Abstract

A molded laminated wood flooring and its production method, from the surface layer to the bottom layer are a hardened layer of wear-resistant surface adhesive film paper, a cured layer of decorative adhesive film paper, a base material layer, a balanced adhesive film paper cured layer, and a wear-resistant surface layer of adhesive film The cured layer of the paper is formed by impregnating and drying the base paper of the wear-resistant surface layer at least once with amino resin, and then coating the surface with at least one layer of high-gloss impregnating resin, which is cured by hot pressing after drying; the raw material components of the high-gloss impregnating resin include melamine Formaldehyde resin, plasticizer, brightener, leveling agent, curing agent, release agent; production methods include preparation of high-gloss impregnation resin; preparation of wear-resistant surface film paper; preparation of single-ply panels; preparation of high-gloss Planar boards; preparation of molded boards; molded boards are cut, health-balanced, grooved, and wax-sealed to make molded laminate flooring.

Description

technical field [0001] The invention relates to the technical field of laminate flooring, in particular to a high-gloss molded laminate floor and a production method thereof. Background technique [0002] Laminate flooring, also known as impregnated paper laminated wood flooring, consists of a wear-resistant layer, a decorative layer, a high-density substrate layer, and a balance (moisture-proof) layer. One or more layers of special paper impregnated with thermosetting amino resin, paved on the surface of particleboard, high-density fiberboard and other wood-based panels, with a balance layer on the back and a wear-resistant layer on the front, and then hot-pressed and formed. It has the characteristics of wear resistance, rich styles, impact resistance, deformation resistance, pollution resistance, flame retardant, moisture resistance, environmental protection, no fading, easy installation, easy care, and can be used for floor heating, etc. [0003] The existing manufactur...
