Description
Technical Field
The invention relates to the field of film manufacturing, in particular to a heat-insulating breathable greenhouse film.
Background
The current vegetable greenhouse film is usually of a single-layer design, a large amount of water vapor can be generated due to sunlight irradiation or the breathing effect of plants, and the vegetable greenhouse film is good in tightness, cannot be penetrated out, can cause stuffiness in the greenhouse, can be condensed after being cooled, falls on the body of a worker, and is very inconvenient to use.
The single-layer greenhouse in the prior art is poor in heat preservation performance, large in day and night temperature difference, large in temperature difference in the greenhouse, and incapable of effectively simulating constant temperature control.
Therefore, there is a need for a vegetable greenhouse film that is heat-insulating and breathable.
Disclosure of Invention
In order to overcome the problems, the invention provides the heat-insulating breathable greenhouse film with good external waterproof property, good heat-insulating property and good air permeability.
The technical scheme of the invention is to provide a heat-insulating breathable greenhouse film, which comprises a woven reticular base film and a plurality of wavy films covered on the base film, wherein one side of each wavy film is fixed on the base film, and the other side of each wavy film is fixed on the wavy film adjacent to the wavy film through a porous breathable pad; and heat-insulating particles are filled in an interlayer formed between the bottom film and the covering film.
In a preferred embodiment, the woven mesh base film is woven by means of 3 or 4 or 6 needles. The woven mesh has certain light transmission and air permeability, the higher the number of selected needles is, the denser the woven mesh is, the smaller the pores are, and the lower the light transmission rate is. The above-mentioned mesh grid can be woven according to the demand to different illumination, selects suitable needle number, and the preferred needle number is 4 needles.
In a preferred embodiment, the insulation particles are transparent PET polyester particles or transparent PE particles. The transparent particles can ensure certain light transmittance. The particles have a large amount of air between them, and the air is a bad conductor of heat, so that the transparent particles arranged between the woven mesh-shaped base film and the covering film can have good heat preservation effect. Preferred transparent particles are selected from transparent PE particles.
In a preferred embodiment, adjacent two undulating membranes form ventilation openings through the porous ventilation pad, the direction of the ventilation openings being toward the ground. The porous air-permeable mat may be selected from porous sponges or foamed plastics, preferably porous sponges. In general, vegetable plants in the greenhouse adopt a scientific water supply mode, and precipitation in the atmosphere breaks the balance, and when adopting the structure, even if rainfall or snowfall occurs, the rain and the snow can fall from the wavy coating film outside, and meanwhile, the ventilation of the inside and the outside of the greenhouse is not hindered.
In a preferred embodiment, the tops of the heat-insulating breathable greenhouse films are connected by upright lock seams. In the case of covering the whole greenhouse, two independent and symmetrically arranged greenhouse films are needed to ensure that the directions of the ventilation openings are all towards the ground. At this time, the joint of the two greenhouse films needs to be vertically sewn, so that the fastening connection of the two greenhouse films is ensured, and water leakage at the joint is avoided.
In a preferred embodiment, the thickness of the heat-insulating and breathable greenhouse film is 0.3-1cm, and excessive thickness can cause the whole film layer to be too heavy, so that the safety performance is affected. Correspondingly, the average particle diameter of the filled heat-insulating particles is 0.1-0.5cm.
In a preferred embodiment, the wavy film has a width of 5-10cm, which is a relatively moderate width, and too much width results in the accumulation of thermal insulation particles in the middle and lower layers of the interlayer formed between the base film and the film due to gravity caused by too much thermal insulation particles contained therein, and too little width results in insufficient thermal insulation effect.
The beneficial effects of the invention are as follows:
1. the heat-insulating breathable greenhouse film has the advantages that through the unique design, the greenhouse film can resist external rain and snow, meanwhile, the heat-insulating effect on the interior of the greenhouse can be achieved, and meanwhile, water vapor and the like generated in the interior of the greenhouse can be exchanged with the atmosphere, so that the breathable effect is achieved.
2. The heat-insulating breathable greenhouse film can adjust the needle number of the woven mesh-shaped bottom film according to actual requirements, so that the light transmittance of the greenhouse film can be adjusted according to local conditions.
3. The heat-insulation breathable greenhouse film is convenient to use and can be directly covered on a greenhouse framework.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
1-2, the greenhouse film 1 comprises a woven net-shaped base film 11 and a plurality of wavy covering films 12 covered on the base film 11, one side of the wavy covering film 12 is fixed on the base film 11, and the other side of the wavy covering film 12 is fixed on the wavy covering film 12 adjacent to the wavy covering film through a porous ventilation pad 14; the interlayer formed by the base film 11 and the middle 12 of the laminated films is filled with heat preservation particles 13, two adjacent wavy laminated films 12 form a ventilation opening 15 through a porous ventilation pad 14, and the direction of the ventilation opening 15 faces the ground. Wherein the porous air permeable mat 14 is a porous sponge.
Specifically, the knitted mesh-like carrier film 11 is knitted by 4-needle method. The insulating particles 13 are transparent PE particles.
Specifically, the top of the greenhouse film 1 is connected through an upright lock joint 2 and is covered on a greenhouse framework.
More specifically, the average thickness of the greenhouse film 1 was 0.5cm, the width of the wavy film 12 was 5cm, and the average particle diameter of the insulating particles 13 was 0.3cm.
