Description
【Technical field】
The invention belongs to wood-based plate preparing technical field is and in particular to a kind of novel environment friendly wood-based plate.
【Background technology】
China is large agricultural country, produces agricultural crop straw per year at 800,000,000 tons about, these substantial amounts of agricultural crop straws, traditional process
Mode is on-site incineration or piles up to get up to be allowed to degenerate, and so causes the problem of the aspects such as environmental pollution is serious.
At present, in terms of using agricultural crop straw processing artificial boards material, China achieves larger breakthrough.But, existing
Simple straw-based panel, because in agricultural crop straw raw material, content of lignin is relatively low, the medium-density plate being produced with it
Material mechanical strength is relatively low, and nail-holding ability is less.Simple straw-based panel, due to the wax content in agricultural crop straw relatively
Height, is difficult gum forming.
How to solve the problems, such as that current straw-based panel material mechanical strength is relatively low, be difficult gum forming, be ability
Field technique personnel's problem demanding prompt solution.
Since entering for 21st century, domestic wood-based panel industry obtains unconventional fast development, every year growth by 22%, 2009
Wood-based plate yield ten thousand stere more than 8000, year consumes adhesive about 5,000,000, becomes world's Wood-based Panel Production first big country.
At present, domestic and international wood-based plate manufacturing uses binding agent main still Lauxite, phenolic resin, melamino-formaldehyde tree
Fat etc..In the adhesive of this type, free formaldehyde content is higher, slowly releases toxic formaldehyde gas, to human body during use
Damage.In order to reduce the discharge of formaldehyde gases, domestic Research Thinking one side is the skill to original synthesis Lauxite
Art route is improved it is intended to reduce the content of free formaldehyde.As added the fomol catchers such as carbamide, tripolycyanamide；The opposing party
Face attempts to inexpensive biomass poly hydroxyl compound and prepares adhesive to replace formaldehyde system adhesive for raw material.Reported
Above-mentioned thinking in, the cost of starch-based glue stick is relatively low, is a kind of natural poly hydroxyl compound material having application prospect most.
The national conditions of corrugated board packing box it have been widely used in conjunction with domestic starch adhesive, starch adhesive forms sediment through new structure
Graft copolymerization after the MOLECULE DESIGN of powder and control oxidative cleavage, crosslinking, solves adhesion strength and resistance to water, for industry of artificial boards
Economically consider it is feasible.Over the past two years, there are exploratory development or the invention of part wood-based plate starch adhesive
Patent.But from the point of view of result of study starch-based glue stick be used for wood-based plate, however it remains resistance to water, adhesive strength, solid content and
A difficult problem for bin stability etc..The technological development aspect that wood-based plate is applied with starch adhesive also also has much difficult needs gram
Clothes.
【Content of the invention】
