Abstract
The invention relates to a constant-temperature self-cleaning agricultural greenhouse film and a production method thereof. The constant-temperature self-cleaning agricultural greenhouse film is of a four-layer structure and comprises an aging layer, an insulating layer, a self-cleaning layer and a dripping layer from the outside to the inside, wherein the four layers are all made of low-density polyethylene; and the insulating layer is a weaving layer formed by crossed warps and wefts. The greenhouse film has the advantages that 1) the greenhouse is made of the low-density polyethylene material, is waterproofing and flame-retardant, can resist radiation of ultraviolet ray, and is wearable and durable, lower in cost, better in performance, more stable in structure, degradable, green and environment-friendly without pollution; 2) the greenhouse film has a self-cleaning function due to the material of the self-cleaning layer; 3) the dripping layer is reasonable in prescription, and can constantly resist dripping and fog; 4) the aging layer has good weather resistance, and the service life of the aging layer can be 3-5 years; 5) the greenhouse can be kept at a constant temperature due to the good insulation effect; and 6) the production method is simple and easily operated, the whole production process does not have pollution or emission of the three wastes, and has remarkable economical and social benefits.
