Abstract
The present invention relates to a kind of nano heat-insulating agricultural film, including transparent basement membrane and transparent resin bed, more than 80% cut-off rate, 58% cut-off rate of 380nm ultraviolets and more than 93% transmitance of visible ray wherein in resin bed containing nanometer heat insulation material and with 780nm -2400nm wavelength infrared rays.Heat-insulated compound agricultural film provided by the invention has the higher higher infrared ray cut-off rate of visible light transmissivity and suitable ultraviolet ray transmissivity.Present invention utilizes crops to spectrum and the requirement of the best growing condition of temperature.Rational technical indicator is found out in ultraviolet and visible ray while considers the weatherability i.e. usage time of film to basement membrane.Utilize the hot rate of release formed on membrane material in one layer of insulating course reduction greenhouse.So as to have the function that insulation.
Description
Technical field
The present invention relates to agricultural technology field, especially a kind of nano heat-insulating agricultural film.
Background technology
Polyethylene film and polyester film have been widely used as agricultural greenhouse awning film at present.But existing awning film is not due to having
There is heat insulating function so that the diurnal temperature less stable in greenhouse, be unfavorable for the growth of crop.The water spray drop used at present
Though some other gentle method can play certain heat insulating function, the diurnal temperature stability in greenhouse is improved, causes greenhouse
It is complicated, cost is high.
In addition to having suitable temperature, suppression and pest and disease damage of the appropriate ultraviolet to harmful bacteria are prevented for the growth of crops
It is all indispensable to control, and the cut-off environment excessive to ultraviolet is unfavorable for the growth of crop, be used alone ITO or ATO every
Hot powder all has excessive suppression to ultraviolet, and its transmitance is all below 20%.
