Description
Technical Field
The utility model belongs to the technical field of insulation material, concretely relates to but use rubber and plastic wide application in the heat preservation heat-insulating quilt that the four seasons of different grade type agricultural greenhouse facility used as heat preservation base material.
Background
In general, the covering time of the greenhouse insulation blanket: carrying out anti-freezing and heat preservation at 16:00 in winter to 8:00 in the next day; and (5) performing sun protection and heat insulation in summer at 11: 00-15: 00.
At present, the Chinese is suitable for the shed quilt of the sunlight greenhouse, and the varieties mainly comprise:
1. black cotton shed quilt: the shed takes black core cotton as a heat-insulating core material, takes waterproof oxford woven fabric or nylon non-woven fabric as a surface material, and sews the black core cotton and the waterproof fabric together by a sewing machine. The shed quilt has the advantages that the heat preservation performance is general, the ultraviolet resistance of waterproof cloth on the surface layer of the shed quilt is poor, the service life is short (generally about 3 years or 4 years), snow water melted in rainy and snowy days can permeate into the black core cotton core material along the sewing line and is difficult to volatilize and dry, and therefore the heat preservation performance of the black core cotton core material after water absorption can be seriously reduced, and the service life is shortened.
2. Polyethylene foaming slice coiled material canopy quilt: the shed is made of polyethylene foam, is cut into coiled materials serving as a heat-insulating core material, is made of oxford woven fabric serving as a surface tensile protection material, and is glued with the polyethylene foam core material and the protection fabric. The polyethylene foam core material has the advantages of no water absorption and good heat preservation performance, but the core material is only 1.0-1.5 cm thick and is not thick enough due to high hardness and difficult curling, so the heat preservation performance is seriously influenced. The anti-ultraviolet capability of the protective cloth on the surface layer of the shed quilt is poor, and the service life of the whole shed quilt is short (about 5 years). Most seriously, no matter the black core cotton or the polyethylene foaming coiled material shed quilt is made of textile materials, the surface of the shed quilt can absorb water and freeze, so the shed quilt must be rolled up when snowing in winter, otherwise, the accumulated snow on the surface of the shed quilt is difficult to remove after the snow falls, and even the shed chamber collapses; after the accumulated snow melts, ice can be formed on the surface of the shed quilt, so that the shed quilt is difficult to roll up and is very easy to scratch the cloth on the surface of the shed quilt. Therefore, when the crops in the sunlight greenhouse need to be kept warm in winter, the greenhouse quilt must be rolled up but cannot be kept warm, so that the crops in the greenhouse are extremely easy to be damaged and frozen, and the yield is reduced or even the crops are completely harvested.
3. Rubber and plastic coiled material shed quilt: CN203226084U discloses a sunlight greenhouse shed, which uses a rubber-plastic coiled material as a heat-insulating core material, and adopts a thermal flow-casting process to adhere an anti-aging black polyethylene film on the rubber-plastic surface to form an integral shed. As the rubber-plastic coiled material of the core material of the shed quilt has the characteristics of no water absorption of closed pores and excellent heat preservation performance, and the black anti-aging polyethylene film on the surface of the rubber-plastic coiled material has excellent anti-aging performance, the shed quilt overcomes the defects of water absorption or no aging resistance compared with the two shed quilt types, and becomes a third shed quilt type. The rubber-plastic black polyethylene film-coated sunlight greenhouse quilt has the characteristics of low heat conductivity coefficient, good heat insulation performance, complete non-water absorption and the like, and becomes a development trend of greenhouse quilts.
However, the sunlight greenhouse is wide in geographical area, and the climate conditions such as temperature, ultraviolet intensity, wind power, snow fall, rainfall and the like in different areas are very different. The third shed cover type has serious physical defects and application area limitations, and cannot meet market demands of different geographical areas, different planting varieties, different facility types and different planting seasons. Firstly, an aluminum foil layer is sprayed on an inner protective layer to form an aluminum foil-covered polyethylene film, the aluminum material used by the aluminum foil is high in heat conduction capacity, so that the heat insulation performance of the aluminum foil-covered polyethylene is low, the aluminum foil and the polyethylene film of the aluminum foil-covered polyethylene film are hot-bonded by a high molecular material, the high molecular material is low in ageing resistance and easy to age and delaminate under sunlight irradiation, the service life of the aluminum foil-covered polyethylene film is not long, after the shed is rolled up in the daytime, a part of the inner protective layer of the aluminum foil-covered polyethylene film is exposed to the sun all the year round, the part of the aluminum foil-covered polyethylene film is easy to age, crack and even delaminate and crack, and the service life of the whole shed is greatly shortened; secondly, the design of the black polyethylene film of the outer protective layer limits the practical application range of farmers, and as the greenhouse quilt has the characteristic that the inner material and the outer material do not absorb water, many users hope to use the greenhouse shed for covering and shading the sun in summer, but the upper surface material of the greenhouse shed is the black polyethylene film, the black heat absorption is extremely strong, and the covered surface of the greenhouse can reach the high temperature of 68 ℃ in summer when the sun is strong, thereby influencing the use as a sun-shading and heat-insulating quilt; thirdly, the tearing resistance of the rubber and plastic roll material and the polyethylene film is low, and the manufactured shed is easily torn and damaged by strong wind in regions with large wind power such as northwest of Beijing and Ningxia and Xinjiang; and fourthly, the bonding surface between the outer black anti-aging polyethylene film and the inner rubber and plastic core material is easy to tear and break away, so that the shed is damaged. Because the shed is bonded with the polyethylene film and the rubber and plastic by adopting a thermal flow process, the difference of the expansion coefficients of the two materials is large, and the thermal flow process is a 'dead bonding' process, so that when the temperature of the two materials is remarkably changed in summer and winter, the surfaces of bonding layers of the two materials are torn and separated under the action of different expansion coefficients, and the shed is locally damaged; fifthly, the polyethylene adhesive tapes are used for adhering the shed quilts to form the whole shed quilt of the greenhouse, and after the polyethylene adhesive tapes are damaged by condensation, rainwater, dust and the like, the adhesive surfaces of the polyethylene adhesive tapes are easy to glue, so that the shed quilts are cracked between blocks, and the heat insulation performance is greatly reduced. For example, in the rainy regions such as Jiangsu and Jiangxi, the glue-opening phenomenon is particularly serious.
