Abstract
The utility model belongs to board technology field, more particularly, to a kind of fire-retardant LSB plate of impregnated paper veneer.Including sandwich layer and surface layer, the sandwich layer is that big flaking orienting spreading is formed, and the surface layer is that small flaking or small fibre plate orienting spreading are formed, and fire retardant is added in sandwich layer, and the surface on surface layer is equipped with impregnated bond paper.Advantage is: fire retardant is mixed into wood fibre or other plant fiber, and flame retardant effect is better than common coating fire proofing, and product anti-flammability is in B1-C grade standard.Orienting spreading refers to mating formation flaking according to unified direction, and the skin depth obtained after mating formation is also more consistent, to solve the problems, such as surface irregularity.
Description
Technical field
The utility model belongs to board technology field, more particularly, to a kind of fire-retardant LSB plate of impregnated paper veneer.
Background technique
OSB plate is also known as oriented wood chipboard, and it is a kind of synthesized wood material that the country, which is referred to as Europe deals,.OSB plate be with small dimension wood,
Thinnings, wooden core are raw material, process the long flaking of growth by special equipment and are generally 40-100mm long, 5-20mm wide, 0.3-
0.7mm is thick, through a kind of oriented structure plate made of the techniques such as de-oiling, drying, sizing, orienting spreading, hot-forming.
The thickness stability of existing OSB plate is poor, is primarily due to differing in size for wood shavings, the wood shavings side of pavement process
It is fully horizontal, uniformly to cannot be guaranteed with angle, it will form certain density gradient, compacting when can be to thickness stability
Have an impact, cause OSB product surface coarse, when processing will appear rough " hollow ", coarse surface and uneven
" hollow " be unfavorable for the processing of further veneer.
Utility model content
The purpose of this utility model is in view of the above-mentioned problems, providing that a kind of thickness stability is good, leaching with flame retarding function
The fire-retardant LSB plate of stain paper veneer.
In order to achieve the above objectives, the utility model uses following technical proposal: the fire-retardant LSB plate of this impregnated paper veneer, packet
Sandwich layer and surface layer are included, the sandwich layer is that big flaking orienting spreading is formed, and the surface layer is that small flaking or small fibre plate are fixed
It to be formed to mating formation, fire retardant is added in sandwich layer, the surface on surface layer is equipped with impregnated bond paper.
In the above-mentioned fire-retardant LSB plate of impregnated paper veneer, the fire retardant is halogen system powdery combustion inhibitor.
Compared with prior art, the advantages of this impregnated paper veneer fire-retardant LSB plate is: fire retardant is to be mixed into wooden fibre
In dimension or other plant fiber, product anti-flammability is in B1-C grade standard.Orienting spreading is referred to flaking according to unified direction
Mat formation, the skin depth obtained after mating formation is also more consistent, to solve the problems, such as surface irregularity.
Detailed description of the invention
Fig. 1 is the cross-sectional view of sandwich layer provided by the utility model.
Fig. 2 is the cross-sectional view on surface layer provided by the utility model.
Fig. 3 is the cross-sectional view of the fire-retardant LSB plate of impregnated paper veneer provided by the utility model.
In figure, sandwich layer 1, surface layer 2, big flaking 3, small flaking 4, small fiberboard 5, impregnated bond paper 6.
Specific embodiment
Embodiment
As shown in Figure 1-3, the fire-retardant LSB plate of this impregnated paper veneer, including sandwich layer 1 and surface layer 2, the sandwich layer 1 are jack plane
3 orienting spreading of piece is formed, and the surface layer 2 is that small flaking 4 or 5 orienting spreading of small fibre plate are formed, added with resistance in sandwich layer 1
Agent is fired, the surface on surface layer 2 is equipped with impregnated bond paper 6, and fire retardant is halogen system powdery combustion inhibitor.The LSB plate proposed in the application is
The upgrade version of OSB plate is the optimization to traditional OSB plate, uses isocyanates MDI as adhesive, outstanding health performance, really
Environment-protective no-smell is protected, since isocyanates MDI glue is not soluble in water, also there is good waterproof and moistureproof performance.Because of oriented structure
Characteristic, it is strong to have a surface decorations property, the strong feature of nail-holding ability.
For fire retardant using halogen system powdery combustion inhibitor as raw material, fire retardant is mixed into wood fibre or other plant fiber,
Product anti-flammability is in B1-C grade standard.
The wood shavings direction of each big flaking 3 is consistent with direction is laid with, the wood shavings of each small flaking 4 or small fibre plate 5
Direction is consistent with direction is laid with.
Flaking is dug using chipper, and when flaking is larger, then each region for being easy to appear flaking is in uneven thickness
Problem.So the application will be used as sandwich layer 1 after big 3 orienting spreading of flaking, and by 5 orienting spreading of small flaking 4 or small fibre plate
It is used as surface layer 2 afterwards, because the thickness of small flaking 4 is more uniform, 2 thickness of surface layer obtained after mating formation is also more consistent, to solve
Certainly the problem of surface irregularity.Orienting spreading refers to mating formation flaking according to unified direction.Each big flaking 3
Wood shavings direction is consistent with direction is laid with, and the wood shavings direction of each small flaking 4 or small fibre plate 5 is consistent with direction is laid with.
Wood shavings direction is consistent, and conducive to flaking in homogeneous thickness is obtained, it is consistent to be laid with direction, so that plate inner horizontal after being laid with, uniformly,
Certain density gradient is not will form, so as to avoid the unstable problem of thickness in pressing process.
Big flaking 3 with a thickness of 0.45 millimeter -0.6 millimeter, small flaking 4 or small fibre plate 5 with a thickness of 0.45 millimeter -
0.6 millimeter.Flaking is excessively thin to be easily broken, and flaking is blocked up, and the original effect for eliminating wood internal stress of Europe deals is not achieved,
The thickness of flaking is defined by the application, and flaking is uniformly mated formation.
