Description
Technical field
The utility model relates to a kind of Wood-plastic floor, has related in particular to a kind of flame-retardant wood-plastic floor.
Background technology
Moulding wood is taking low value biomass fibers such as sawdust, wood chip, bamboo bits, rice husk, wheat straw, soybean skin, peanut shell, bagasse, cotton stalks as main material, a kind of composite material synthetic with plastics.It possesses the advantage of string and plastics simultaneously, applied widely, almost can contain the use field of all logs, plastics, plastic-steel, aluminium alloys and other similar composite material, simultaneously also solve the regeneration problem of plastics, wood industry waste resource.Its main feature is: raw material resources, product plasticization, use environmental protection, cost economization, reclaiming.
Mould by certain specification becomes various forms of section bars to be plastic-wood section plastic-wood material extrusion, and the floor making by Wood-plastic profiles is Wood-plastic floor.Although along with reclaim taking waste and old material and comprehensive utilization of resources as the economic trend of core, Wood-plastic profiles is widely applied in architectural decoration material field, particularly get most of the attention towards the development of co-extrusion direction, but also have its shortcoming and defect, as wood plastic composite exists, fire resistance is poor, the scope of application is narrower etc.So, in order to expand the application of wood-plastic co-extrusion material, improving fire safety performance and the range of application of wood-plastic co-extrusion material, need improve wood-plastic co-extrusion material.
Summary of the invention
There is for wood-plastic co-extrusion material in prior art the problem that fire resistance is poor, the scope of application is narrower in the utility model, a kind of flame-retardant wood-plastic floor is provided.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of flame-retardant wood-plastic floor, comprises core body, and core body is symmetrical cuboid platy structure, and core body upper surface is the flank of tooth that is provided with rectangular teeth, and the spacing between every two rectangular teeths is 5mm, between rectangular teeth, connects by arc transition; Core body skin is coated with flame-retardant layer, the thickness of flame-retardant layer is 1～3mm, on core body, be provided with 3～5 square holes of evenly arranging, the centre position at core body two ends is equipped with draw-in groove, draw-in groove is " U " type, " U " type draw-in groove opening core body center dorsad, and draw-in groove comprises upper horizontal plane, vertical plane and lower horizontal plane, upper horizontal plane length equals lower horizontal plane length, and the ratio of upper horizontal plane length and vertical plane height is 3:1.
By at the outer coated one deck flame-retardant layer of core body, skin is carried out to flame treatment, then prepare flame-retardant wood-plastic co-extrusion section bar, thereby improve the flame-retarding performance of wood plastic composite.Wherein the thickness of flame-retardant layer can, because of the too small flame retardant effect that affects of flame-retardant layer thickness, can not cause because thickness is excessive again the waste of cost of production; Core body upper surface is the flank of tooth that is provided with rectangular teeth, and spacing between every two rectangular teeths is 5mm, between rectangular teeth, connects by arc transition, adopt such increment face can ensure the integral smoothness of floor surface, can increase again floor surface friction, produce skidproof effect; Core body middle part is provided with the square hole of evenly arranging, hollow structure has reduced materials'use, and in use can be at this square hole interpolation hand-hole post, can play good supporting role to whole tabular core body, improve the significantly floor intensity of size, while using out of doors, this square hole can play a role in the drainage simultaneously, so square hole is set at the core body middle part of Wood-plastic floor and can have greatly expanded the range of application of wood plastic composite.In addition, " U " type draw-in groove is set at core body two ends, and draw-in groove upper horizontal plane length equals lower horizontal plane length, the ratio of upper horizontal plane length and vertical plane height is that the dimension scale of this draw-in groove of 3:1 is that guarantee Wood-plastic floor is strengthened firm optimum size in use, can effectively prevent that floor from departing from work plane, strengthens Wood-plastic floor stability.
As preferably, the width of draw-in groove is 3～4mm, and the degree of depth is 10～12mm.The firm performance of the draw-in groove under this size is stronger.
As preferably, square hole is slot, and four angle points are provided with the chamfering that radius is 2～3mm.Chamfering can avoid four corner point stress to concentrate and the angle point that causes damages, and can effectively reduce wood-plastic co-extrusion floor simultaneously while using out of doors, and body refuse, accumulation of mud, be difficult to cleaning.
As preferably, the thickness of flame-retardant layer is 2mm, the optimum thickness that this thickness is flame-retardant layer.
The utility model, owing to having adopted above technical scheme, has significant technique effect:
The utility model is by being coated flame-retardant layer on Wood-plastic floor surface, improve the fire safety performance of wood plastic composite, and square hole in the middle of Wood-plastic floor middle part arranges, both can conveniently play support reinforcing effect to whole floor core body, can use out of doors again time, play a role in the drainage, greatly expanded the range of application of wood plastic composite.
