Abstract

Provided is a nanometer material modified polyethylene agricultural film in the polyethylene technical field. which comprises following components in mass ratio: 91.5-99.3 parts of polyethylene resin,0.2-1.5 parts of inorganic nanocomposite, 0.1-1 part of antioxidant, 0.1-1 part of light stabilizing agent and 0.3-5 parts of processing auxiliary agent. The provided agricultural film has excellentphysical and mechanical performance and weatherability and can be produced into high quality agricultural warmhouse booth film.

Description

technical field [0001] The invention relates to a film in the technical field of nanometer materials and a preparation method thereof, in particular to a nanometer material modified polyethylene agricultural film and a preparation method thereof. Background technique [0002] With the development of agriculture, agricultural plastics have become an essential and important means of production to promote more efficient agricultural development. From the cold winter to the early spring in northern my country, the sunshine time is short and the atmospheric temperature is low. In order to increase the crop yield, the demand for agricultural greenhouse films with excellent performance continues to increase. Traditional agricultural greenhouse films mainly use polyvinyl chloride resin as raw material. Although polyvinyl chloride film is more resistant to weathering and aging, it contains a large amount of plasticizer. During processing and use, the plasticizer volatilizes and the ...
