Problems solved by technology

[0005] 2) Due to the large amount of dust particles in the air, a layer of dust will be deposited on the surface of the agricultural film as the use time of the agricultural film increases, which seriously affects the light transmission performance of the agricultural film and reduces the crop yield
However, at night, the heat in the soil will be released slowly, and after passing through the agricultural film,

Abstract

The invention provides a multifunctional agricultural thin film and a preparation method thereof. The multifunctional agricultural thin film comprises the following components in part by weight: 100 parts of resin, 1 to 5 parts of microencapsulated mouse-proof and insect-proof agent, 5 to 10 parts of nano particles A, 2 to 5 parts of nano particles B, 0.2 to 0.5 part of antioxygen, 0.1 to 0.25 part of light stabilizer and 20 to 40 parts of filler, wherein the microencapsulated mouse-proof and insect-proof agent consists of a capsule core and a capsule covering the capsule core; the capsule core is made of more than one of capsaicine, capsaicine derivative, N-ethyl-2-(isopropyl)-5-methylcyclohexanecarboxamide or N-ethyl-2-(isopropyl)-5-methylcyclohexanecarboxamide derivative; and the capsule is made of melamine formaldehyde resin with a particle size of 35 to 55 mu m. The preparation method disclosed by the invention is simple and efficiency, and the agricultural thin film has good mouse-proof, insect-proof, self-cleaning and diffuse-reflection effects; meanwhile, the production cost is lowered, the service life of the agricultural thin film is prolonged, and the application range of the agricultural thin film is enlarged.

Description

technical field [0001] The invention relates to a multifunctional agricultural film and a preparation method thereof. Background technique [0002] Agricultural film plays a very critical role in agricultural production. It has the effect of heat preservation and moisturizing, and can greatly increase the output of grain. However, in daily life, agricultural film will have the following problems: [0003] 1) During the use or storage of agricultural film, it will inevitably be harmed by rats and pests. This will not only cause damage to the agricultural film itself, but also cause large and small holes on the surface, which will cause the agricultural film to lose its thermal insulation performance and cause indirect crop yield reduction; and when mice and pests enter the greenhouse, they will directly gnaw Eat crops, resulting in a direct reduction in production. [0004] At present, the method of adding insecticides is mainly used in agricultural films to obtain the abi...
