Problems solved by technology

[0003] However, because the urea-formaldehyde resin layer in the melamine-impregnated paper has poor cigarette burning resistance (resistance to burning cigarettes), it is easily damaged, and due to the poor heat insulation ability of the urea-formaldehyde resin layer, it will also cause plain color base paper Or the printed decorative paper will turn yellow when heated, seriously affecting the user experience
In addition, as people's requirements are getting higher and higher, the wear resistance of the existing decorative boards made of melamine-impregnated paper needs to be further improved.

Abstract

The invention discloses wear-resistant and cigarette-burning-resistant melamine impregnated paper and a preparation method thereof. The melamine impregnated paper comprises a first melamine resin layer, a first urea-formaldehyde resin layer, plain base paper or printing decorative paper, a second urea-formaldehyde resin layer, a heat-insulation wear-resistant melamine resin layer and a second melamine resin layer which are sequentially arranged from bottom to top. The preparation method comprises the following steps: 1) preparing raw materials; 2) arranging the urea-formaldehyde resin layers on two sides of the plain base paper or printing decorative paper; 3) arranging the heat-insulation wear-resistant melamine resin layer on one surface of the plain base paper or printing decorative paper treated in the step 2); and 4) arranging the melamine resin layers on two surfaces of the plain base paper or printed decorative paper treated in the step 3). The melamine impregnated paper of theinvention has excellent wear resistance and cigarette firing resistance; a decorative plate obtained by gluing the melamine impregnated paper with a substrate has excellent wear resistance, scratch resistance, acid and alkali resistance, cigarette firing resistance and the like, and long service life.

Description

technical field [0001] The invention relates to a wear-resistant and cigarette-burning-resistant 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. The melamine impregnated paper can be pasted on the surface of the wood-based panel substrate by hot pressing, so that the surface performance and appearance quality of the wood-based panel substrate are significantly improved, and a hard, wear-resistant, scratch-resistant, acid and alkali resistant, scald-resistant, and durable Contaminated decking. [0003] However, because the urea-formaldehyde resin layer in the melamine-impregnated pape...
