Method for manufacturing agricultural film coated by high performance polyolefin

Abstract

The invention relates to an agricultural greenhouse and a greenhouse cover material, and concretely relates to a preparation method of high performance polyolefin by using a coating technology and a nano modification technology. The high performance polyolefin coating agricultural film takes high performance polyolefin as a matrix, a functional master batch is added to prepare a base material film, and the agricultural film can be prepared by preciously coating through a coating liquid; the high performance polyolefin coating agricultural film is prepared by processes of preparing the functional master batch, preparing a base material thin film, performing corona treatment, winding the base material film, coating one surface by the coating liquid, drying the coating liquid, cooling and winding, on-line roll change, coating on the other surface by the coating liquid. The flow-dripping period and the service life can reach more than three years, and the agricultural film has the advantages of good heat insulating ability, pesticide resistance property and dirt resistance property.

Description

technical field

[0001] The invention relates to a covering material for agricultural greenhouses and greenhouses, in particular to a preparation method for preparing a high-performance polyolefin (High Polyolefin) coated agricultural film through a coating process and nano-modification technology. Background technique

[0002] my country is a large agricultural production country, and agricultural film is an important means of production in my country's modern agriculture, especially functional agricultural film has played an important role in increasing agricultural production and income. my country's functional film coverage area has reached 30 million mu, ranking first in the world. However, compared with advanced countries, there is still a significant gap in the level of agricultural film in my country. , quality, function, application fields and other aspects can not meet the needs of modern agricultural cultivation technology. With the improvement of raw materials, ad...
