Abstract

The invention discloses starch-polyamide anti-aging and anti-fogging greenhouse film and a preparation method thereof. The starch-polyamide anti-aging and anti-fogging greenhouse film is prepared from, by weight, 50-60 parts of polyamide, 8-15 parts of calcium carbonate, 1-4 parts of nano-titanium dioxide, 10-20 parts of triphenyl phosphate, 7-9 parts of sodium alkyl benzene sulfonate, 1.2-1.4 parts of tetrabutyl titanate, 12-14 parts of chitosan, 60-65 parts of corn starch, 2-3 parts of gelatin, 1-2 parts of magnesium stearate, 13-15 parts of acetyl tributyl citrate, 1-1.5 parts of 2,6-di-tert-butyl-4-methylphenol, 4-6 parts of 3-hydroxybenzoic acid, 1-2 parts of polyvinyl pyrrolidone and 4-6 parts of plant saponin. According to the greenhouse film prepared from the materials, the anti-aging time is long, the film does not need to be replaced in three years after being arranged on a greenhouse in a covering mode, the effective anti-fogging time of the greenhouse film reaches up to 900 h, and a wide application prospect is achieved.

Description

technical field [0001] The invention relates to the technical field of plastic films, in particular to a starch-polyamide anti-aging and anti-fogging drop 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 materials, the indoor or shed environment where the crops grow is constantly exchanging and circulating energy (light, heat) and substances (water, gas fertilizer, etc.) with the external environment, and the two influence each other. interaction. Therefore, the greenhouse covering material is one of the most important components in the greenhouse. The variety and characteristics of the greenhouse covering material directly affect the growth of the crops in the greenhouse. The selection of greenhouse covering materials...
