Description
Technical field
The utility model relates to green house energy-saving heat preserving cladding material technical field, is the windproof thermal insulation quilt of a kind of bubble type.
Background technology
In recent years, the green house development of China rapidly, green house is to lean on the sunlight on daytime to gather heat through the canopy film in the season of cold, thereby keep crop in the canopy or animal normal growth, night, booth top was if no insulation material covers, owing to there is not solar radiation, the heat that the interior absorption collection of canopy on daytime is deposited can lose very soon, crop can't normal growth in the canopy, even can freeze to death, particularly in the north of cold, must on the canopy face of green house, carry out heat preservation energy-saving by covering insulation material, certain time in season Rigen according to weather condition, after morning, the sun came out, the insulation covering on the canopy face is rolled, it is photosynthetic to collect temperature, when at dusk the sun sets soon, the insulation covering is put down be incubated again.
The insulation material that covers on the canopy face of existing green house comprises the thermal insulation quilt that paper that brown paper does is made by materials such as, the woven straws made of straw, straw, wheat straw, organic fiber, chemical fibre, plastic foamed, wherein insulation materials such as paper quilt, woven straw, straw, wheat straw easily wet, too heavy, poor, life-span of insulation lack, progressively eliminated; Organic fibrous material, very easily rotten after wetting as cotton, cotton felt, leftover of bolt of cloth cotton, Nomex, spray-bonded nonwaven fabric etc., in case water inlet is difficult to dry, even if airing is too heavy because of himself, be difficult for rolling; Chemical fibre material, as polyacrylonitrile fibre, dacron cotton and space wadding etc., its advantage is that thermal conductivity factor is little, good heat preservation performance, be convenient to batch production and produce line production, but easily suction, and too heavy after the suction, be not easy to volume and put operation, simultaneously, in water inlet in a single day in the winter of cold, wet place can be formed ice cube and can't be rolled up and put use, and thermal insulation quilt in the open air open-air wind scrape Exposure to Sunlight and artificial or machinery volume and put the destruction part is arranged in the operation unavoidably, and this class thermal insulation quilt generally is made into quilting technology, its quilting pinprick is its often main thoroughfare of water inlet, even use the waterproof fabrics protection can not accomplish effective waterproof; The heat-insulating property of polyethylene foam sheet and high density microvesicle sheet is general, and is good from waterproof, but there is the too hard shortcoming that volume is put, price is higher that is difficult in it, and increased the thermal insulation quilt volume and put load, difficulty and the cost of operation; The thermal insulation quilt made of above-mentioned material also exists easily and is swept the problem of windproof poor-performing by strong wind in addition.Therefore, the insulation used of existing green house covers apparatus and has the following disadvantages in actual use: windproof poor-performing, water proofing property be poor, easily freeze, wet back heat-insulating property poor, wet after heavier being difficult for roll.
Summary of the invention
The utility model provides a kind of bubble type windproof thermal insulation quilt, overcome the deficiency of above-mentioned prior art, its can effectively solve windproof poor-performing, water proofing property that existing green house energy-saving heat preserving cladding material exists poor, easily freeze, problem that wet back heat-insulating property is difficult for rolling after poor, wet.
The technical solution of the utility model realizes by following measure: the windproof thermal insulation quilt of a kind of bubble type comprises by body and windproof rope; By body windproof rope is arranged fixedly along its length, comprised the top bed of material, heat-insulation layer and the following bed of material by body, the top bed of material, heat-insulation layer and the following bed of material from top to bottom are fixed together successively, heat-insulation layer comprises the plastic bubble film pad that is no less than one deck, is distributed with separate on the plastic bubble film pad and seals the bubble chamber of air up for safekeeping.
Be the further optimization and/or improvements to above-mentioned utility model technical scheme below:
Above-mentioned windproof rope can be fixed in the above on the upper surface of the bed of material, perhaps windproof rope can be fixed on the lower surface of the following bed of material, perhaps windproof rope can be fixed in the above between the bed of material and the heat-insulation layer, perhaps windproof rope can be fixed between heat-insulation layer and the following bed of material, and perhaps windproof rope can be fixed on heat-insulation layer inside.
Above-mentioned windproof rope can be the ageing-resistant windproof rope that the cross section is flat.
The windproof rope of windproof rope and back before above-mentioned windproof rope can comprise, the windproof rope of preceding windproof rope and back lays respectively at by the front edges of body and rear part edge place, the left end of the windproof rope of preceding windproof rope and back extend out to by the left end outside of body, the right-hand member of the windproof rope of windproof rope and back extend out to by the right-hand member outside of body perhaps, and perhaps the two ends, the left and right sides of the windproof rope of preceding windproof rope and back extend out to respectively by the outside, two ends, the left and right sides of body.
Can be distributed with reflective material on the lower surface of above-mentioned undermost plastic bubble film pad, reflective ventricumbent light reflecting membrane layer perhaps can fixedly be arranged between undermost plastic bubble film pad and the following bed of material.
The bed of material can be the ageing-resistant fabric that is distributed with reflective material on the upper surface or has reflective supine reflexed light film above above-mentioned.
The bed of material can be the ageing-resistant fabric that is distributed with reflective material on the lower surface or has reflective ventricumbent reflexed light film below above-mentioned.
Above-mentioned plastic bubble film pad can be vinyon plastic bubble film pad or igelite plastic bubble film pad.
The utility model reasonable and compact in structure, easy to use, it is by using the light soft plastic bubble film pad again of material as heat-insulation layer, fixedly there is being the end to extend out to by the windproof rope of external body by the both sides of the edge, front and back of body, can bind by the end of body the utility model is fixed on the top, greenhouse reliably, not only good, the wind and water preventing excellent performance of heat-insulating property, not-easy-to-freeze, non-leakage water, and be convenient to volume and put, have the characteristics of low, easy durable, the economical and efficient of integrated cost.
