Abstract

The invention discloses a dimming film capable of promoting normal growth of crops in a greenhouse. The dimming film comprises an inner layer, a secondary inner layer, a middle layer, a secondary outer layer and an outer layer, wherein the secondary inner layer is arranged on the outer side of the inner layer, the middle layer is arranged on the outer side of the secondary inner layer, the secondary outer layer is arranged on the outer side of the middle layer, and the outer layer is arranged on the outer side of the secondary outer layer. The dimming film capable of promoting the normal growth of the crops in the greenhouse is prepared from the following raw materials in parts by mass: 56-78 parts of PE, 40-60 parts of EVA, 15-25 parts of a constant temperature sodium agent, 12-18 parts of metallocene, 5-10 parts of a light stabilizer, 2-8 parts of an antioxidant material, 4-6 parts of a dripping agent, 5-8 parts of an antifogging agent, 3-10 parts of a nano rare earth metal complex and 1.5-4.5 parts of a binder. The dimming film capable of promoting the normal growth of the crops in the greenhouse has the beneficial effects that by adding the high-tech nano rare earth metal complex into the film, the haze value of the film is automatically increased when temperature in the greenhouse is too high,, scattered light in the greenhouse is increased, direct light is reduced, and the situation that the crops in the greenhouse are burnt due to too much direct light and too high temperature in the greenhouse is avoided.

Description

technical field [0001] The invention relates to the technical field of dimming film preparation, in particular to a dimming film capable of promoting normal growth of crops in a greenhouse and a preparation method thereof. Background technique [0002] Polymer dispersed liquid crystal (PDLC) is a liquid crystal dimming film, which is a film material with excellent comprehensive performance obtained by combining liquid crystal and polymer. At present, the existing dimming film is generally composed of two conductive ITO films and two The composition of the polymer-liquid crystal mixed layer between layers of conductive ITO films is prepared by coating and pressing. [0003] During the planting process of crops, film is usually used to cover and protect crops, but the existing ordinary film greenhouses cannot automatically adjust the direct light, which may easily burn the crops in the greenhouse and affect the growth of crops. [0004] Aiming at the problems in the related t...
