Abstract

The invention provides a degradable heat-preservation mulching film containing cow dung. The degradable heat-preservation mulching film is prepared from the following raw materials: a cow dung base material, pullulan, polyether modified organic silicon and propylene glycol methyl ether acetate. A preparation process comprises the following steps: killing ova and bacteria in the cow dung; removingsand and removing impurities; carrying out solid-liquid separation; grinding; blending a base material; spraying a film and molding. The mulching film disclosed by the invention can be used for replacing a plastic mulching film to carry out agricultural planting; pollution-free organic fertilizer, which is easily absorbed by plants, can be formed by utilizing rapid post-decomposition and corrosion, and white and toxic pollution of an inorganic mulching film is reduced or avoided; the degradable heat-preservation mulching film has remarkable economic benefits and social benefits and has a goodapplication prospect.

Description

technical field [0001] The invention relates to the field of agricultural tools, in particular to a low-cost, degradable agricultural degradable thermal insulation film containing cow dung and a manufacturing method thereof. Background technique [0002] The development of mulch film technology and the use of mulch film in my country started in the 1970s. Although it was 20 years later than developed countries, it developed rapidly. At present, the coverage area of ​​mulch film ranks first in the world, and the usual amount of agricultural mulch film is used. It reaches more than 1 million tons per year, and is continuing to develop at a higher rate. The agricultural films currently used in our country are basically monomeric polyethylene films, which have caused serious "white pollution" when used in large quantities. In order to solve the "white pollution" problem caused by ordinary plastic films, scientists put forward the concept of degradable plastics in the 1970s. Usin...
