Abstract

The invention provides a multilayer film for an agricultural greenhouse. The multilayer film is characterized by comprising a substrate film, wherein an antifogging coating film layer is arranged on the inner side surface of the substrate film, the substrate film has an inner layer, a middle layer and an outer layer, the middle layer of the substrate film is a meshed reinforcing layer, meshes of the meshed reinforcing layer are hexagonal, the area of each mesh is greater than or equal to 5 square centimeters and smaller than or equal to 10 square centimeters, the inner layer of the substrate film is a PET-polyester plastic film, and the outer layer of the substrate film is a nylon-plastic film and contains a fluoride series surfactant ingredient. Due to the structure, the multilayer film for the agricultural greenhouse has the advantages that the tensile strength can be effectively improved, the internal surface is not prone to water droplet generation, and the lowering of light transmittance of the external surface caused by water scales resulting from long-term rainwater and raining is difficult.

Description

A kind of agricultural greenhouse multilayer film
Technical field
The present invention relates to a kind of multilayer film, particularly a kind of agricultural greenhouse multilayer film.
Background technology
Plastic sheeting is widely used in hot house field in rural area plant, utilize hot house carry out vegetable, The disparities between supply and demand alleviating vegetable dull season are served special important function, have significant society by the facility cultivation of flowers etc. Benefit and the huge economic benefit of reality.Existing hot house thin film has the disadvantage in that 1, is reducing film thickness Time can promote its light transmission, but tensile strength decreases；2, the steam in booth easily condenses at thin film inner surface, End form becomes droplet, and droplet can affect the light transmission of thin film, it addition, droplet directly falls in rice shoot after reaching certain volume On, it is likely to result in seedling rot；3, thin film is positioned on the outer surface outside booth when rainy day, and rainwater easily produces heap above Long-pending, thin film build-up of pressure is damaged, of long duration also can produce incrustation scale, affect light transmission.
Summary of the invention
In view of the deficiency of background technology, the one that the present invention provides can effectively promote and draw high intensity, and inner surface is difficult to Produce water droplet, and outer surface is difficult to the agricultural greenhouse multilamellar of the incrustation scale reduction transmittance brought because long-term rainwater rains Film.
For solving the problems referred to above, present invention provide the technical scheme that
A kind of agricultural greenhouse multilayer film, it is characterised in that: include that base material film, the inner surface of described base material film are provided with anti-fog properties Film layer, described base material film has internal layer, intermediate layer and outer layer, and described base material film intermediate layer is meshed strengthening layer, described netted The mesh of enhancement Layer is hexagonal, and the area of described mesh is more than or equal to 5 square centimeters, more than or equal to 10 square centimeters, described The internal layer of base material film be PET polyester plastics thin film, outer layer be containing fluorine system in nylon plastic(s) thin film, and the outer layer of described base material film Surfactant component.
As preferably, the thickness of described PET polyester plastics thin film and nylon plastic(s) thin film is 0.2 millimeter to 0.3 millimeter.
As preferably, the thickness of described meshed strengthening layer is 0.5 millimeter.
As preferably, the thickness of described anti-fog properties film layer is 5 microns to 10 microns.
Use after this programme, thicker base material film meshed strengthening layer improve base material film draw high intensity while, again Can guarantee that the light transmission of base material film, provide sufficient illumination condition for the plant in booth；Base material film inner surface anti-fog properties Film layer make steam be difficult to inside base material film condense, thus it is ensured that make while light transmission rice shoot be difficult to because of The globule drips and seedling rot；Base material film outer layer contains fluorine system surfactant component, and this composition can make water stain being difficult to be attached to On nylon plastic(s) thin film so that the outer layer of base material film is the cleanest and the tidiest.
Accompanying drawing explanation
The present invention provides drawings described below:
The structural representation that Fig. 1 provides for the present invention；
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
As it can be seen, a kind of agricultural greenhouse multilayer film that the present invention provides, including base material film, the inner side of described base material film Surface is provided with anti-fog properties film layer 1, and described base material film has internal layer, intermediate layer and outer layer, and described base material film intermediate layer is netted Enhancement Layer 2, the mesh of described meshed strengthening layer 2 is hexagonal, and the area of described mesh is more than or equal to 5 square centimeters, is more than In 10 square centimeters, the internal layer of described base material film be PET polyester plastics thin film 3, outer layer be nylon plastic(s) thin film 4, and described base Containing fluorine system surfactant component in the outer layer of material film.Described PET polyester plastics thin film 3 and the thickness of nylon plastic(s) thin film 4 It it is 0.2 millimeter to 0.3 millimeter.The thickness of described meshed strengthening layer 2 is 0.5 millimeter.The thickness of described anti-fog properties film layer 1 is 5 Micron is to 10 microns.
