Description
Technical field
The present invention relates to a kind of wood-based plate biology base ureaformaldehyde composite materials.
Background technology
Wood-based plate is a kind of comprehensive utilization forest resourceies, and by broken wood shavings, wood fibre, wood chip, the wooden particle passes through rubber polymer
Stick passes through glue mixing, is cold-pressed, the plank that the techniques such as hot pressing are fabricated, including density board, particieboard, particle board, multi-layer board, fixed
To particieboard（OSB）Deng.Wherein common adhesive is the urea-formaldehyde glue being fabricated using formaldehyde and urea, or utilizes three
The urea-formaldehyde glue that poly cyanamid is modified.Due to the low cost of urea-formaldehyde glue, high bond strength, easily prepare the advantages that transport, world's wood-based plate
It is widely used as adhesive in industry.Since the volatilization of timber formaldehyde itself is very little, artificial board and its product are influenced
The arch-criminal of formaldehyde excess release is adhesive.The characteristic of urea-formaldehyde glue determines that it can release in production process of plate
Free formaldehyde, and reduce the content of formaldehyde in glue merely while also reducing bond strength, therefore, many plank manufacturers exist
In production, the means such as masking, absorption, closing are taken mostly, to delay the release of formaldehyde, so actually by the harm in production
It is transferred in use, not being inherently eliminated the formaldehyde hidden danger implied in plank.Once have the condition of formaldehyde volatilization, this
Part formaldehyde still can largely volatilize, and influence people's health.The release time of formaldehyde is about 15 years in wood-based plate, world health group
It knits and formaldehyde is confirmed as II class carcinogenic substances, therefore, countries in the world more carry out the standard of the release limitation of artificial board formaldehyde about tight
Lattice, for example, meeting E0 grades of plank, content of formaldehyde is necessarily less than 5mg/100g, meets E1 planks, and content of formaldehyde is necessarily less than
9mg/100g；And the artificial board for using the means such as masking, absorption, closing to produce, it is typically only capable in the burst size of formaldehyde
Reach E2 grades of standards or E1 grades of standards can be reached reluctantly.Therefore, it is badly in need of providing a kind of material that can reduce Form aldehyde release,
On the one hand it can enhance adhesive property of the urea-formaldehyde glue to wood materials, furthermore it is possible to the burst size of formaldehyde be substantially reduced, to carry
The environmental protection grade of the wood-based panel product of height urea-formaldehyde glue production.
Invention content
The purpose of the present invention is:A kind of burst size that can substantially reduce formaldehyde is provided and enhancing urea-formaldehyde glue is to wood materials
Adhesive property wood-based plate biology base ureaformaldehyde composite material.
Realizing the technical solution of the object of the invention is：A kind of wood-based plate biology base ureaformaldehyde composite material, innovative point exist
In, it is combined with biological composite reinforcing material by Lauxite or melamine urea-formaldehyde resin, in terms of solid, ureaformaldehyde tree
The weight ratio of fat or melamine urea-formaldehyde resin and biological composite reinforcing material is 2~9: 8~1；
The biology composite reinforcing material be containing 8~50wt% of protein, fat 1~10wt%, 40~89wt% of cellulose,
Surplus is the solid powder of water, and fineness is 100~200 mesh.
In above-mentioned biology base ureaformaldehyde composite material, the biology composite reinforcing material is vinasse base without the compound increasing of aldehyde biology
Strong material, mixture of the algae base without one or both of aldehyde biology composite reinforcing material.
Above-mentioned biology base ureaformaldehyde composite material, when being used for making artificial plate, in the biology base ureaformaldehyde composite material
Water is added, it is 45~65wt% to make the solid content of biology base ureaformaldehyde composite material, adds curing agent, and addition is biology
0~20wt% of base ureaformaldehyde composite material solid amount, stirs evenly, you can it is used to prepare wood-based plate by prior art, it is obtained
Its content of formaldehyde of wood-based plate meets European Union E0 and U.S. CARB Form aldehyde release limitation requirements.
Above-mentioned biology base ureaformaldehyde composite material, the wood-based plate are to be using wood materials as raw material or with agricultural crop straw
One kind in the density board of raw material, particieboard, oriented wood chipboard, multi-layer board.
The solution have the advantages that：The present invention wood-based plate in biology base ureaformaldehyde composite material be furnished with suitable biology
Composite reinforcing material, the material are containing 8~50wt% of protein, and 1~10wt% of fat, 40~89wt% of cellulose, surplus is water
Solid powder, fineness are 100~200 mesh, and this material itself is free of formaldehyde, and protein contained therein and Lauxite
Or the free formaldehyde contained by melamine urea-formaldehyde resin has binding ability.Therefore, with the biology base ureaformaldehyde composite wood of the present invention
Expect the wood-based plate made, the burst size of formaldehyde can be substantially reduced（Meet European Union E0 and CARB Form aldehyde releases limitation in the U.S.'s is wanted
It asks）And enhance adhesive property of the urea-formaldehyde glue to wood materials or agricultural crop straw（It is shown in Table 1~7）.In addition, biology used is compound
Reinforcing material itself is free of formaldehyde, and affordable, smaller to the cost impact of wood-based plate, therefore, has a vast market
Foreground.
