Production method of decorative veneer laminated sheet

Abstract

The invention provides a production method of decorative veneer laminated boards, which includes the following process steps: performing cooking and softening treatment on low-grade logs, then rotary cutting and cutting into wood veneers, and then drying; taking half of the wood veneers, using Soak in phenolic resin impregnation solution for 3-10 minutes; dry at 50-80°C for 1-1.5 hours; unimpregnated wood veneers and impregnated wood veneers are assembled along the grain at intervals; the slabs are aged for 10 -30min, and then sent to a pre-pressing machine for pre-pressing for 3 to 10 minutes; sent to a hot press for hot pressing; natural cooling, and then sawing strips of equal width required by a certain thickness to obtain the decorative veneer laminated board of the present invention. The veneer laminate produced by the method has the advantages of low cost, obvious strip shape, strong contrast, good appearance, and stable size and performance.

Description

technical field [0001] The invention relates to the technical field of wood composite materials, in particular to a production method for decorative veneer laminated boards. Background technique [0002] The reality of lack of forest resources in my country greatly limits the use of wood in construction and interior decoration. Reasonable use of existing domestic low-grade wood (referring to artificial forest wood or wood with poor mechanical properties although it is natural forest), is an urgent problem to be solved. Laminated veneer lumber is a new type of engineering wood material made of rotary-cut wood veneers after drying, gluing, forming along the grain, and pressing. Due to its stable performance, high strength, easy processing, and can replace large-diameter solid wood The use and other advantages are favored by the market. However, the production technology level of LVL in my country is relatively backward, and it is difficult to meet the market's requirements f...

AI Technical Summary

Problems solved by technology

However, the production technology of laminated veneer in my country is relatively backward, and it is difficult to meet the market's requirements for high-performance laminated veneer.

In a nutshell, the disadvantages are: wood veneers are usually not graded, and the variability is large, resulting in unstable product performance; the slab structure is unreasonable and the wood veneer impregnation and strengthening treatment takes a long time and high cost, which hinders the single Market promotion of plate impregnation enhancement technology, etc.
