Description

The infrared heat insulation farm-oriented quilt of bubble chamber formula

The utility model relates to a kind of insulation material, the infrared heat insulation farm-oriented quilt of specifically a kind of bubble chamber formula of using on agricultural green house of vegetables.

At present, green house of vegetables is the large tracts of land use of vast rural area in the north, green house of vegetables needs sunlight to see through plastic film the daytime or glass impels plant growing, then need booth to be built insulation to evening and prevent that crop is damaged by frost with thermal insulation quilt, in the prior art, for the material of vegetable booth thermal insulation have straw screen or mat, careless tongue, paper by etc., the greenhouse by solar heat of preceding nearly 3,000,000 mu medium and small green house of vegetables and 2,500,000 mu uses straw screen or mat and straw mat to carry out outer insulation and covers, and annually needs to consume more than 200,000,000 and make the paper quilt.The application region of woven straw is mainly in the middle and lower reach of Yangtze River and the south of the lower reaches of the Yangtze River, and the application of straw mat and paper quilt is mainly in the Yellow River and Huai He River Haiti district, North China, northeast and the Northwest.

There is bibliographical information to have the people to make cotton felt with nonwoven, coat watertight composition again as the plastic tunnel thermal insulation quilt, also there is the nonwoven of use to make cotton felt, coat watertight composition again as the plastic tunnel thermal insulation quilt, also have and use the chemical fibre offcuts to make insulation quilt and with PVC foam coiled material overlay film and use the plastic foamed chemical fabric that is laminated with of PE as thermal insulation quilt, the low heat insulating ability of the not busy porosity that the above-mentioned in use existing deficiency of thermal insulation quilt that supports with organic material is an abscess can be low etc.; The support structure thermal insulation quilt of also useful " cotton-felt-cotton-felt-plastic woven cloth is pressed layer ", its weak point is still the cost height, is not suitable for China's actual conditions, thereby is difficult for large scale application.

To be that the brown paper multilayer is folded make rib hole coiled material with general paper, but its moisture resistance is not good, and thermal conductivity factor is too big, and heat insulation effect is equivalent to the straw mat curtain and still exists on the high side and volume is put folding inconvenience.Therefore, at present plastic tunnel covers thing and can only take product as the leading factor with the straw mat curtain, but straw mat, straw screen or mat are made the deficiency that insulation material in use deposited and be:

1, corrosion resistant is not mashed, and is perishable after the sleet water logging, and heavy support desired strength height (cost rising virtually) to booth, maximum 3 years of service life.

2, in the coiling process of every day, straw mat many dusts that can fall down stick to above the booth easily, even cleaning, water also is difficult for falling down, especially the more difficult cleaning of PVC film greatly reduces the light penetration of horticultural covering film, influences illumination and temperature causes crop failure;

3, increased user's labour intensity to the covering of green house of vegetables with open operation every day.

4, heat insulation effect is poor, and a little less than main because straw mat stops that the outwards auxilliary function of penetrating of IR, and the coefficient of straw mat is also bigger, and about about 0.2-0.3, the straw mat curtain heat-insulating property after watered by rainwater, snow-broth is poorer.

5, easily puncture, scratch face.Along with agriculture scale compartmentalization is produced, the construction of plastic tunnel is used and more and more is tending towards extensive development, and the insulation straw mat far can not satisfy the demand of modern efficient main body agricultural.The purpose of this utility model provides a kind of airtight, waterproof; Can stop that infrared rays is outwards auxilliary penetrates high insulating effect; Dustproof easily curling, easy lay; The infrared heat insulation farm-oriented quilt of the bubble chamber formula of long service life.

The purpose of this utility model realizes in the following manner, the support membrane of being made by plastic film is set between two layers of plastic thin films, between between the two layers of plastic thin films, be separated out separate bubble chamber by support membrane, have heat insulating ability preferably because so the bubble chamber that is provided with secluding air between the double-layer films uses as the thermal insulation quilt of green house of vegetables, and have in light weight, easy lay, do not go mouldy, advantage such as long service life.

Accompanying drawing is the structural representation of the infrared heat insulation farm-oriented quilt of bubble chamber formula.

Explain below with reference to Figure of description the infrared heat insulation farm-oriented quilt of bubble chamber formula of the present utility model being done.

The infrared heat insulation farm-oriented quilt of bubble chamber formula of the present utility model, its structure is to be made of surface heat preservation film 2 and intermediate supports film 3, intermediate supports film 3 is fixed between the surface heat preservation film 2, is being provided with the heat insulation bubble chamber 1 that is separated out between between the two layers of surface insulation film 2 by intermediate supports film 3 between intermediate supports film 3 and the surface heat preservation film 2.

Embodiment:

Infrared its processing and fabricating of heat insulation farm-oriented quilt of bubble chamber formula of the present utility model is very simple and convenient, and processing shown in the by specification accompanying drawing gets final product, combining and can finish by general-purpose plastics film adhesion technique between support membrane and the skin covering of the surface.The moulding of support membrane can be passed through plastic uptake or gas filling technology moulding.

Can be added with inorganic in raw material or organic filler in the manufacturing process of skin covering of the surface, be used to intercept ultrared radiation, strengthen heat-insulating property, its function possesses: airtight, waterproof; Stop infrared rays outwards auxilliary penetrate and the heat conduction little, high insulating effect; Dustproof easily batch, easy lay; Service life 3-5; Every mu of booth of surviving the winter of cost increases disposable insulation material and takes 400-500 unit, every mu of annual insulation material investment 100-160 unit that increases is near purchasing straw mat insulation investment, but from increasing heat insulation effect, vegetables are gathered in the crops in advance sell at high price and make output to increase by 10% left and right sides economic benefit, select for use farm-oriented quilt of the present utility model can make mu increase about 1000 yuan of economic benefits, thereby, have good economic benefits and popularizing value.
