The light transmittance and the temperature difference of the film have important application values for the agricultural field, the biological field and the like.
Accordingly, in order to address the above-mentioned drawbacks, it is desirable to provide a film having good light transmittance and heat insulating properties.

In the invention, a small amount of potassium laurate and polyoxyethylene dodecyl ether are used as active agents, so that the mixing state in the preparation process can be effectively blended, a good mixing effect can be achieved for some particles, and the improvement of light transmittance is facilitated.
Preferably, the raw materials for preparing the polyethylene temperature difference film with high light transmittance further comprise 0.1-0.5 part of corrosion inhibitor, for example, 0.1 part, 0.2 part, 0.3 part, 0.4 part or 0.5 part, etc.
Preferably, the corrosion inhibitor is benzotriazole or pyridazine.

The implementation of the invention has the following beneficial effects:
according to the polyethylene temperature difference film with high light transmittance, the special light absorber and the light stabilizer are selected, so that the polyethylene resin has good light stability and good light transmittance, and meanwhile, most of incident light can be well absorbed, and absorbed corresponding energy can be blocked by the film, so that a good temperature difference effect is generated inside and outside the film. In addition, the film prepared from the film has a good contact angle by taking potassium laurate and polyoxyethylene dodecyl ether as an activating agent, so that the light transmittance of the film is improved. The light transmittance of the temperature difference film can reach more than 90%, and the highest irradiation temperature difference of a common light source can reach more than 20 ℃.
