Problems solved by technology

[0002] Greenhouse film is widely used in the agricultural field. At present, when using the greenhouse film on the market, it needs to be covered with straw mats or use heating equipment in the greenhouse to keep the temperature in the greenhouse constant. This is very inconvenient for farmers to grow vegetables. In frosty weather, for some vegetables or fruits that are not resistant to cold, farmers need to spend time and effort to heat them in the greenhouse. A slight delay in the processing process may result in reduced or no harvest of vegetables or fruits in the greenhouse, which brings farmers big trouble

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.
