Example Embodiment
[0023] Example one:
[0024] A kind of polyethylene plastic greenhouse fabric. The greenhouse fabric is a three-layer composite structure. The three-layer composite structure includes an outer surface layer, a middle layer and an inner surface layer; the outer surface layer and the inner surface layer are both high-pressure low-density polyethylene coating layers; the middle layer is low-pressure High-density polyethylene woven fabric.
[0025] The outer surface layer in this embodiment includes the following components by mass: 80 to 90 parts of polyethylene, and 10-20 parts of anti-aging mixture containing infrared blocking agent; the middle layer includes the following components by mass: 92 ~100 parts, 2-6 parts of anti-aging agent; the inner surface layer includes the following parts by mass: 83-89 parts of polyethylene, 11-17 parts of anti-aging mixture containing anti-fogging agent.
[0026] The greenhouse fabric of the present invention has a three-layer composite structure,...
Example Embodiment
[0027] Embodiment two:
[0028] This embodiment is basically the same as the first embodiment, but the difference lies in:
[0029] The outer surface layer includes the following components in parts by mass: 86 parts of polyethylene, and 14 parts of anti-aging mixture containing infrared blocking agent.
Example Embodiment
[0030] Embodiment three:
[0031] This embodiment is basically the same as the first embodiment, but the difference lies in:
[0032] The middle layer includes the following components in parts by mass: 96 parts of polyethylene and 4 parts of anti-aging agent.
