Abstract
The invention relates to a North China season type greenhouse snow film. An outer layer, a middle layer and an inner layer are respectively subjected to film blowing through a film blowing machine and then are hotly sealed, so that the snow film is formed; the thickness ratio of the outer layer to the middle layer to the inner layer is 3:3:4; the whole thickness of the snow film is 0.01mm; the outer layer of the snow film is made of dark color PE (Poly Ethylene) grains, so that the heat energy is effectively absorbed, the heat-insulating effect is increased, the snow can melt and the damage of the accumulated snow to a greenhouse is avoided; the inner layer of the snow film is made of light-reflecting PE grains, the light in the greenhouse can be effectively reflected and the brightness in the greenhouse is increased; and the middle layer of the snow film is made of high pressure materials and linear PE materials, so that the strength of the snow film is increased. The snow film is scientifically designed and is simply manufactured; the defects of the present greenhouse film are effectively overcome; the scientific and technological level of the greenhouse is increased; and the development of the greenhouse industry is promoted.
Description
Technical field
The invention belongs to agriculture field, relate to the canopy film of booth, especially a kind of North China season type snow film.
Background technology
Along with the development of agricultural science and technology, the production of adopting booth to carry out vegetables in improper season has become an industry of agricultural.Can be incubated by the canopy film in the booth, moisturizing etc., to produce the environment that is fit to vegetable growth.For the North China, winter, temperature was lower, and travel fatigue is larger, and the canopy film upper surface of booth can fall last layer dust and affect the light transmission of canopy film, and therefore, the light in the winter booth mainly is to realize by the incandescent lamp in the booth.In addition, existing canopy film mainly adopts plastic film, and the reflective of plastic film is relatively poor, and cold is stronger thoroughly, and heat insulating ability is relatively poor.More seriously, the snowflake in winter can cover on the canopy film, perhaps freezes at ceiling, easily press the booth that collapses, and the weight capacity of existing plastic film and life-span is all relatively poor, causes booth all will change the canopy film every year and raise the cost.
By the Searches of Patent Literature, find two pieces of publication documents:
1, one class can be beneficial to particularly vegetables of crops, the novel agricultural plastic greenhouse film (CN1307070) of fruit tree and floriculture, by adding inorganic-organic mixed type fluorescer, can make plastic greenhouse film have two kinds of light functions, absorbing in the natural daylight the disadvantageous wavelength of crop growthing development is the ultraviolet light of 200-400nm wave band and the green glow of 480-570nm, converting the wavelength that crops photosynthesis needs most to is the orange red light of 590-680nm, and launching the wavelength that crop photosynthesis needs most is the blue light of 410-470nm, the orange red light of 590-680nm and the infrared light that can improve the 700-760nm of canopy temperature.Under natural light irradiation, the kinds such as crops, fruit tree and flowers of cultivating under these two kinds of plastic tunnels provide high photosynthesis ability and have improved the canopy temperature, thereby reach the purpose that promotes crop growthing development and increase fruit quality.
2, a kind of single, double layer suspending air room thermal insulation greenhouse mould and mould (CN1326668), canopy mould are by upper and lower outstanding air chamber, and upper and lower tunic and barrier film form, and the canopy film is a blow molding; Mould is that middle die body is positioned between upper die body and the lower mold body by adjusting bolt is fastening, and adjusting bolt realizes the thickness of rete for the size of regulating the die body gap.The top layer of structure of the present invention is the tension type thick film, can bear the direct destruction of external environment and the negative effect that harsh weather is brought, lower membrane and barrier film are thinner, but relative area is larger than upper layer film, thereby form a kind of outstanding air chamber structure arranged side by side that naturally dangles, when overhang opens up into certain when spending, air pressure relative equilibrium, gas pay thickness and heat-insulating property keep stable.
Through technical comparison, above-mentioned publication document and present patent application have more different.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, a kind of North China season type snow film that reflective, snow melt and good toughness, pulling force are strong, the life-span is long that has is provided.
The objective of the invention is to be achieved through the following technical solutions:
A kind of North China season type snow film, described snow film by outer, intermediate layer and nexine by inflation film manufacturing machine respectively behind the blown film heat seal form, outer, intermediate layer and nexine thickness proportion are 3:3:4, the general thickness of snow film is 0.01mm.
And, the skin of described snow film by PE black or dark particles add EVA, high binder is made.
And the intermediate layer of described snow film is made by high binder and linear PE material.
And the nexine of described snow film is made by the reflective masterbatch of PE.
Advantage of the present invention and good effect are:
1, this snow film adopts the heat seal of three layers of process to form, and has improved the toughness of canopy film, and tensile strength is high, and solid reliable, the life-span is long.
2, the outer membrane of this snow film adopts dark-coloured PE particle to make, and can effectively absorb heat energy, not only can improve heat insulation effect, simultaneously also can snow melt, and the harm of avoiding accumulated snow that booth is caused; The nexine of this snow film adopts reflective PE particle to make, and the light in can the usable reflection canopy improves the brightness in the canopy; The intermediate layer of this snow film adopts high binder and linear PE material to make, and can improve the snow film strength.
3, this snow film design science is made simply, has effectively overcome many drawbacks of existing canopy film, has improved the scientific and technological level of booth, has promoted the development of booth industry.
Description of drawings
Fig. 1 is cross section structure cutaway view of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing and by specific embodiment, and following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
A kind of North China season type snow film, its cross section structure be referring to Fig. 1, is made of outer 1, intermediate layer 2 and nexine 3, outer, intermediate layer and nexine by inflation film manufacturing machine respectively behind the blown film heat seal form, its thickness proportion is 3:3:4, the general thickness of snow film is about 0.01mm.
The skin of snow film by PE black or dark particles add EVA, high binder is made, the adding proportion of each material changes according to the difference in area.In the large area of snowfall, the ratio of corresponding increase PE black or dark particles.The intermediate layer of snow film is made by high binder and linear PE material, can effectively strengthen the canopy film strength, and the ratio of two kinds of materials is also according to the difference in area and difference; The nexine of snow film is made by the reflective masterbatch of PE, has illumination effect.
In the above-mentioned material, EVA is insulation material, but the Effective Raise heat insulation effect; But toughness and the pulling force of high binder Effective Raise snow film, the service life of improving the canopy film.
Preparation method of the present invention is:
With in three layers the material adding inflation film manufacturing machine, immediately heat seal of the trilamellar membrane that inflation film manufacturing machine blows out namely forms snow film finished product of the present invention respectively.
