Abstract

Disclosed are low-formaldehyde-emission abrasion-resistant and moisture-proof laminate wood flooring and a production and laying method for the laminate wood flooring. The laminate wood flooring is provided with an impregnated abrasion-resistant paper layer, an impregnated separation paper layer, an impregnated decorative paper layer, a high-density fiberboard layer and an impregnated balance paper layer successively from the surface layer to the bottom layer. Impregnated balance paper, a high-density fiberboard, impregnated decorative paper, impregnated separation paper and impregnated abrasion-resistant paper which are sacked successively are subjected to hot pressing at the temperature ranging from 175 DEG C to 185 DEG C and under the pressure in a range of 5MPa to 9MPa for 40S to 45S to be produced into a large semi-manufactured plate; the large semi-manufactured plate is subjected to splitting, healthy balance treatment and rabbet machining to be manufactured into small plates; the small plates are manufactured into laminate wood flooring by coating polyurethane lacquer at peripheral rabbet positions; and sawing section fibers of the flooring is subjected to the first coating through the polyurethane lacquer during laying, the polyurethane lacquer is dried till the lacquer surface is tacky but not sticky when touched with fingers, and the flooring is laid after the second coating is performed.

Description

technical field [0001] The invention relates to the technical field of laminate flooring, in particular to a low-formaldehyde emission, wear-resistant, moisture-proof laminate floor; the invention also relates to a production method and floor covering for a low-formaldehyde release, wear-resistant, moisture-proof laminate floor installation method. 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. The moisture-proof performance of laminate flooring is mainly determined by the moisture-proof performance of the floor substr...
