Problems solved by technology

[0002] The current impregnated paper is basically made of non-woven wood pulp mixed with PE and plant fibers. It has strong absorption and anti-solution ability, and is widely used in cabinets, wardrobes and composite floor veneers. Base paper layer, plain color layer, etc., the adhesion between the layers is insufficient, and the phenomenon of separation between the layers is easy to occur, and the impact resistance is low, and it is easy to cause damage to most of the impregnated paper due to external impact, and even a large area. It falls off from cabinets, wardrobes, and floorboards, and the service life is low; in addition, the current impregnated paper has low stain resistance, easy to attach stains and difficult to remove, affecting use

Abstract

The invention relates to the field of impregnated paper and in particular to shock-proof self-cleaning impregnated paper and a preparation method thereof. The impregnated paper comprises a raw paper layer, a hot melt adhesive wet layer, a printing pattern layer, a wear-resisting adhesive layer and a nano TiO2 self-cleaning layer which are installed successively from bottom to top. Mesh density ofthe hot melt adhesive wet layer is 100-130 mesh / m<2>. The wear-resisting adhesive layer is prepared by a melamine-formaldehyde compound adhesive. The nano TiO2 self-cleaning layer is prepared by nanoTiO2 self-cleaning paint. Through installing the nano TiO2 self-cleaning layer on the outer surface, the impregnated paper provided by the invention is capable of degrading dust particles and dirt attached to the surface of the impregnated paper by using the photocatalysis, so as to improve self-cleaning property and anti-pollution property of the impregnated paper; through installing the hot meltadhesive wet layer, an adhesive force between the raw paper layer and the printing pattern layer can be improved, interlayer separation is avoided, and the rebound resilience and shock resistance ofthe impregnated paper can be improved through using flexibility of the hot melt adhesive wet layer, so that the impregnated paper is not easily damaged in a large area because of shock.
