Description

Technical Field

[0001] The utility model belongs to the technical field of greenhouses, and in particular relates to a heat-insulating blanket for a vegetable greenhouse. Background Art

[0002] A greenhouse is a building that uses daylighting covering materials as all or part of the enclosure structure materials and can be used to grow plants in winter or other seasons that are not suitable for outdoor plant growth. Heating energy consumption is the main obstacle to greenhouse operation in winter. Improving the thermal insulation performance of the greenhouse and reducing energy consumption are the most direct means to improve the production efficiency of the greenhouse. The thermal insulation ratio of the greenhouse is a basic indicator to measure the thermal insulation performance of the greenhouse.

[0003] Greenhouses often use thermal insulation blankets to improve the thermal insulation performance of the greenhouse, so as to prevent the temperature of the greenhouse from dissipating. At present, the most common thermal insulation blanket is needle felt. Needle felt is made of recycled materials such as old broken wires and rags, which are processed and re-pressed. It has low cost and good thermal insulation performance. However, after one year of use, the waterproof performance drops sharply. The material absorbs water, the thermal insulation performance decreases, and it cannot be dried. As a result, it cannot be used, resulting in a waste of investment. Therefore, it is necessary to improve the thermal insulation blanket of greenhouses to solve the above problems. Utility Model Content

[0007] Optionally, the thickness of the glass wool layer is 5-15 mm, the thickness of the needle felt layer is 15-30 mm, the thickness of the polyethylene foam layer is 10-15 mm, and the thickness of the polyurethane foam layer is 20-30 mm.

[0008] Optionally, the waterproof membrane layer is a PE waterproof film or a polyurethane waterproof film, and the thickness of the waterproof membrane layer is 0.2~1.0mm.

[0009] Optionally, the protective layer is a waterproof and antifouling nano coating, for example, it can be formed by the waterproof and antifouling nano coating agent TX12.

[0010] Optionally, both the first sunshade net layer and the second sunshade net layer are flat wire sunshade nets.

[0011] Optionally, the first sunshade net layer and the second sunshade net layer are respectively more than two layers.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] Based on the above technical scheme, the utility model provides a thermal insulation blanket for vegetable greenhouses to improve the performance of the thermal insulation blanket. Specifically: the utility model achieves multiple thermal insulation effects through the cooperation of a glass wool layer, a needle felt layer, a polyethylene foam cotton layer and a polyurethane foam cotton layer.
