Description
Technical field
The present invention relates to the preparation methods of the hollow Wood-plastic floor of flame retardant type.
Background technique
Wood-plastic floor have it is water-fast, corrosion-resistant, not easy to crack, be not easy hygroscopic deformation, good stability of the dimension, without free formaldehyde
The advantages that release, is a kind of environmentally friendly pavement, can be widely applied to the building floor file field of indoor and outdoor.At present this
Kind floor mostly uses plastic buckle that Wood-plastic floor is fixed on the keel for supporting Wood-plastic floor, or is equipped on Wood-plastic floor
The slot of Wood-plastic floor bottom surface is inserted on preset sliding rail buckle when installation by slot；Or two sides of Wood-plastic floor have it is convex
Fin, is embedded into groove by rib and groove during installation, but due to not having latching function, it is still desirable to which screw is fixed in
Generate sliding on keel or ground under external force to avoid floor.Existing Wood-plastic floor purposes is single simultaneously, Zhi Nengman
The specific occasion of foot needs, and the structure of such as indoor Wood-plastic floor is not able to satisfy the functional requirement of leaking water of outdoor wood plastic floor, and
The structure of outdoor wood plastic floor is not able to satisfy the seamless spliced requirement of indoor Wood-plastic floor again, have a single function, install complexity and at
This height.If used as indoor pavement, common Wood-plastic floor does not have anti-flammability, and there are huge fire safety evaluating hidden danger.
Entitled " a kind of preparation method of fire-retardant polyolefin based wood plastic composite material " (China Patent No.:
ZL2011110215654.2, the applying date: on July 9th, 2011): it discloses using 8~30 parts of nanometer inorganic flame retardants to polyene
Alkyl wood plastic composite carries out flame retardant treatment, has excellent smoke suppressing, good anti-flammability and mechanical property, but fire-retardant
The high expensive of agent；Entitled " flame retardant high-wood content wood-plastic composite material and preparation method thereof " (China Patent No.:
ZL201110208027.6, the applying date: on July 25th, 2011) it discloses one kind wood fibre is respectively adopted with fire retardant and include
Guanylurea phosphate, flame-retardant direction, methylolation guanylurea phosphate, ammonium polyphosphate, ammonium pyrophosphate, one hydrogen amine of phosphoric acid, biphosphate
Amine, ammonium sulfate, melamine or melamine pyrophosphate, but need to include that high polymerization degree is poly- with the flame retardant for plastic
The preferably fire-retardant work of competence exertion is used in combination in ammonium phosphate, red phosphorus, expansible graphite, melamine cyanurate or phosphate
With；Entitled " flame-retardant wood-plastic composite and preparation method thereof " (China Patent No.: ZL200910072237.X, the applying date:
On June 10th, 2009) patent in disclose used in fire retardant be with melamine pyrophosphate salt or polyphosphoric acid melamine
Based on salt, carbon forming agent is helped supplemented by starch, the expansion type flame-retarding body that 4A molecular sieve is synergist, zinc borate is smoke suppressant composition
System, needs fire retardant additive amount larger, flame retarding efficiency is not high.On the whole, the prior art has fire retardant additive amount big, cost
Higher, flame retarding efficiency is low.
Summary of the invention
The present invention will solve that existing Wood-plastic floor purposes is single, is laid with that cumbersome, connection is complicated, installation cost is high, has a single function,
And fire retardant additive amount is big, high expensive, the low disadvantage of flame retarding efficiency, and a kind of band is provided and is snapped connection, while in flame retardant type
The preparation method of empty Wood-plastic floor.
The preparation method for the hollow Wood-plastic floor of flame retardant type that a kind of band of the invention snaps connection is to sequentially include the following steps:
One, 50 parts~70 parts are weighed through fire retardant treated dry lignocellulosic material, 30 parts~50 by mass fraction

At low cost, which, which can be used to interior, can be used for outdoor, and additional connector, function are not needed without keel yet
Design more rationally science, have many advantages, such as it is at low cost, it is easy for installation flexible.Present embodiment passes through floor unit ontology 1
The special construction of upper and lower two tenons constructs, the size and location relationship of considered critical radian tenon 7 and plano-concave tenon 10, so that this hair
The floor unit ontology 1 of bright design is buckle without floor integral thickness, and the intermediate of upper and lower tenon forms cavity, solve cost
While high, still there is excellent connection effect.
1, it is locked between two groups of floor unit ontologies 1 using radian tenon 7, plano-convex tenon 8, radian blind mortise 9, plano-concave tenon 10
Button splicing, the radian tenon 7 and radian blind mortise 9 are arranged in pairs or groups, and left and right mutually hooks, and make the more difficult shifting of two groups of floor unit ontologies 1 or so
It is dynamic, and the floor unit ontology 1 with cambered blind mortise 9 pushes down the floor unit 1 with radian tenon 7 using gravity, thus
Keep about the 1 floor unit ontology with cambered tenon 7 immovable.
2, the radian tenon 7 is equipped with protrusion 7-1, can also even if floor unit ontology 1 is made to generate expansion or shrinkage
Stronger frictional force is formed with the radian blind mortise 9 of another floor unit ontology 1, increases its stability.
3, the plano-convex tenon 8 and plano-concave tenon 10 are arranged in pairs or groups, and the floor unit ontology 1 with plano-concave tenon 10 is pushed down using gravity
Floor unit ontology 1 with plano-convex tenon 8, to keep about 1 floor unit with plano-convex tenon 8 immovable.
4, the radian tenon 7 and plano-concave tenon 10 are in the same side of floor unit 1, and plano-convex tenon 8 and radian blind mortise 9
In 1 other side of floor unit, to make mutually hook by left and right between two floor units 1, mutually be pressed up and down to remain steady
Gu.
5, plano-concave tenon 10 is wide along floor unit ontology 1 less than plano-convex tenon 8 along the size of 1 width direction of floor unit ontology
The size in direction is spent, therefore, forms cavity between two floor unit ontologies 1 when installation, when reserving floor tilt rotation card slot
The space needed, otherwise floor tilt cannot achieve buckle installation.
6, there is sufficient space that can accommodate power supply line, cable, cable etc. in cavity 2, and there are enough reserved spaces to guarantee that it is logical
Wind heat dissipation, chamfer design can protect cable, will not form physical injury to cable.
7,1 upper surface 3 of present embodiment floor unit ontology is equipped with embossing, can increase rubbing between sole and floor
Wipe, and it is imitative have solid wood lines, so that floor is had more woodiness touch.
8, floor unit ontology 1 lower surface 4 is equipped with drain groove 5, is designed using notch, can increase floor on the ground
Stability, while reserved internal expansion space, reduction linear expansion coefficient, and the ponding on ground can be enable timely under floor
It flows away, meets indoor and outdoor drainage requirement.
9,1 lower surface 4 of floor unit ontology is equipped with non-slip groove 6, it is possible to increase the frictional force between original ground and floor makes ground
Plate unit ontology 1 and ground are without sliding；And when there is small grains of sand dust on ground, small grains of sand dust can fall into the recess of non-slip groove 6
Position, to guarantee the regularity of the floor entirety upper surface after being laid with.
