Abstract

The invention discloses a full-light-shading polyolefin greenhouse curtain, the curtain is woven by film strips and PET filaments used as warp and weft, the film strip comprises a monolayer full light shading film or multilayers of the full light shading films, thickness of each monolayer full light shading film is 40-70 mum; the shading system comprises a 3000-6000 mesh inorganic light-screening agent, and the inorganic light-screening agent is a white pigment, a black pigment, a gray pigment or a silvery pigment. The film strips can also be added with a flame retardant and an anti ultraviolet absorber. The full-light-shading polyolefin greenhouse curtain has excellent light shading performance, has flame retardance, can meet the requirement of the service life, and meanwhile can prevent fires caused by electrical appliance aging to protect the property safety and personal safety.

Description

Full shading TPO greenhouse curtain

Technical field

The present invention relates to greenhouse curtain, especially full shading TPO greenhouse curtain, is gardening greenhouse suspension type, rectilinear energy-conservation heavy curtain, also can be used as the fire-retardant insulating course in other places.

Technical background

The advance in greenhouse is that the growth of crop does not rely on natural daylight entirely.When lacking the date of sunshine, as run into the period in rainy season and dark, in order to make plant growth unaffected, the method that application light compensating lamp carries out light filling is quite general, but method brings light pollution again, especially at night simultaneously.For making light all act on crop, not causing waste and light pollution, therefore being the most effective, most economical with full shading film, is a kind of by the main method accepted extensively of plantation.But full shading sunshade heavy curtain is more difficult replacing during plant growth, thus its service life generally will as long as five years more than.

Because greenhouse has cable installation, the aging of circuit causes flare, and flare can cause fire once scurry into sunshade heavy curtain, damages plant, causes wealth to lose, also bring hidden danger to personal safety.Therefore, providing fire-retardant shading curtain to be the problem being badly in need of at present addressing.

Summary of the invention

In view of above problem, the object of the present invention is to provide a kind of full shading TPO greenhouse curtain that can be fire-retardant.Concrete technical scheme is as follows:

A kind of full shading TPO greenhouse curtain, it is characterized in that, described heavy curtain forms by film bar with as the PET long filament braiding of warp and parallel, and described film bar comprises the full shading film of single or multiple lift, and the thickness of the described full shading film of each individual layer is 40 ~ 70 μm; Containing 3000 ~ 6000 object inorganic sunscreen in shading system, described inorganic sunscreen is Chinese white, black pigment, gray paint or silver color pigment.

Described Chinese white is rutile type titanium white, and content is polyolefinic 15 ~ 30%.

Described black pigment is inorganic carbon black, and content is polyolefinic 15 ~ 30%.

Described gray paint is mass ratio is the rutile type titanium white of 1:1 and the mixture of inorganic carbon black, and content is polyolefinic 15 ~ 30%.

Described silver color pigment is aluminium silver powder, and content is polyolefinic 10 ~ 25%.

Also containing flame-retardant system, UV system in described full shading film: described flame-retardant system is containing Phosphorus, phosphorus-nitrogen containing class, nitrogen alkoxyl hindered amines or halogen fire retardant.From environmental protection on, nitrogen alkoxyl hindered amines preferentially can be adopted.Described UV system is ultraviolet-resistant aid, and Benzotriazole Ultraviolet Stabilizer can be adopted also can to adopt compound hindered amine light stabilizer, specifically can select 326,327 of BASF, 111,494.

The braiding of full shading TPO greenhouse curtain in the present invention: adopt tricot machine processing, black side can be woven into as lower floor and PET long filament the full shading sunshade net that width is 2 ~ 4m in braiding process, silver color face also can be adopted as upper strata.Film is tiled successively by 4 ~ 6mm film bar, and the parallel be made up of PET long filament and warp shape structure into the net, be woven in film wherein.

The shading excellent performance of full shading TPO greenhouse curtain of the present invention, and there is anti-flammability, both meet the requirement in service life, prevented the aging fire caused of electrical equipment simultaneously, protect property safety and personal safety.

Detailed description of the invention

Below by embodiment, the present invention is specifically described.What be necessary to herein means out is; following examples are only for the invention will be further described; can not limiting the scope of the invention be interpreted as, some nonessential improvement and adjustment that professional and technical personnel's content according to the present invention in this field is made, still belong to protection scope of the present invention.

Embodiment 1

A kind of full shading TPO greenhouse curtain, wherein heavy curtain forms by film bar with as the PET long filament braiding of warp and parallel, and film bar comprises the full shading film of single or multiple lift, and the thickness of the described full shading film of each individual layer is 40 ~ 70 μm; Containing 3000 ~ 6000 object inorganic sunscreen in shading system, inorganic sunscreen is Chinese white, black pigment, gray paint or silver color pigment.

The film bar of the present embodiment has three layers, and as shown in Figure 1, be white layer 1, white layer 2, black layer 3 respectively, wherein the thickness of white layer 1 is 25 μm, containing 15 ~ 30% rutile type titanium whites; The thickness of white layer 2 is 15 μm, containing 15 ~ 30% rutile type titanium whites; The thickness of black layer 3 is 30 μm, containing 15% ~ 30% inorganic carbon black.

Also containing flame-retardant system, UV system in film bar: described flame-retardant system is containing Phosphorus, phosphorus-nitrogen containing class, nitrogen alkoxyl hindered amines or halogen fire retardant.From environmental protection on, nitrogen alkoxyl hindered amines preferentially can be adopted.Described UV system is ultraviolet-resistant aid, and Benzotriazole Ultraviolet Stabilizer can be adopted also can to adopt compound hindered amine light stabilizer, specifically can select 326,327 of BASF, 111,494.
