Problems solved by technology

[0005] 1) The pattern on the printed decorative paper in the melamine-impregnated paper is generally obtained by printing with water-based ink, and the pigment in the water-based ink is prone to chemical reactions when it is irradiated by ultraviolet rays in sunlight, which eventually causes the water-based ink to fade;
[0006] 2) When the amino resin on the melamine-impregnated paper is irradiated by ultraviolet rays in sunlight, because the amino resin contains unsaturated groups and polar reactive groups, it is prone to photoaging reaction, and the final performance will decline rapidly

Abstract

The invention discloses antibacterial anti-ultraviolet-ray melamine impregnated paper and a preparation method thereof. The melamine impregnated paper comprises a melamine resin layer, a first anti-ultraviolet-ray urea-formaldehyde resin layer, plain base paper or printing decoration paper, a second anti-ultraviolet-ray urea-formaldehyde resin layer and an anti-bacterial anti-ultraviolet-ray melamine resin layer, wherein the melamine resin layer, the first anti-ultraviolet-ray urea-formaldehyde resin layer, the plain base paper or printing decoration paper, the second anti-ultraviolet-ray urea-formaldehyde resin layer and the anti-bacterial anti-ultraviolet-ray melamine resin layer are sequentially arranged from bottom to top. The preparation method comprises: 1) preparing raw materials; 2) impregnating plain base paper or printing decoration paper with an anti-ultraviolet-ray urea-formaldehyde resin layer; and 3) respectively arranging a melamine resin layer and an antibacterial anti-ultraviolet-ray melamine resin layer on both surfaces of the plain base paper or printing decoration paper treated in the step 2). According to the present invention, the melamine impregnated paper has excellent anti-ultraviolet-ray and antibacterial bactericidal effects; and the decorative plate obtained by gluing the melamine impregnated paper and the substrate has characteristics of wear resistance, scratch resistance, acid resistance, alkali resistance, blanching resistance, pollution resistance, aging fading resistance, good antibacterial effect and long service life.

Description

technical field [0001] The invention relates to an antibacterial and anti-ultraviolet melamine impregnated paper and a preparation method thereof. Background technique [0002] Melamine impregnated paper, full name melamine impregnated film paper, also known as "melamine" paper, is a kind of plain base paper or printed decorative paper impregnated with amino resin (such as: melamine formaldehyde resin and urea formaldehyde resin) and dried to a certain extent, Adhesive paper with a certain resin content and volatile content. [0003] The melamine-impregnated paper can be glued to each other or to the wood-based panel substrate by hot pressing. The surface of the decorative board prepared by it is hard, wear-resistant, scratch-resistant, acid and alkali resistant, scald-resistant, and pollution-resistant. It has a good application prospect. . However, the existing melamine-impregnated paper is prone to aging and fading during use, its performance declines rapidly, its servi...
