Problems solved by technology

However, there is still a considerable gap compared with foreign developed countries and my country's agricultural development needs: the main reason is that there are few types of functional films and single functions. For foreign manufacturers such as Japan, South Korea, and the United States, their own independent research and development capabilities are weak, and foreign manufacturers occupy most of the domestic high-end market share

Abstract

The invention relates to a diffuse scattering polyethylene greenhouse membrane and a preparation method thereof. The diffuse scattering polyethylene greenhouse membrane comprises an outer layer, a middle layer and an inner layer. The outer layer is a greenhouse membrane dripping layer, the middle layer is a greenhouse membrane thermal insulation layer and the inner layer is a greenhouse membrane long-life layer. The outer layer contains 6-7wt% of diffuse scattering master batches. The middle layer contains 2-3wt% of diffuse scattering master batches. The inner layer contains 1-2wt% of diffusescattering master batches. The diffuse scattering polyethylene greenhouse membrane has a dripping function and a diffuse scattering function and has a life the same to that of the agricultural membrane. The preparation method of the diffuse scattering polyethylene greenhouse membrane is scientific, reasonable, simple and easy.

Description

technical field [0001] The invention belongs to the technical field of agricultural film preparation, and in particular relates to a diffuse scattering polyethylene greenhouse film and a preparation method thereof. Background technique [0002] At present, the production and consumption of plastic agricultural film in my country ranks among the top in the world, and it is rapidly changing from ordinary agricultural film to functional functional film. However, there is still a considerable gap compared with foreign developed countries and my country's agricultural development needs: the main reason is that there are few types of functional films and single functions. For foreign manufacturers such as Japan, South Korea, and the United States, their own independent research and development capabilities are relatively weak, while foreign manufacturers occupy most of the domestic high-end market share. The "vegetable basket" project is an important way to increase farmers' incom...
