Wood-based plate yield consumes adhesive about 5,000,000 more than ten thousand stere more than 8000, year, becomes world's Wood-based Panel Production the first big country.
At present, binding agent main still Lauxite, phenolic resin, the melamino-formaldehyde tree that domestic and international wood-based plate manufacturing uses
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 gas, on the one hand domestic Research Thinking 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 catcher such as carbamide, tripolycyanamide；The opposing party
It is that raw material prepares adhesive to replace formaldehyde system adhesive that face attempts to inexpensive biomass poly hydroxyl compound.Reported
Above-mentioned thinking in, the cost of starch-based glue stick is relatively low, is the one natural poly hydroxyl compound material having most application prospect.
Be widely used in the national conditions of corrugated board packing box in conjunction with domestic starch adhesive, starch adhesive forms sediment through new structure
The MOLECULE DESIGN of powder with control graft copolymerization after oxidative cleavage, crosslinking, solve adhesion strength and resistance to water, for industry of artificial boards
Economically consider it is feasible.Over the past two years, there have been exploratory development or the invention of part wood-based plate starch adhesive
Patent.But starch-based glue stick is for wood-based plate from the point of view of result of study, however it remains resistance to water, adhesive strength, solid content and
A difficult problem for bin stability etc..The wood-based plate technological development aspect that starch adhesive is applied also also has a lot of difficulty needs gram
Clothes.
[summary of the invention]
The present invention provides a kind of environment friendly artificial board, to solve that current straw-based panel material mechanical strength is relatively low, to be difficult to
