Abstract
The utility model relates to a heat insulating curtain for village vegetable planting greenhouses. The utility model is composed of a heat insulating layer formed by textile fiber and a waterproof layer which is stuck and pressed on the heat insulating layer. The utility model has the advantages of light weight, good heat insulating effect, water penetration resistance, low temperature resistance and long service life.
Description
The utility model relates to a kind of rural area growing vegetables booth thermal insulation curtain.
Plastic tunnel be present rural area extensively adopt efficiently utilize the soil, satisfy the effective ways of urban vegetable market supply throughout the year.In order to make the plant in the green house of vegetables can be at low temperature or can tide over safely during winter, grow up at night, the insulation material that covers on it mostly is the self-editing woven straw of farmers' greatly, this woven straw mainly has the deficiency that Heavy Weight, heat-insulating property are poor, service life is short, roller shutter, the labour intensity of putting curtain are big, especially in rainy or the weather that snows, its moist and easy compression failure booth of accumulated snow, it is bigger to take up room during keeping, thereby is difficult to satisfy the use needs.A kind of booth paper appears again a few days ago by material, it is by multiwall kraft and pitch is bonding forms, though this paper is had lightweight characteristics, it only plays the effect of keeping out the wind, the insulation of booth also needs to cover woven straw again and realizes, so this technology is also unsatisfactory.
Goal of the invention of the present utility model is to provide a kind of in light weight, high insulating effect, have the good barrier water-based can the booth thermal insulation curtain.
Booth thermal insulation curtain provided by the utility model, its main feature are that its technology groups becomes: it is to be pressed together on the double-layer structure booth thermal insulation product that the watertight composition of heat-insulation layer one side is made by the formed heat-insulation layer of textile fabric with by low density polyethylene (LDPE) by high temperature bonding.
The booth thermal insulation curtain heat-insulating property that technique scheme provided is superior, and through experiment under equal conditions, heat holding curtain of the present utility model can be made canopy temperature improve 5-7 ℃ than woven straw or paper; Have favorable waterproof property, because its polyethylene surface is level and smooth, ponding not, the minority recess that its surface was existed causes ponding or freezes on its surface in winter, the also phenomenon that can not occur soaking into, and can remove accumulated snow at an easy rate, therefore also need not roller shutter in the snow sky; , this heat holding curtain also has the characteristics that can keep soft at low temperatures, not crisp hard, fracture, long service life, it is in light weight in addition, and every weight per square meter has only about 1KG, be 1/5th of woven straw weight, put the condition created for realizing that machinery is rolled up like this, reduced the amount of labour.
Embodiment in reference to the accompanying drawings describes heat holding curtain of the present utility model in detail below.
Accompanying drawing is the structural representation of this booth thermal insulation curtain.
As shown in the figure, this booth thermal insulation curtain is to be made by heat-insulation layer 1 and watertight composition 2 bonding pressings.For reducing cost, heat-insulation layer 1 wherein can or add some synthetic fibers again and make the cotton sheet of about 1 cm thick through opening hair, carding, benefit net, acupuncture by native fiber such as waste and old rag, waste silk fiber crops hair, under hot conditions, the low-density polyethylene material coating is bonded on the above-mentioned cotton sheet again, forms watertight composition 2.
Claims (1)
