Problems solved by technology

Some chemicals will seriously affect the service life of the agricultural film, especially the pesticides containing chlorine, which will destroy the quality and safety of the agricultural film. What's more, if the greenhouse is smoked with sulfur, the sulfide in the gas produced Seriously reduce the service life of agricultural film
The agricultural film is exposed to high temperature for a long time, and it is also particularly prone to aging and damage

Abstract

The invention discloses a master batch for preparing an agricultural film with 5-year super long service life. The master batch is characterized by being prepared from the raw materials in percentage by weight: 15-25 percent of light stabilizer HS-44, 1-3 percent of pesticide tolerant light stabilizer T-68, 2-7 percent of antioxidant B215, 1-4 percent of ultraviolet absorbent UV531, 45-60 percent of polyethylene LLDPE (Linear Low Density Polyethylene) powder and 10-20 percent of polyethylene LLDPE. A greenhouse film prepared from the master batch has strong pesticide resistance, high thermal stability and long service life; and with the adoption of the greenhouse film, the problem about the service life of the agricultural film is solved, and the quality of the agricultural film is improved.

Description

technical field [0001] The invention discloses a method for preparing plastic masterbatches, in particular to a method for manufacturing masterbatches produced by agricultural greenhouse films. Background technique [0002] The production of masterbatch is a key link in the production of agricultural film. The function of masterbatch directly affects the quality and life of agricultural film. The service life of the agricultural film is related to the local climate conditions, because the higher the altitude, the stronger the intensity of ultraviolet radiation, and the service life of the agricultural film will be greatly shortened. Some chemicals will seriously affect the service life of the agricultural film, especially the pesticides containing chlorine, which will destroy the quality and safety of the agricultural film. What's more, if the greenhouse is smoked with sulfur, the sulfide in the gas produced Seriously reduce the service life of agricultural film. Agricultu...
