Abstract

The invention relates to the field of agricultural functional materials, and discloses a preparation method of a sunshade net with a self-cleaning function. The preparation method comprises the following steps: dissolving soluble zinc salt, sodium citrate, sodium acetate, soluble copper salt and silver nitrate in ethylene glycol to prepare a solution, adding a titanium source, keeping the temperature at 150-250 DEG C for 8-16 hours, cooling to the room temperature after the reaction is finished, separating out a solid product, washing, and calcining at 400-600 DEG C for 2-5 hours to obtain a composite titanium dioxide photocatalyst; wherein the molar ratio of the soluble zinc salt to the sodium citrate to the sodium acetate to the soluble copper salt to the silver nitrate to the titanium source is (10-20): (1-3): (25-40): (0.5-2): (0.5-2): (30-60); uniformly mixing polyethylene particles and the composite titanium dioxide photocatalyst according to a mass ratio of (100-200): 1, and adding the mixture into a wire drawing machine for wire drawing to obtain self-cleaning polymer fibers; and weaving the self-cleaning polymer fibers into the sunshade net with a self-cleaning function ina visible light area by a net weaving machine.

Description

technical field [0001] The invention belongs to the field of agricultural functional materials, and in particular relates to a method for preparing a sunshade net with self-cleaning function. Background technique [0002] Self-cleaning materials can achieve the purpose of saving energy and water. Therefore, the research and development of self-cleaning materials has attracted people's attention. At present, the self-cleaning of fabrics is mainly realized by two technologies: superhydrophobic surface and photocatalytic self-cleaning. Among them, the photocatalytic technology is to load materials with photocatalytic effect on the fabric to realize the self-cleaning of the fabric. Titanium dioxide, a commonly used photocatalyst, is widely used in the field of photocatalysis due to its good photocatalytic activity, non-toxicity, good biocompatibility and low price. However, the band gap region of titanium dioxide is mainly in the ultraviolet region, resulting in a low photoca...
