Therefore, how to provide a kind of lawn protection material simple in structure, easy-to-dismount to become the problem that industry need to solve.
Summary of the invention
One of purpose of the present invention provides a kind of lawn protection material simple in structure, easy-to-dismount.
Another object of the present invention provides the manufacture method of this lawn protection material.
On the one hand, to achieve these goals, the invention provides a kind of lawn protection material, it comprises woven base material and cast layer; Wherein, the woven base material flat filament braiding of producing with the flat filament raw material that comprises the first high polymer forms; Cast layer forms with the coating raw material that comprises the second high polymer and blowing agent; Cast layer is coated on the woven base material, and itself and woven base material are compound; Cast layer is membrana perforata, which is provided with a plurality of perforation that foaming forms.
Among the present invention, the width of flat filament is controlled at that 1.5-3.5 millimeter, line density are controlled at the 800-2000 Denier, single pulling force is not less than 38 newton.
Among the present invention, the fabric width of woven base material is approximately 4-6 rice, certainly, also can be the size that other needs.
Among the present invention, the first high polymer can be multiple material of the prior art, such as high density polyethylene (HDPE) (HDPE), dacron thread, polyamide fibre (nylon) silk etc.Because the function admirable such as polythene material acid and alkali-resistance, cost performance are high; And high density polyethylene (HDPE) is fit to wire drawing, and intensity is high, thereby the first high polymer is preferably high density polyethylene (HDPE).
Because the fabric width of woven base material is wider, the second high polymer that is used for the making cast layer among the present invention should be selected the material that the curtain coating performance is good, film forming is good, suitable curtain coating applies, such as high density polyethylene (HDPE) (LDPE), ethylene-vinyl acetate copolymer (EVA) etc.Because high density polyethylene and low density polyethylene belong to polyethylene together, the same substance adhesive property is good, and peel strength is high, thereby the first high polymer and the second high polymer are preferably high density polyethylene and low density polyethylene.
Among the present invention, the effect of casting films is the anchoring fabricbase, and fixedly the flat filament in the woven base material does not make it move exactly.Because woven base material is weaved cotton cloth for dredging, the flat filament in the woven base material can easily produce movement up and down and be out of shape under certain external power effect, even running, applies the such casting films of one deck and just play the fixedly effect of fabricbase in woven base material.
Among the present invention, a plurality of perforation on the casting films make casting films form " the mashed film " of fishing net shaped, make product have the hydrophobic, air-permeability function, simultaneously the intensity of integral body are also had contribution.
The present invention is with the form of composite plastic woven, and drop cloth is protected on the production meadow, and product strength is high, attractive in appearance, anti-aging is effective, easy to use, easy disassembling, but Reusability, cost is low, and cost performance is high; Wherein, the woven base material layer provides the product strength support; The membrana perforata of cast layer (mashed film) is fixed the flat filament of woven base material, and product has the hydrophobic, air-permeability function, intensity is high, ageing-resistant.
Another embodiment according to the present invention, the first high polymer are high density polyethylene (HDPE), and the second high polymer is low density polyethylene (LDPE).
In order to produce upper better control, product is larger through the density ratio weft density usually.Another embodiment according to the present invention, woven base material be 20-32 root/10 centimetre through density, 22-32 root/10 centimetre more preferably on this basis, weft density is 18-22 root/10 centimetre.
Another embodiment according to the present invention, the weight of lawn protection material are 60-220g/m 2
Another embodiment according to the present invention, the warp tensile strength of lawn protection material are not less than 400 newton/5 centimetre, and weft tensile strength is not less than 350 newton/5 centimetre.
Another embodiment according to the present invention also comprises the calcium carbonate of 2-5%, the light stabilizer of 10-30ppm in the flat filament raw material.Wherein, calcium carbonate can reduce cost, also plays anti-tear effect, prevents that namely the flat filament that pulls out from fluffing, and can also reduce the percent thermal shrinkage of flat filament, strengthens the dimensional stability of product etc.
Another embodiment according to the present invention applies the blowing agent that comprises 0.5-2.5% in the raw material, and this blowing agent is that Celogen Az and talcum powder are composite in the 1:1 ratio; Apply in the raw material and also comprise the colouring agent of 2-5%, the light stabilizer of 10-30ppm.Wherein, colouring agent is preferably for example green mother of green colourant.In addition, also can add a small amount of White Mineral Oil.
Another embodiment according to the present invention, light stabilizer are hindered amine, such as the FD944 of BASF AG.
On the other hand, the invention provides the method for the manufacture of above-mentioned lawn protection material, it comprises the steps:
(1) preparation comprises the flat filament raw material of high density polyethylene (HDPE), and makes flat filament with this flat filament raw material;
(2) flat filament of making take step (1) weaves as material, makes woven base material;
(3) prepare to comprise the coating raw material of low density polyethylene (LDPE), blowing agent, will apply raw materials melt after curtain coating to woven base material; Under the effect of blowing agent, form membrana perforata at woven base material.
In the step (1), the method for producing flat filament specifically can be, and for example, then the flat filament raw material cuts itemize through the screw extruder film forming, after drawn, the typing, is wound into an ingot.
In the step (2), can there be shuttle Plain loom or circular weaving machine to weave, to make woven base material.
In the step (3), the concrete mode of curtain coating is, for example, with screw extruder the material blends such as LDPE is extruded into film, then by compounding machine with film " applying " above woven base material.Its processing temperature is controlled at 260-310 ° of C.The casting films thickness that forms is substantially at 20-50 ± 5g/m 2
Said method is preferably, and the flat filament width of manufacturing is that 1.5-3.5 millimeter, line density are that 800-2000 Denier, single pulling force are not less than 38 newton in the step (1).
In addition, product can be widened by sewing, to be fit to various places specification, can play along the limit sail circle after widening.
Compared with prior art, the present invention possesses following beneficial effect:
The present invention is with the form of composite plastic woven, and drop cloth is protected on the production meadow, and product strength is high, attractive in appearance, anti-aging is effective, easy to use, easy disassembling, but Reusability, cost is low, and cost performance is high; Wherein, the woven base material layer provides the product strength support; The cast layer of fishing net shaped is fixed the flat filament of woven base material, and product has the hydrophobic, air-permeability function, intensity is high, ageing-resistant.
