Problems solved by technology

my country's poplar timber forest area is 3.09 million hectares, accounting for about 40% of the country's poplar plantation area, and the poplar can grow quickly in 6 to 8 years. However, due to the soft material, loose structure and low strength of poplar The disadvantage is that it can only be used for pulp wood and plywood core material, which limits the wide and efficient utilization of poplar wood, and the current situation of tight wood supply has not been alleviated
[0005] At the same time, because poplar veneer is a polar natural porous material, it is difficult to glue foamed styrene board and poplar veneer with low-cost urea-formaldehyde resin commonly used in the wood processing industry, which affects the development of this type of lightweight board

Abstract

The invention belongs to the field of manufacture of artificial boards, and particularly relates to a method for gluing a poplar veneer with a foam styrene plate to manufacture a light artificial board, which particularly relates to a method for gluing by the aid of low-cost urea resin. The method includes the steps of impregnation and gluing, the foam styrene plate is impregnated in interface impregnation liquid at room temperature and then is dried, the impregnated foam styrene plate and the poplar veneer coated with the urea resin are in hot-press gluing, and the light board is obtained. The interface impregnation liquid mainly consisting of natural lignin and tannin is used for impregnation to process the foam styrene plate, the foam styrene plate and the poplar veneer are glue by the aid of the urea resin, and plastic failure rate (the damage rate of the foam styrene plate) of the light board can reach more than 90%. In addition, the method has the advantages that the range of raw materials is wide, configuration is simple, service is convenient, an interface improvement effect is remarkable, and the like.

Description

Technical field [0001] The present invention is the field of artificial board manufacturing. It specially involves a glue method for popping up and foamyrene boards to manufacture lightweight artificial boards. Especially the method of using low -cost jelly -formaldehyde resin for glue. Background technique [0002] With the steady development of my country's economy, the demand for wood consumption in industrial production and people's lives has continued to increase, and my country's current wood production cannot meet the demand in terms of quality and quantity.In the past ten years, my country has created a large number of artificial forests every year, with a cumulative artificial forest area of ​​34 million hectares, which is the first of the world. [0003] The light quality of furniture components, on the one hand, is affected by modern plate -type disassembly furniture, saving raw materials and reducing prices. On the other hand, it is also demanding from packaging and t...
