Description
Technical field
The utility model relates to a kind of wood-plastic co-extrusion section bar, has related in particular to a kind of flame-retardant wood-plastic co-extrusion section bar.
Background technology
Mould wood and be that to take the low value biomass fibers such as sawdust, wood chip, bamboo bits, rice husk, wheat straw, soybean skin, peanut shell, bagasse, cotton stalk be main material, a kind of composite material synthetic with plastics.It possesses the advantage of string and plastics simultaneously, applied widely, the use field that almost can contain all logs, plastics, plastic-steel, aluminium alloys and other similar composite material, has simultaneously also solved 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.
Along with take the economic trend that waste and old material reclaims and comprehensive utilization of resources is core, utilize waste or used plastics and wood fiber to produce Wood-plastic profiles and complied with this trend.Although Wood-plastic profiles is widely applied in architectural decoration material field, particularly the development towards co-extrusion direction gets most of the attention, and also has its shortcoming and defect, and 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 co-extrusion section bar is provided.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A flame-retardant wood-plastic co-extrusion section bar, comprises core body, and core body is symmetrical platy structure, and core body upper surface is horizontal plane, and soffit middle part is horizontal plane, and soffit two ends are acclivitous inclined-plane, and inclined-plane and horizontal plane angle are 20 °～30 °; Inclined-plane can facilitate the installation on floor, floor is installed more firm, and can play certain moisture-proof role; 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 quantity of square hole and the length of side all can arrange according to the practical application of wood-plastic co-extrusion section bar, the centre position at core body two ends is equipped with draw-in groove, draw-in groove comprises upper horizontal plane, vertical plane and lower horizontal plane, the length of upper horizontal plane is greater than the length of lower horizontal plane, draw-in groove is the groove shape structure that upper horizontal plane, vertical plane and lower horizontal plane are connected in sequence, draw-in groove opening is back to core body center, and draw-in groove width is 25～30mm.
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 the waste of cost of production again; 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, improved the significantly section bar intensity of size, while using out of doors constructional materials simultaneously, this square hole can play a role in the drainage, so the range of application that square hole can have been expanded wood plastic composite is greatly set at wood-plastic co-extrusion section bar core body middle part, be allowed to condition at outdoor building material, indoor furniture practical application aspect upgrades to a new height.At core body two ends, type draw-in groove is set, draw-in groove can play firm effect in use to Wood-plastic profiles, then prevents that section bar from departing from work plane, and the structure of draw-in groove is designed to upper horizontal plane and is greater than lower horizontal form, can increase the active force of draw-in groove, strengthen the stability of core body.
As preferably, square hole is square hole, 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 in the time of effectively reducing wood-plastic co-extrusion section bar and use out of doors, body refuse, accumulation of mud, be difficult to cleaning simultaneously.
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 co-extrusion section bar surface, improved the fire safety performance of wood plastic composite, and square hole in the middle of Wood-plastic profiles middle part arranges, both can conveniently to whole section bar core body, play support reinforcing effect, play a role in the drainage during architectural use out of doors again, greatly expand the range of application of wood plastic composite, be allowed to condition at outdoor building material, indoor furniture practical application aspect upgrades to a new height.
