Greenhouse film capable of resisting exposure to sun, preserving heat and being ventilated

Abstract

The invention discloses greenhouse film capable of resisting exposure to the sun, preserving heat and being ventilated. The greenhouse film comprises woven mesh shape bottom film, several pieces of waved covering film which covers the bottom film and a sun resisting net; the sides of the several pieces of waved covering film are fixed to the bottom film, and the other side of each waved covering film is fixed to the adjacent waved covering film through a porous ventilated cushion; an interlayer formed between the bottom film and the covering film is filled with heat preservation particles; thetop of the greenhouse film capable of resisting exposure to the sun, preserving heat and being ventilated is connected with the sun resisting net through an upright locking seam. The provided greenhouse film capable of resisting exposure to the sun, preserving heat and being ventilated has better heat prevention performance, better ventilated performance and better water-proof performance, when the greenhouse is faced with the blazing sun, the sun resisting net can be put down to achieve the effect of preventing exposure to the sun, and the practicability of the greenhouse thin film is greatly improved.

Description

technical field [0001] The invention relates to the field of film manufacturing, in particular to a sun-proof, heat-preserving and breathable greenhouse film. Background technique [0002] The current vegetable greenhouse film is usually a single-layer design. Due to sunlight or the respiration of the plant itself, a large amount of water vapor will be generated. Because of the good airtightness of this vegetable greenhouse, water vapor cannot leak out, which will cause the inside of the greenhouse to be stuffy. , It will also condense after cooling down, and it will fall on the staff, which is very inconvenient to use. [0003] The thermal insulation performance of the single-layer greenhouse in the prior art is not good, and the temperature difference between day and night is large, resulting in a large temperature difference in the greenhouse, which cannot effectively simulate constant temperature control. When entering summer, the sun exposure will also make the tempera...

[0002] The current vegetable greenhouse film is usually a single-layer design. Due to sunlight or the respiration of the plant itself, a large amount of water vapor will be generated. Because of the good airtightness of this vegetable greenhouse, water vapor cannot leak out, which will cause the inside of the greenhouse to be stuffy. , it will also condense after cooling down, and it will fall on the staff, which is very inconvenient to use

[0003] The thermal insulation performance of the single-layer greenhouse in the prior art is not good, and the temperature difference between day and night is large, resulting in a large temperature difference in the greenhouse, which cannot effectively simulate constant temperature control

In summer, the sun exposure will also make the temperature inside the greenhouse too high, which is not suitable for the growth of plants or the work of workers.
