Description
Technical field
The utility model relates to a kind of Wood-plastic floor, has related in particular to a kind of circular hole co-extrusion fire retardant polyolefin Wood-plastic floor.
Background technology
Can produce multi-component composite product by several different methods, adopting coextrusion processes is a kind of the most simple and easy to do method.It has become one of contemporary state-of-the-art plastics processing method.High gathering without coextrusion processes is that a kind of book platform extruder that uses is supplied with respectively different melting charge stream, amounts to and extrudes the process that obtains multilayer composite product at a composite machine head internal exchange.The material that it can make multilayer have different qualities is combined with each other in extrusion, make goods have the good characteristic of concentrating different materials, in characteristic, carry out complementation, thereby obtain performance and the outward appearance of particular/special requirement, as anti-oxygen and damp proof obstructing capacity, coloring, heat insulating ability, thermoforming and heat bonding ability, and the mechanical performance such as intensity, rigidity, hardness.These multilayer materials with combination property have using value extremely widely in a lot of fields.In addition, it can significantly reduce goods cost, simple flow, minimizing equipment investment, recombination process without solvent, do not produce three wastes material.
Along with reclaim taking waste and old material and comprehensive utilization of resources as the economic trend of core, utilize waste or used plastics and wood fiber production Wood-plastic profiles to comply with this trend.Wood-plastic profiles is widely applied in architectural decoration material field, particularly gets most of the attention towards the development of co-extrusion direction, but also has its shortcoming and defect, wherein relates to the fire resistance aspect of wood plastic composite.In sum, in order to expand the application of wood-plastic co-extrusion material, improve the fire safety performance of wood-plastic co-extrusion material, wood-plastic co-extrusion material is carried out to flame treatment, prepare flame-retardant wood-plastic co-extrusion section bar.
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 little in the utility model, a kind of circular hole co-extrusion fire retardant polyolefin 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 circular hole co-extrusion fire retardant polyolefin Wood-plastic floor, tabular core body, core body cross section parallelogram, core body, the center of side is equipped with draw-in groove, and the angle of core body side and horizontal plane is 50 °～60 °; Core body upper surface is provided with " ten " font guiding gutter, and it is semi-circular recesses that core body soffit is provided with 4～6 cross sections, and groove two ends are respectively through core body both ends of the surface; It is manhole that core body middle part is provided with 4～6 cross sections, and groove is parallel with the axis of through hole; Core surface is coated with fire-retardant skin, and fire-retardant outer field thickness is 0.8mm.
Core body cross section parallelogram, core body is cuboid, this makes the utility model in the time laying, between adjacent two, clinching closely together, after laying, be difficult for prizing, can ensure the more stable of these floor covering layers, increase its application life.The center of core body side is equipped with draw-in groove, and draw-in groove is convenient to installing and using of floor, can not only improve efficiency of construction, also can further increase the stability after install on floor.Core body upper surface is provided with " ten " font guiding gutter, it is semi-circular recesses that core body soffit is provided with 4～6 cross sections, guiding gutter can be drained to the gap location between floor and floor by the liquid liquid of floor surface, thereby make the floor surface can ponding, avoided the inconvenience bringing to pedestrian because of ponding.The design of soffit semi-circular recesses can increase floor surface friction, produces skidproof effect; Because be still plane between every two grooves, so can ensure the planeness of ground slab integral; And groove can also play good supporting role to whole tabular core body, improve the significantly floor intensity of size, and can play good protection against the tide, water-proof function to floor, make it not only can be for indoor furniture, can also be used for open air, greatly expand the range of application of wood plastic composite; Used time, the form that floor soffit adopts this concave surface and plane to be alternately formed by connecting, can realize the front function of the rough ground of laying in advance of laying floor, adopt this kind of floor, without being set, rough ground still can ensure that floor is smooth, more convenient compared to the installation of plane general floorings, use more economical.Core body middle part is provided with the manhole of evenly arranging, hollow structure has reduced materials'use, and in use can be in this circular hole patchhole post, can play good supporting role to whole tabular core body, improve the significantly section bar intensity of size, while using out of doors constructional materials simultaneously, this circular hole can play a role in the drainage, so circular hole is set at wood-plastic co-extrusion section bar core body middle part and can have greatly expanded 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.Core surface is coated with fire-retardant skin, and the thickness of flame-retardant layer is 0.8mm, and floor surface is carried out to flame treatment, then prepares flame-retardant wood-plastic co-extrusion section bar, thereby improves 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.
As preferably, the width of guiding gutter is 2mm.This is of a size of the optimum size of guiding gutter, because guiding gutter width can cause guiding gutter easily to stop up lower than 2mm, guiding gutter width can affect practicality and the sight on floor during higher than 2mm.
As preferably, draw-in groove sidewall is connected by arc transition with core body side.Arc transition connects can avoid stress to concentrate and the damage that causes, and can effectively reduce wood-plastic co-extrusion section bar and use out of doors time, body refuse, accumulation of mud, be difficult to cleaning simultaneously.
The utility model, owing to having adopted above technical scheme, has significant technique effect:
The utility model carries out flame treatment to skin, prepare flame-retardant wood-plastic co-extrusion section bar, the circular support hole design of its hollow, both reduced the use amount of material, both artistic and practical again, core body is cuboid, and between adjacent two floors, clinching closely together, increases the stability of floor covering layers.The design of draw-in groove makes more convenient and quicker in work progress, improves efficiency of construction, and the utility model has been expanded the range of application of wood plastic composite greatly, is allowed to condition at outdoor building landscape design practical application aspect and upgrades to a new height.
