Problems solved by technology

However, since most of the mulch films are made of polyethylene or polyvinyl chloride, their stability is extremely high, and the degradation process is quite slow, which has caused serious white pollution.
In order to solve this problem, driven by the development of science and technology, a variety of degradable mulch films have been gradually developed, mainly using one or more of humic acid, emulsified asphalt, polyvinyl alcohol, polyacrylate and their polymers. Main raw materials, such as Chinese patent CN102533276A discloses the production of degradable liquid plastic film with montmorillonite and humic acid, and humic acid is used as the main raw material to solve the pollution of plastic film to the land environment; Chinese patent CN1277228A discloses a multifunctional degradable black liquid plastic film Mainly use petroleum asphalt or residual oil as raw materials, the cost is high, and the source of raw materials is limited to a certain extent. In addition, when the substance is diluted, it is easily emulsified when it encounters hard water, resulting in a decrease in film formation; Chinese patent CN1935878A di

Abstract

The invention belongs to the technical field of an agricultural thin film, and discloses a preparation method of a full-degradable soil moisture preservation agricultural mulching film. The agricultural mulching film is prepared from the following raw materials in parts by weight: 20 to 40 parts of poly-hydroxyalkanoate polymers, 8 to 15 parts of fatty ester condensation polymers, 20 to 30 parts of sea algae extracts, 100 to 150 parts of n-hexane, 30 to 40 parts of okra straw and leaf powder, 5 to 10 parts of corn stigma, 3 to 5 parts of modified clay powder, 10 to 15 parts of film forming agents, 5 to 12 parts of cross linking agents, 3 to 5 parts of photosensitizers and 8 to 15 parts of optional functional auxiliary agents. The mulching film provided by the invention has the advantages that the film forming effect on the ground surface is good; the speed is high; the automatic full degradable effect can be achieved; the effects of soil moisture preservation and temperature rise can be achieved; the functions of improving the soil structure and improving the soil fertility are realized.

Description

Technical field: [0001] The invention belongs to the technical field of agricultural film preparation, and relates to a preparation method of plastic film spraying, in particular to a preparation method of a fully degradable soil moisture retention film. The prepared agricultural plastic film can be used in agricultural occasions to adjust and protect soil moisture. Improve crop development ability. Background technique: [0002] The application of plastic film can meet the needs of crop heat preservation, moisture conservation, and fertility maintenance to increase production and income, and has been widely promoted and applied. It has become an important technology for increasing agricultural production. However, since most of the mulch films are made of polyethylene or polyvinyl chloride, their stability is extremely high, and the degradation process is quite slow, which has caused serious white pollution.
