Description
【Technical field】
The invention belongs to wood-based plate preparing technical fields, and in particular to a kind of wood-based plate and preparation method thereof.
【Background technology】
China is large agricultural country, produces agricultural crop straw per year at 800,000,000 tons or so, these a large amount of agricultural crop straws are traditional
Processing mode is on-site incineration or heap to be allowed to degenerate, and causes the problem of environmental pollution is serious etc. in this way.
Currently, in terms of using agricultural crop straw processing artificial boards material, China achieves larger breakthrough.But it is existing
Simple straw-based panel, since content of lignin is relatively low in agricultural crop straw raw material, with the medium-density plate of its production
Material mechanical strength is relatively low, and nail-holding ability is smaller.Simple straw-based panel, due to the wax content in agricultural crop straw compared with
Height is not easy gum forming.
How to solve the problems, such as that current straw-based panel material mechanical strength is relatively low, be not easy gum forming, is ability
Field technique personnel's urgent problem to be solved.
Since the 21th century, domestic wood-based panel industry obtains unconventional fast development, increases by 22% every year, 2009
Wood-based plate yield is more than ten thousand stere more than 8000, year consumes adhesive about 5,000,000, becomes the first big country of world's Wood-based Panel Production.
Currently, wood-based plate manufacturing uses both at home and abroad adhesive main still Lauxite, phenolic resin, melamino-formaldehyde tree
Fat etc..Free formaldehyde content is higher in the adhesive of this type, toxic formaldehyde gas is slowly released during use, to human body
It damages.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.Such as add urea, melamine fomol catcher；Another party
Face attempts to inexpensive biomass poly hydroxyl compound and prepares adhesive for raw material to replace formaldehyde system adhesive.It is being reported
Above-mentioned thinking in, the cost of starch-based adhesive is relatively low, is a kind of natural poly hydroxyl compound material for most having application prospect.
The national conditions of corrugated board packing box are widely used in conjunction with domestic starch adhesive, starch adhesive forms sediment by new structure
The MOLECULE DESIGN of powder and graft copolymerization after control oxidative cleavage, crosslinking, solve adhesion strength and water resistance, are used for industry of artificial boards
It is economically feasible.Over the past two years, there are the exploratory development or invention of part wood-based plate starch adhesive
Patent.But from the point of view of result of study starch-based adhesive be used for wood-based plate, however it remains water resistance, adhesive strength, solid content and
The problem of bin stability etc..Also there are many difficult needs gram in terms of the technological development that wood-based plate is applied with starch adhesive
Clothes.
