Embodiment 1

[0024] A polyethylene plastic greenhouse cloth, the greenhouse cloth is a three-layer composite structure, the three-layer composite structure includes an outer layer, a middle layer and an inner layer; the outer layer and the inner layer are both high-pressure low-density polyethylene coating layers; the middle layer is a low-pressure High-density polyethylene woven cloth.

[0025] The outer layer in this embodiment includes the following components in parts by mass: 80 to 90 parts of polyethylene, 10 to 20 parts of an anti-aging mixture containing an infrared blocking agent; the middle layer includes the following components in parts by mass: polyethylene 92 ~100 parts, anti-aging agent 2-6 parts; the inner surface layer includes the following components in mass parts: 83-89 parts of polyethylene, 11-17 parts of anti-aging mixture containing anti-fogging agent.

[0026] The greenhouse cloth of the present invention has a three-layer composite structure, high strength, good w...

Embodiment 2

[0028] This embodiment is basically the same as Embodiment 1, the difference is:

[0029] The outer layer includes the following components in parts by mass: 86 parts of polyethylene, 14 parts of anti-aging mixture containing infrared blocking agent.

Embodiment 3

[0031] This embodiment is basically the same as Embodiment 1, the difference is:

[0032] The middle layer includes the following components in parts by mass: 96 parts of polyethylene and 4 parts of anti-aging agent.

Abstract

The invention discloses polyethylene plastic greenhouse cloth and a preparation method thereof and relates to the technical field of plastic weaving. The greenhouse cloth is of a three-layer compositestructure; the three-layer composite structure comprises an outer surface layer, a middle layer and an inner surface layer; the outer surface layer and the inner surface layer are high-pressure low-density polyethylene coating layers; and the middle layer is low-pressure high-density polyethylene woven cloth. Since the greenhouse cloth disclosed by the invention is of the three-layer composite structure, the greenhouse cloth is high in strength, excellent in weather resistance, difficult to tear and wear, excellent in transparency, slow in attenuation, long in service life and excellent in anti-fog, anti-drop infrared blocking thermal insulation effect, so that the problems that the conventional plastic greenhouse film is low in strength, easy to tear and wear, poor in transparency, fastin attenuation and frequent to replace and lots of plastic wastes are produced are solved, and the polyethylene plastic greenhouse cloth in the invention is environment-friendly, time-saving and labor-saving. Moreover, the preparation method disclosed by the invention is simple in process step and low in cost, so that the greenhouse cloth disclosed by the invention can be produced on a large scale.

Description

technical field [0001] The invention relates to the technical field of plastic weaving, in particular to a polyethylene plastic greenhouse cloth and a preparation method thereof. Background technique [0002] Traditional plastic greenhouses mostly use polyethylene plastic film. This polyethylene plastic film has the disadvantages of poor strength and poor weather resistance. When in use, it is prone to problems such as tearing, abrasion, rapid decrease in light transmittance, and short service life. After the polyethylene plastic film is used, it needs to be replaced every year, which causes waste, increases the cost of farmers, and pollutes the environment. Contents of the invention [0003] In view of the above-mentioned deficiencies, the purpose of the present invention is to provide a polyethylene plastic greenhouse cloth and its preparation method, the polyethylene plastic greenhouse cloth has the advantages of high strength, anti-drip, anti-fog and blocking infrare...
