Description
Technical field
The present invention relates to green house energy-saving heat preserving cladding material technical field, is a kind of bubble type Windproof thermal insulation quilt.
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, if night, booth top covered without insulation material, owing to there is not solar radiation, the heat that the interior Absorbing Sets 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, morning the sun out after, the insulation covering on the canopy face is rolled, collect the temperature photosynthetic, 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 the 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 such 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, such 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 in a single day water inlet 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 technique, 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 that wind-proof performance is relatively poor by strong wind in addition.Therefore, the insulation used of existing green house covers apparatus and has the following disadvantages in actual use: wind-proof performance is relatively poor, water proofing property is poor, easily freeze, wet after heat-insulating property poor, wet after heavier being difficult for roll.
Summary of the invention
The invention provides a kind of bubble type Windproof thermal insulation quilt, overcome the deficiency of above-mentioned prior art, it can effectively solve, and the wind-proof performance that existing green house energy-saving heat preserving cladding material exists is relatively poor, water proofing property is poor, easily freeze, wet after the heat-insulating property problem that is difficult for rolling after poor, wet.
Technical scheme of the present invention realizes by following measures: a kind of bubble type Windproof thermal insulation quilt comprises body and windproof rope; Body is fixed with windproof rope along its length, body comprises the top bed of material, heat-insulation layer and the following bed of material, 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.
The below is the further optimization and/or improvements to the foregoing invention technical scheme:
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.
Above-mentioned windproof rope can comprise front windproof rope and rear windproof rope, front windproof rope and rear windproof rope lay respectively at forward edge and the rear part edge place of body, the left end of front windproof rope and rear windproof rope extend out to the left end outside of body, perhaps the right-hand member of front windproof rope and rear windproof rope extend out to the right-hand member outside of body, and perhaps the two ends, the left and right sides of front windproof rope and rear windproof rope extend out to respectively 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, perhaps can be fixed with reflective ventricumbent light reflecting membrane layer between undermost plastic bubble film pad and the following bed of material.
The bed of material can be and is distributed with reflective material on the upper surface or with the ageing-resistant fabric of reflective supine reflexed light film above above-mentioned.
The bed of material can be and is distributed with reflective material on the lower surface or with the ageing-resistant fabric of reflective ventricumbent reflexed light film below above-mentioned.
