Abstract

The invention relates to an impregnated resin, an impregnated film adhesive, manufacturing methods of the impregnated resin and the impregnated film adhesive, and a laminated floor. According to the present invention, the impregnated resin comprises a melamine formaldehyde resin, urine phthalic acid, and a formaldehyde scavenger, wherein 810-860 parts by weight of formaldehyde, 330-350 parts by weight of water, 700 parts by weight of melamine, 30-40 parts by weight of urea and 10-20 parts by weight of caprolactam are subjected to thermal insulation, then 40-65 parts by weight of urea, 20-40 parts by weight of diethylene glycol and sodium hydroxide are added to prepare the melamine formaldehyde resin, 5 parts by weight of a semicarbazide hydrochloride is dissolved in 12-15 parts by weight of water, 7-8 parts by weight of crystallized sodium acetate is dissolved in 5-7 parts by weight of dimethylformamide, the two obtained solutions are mixed to obtained the formaldehyde scavenger, and the impregnated resin is prepared from 1000 parts by weight of the melamine formaldehyde resin, 5-8 parts by weight of the urine phthalic acid, and 10-15 parts by weight of the formaldehyde scavenger; base paper is impregnated in the impregnated resin and dried to prepared the impregnated film adhesive; and the impregnated film adhesive and a high density fiber plate are subjected to hot pressing so as to prepare the laminated floor.

Description

technical field [0001] The invention belongs to the technical field of laminate flooring materials, and in particular relates to an impregnated melamine resin for laminated wood floor impregnated film paper and a manufacturing method thereof; the invention also relates to an impregnated film paper and a manufacturing method thereof; the present invention also relates to a Kind of laminate flooring. Background technique [0002] The impregnated film paper veneer wood-based panel is generally composed of film paper and base material. Compared with solid wood sawn timber, impregnated film paper veneered wood-based panels have low raw material requirements, wide sources, high wood utilization rate, many product specifications, good processing performance, and diversified surface decoration, and the surface is wear-resistant and durable. It has excellent properties such as heat resistance, water resistance, chemical pollution resistance, smooth surface and easy cleaning, and has...
