Abstract

The invention discloses an anti-aging anti-fogdrop greenhouse film and a preparation method thereof. The anti-aging anti-fogdrop greenhouse film is prepared from the following components in parts by mass: 60-80 parts of polyethylene, 0.1-0.9 part of triphenyl phosphite, 0.15-0.2 part of dilauryl thiodipropionate, 0.05-0.18 part of 6-ethoxy-2,2,4-trimethyl-1,2-dihydroquinoline, 3-6 parts of sodium alkyl benzene sulfonate, 1-4 parts of polyvinylpyrrolidone, 1-3 parts of dioctyl sulfodibutyrate and 0.1-0.5 part of antioxidant. The polyethylene is prepared by mixing LDPE (low-density polyethylene) and LLDPE (linear low-density polyethylene) according to a mass ratio of (6-8):1. The antioxidant is antioxidant 1010 or antioxidant DLPP. The greenhouse film has long anti-aging time, and does not need to be replaced within three years; the anti-fogdrop effective time of the greenhouse film is up to 900 hours; and thus, the greenhouse film has wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to an anti-aging and anti-fog droplet greenhouse film and a preparation method thereof. Background technique [0002] As the covering material of the greenhouse, the greenhouse film isolates the crops from the external environment, so that the crops are in a relatively closed and controllable growth environment. Through the greenhouse covering material, the exchange and circulation of energy (light, heat) and substances (water, air fertilizer, etc.) between the indoor or shed environment where crops are grown and the external environment are constantly carried out, and the two influence each other. interaction. Therefore, the greenhouse covering material is one of the most important components in the greenhouse. The varieties and characteristics of the greenhouse covering material directly affect the growth of crops in the greenhouse. The selection of g...
