Description
Technical Field
The utility model relates to an agricultural membrane technical field, concretely relates to scatter changes agricultural canopy membrane of light.
Background
In recent years, the planting industry of watermelons, strawberries, cucumbers, tea leaves, flowers, edible fungi, Chinese herbal medicines, gingers, hami melons, grapes, green-leaf vegetables, broccoli, fruit trees and the like is rapidly developed, and the requirement on agricultural greenhouse films is higher and higher. With the continuous progress of agricultural film production technology in China and China, various special greenhouse films are added into the raw materials of the greenhouse film, such as a greenhouse film special for watermelons, a greenhouse film special for strawberries, a greenhouse film special for cucumbers and the like. However, the types of the existing agricultural functional greenhouse films are few, and most of the agricultural greenhouse films have single functions and cannot meet the growth requirements of crops. The direct light has high ultraviolet intensity, carries more heat energy, easily burns leaves, has more shadow parts, influences photosynthesis of the leaves at the bottom and causes yield reduction. Therefore, it is necessary to develop a diffuse scattering light-conversion agricultural greenhouse film which can realize better diffuse scattering and light conversion effects, reduce direct illumination intensity, reduce the phenomenon of blade focal edges, convert harmful light into favorable light and achieve the effects of increasing yield and increasing efficiency of crops cultivated in a facility through the design of a multilayer structure.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a through multilayer structure's design, can realize better scatter and change light effect, can reduce and penetrate illumination intensity directly, reduce the burnt limit phenomenon of blade to can turn into favourable light with harmful light, reach the scatter of facility cultivation crop yield increase synergism and change light agricultural canopy membrane.
In order to achieve the above object, the utility model provides a following technical scheme: a diffuse scattering light conversion agricultural greenhouse film comprises three layers, namely a diffuse scattering layer, a light conversion layer and a base layer from top to bottom, wherein the thickness ratio of the diffuse scattering layer to the light conversion layer to the base layer is 0.5-1: 0.5-1: 1.
furthermore, the thickness of the diffuse scattering light conversion agricultural greenhouse film is 0.01-0.12 mm.
Further, the diffuse scattering layer is made of bimodal polyethylene.
Further, the light conversion layer is made of a polymer of ethylene, propylene or higher olefin added with a light conversion agent.
Further, the base layer is made of polyethylene.
The utility model has the advantages that: the utility model provides a diffuse scattering changes light agricultural canopy membrane, through multilayer structure's design, can realize better diffuse scattering and changes light effect, the material of the superiors diffuse reflection layer adopts bimodal polyethylene, reduces direct illumination intensity, reduces the burnt limit phenomenon of blade, increases the leaf surface light fertilizer area, realizes that the illumination is weak in the morning and evening the temperature also is higher in the canopy, and the illumination is strong at noon the temperature also is lower in the canopy, and this agricultural canopy membrane is used for the flower planting effect best; the light conversion layer can convert harmful light into favorable light, and convert ultraviolet light and green light in sunlight into blue light and red light which are favorable for plant growth, so that the effects of yield increase and efficiency increase of facility cultivated crops are achieved; the base layer has larger thickness in the agricultural greenhouse film and provides mechanical support for supporting and laying the greenhouse film; the diffuse scattering layer and the light conversion layer interact with each other, so that the anti-aging effect is achieved, and the service life of the greenhouse film is prolonged.
Drawings
Fig. 1 is a schematic cross-sectional view of a diffuse scattering light-converting agricultural greenhouse film provided by the present invention;
in the figure: 1-diffuse scattering layer, 2-light conversion layer and 3-base layer.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: a diffuse scattering light conversion agricultural greenhouse film comprises three layers, namely a diffuse scattering layer 1, a light conversion layer 2 and a base layer 3 from top to bottom, wherein the thickness ratio of the diffuse scattering layer 1 to the light conversion layer 2 to the base layer 3 is 0.5-1: 0.5-1: 1.
the thickness of the diffuse scattering light conversion agricultural greenhouse film is 0.01-0.12 mm.
The utility model provides a diffuse scattering changes agricultural canopy membrane of light, the concrete example of its thickness includes but not limited to 0.06, 0.07, 0.08, 0.09, 0.10, 0.12, 0.14 its each layer raw materials all can directly purchase and obtain, can obtain through the three-layer crowded altogether.
The diffuse scattering layer 1 is made of bimodal polyethylene. The bimodal polyethylene refers to a polyethylene resin with a molecular weight distribution curve showing two peaks, and compared with the common polyethylene, the bimodal polyethylene has excellent physical and mechanical strength and excellent processability, wherein a high molecular weight part is used for ensuring the physical and mechanical strength of the bimodal polyethylene, and a low molecular weight part plays a role in lubricating the resin so as to improve the processability of a product.
The light conversion layer 2 is made of ethylene, propylene or higher olefin polymer with light conversion agent. The film made of the material has high transparency, low haze and low scattering rate, can quickly increase the temperature in the greenhouse in the morning or rainy days after being used for the greenhouse film, leads crops to be mature in advance and appear on the market in advance, and can effectively convert harmful light such as ultraviolet light and the like into red light and blue light which are beneficial to the plants due to the light conversion agent in the film, thereby improving the utilization rate of sunlight and improving the light quality.
The base layer 3 is made of polyethylene. Polyethylene (PE) is a thermoplastic resin obtained by polymerizing ethylene. In industry, copolymers of ethylene with small amounts of alpha-olefins are also included. The polyethylene is odorless and nontoxic, feels like wax, has excellent low-temperature resistance (the lowest use temperature can reach-100 to-70 ℃), has good chemical stability, and can resist corrosion of most of acid and alkali (cannot resist acid with oxidation property). Has good flexibility, extensibility, transparency, cold resistance and processability, has good chemical stability, can resist acid, alkali and salt aqueous solution, and has good electrical insulation and air permeability.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
