Abstract

The invention relates to wear-resistant melamine impregnated paper, a preparation method and application thereof. The wear-resistant melamine impregnated paper comprises a polyurethane primer layer, amelamine resin layer containing a wear-resistant agent and printing paper subjected to melamine resin impregnation treatment from top to bottom, wherein the polyurethane primer layer is prepared fromthe following raw materials in parts by weight: 70-90 parts of a water-based resin, 0.5-1 part of a defoaming agent, 20-30 parts of water, 2-3 parts of an alkali swelling rheological aid, 0.5-1 partof an antiseptic bactericide and 0.2-0.4 part of a demolding agent. According to the invention, in a bonding process of wear-resistant melamine impregnated paper and a base material, a polyurethane primer is directly coated without polishing, so that labor cost is saved, and production efficiency is improved; and the polyurethane resin can improve the adhesive force between the polyurethane primerlayer and the base material and the melamine resin layer containing the wear-resistant agent, the surface of the melamine resin layer containing the wear-resistant agent contains a large amount of exposed aluminum oxide, and the exposed wear-resistant agent is covered after the polyurethane resin is sprayed, so that the wear-resistant agent is prevented from making contact with a steel plate in the subsequent hot pressing procedure.

Description

technical field [0001] The invention relates to the technical field of decorative materials, in particular to a wear-resistant melamine-impregnated paper, a preparation method and an application thereof. Background technique [0002] Melamine board, the full name of melamine impregnated film paper veneer wood-based board, is to put printing paper with different colors or textures into the melamine resin adhesive, soak it, and then dry it to a certain degree of curing before laying it on the particleboard, fireproof A type of decorative board obtained by hot pressing the surface of base materials such as board, medium density fiberboard and plywood. Since the printing paper in the melamine board can choose any pattern such as wood grain, etc., and the melamine board has excellent scratch resistance, heat resistance, corrosion resistance and pollution resistance, it is widely used in the field of decorative buildings. [0003] The current melamine board often adopts the metho...
