Method for preparing solid-wood composite strengthened plates

Abstract

The invention relates to a method for preparing solid-wood composite strengthened plates, which is characterized in that a solid-wood composite strengthened plate is prepared by the following steps: (1) a step of manufacturing a thin wood plate, which is to cut hard wood into dimension lumber, soak the dimension lumber in hot water at a temperature above 50 DEG C, perform bonding by use of water-resistant high-strength adhesive, perform solid-pressure molding through a cold press and a pressurizer and slice the obtained product into a thin wood plate; (2) a step of overlaying, which is to adopt an applicator to smear base glue on a density board, paste the thin wood plate onto the density board, send the obtained product into a hot press for pressing, perform polishing through a sander and prepare the obtained product into a base plate; and (3) a step of covering a wear-resistant layer, which is to cover the base plate with an aluminum sesquioxide wear-resistant layer, press through pressure at a temperature above 200 DEG C, perform hot-press treatment processing for 1 minute and prepare the obtained product into the solid-wood composite strengthened plate. The solid-wood composite strengthened plate has the characteristics of super wear resistance, strong paint-film smooth adhesive force, high transparency, acid-base resistance, strong flame-retardant moisture resistance, insusceptibility to cracking and bursting and low cost.

Description

technical field [0001] The invention relates to a preparation method of a solid wood composite reinforced board. Background technique [0002] At present, domestic building decoration materials mostly use imported composite high-density reinforced boards. This material is made by pasting paper on high-density boards, impregnated with melamine, and then thermally compounded with aluminum oxide. This product has the following problems: the paper surface pasted on the high-density board is unreal, the wear resistance is poor, the process is complicated, and the production cost is high. There are many types of high-density composite boards produced in China. One is to glue wooden veneers on both sides of the high-density boards, and coat the surface of the wooden veneers with a moisture-proof paint film; there is also a composite board that uses high-density boards, MDF is paved with hard wood boards, and the wood layer is double-sidedly sealed with high-grade unsaturated resin...
