Abstract
The utility model relates to a greenhouse heat-preserving quilt, which comprises a polyethylene terephthalate (PET) metalized film, a netted pull layer and a main heat-preserving layer, wherein the netted pull layer is arranged on the lower surface of the PET metallized film; and the main heat-preserving layer is arranged on the lower surface of the netted pull layer. The greenhouse heat-preserving quilt has obvious heat-preserving performance, is light in integral weight and convenient to roll and spread and has high stretching resistance, so the damage in the stretching process is avoided effectively, and the service life of the heat-preserving quilt is prolonged; and the greenhouse heat-preserving quilt has high waterproof performance, and the phenomena of water absorption and water permeability are avoided.
Description
Technical field
The utility model belongs to the shade of usefulness such as greenhouse, booth or the technical field of baffle plate or analog, and is special, relates to a kind of greenhouse heat-insulating quilt.
Background technology
In recent years, the green house crop cultivating technology is extensively promoted, and on the booth plastic foil, lays the insulation cover layer and can effectively reduce scattering and disappearing of greenhouse by solar heat heat.Over nearly 20 years, energy-saving heliogreenhouse is because its remarkable economic efficiency and social benefit are powerful in China's growth momentum.In the prior art, the insulation cover layer of laying on the booth plastic foil has been selected for use: straw mat, cattail mat and Nomex cotton-wadded quilt etc.Straw mat, cattail mat thermal insulation quilt are to utilize the straw or the stem or leaf of cattail to work out, and the Nomex cotton-wadded quilt uses waste and old short fiber to make through needling process, make to be layered on the booth surface behind the length dimension that is fit to booth and to be incubated.The weak point of prior art is: the surface emissivity emissivity is higher, and more to the space radiation dispersed heat, heat-insulating property is undesirable; By the thermal insulation quilt that ventilating structures such as cotton fiber or straw are processed, cold air penetrates thermal insulation quilt easily when blowing in the open air, makes its forfeiture heat insulation effect; Very easily soaked, can be increased several times weight, make heat insulation effect significantly descend simultaneously by straw screen or mat or cotton-wadded quilt after soaking by rain, snow; Rot easily, service life is short, and the service life of some thermal insulation quilt was less than 1 year; Quality is heavy, and volume is put and launched to use and all need spend big manpower; Release a kind of novel greenhouse heat-insulating quilt is the problem that vast farmers extremely is concerned about and is expected to solve to substitute traditional cattail mat and straw mat always.
The utility model content
The utility model provides a kind of greenhouse heat-insulating quilt, has solved the shortcoming that the straw screen or mat heat-insulating property is undesirable in the prior art, quality heavy, water proofing property is poor, service life is short.
Technical scheme is following:
A kind of greenhouse heat-insulating quilt is characterized in that including: PET aluminizer, netted pulling force layer and main heat-insulation layer; Said netted pulling force layer is arranged on the lower surface of said PET aluminizer, and said main heat-insulation layer is arranged on the lower surface of said netted pulling force layer.
Further, said main heat-insulation layer comprises: the first expanded material heat-insulation layer, first felt layers, the second expanded material heat-insulation layer and second felt layers; Said first felt layers is arranged on the lower surface of the said first expanded material heat-insulation layer, and the said second expanded material heat-insulation layer is arranged on the lower surface of said first felt layers, and said second felt layers is arranged on the lower surface of the said second expanded material heat-insulation layer.
Technique effect is following:
1, the greenhouse heat-insulating quilt heat-insulating property of the utility model is obvious.
2, the greenhouse heat-insulating quilt of the utility model so alleviated the overall weight of greenhouse heat-insulating quilt, is convenient on the greenhouse top cover, roll volume and is launched lay, or roll volume and remove receipts owing to adopt expanded material as heat-insulation layer.
3, the greenhouse heat-insulating quilt of the utility model has been laid netted pulling force layer in the expanded material bottom, fail in tension when preventing the thermal insulation quilt expansion, and surface and core are ageing-resistant material, long service life, the service life of having improved thermal insulation quilt.
4, the top layer of the temperature quilt of the utility model has adopted aluminium foil, and the centre is an expanded material, so do not have suction, permeable phenomenon takes place; Make thermal insulation quilt surface waterproof fully; The back weight of raining does not increase, and prevents that thermal insulation quilt from becoming wet and making moist, and prevents that the thermal insulation quilt thermal conductivity factor from becoming big.
5, the greenhouse heat-insulating quilt manufacture craft of the utility model is easy, cheap, is fit to large-scale promotion.
6, the greenhouse heat-insulating quilt surface emissivity emissivity of the utility model is very low, and is few to the space radiation dispersed heat, can effectively reduce the heat loss through radiation coefficient of greenhouse insulation quilt, strengthens heat insulation effect.
7, the surface of the greenhouse heat-insulating quilt of the utility model is airtight fully, does not have the inner air and outer air exchange, has reduced the heat radiation of convection current.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Be explained in detail below in conjunction with accompanying drawing and preferred embodiment technical scheme the utility model.
As shown in Figure 1, be the structural representation of the utility model.The utility model comprises: PET (PETG) aluminizer 1, netted pulling force layer 2 and main heat-insulation layer; Netted pulling force layer 2 is arranged on the lower surface of PET aluminizer 1, and main heat-insulation layer is arranged on the lower surface of netted pulling force layer 2.The PET aluminizer is used for reflection ray and waterproof action; Netted pulling force layer 2 is used to improve the stretching resistance of greenhouse heat-insulating quilt.Main heat-insulation layer comprises: the first expanded material heat-insulation layer 3, first felt layers 4, the second expanded material heat-insulation layer 5 and second felt layers 6.First felt layers 4 is arranged on the lower surface of the first expanded material heat-insulation layer 3, and the second expanded material heat-insulation layer 5 is arranged on the lower surface of first felt layers 4, and second felt layers 6 is arranged on the lower surface of the second expanded material heat-insulation layer 5.In this preferred embodiment: the first expanded material heat-insulation layer 3 and the second expanded material heat-insulation layer 5 select for use EPE (expandability polyethylene) pearl cotton to process; First felt layers 4 and second felt layers 6 are selected Nomex for use.
Use regional climate according to greenhouse heat-insulating quilt is different, and the heat insulation effect of the thermal insulation quilt that needs is also different, and the expanded material heat-insulation layer in the main heat-insulation layer of the utility model and the quantity of felt layers can increase or reduce accordingly.
