Description
The present invention is application number 201510787465.0, November 17 2015 applying date, a kind of denomination of invention " astigmatism drop
The divisional application of the preparation method of warm radiation protection net ".
Technical field
The present invention relates to a kind of preparation method of astigmatism cooling heat radiation prevention net, astigmatism cooling heat radiation prevention net is applicable in
Cool down in agricultural productions shadings such as summer vegetable cultivation, flower planting, the nursery of woods fruit, livestock-raisings, belongs to agricultural technology field.
Background technique
Sunshade net is also known as shading net, is a kind of novel dedicated guarantor of agriculture, forestry, animal husbandry, fisheries that nearly 10 Yu Nianlai in China is promoted
Protect covering material.Play the role of after summer covering it is certain it is light-blocking, keep off the rain, moisturizing, cooling.There are also certain after winter-spring season covering
Thermal insulation wetting effect.Currently, it is primary raw material that sunshading net for agriculture use, which is polyolefin, it is woven by wire drawing, is added when manufacture is
Enter different dyes, different colours sunshade net can be produced, changes weft density, so that it may produce the sunshade net of different shading rates.It hides
Screened postive is mainly used in summer, the irradiation of anti-burning sun, the harm of high temperature, it has also become vegetables, flowers, edible mushroom, nursery stock, medicinal material etc.
The technical measures mainly promoted that the protectiveness cultivation of crop and aquatic products, poultry farming high temperature-proof are protected.
Currently, the sunshade net of market sale, based on black, there are also the light sunshade nets in part.Black sunshade net mainly passes through
It absorbs sunlight and realizes shading, light sunshade net is absorbed by selective reflecting realizes shading.Black sunshade net shading rate is high, have compared with
Good cooling effect.But it is found in practical agricultural production, since black sunshade network technology and structural factor restrict, shading, drop
Temperature effect can't meet modern agricultural production demand simultaneously.For example, spinach is the cold-resistant plant that To Be Protected from Heat, summer is planted to environment
It is required that it is harsh, cooling is realized with traditional sunshade net, needs very high shading rate to be just able to satisfy cooling needs, but sunshade net hides
Light is too many, will affect the normal photosynthesis of spinach, influences plant nutrition Composition accumulation.
In short, existing sunshade network technology has the following deficiencies: under (1) sunshine, heat transfer is fast, and sunshade net own temperature is very high；
(2) it is more with air or periphery object to exchange heat for common sunshade net；Easily promote net ambient air temperature；(3) black sunshade netlist
The far infrared radiation amount that face generates is high；(4) it has a single function, shading, heat-insulated, cooling cannot combine.
Therefore, there is not ideal heat radiation prevention net in agricultural production also.In transformation mode of agriculture, agricultural warp is improved
Under benefit of helping and the background of energy-saving and emission-reduction, it is badly in need of a kind of astigmatism cooling heat radiation prevention net.
Summary of the invention
The problem to be solved in the present invention is against the above deficiency, to provide a kind of preparation side of astigmatism cooling heat radiation prevention net
