Footpath wood, fast-growing thinnings etc., such as Eucalyptus, Lignum seu Ramulus Cunninghamiae Lanceolatae, poplar thinnings etc., wide material sources, its resin uses MDI(diphenyl methane
Diisocyanate) glue and without formaldehyde, it is ensured that the environmental-protecting performance of OSB plate.Fiber-reinforced resin matrix compound material FRP plate uses
Food level resin.And the primary raw material of the main material glass fibre used by the present invention is: quartz sand, aluminium oxide and pyrophyllite,
Limestone, dolomite, boric acid, soda, Natrii Sulfas, fluorite etc., the most no matter from raw material sources and serviceability, the present invention answers
Closing the floor feature of environmental protection is all that former technique is incomparable.And surfacing polyurethane (urea) elastomer used and substrate and FRP face
Adhesive for polyurethane, OSB plate used between flaggy are all the environment-friendly materials generally acknowledged in the world.
Three, processability: the processing characteristics that the preparation method of the present invention is excellent is mainly reflected in that wooden substrate is compound, FRP plate
Three aspects such as preparation and surface process.
Wooden substrate aspect: drastically reduce the area the compound number of plies on floor, if it is for container bottom board, by originally
21 layers be kept to 3～10 layers, greatly reducing cloth glue-line number, and complete pile line operation can be carried out according to practical situation, raw
Producing efficiency is an important breakthrough.
FRP plate aspect: use ripe continuous composite material panel production line streamline to be made.
3. polyurethane (urea) elastomer spraying aspect: use the solvent-free spraying technology of high pressure, assembly line work, skill can be realized
Art advanced person, quick solidifying, simple to operate.
Said process all can realize production line balance operation, efficiently solves production efficiency, reduces labor intensity, minimizing people
The problems such as power cost.
Four, surface property: the composite floor board of present invention surface the most thereon uses FRP plate or spraying polyurethane
(urea) elastomer, hasThe performances such as excellent waterproof, fire prevention, anti-skidding, wear-resisting, corrosion-resistant, shock resistance, product surface is non-parent
Oily matter, has excellent self-cleaning function, and will not become corruption by raw bacterium；Shades of colour, and face can be adjusted according to customer requirement
Colour-stable good.Raw material environmental protection, preparation method environmental protection, the release of product contamination-free；Excellent MOR and springform
Amount；5. surface coating polyurethane has response speed soon, and gel time is short, sprayed coating seamless, non skid matting self-assembling formation, also
There is the physical and chemical performance of excellence.

Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the present invention is given elaboration further.
The composite floor of the present invention include mutually glued substrate and be arranged at this upper surface of base plate, lower surface at least it
Panel layer on one.Wherein, substrate is formed by hot pressing after directive construction OSB plate and veneer assembly.Determining used by the present invention
To structure OSB plate, it is also called " oriented wood chipboard (Oriented Strandboard, OSB are called for short OSB) ", domestic referred to as Europe
Deals.It is to use drying, screening, applies adhesive and the flat long narrow wood shavings of additive, be oriented hot pressing after mating formation and form
A kind of structural panel.Owing to being the most cross-laminated together, so having the highest intensity by many wood chips.Material used by it
Material is soft pin, the undersized log of broad-leaved wood, fast-growing thinnings etc., in poplar, Masson Pine, hardwood, soft weedtree and brush wood thereof
One or more be prepared from, general thickness is 8～25mm, and density is 0.65g/cm3Left and right.And veneer be Wooden veneer or
At least one in Fiber prepreg or fiber felt.Wherein, Wooden veneer uses has the one in FSC Forest Certification timber,
Such as poplar, Zelkova schneideriana Hand.-Mazz. etc., veneer thickness is 0.8～2mm.
In the composition of substrate, at least including one layer of directive construction OSB plate and at least one of which veneer, ply is several according to tool
Depending on body needs.When substrate includes at least two-layer directive construction OSB plate, can set between adjacent two-layer directive construction OSB plate
Being equipped with rift grain Wooden veneer, band Wooden veneer, Fiber prepreg or the one of fiber felt, the surface layer of substrate and bottom are then
Rift grain Wooden veneer.
And panel layer uses following two structure.
The first: panel layer is arranged on upper surface of base plate or lower surface, or arranges in upper and lower surface simultaneously.Panel
Layer is fiber-reinforced resin matrix compound material FRP plate, fiber-reinforced resin matrix compound material FRP (Fiber Reinforced
Plastics) i.e. fiber-reinforced plastic, is to be used continuous composite material sheet material system by continuous fiber, chopped mat and food level resin
Standby technique is made, and continuous fiber warp-knitting unidirectional or multiaxial fabric are made, and continuous fiber used is glass fibre, carbon fiber, aramid fiber
At least one in fiber or other artificial or synthetic fibers, its fiber quality content is 40～70%, and thickness is 0.5～2mm.
Fiber uses plain and the fiber felt of 200g/m2 of 450g/m2.
In existing composite floor board, the bonding problem between substrate with panel layer interface always hinders its overall performance to improve
Key factor, due to both self different thermal coefficient of expansions and chemical reaction characteristic, the topmost destruction shape when stress
Formula is layered exactly, and particularly two kinds of unlike materials of FRP plate and wood materials carry out bonding compound.And the composite floor board of the present invention
Using dual-component polyurethane adhesive mutually glued between substrate with FRP plate, adhesive coated weight is 300～800g/m2, this pair of group
Segregation urethane operable time can be adjusted according to process requirements, has good adhesive property, and its machine with FRP plate and timber
Tool intensity is big, ageing-resistant, weatherability strong, good springiness, has excellent recovery Memorability, service life when bearing dynamic load
Up to 15～20 years, solve the bonding problem between substrate with panel layer interface.
The second: panel layer is arranged on upper surface of base plate or lower surface, or arranges in upper and lower surface simultaneously.Then
Above, the upper surface of flaggy sprays one layer of polyurethane (urea) elastomer with high abrasion, decay resistance again, the most right
Claiming the floor of structure when effect loaded, upper surface/lower surface provides powerful anti-impact force, compressive stress, lower surface/upper table
Face provides powerful tension, can play that reinforcing fiber is high-strength, the performance of Gao Mo to greatest extent, becomes resisting the bending on floor
Shape, effectively makes up the deficiency of OSB plate mechanical property.
It addition, as shown in Figure 6, at surface layer or the bottom of substrate, or simultaneously at surface layer and bottom along himself wood grain side
Upwards (as shown by arrows in FIG.) offering multiple notch 20, the cross sectional shape of notch 20 can be semicircle or square, institute in figure
Showing is 1～3mm for semicircle, the radius of notch 20 or width, and groove depth is 0.5～3mm, the adjacent spacing between two notches
Being 20～50mm for L, the length of notch 20 can be identical with the length of substrate.So be conducive to increasing adhesive and substrate surface
Bond area and mutual grasp, improve adhesive strength.
