Abstract

Molded laminated wood flooring and its production method, from the surface layer to the bottom layer are a hardened layer of wear-resistant decorative adhesive film paper, a substrate layer, and a cured layer of balanced adhesive film paper, wherein the cured layer of wear-resistant decorative adhesive film paper is impregnated Amino resin, drying; the surface is impregnated, coated or sprayed with wear-resistant glue, and dried; then impregnated with high-gloss impregnated resin, dried, and hot-pressed; the high-gloss impregnated resin is prepared by the following steps Obtained; high-gloss impregnation resin raw material components include melamine formaldehyde resin, plasticizer, brightener, leveling agent, curing agent, release agent; production method includes preparation of high-gloss impregnation resin; preparation of wear-resistant decorative film Paper; preparation of single veneer boards; preparation of high-gloss flat boards; preparation of molded boards; molded boards are cut, balanced, grooved and sealed to make molded laminate flooring.

Description

Technical field [0001] The invention relates to the technical field of reinforced wood flooring, in particular to a high-gloss molded reinforced wood flooring and a production method thereof. Background technique [0002] Laminated wood flooring, also called impregnated paper laminated wood flooring, is composed of a wear-resistant layer, a decorative layer, a high-density substrate layer, and a balanced (moisture-proof) layer. It is a floor made of one or more layers of special paper impregnated with thermosetting amino resin and spread on the surface layer of wood-based panels such as particleboard and high-density fiberboard, with a balance layer on the back and a wear-resistant layer on the front. It has the characteristics of wear resistance, rich styles, impact resistance, deformation resistance, pollution resistance, flame retardant, moisture resistance, environmental protection, no fading, simple installation, easy care, and can be used for floor heating. [0003] The exis...
