Description
Technical field
The present invention relates to a kind of constructional materials.
Background technology
At present; The plastics protective screening is mainly used in protection and the buffer action in the construction work; Especially barbed plastics protective screening can effectively preventing the invasion of animal, also can be used as the protection in garden, pasture, forest farm etc., have good isolation effect and vision deterrent force.
The plastic tensile mesh material has the multiple mode of production, and the employing plastic strip that has is welded into groined type or square or rectangular configuration, and the employing molten plastic rotating head that has is extruded into Web materials, carries out unidirectional again or the biaxial tension mode; The employing molten plastic that has is the moulding Web materials on reciprocal head; Unidirectional again or biaxial tension mode; Some also adopts sheet material punching formation Web materials carrying out unidirectional or the biaxial tension mode, and these materials are all playing certain protection buffer action in varying degrees.
But, find that in practical application this type material generally all relatively can only play the protection buffer action, the isolating and protecting for engineering site, garden, forest farm, garden, pasture etc. does not have good visual effect.
Summary of the invention
The invention discloses a kind of protection with plastics biaxial tension grid and manufacturing approach thereof, this biaxial tension grid has the isolating and protecting effect and has good visual effect, is good security protection material.
The net structure that protection of the present invention is formed in one with plastics biaxial tension grid, net structure comprises a plurality of hexagons and rhombus, hexagon and rhombus are alternately arranged, and the self intersection place forms node.
Protection of the present invention comprises the steps: with the manufacturing approach of plastics biaxial tension grid
The preparation plastic plate;
The hole array that this plastic plate formation rule is arranged, above-mentioned Kong Zhen is alternately formed by macropore and aperture, macropore diameter is about the twice of small aperture, each hole be shaped as cross, and the distance between each hole is equal;
Four apertures are wherein arranged around each macropore, around each aperture four macropores are arranged, replace each other up and down, the distance between each adjacent hole is equated, form a new hole array;
Through longitudinal stretching, cross directional stretch, perhaps portraitlandscape synchro-draw simultaneously comprises a plurality of hexagons and rhombus thereby form, and hexagon and rhombus are alternately arranged, and the protection that the self intersection place forms node is with plastics biaxial tension grid.
Wherein, the thickness range of plastic plate is preferably 1-20mm; The pore diameter range in hole is preferably 1-50mm on the sheet material.Before stretching sheet material is preheated to the 60-120 degree; The stretching ratio of plastic plate is preferably 6-10.
The specific embodiment
In order to make the object of the invention, technical scheme and advantage clearer, pass through the specific embodiment below to the technical scheme further explain of protection of the present invention with plastics biaxial tension grid and manufacturing approach thereof.
As shown in Figure 1, protection of the present invention is with plastics biaxial tension grid, and the net structure that it is formed in one, net structure comprise a plurality of hexagons and rhombus, and hexagon and rhombus are alternately arranged, and the self intersection place forms node.
Protection disclosed by the invention comprises the steps: with the manufacturing approach of plastics biaxial tension grid
The preparation plastic plate;
The hole array that this plastic plate formation rule is arranged, as shown in Figure 2, the hole array that preferably adopts punching mode formation rule to arrange also can mold the sheet material with hole array through other extrusion ways on sheet material.
In the array of hole each hole be shaped as cross, and the distance between each hole equates;
Through longitudinal stretching, cross directional stretch, perhaps portraitlandscape synchro-draw simultaneously comprises a plurality of hexagons and rhombus thereby form, and hexagon and rhombus are alternately arranged, and the protection that the self intersection place forms node is with plastics biaxial tension grid.
The thickness range of plastic plate is preferably 1-20mm; The pore diameter range in hole is preferably 1-50mm on the sheet material.
The stretching ratio of sheet material is looked the material difference and different, and its stretching ratio was generally at 6-12 times when sheet material was polypropylene, and its stretching ratio generally at 4-10 doubly when sheet material was polyvinyl.The stretching ratio basically identical of longitudinal and transverse two directions wherein; Stretching ratio on the direction that perhaps at first stretches; For example vertically bigger, lax resilience is to a certain degree arranged when carrying out cross directional stretch, thereby form protection as shown in Figure 1 with plastics biaxial tension grid.
According to foregoing description, the array towards well-regulated hole perhaps molds the sheet material with hole disclosed by the invention array through other extrusion ways, through multiplying power such as strict vertically, cross directional stretch, formed mesh material like Fig. 1.The protective screening of this structure both can play isolating and protecting, owing to have good visual effect, was good security protection material.
Embodiment 1:
The preparation polypropylene board; Particularly, select for use the high density poly propylene polymer, add auxiliary agents such as carbon black, UV resistant agent, antioxidant as raw material; After fully mixing; Automatically gone up with vacuum feeder, melted polymer at 180-280 ℃ with extruder, and through coat-hanger die extrusion board blank; Be shaped into sheet material through three-roller calendar cooling, press polish, cut unnecessary limit; Sheet metal thickness is 5mm;
The hole array of arranging through the punching formation rule with punch press at this plastic plate.Wherein, the aperture of macropore is 6mm, and the aperture of aperture is 3mm, and the spacing between macropore and the aperture is 5mm;
This sheet material is through vertically, laterally about one by one 8-12 forms barbed biaxial tension plastics protective screening after doubly etc. multiplying power stretches.Particularly, above-mentioned sheet material is preheating to 100 ℃, carries out longitudinal stretching, different according to material, stretching ratio becomes the simple tension goods to 6-12 times after the typing; Add with special fixture and hold, get into two-way preheating oven and carry out preheating, temperature is carried out cross directional stretch then at 180-280 ℃, stretching ratio to 6-12 doubly, and after the thermal finalization, become the biaxial tension grid, the back rolling of cutting edge.
Embodiment 2:
Prepare polyethylene board; Its thickness is 8mm;
At the hole array of this plastic plate through the arrangement of punching formation rule.Wherein, each hole is a cross bore, and the aperture of each cross bore is 20mm, and the spacing between the Kong Yukong is 40mm;
This sheet material forms barbed biaxial tension plastics protective screening after stretching through multiplying powers such as 4-10 times of vertical, horizontal whiles.Particularly, above-mentioned sheet material is preheating to 80 ℃, carries out vertical, horizontal 4-10 simultaneously and doubly stretch, after the thermal finalization, become the biaxial tension grid, the back rolling of cutting edge.
According to foregoing description; The sheet material of formation cross bore array described in the invention stretches through portraitlandscape and forms the biaxial tension grid; Perhaps be similar to the above-mentioned barbed plastics protective screening structural meterials that the present invention describes, difference to some extent because the stretching ratio of vertical and horizontal is different; So protection of the present invention includes but not limited to the present invention's disclosed hole array and the biaxial tension grid that produces with the method with plastics biaxial tension grid.
