artificial board can be covered and eliminated, and the artificial board has a fresh, elegant, harmonious and beautiful appearance.
The melamine impregnated bond paper is a bond paper with surface decoration treatment, which is a bond paper with certain resin content and volatile matter content, which is obtained by impregnating plain base paper or printing decorative paper with amino resin (melamine formaldehyde resin and urea formaldehyde resin) and drying to a certain degree, and can be mutually glued or glued with an artificial board substrate through hot pressing. In the aspect of hot pressing, different steel plates are selected, and resin layers of the melamine impregnated bond paper are thermally cured into different shapes, such as: high gloss, matte, super matte, pitted surface, deep relief, etc. The decorative product pressed and pasted by the highlight steel plate has light pollution, while the decorative product pressed and pasted by the matte and super-matte steel plate not only eliminates the light pollution, but also has a sandy granular feeling in touch. However, the decorative surface can be contacted by both hands of people frequently, thereby a finger print is formed on the decorative surface, if a high-gloss product is adopted, the finger print is easy to eliminate, the attractiveness of the decorative material is not influenced, but on the matte and super-matte products, the moisture and oil stains in the finger print are easy to fill in the matte and super-matte convex-concave surfaces, so that the matte effect is locally lost, a reflector is formed, the moisture and oil stains in the convex-concave surfaces are also difficult to eliminate, the obvious finger print influences the attractiveness of the decorative material from the reflection angle, people hope to eliminate the influence of the fingerprint on the decoration, the fingerprint cannot be transferred or attached, the decorative surface is kept in a non-staining state, and the melamine resin coated ink layer can fully embody the attractiveness and gorgeous effects. The finger print contains water, inorganic salts, urea, oil, etc. A large amount of dust, bacteria and the like are bred after being attached to the decorative surface for a long time, and the bacteria are easily introduced to the human body through repeated contact of hands and the decorative surface. The melamine impregnated bond paper is hot-pressed on a base material through a matte and super-matte steel plate, and a film on the final surface has matte and super-matte effects. The light pollution is reduced, the comfortable frosted touch is increased, but the fingerprint is difficult to eliminate.
Today, anti-fingerprint technology has been applied to the industries of electronics, glass, metal and the like, but has not been applied to the furniture decoration industry.
