Problems solved by technology

However, there are some problems in the use of the existing film. For example, the infrared radiation energy injected into the ground in the greenhouse during the day is lost through the film at night, which greatly reduces the temperature of the greenhouse.

Embodiment 1

[0015]

[0016] Firstly, the above-mentioned raw materials in parts by weight were added to the mixer and stirred for 30 minutes, and the temperature of the mixer was kept at 95°C. Then, the homogeneously mixed material was added to a storage tank at 90° C. and allowed to stand for 30 minutes. Finally, the film was formed by dip coating with a coating machine, and the dip coating temperature was controlled at 80 °C.

Abstract

The invention relates to a heat insulation and preservation plastic film. The heat insulation and preservation plastic film is prepared from the following raw materials in parts by weight: 80-100 parts of polyethylene resin, 15-20 parts of an inorganic infrared heat insulation and preservation agent, 20-30 parts of a dripping agent, 1-5 parts of a dispersant, 1-5 parts of an aromatic amine antioxidant, 1-5 parts of a Ca / Zn composite stabilizer and 2-3 parts of a fog reducing agent. The heat insulation and preservation plastic film provided by the invention has high strength and good performance, can prevent a large amount of infrared rays from entering a greenhouse in the daytime and play a role in insulating heat and can prevent energy from dissipating in the nighttime and play a role in preserving heat.

Description

technical field [0001] The invention relates to the field of plastic films, in particular to a thermal insulation plastic film. Background technique [0002] my country's demand for agricultural plastic film is huge. In recent years, the average annual consumption is more than 1.1 million tons, which is the main means of production in agricultural production. However, there are some problems in the use of the existing film, such as the infrared radiation energy injected into the ground in the greenhouse during the day and lost through the film at night, which greatly reduces the temperature of the greenhouse. On the other hand, a large amount of infrared rays enter the shed, especially at noon, which makes the shed temperature too high and burns the crops. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a heat-insulating plastic film, which avoids the phenomenon that the temperature in the shed is too high to ...
