Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation materials, and particularly relates to a multi-layer composite greenhouse thermal insulation quilt. Background Art

[0002] During the production process of the greenhouse, greenhouse thermal insulation quilts are usually used to insulate and protect the greenhouse; however, due to the wide geographical distribution of solar greenhouses, the climatic conditions such as temperature, ultraviolet intensity, wind force, snowfall, rainfall, etc. in different regions vary greatly. Traditional chemical composite layer greenhouse thermal insulation quilts are prone to aging and delamination under sunlight, resulting in short service lives of materials such as aluminized polyethylene films;

[0003] Therefore, to solve this problem, we propose a multi-layer composite greenhouse thermal insulation quilt that can effectively ensure the connection strength. Content of the Utility Model

[0004] Aiming at the defects in the prior art, the utility model provides a multi-layer composite greenhouse thermal insulation quilt to improve the connection strength of the greenhouse thermal insulation quilt.

[0005] A multi-layer composite greenhouse thermal insulation quilt provided by the utility model includes: a rubber and plastic layer, a reflective layer, and an outer protective layer; wherein two layers of the rubber and plastic layer are provided and are respectively arranged on both sides of the reflective layer and fixedly connected to the reflective layer; two outer protective layers are provided and are respectively connected to the rubber and plastic layer and arranged on the outer surface of the rubber and plastic layer; the outer protective layer is fixedly connected to the rubber and plastic layer; the rubber and plastic layer is provided with fine holes; a plurality of the fine holes are provided and are arranged on the surface of the rubber and plastic layer, and the fine holes extend towards the reflective layer; the outer protective layer is a multi-layer co-extruded anti-aging polyethylene film, and the black or white side faces outwards; wherein the outer protective layer extends into the fine holes through a hot melt process; the reflective layer is used for heat insulation.

[0006] Further, the multi-layer anti-aging polyethylene films of the outer protective layer are in sequence a first anti-aging transparent heat-sealing film layer, an anti-ultraviolet black film light-blocking layer, a first anti-aging milky white film reflective layer, a second anti-aging milky white film reflective layer, and a second anti-aging transparent heat-sealing film layer. In practical application, the anti-aging polyethylene film used for the outer protective layer is used as the surface material of the rubber and plastic greenhouse quilt, so that the rubber and plastic greenhouse quilt has the properties of anti-aging, anti-ultraviolet, light reflection, and easy heat-sealing bonding during installation.

[0007] Further, the fine holes in the rubber and plastic layer are made by a vacuum adsorption process. In practical application, through this vacuum adsorption process, the porous design of the rubber and plastic layer is realized, and at the same time, the fine holes are more evenly distributed. Moreover, the vacuum adsorption process is an existing technology and is realized by a vacuum machine. In this way, a plurality of fine holes can be quickly formed in the rubber and plastic.

[0008] Furthermore, the multi-layer anti-aging polyethylene film of the outer protective layer is bonded by hot melt adhesive. In actual application, this design effectively ensures the connection strength of the outer protective layer.

[0009] Furthermore, the reflective layer is made of aluminum foil. In actual use, this design effectively ensures thermal insulation, and through the characteristics of the aluminum foil material, it realizes the core protection of the greenhouse.

[0010] It can be seen from the above technical solution that the beneficial effects of the multi-layer composite greenhouse insulation blanket provided by the utility model are:

[0011] (1) In actual use, the five-layer protection design adopted by this design effectively improves the thermal insulation protection of the greenhouse;

[0012] (2) At the same time, the setting with the reflective layer as the core greatly ensures the strength of the greenhouse insulation blanket and can achieve reflective insulation;

[0013] (3) The rubber-plastic layer is provided with a plurality of fine holes, which allow the material of the outer protective layer to extend into the fine holes. In this way, the connection between the outer protective layer and the rubber-plastic layer can be greatly enhanced, so that the outer protective layer is not easy to fall off in an external environment with sun, rain, cold and heat.

[0014] (4) The hot melt process involves bonding by heating hot melt adhesive. BRIEF DESCRIPTION OF THE DRAWINGS
