Abstract

The invention relates to the field of liquid mulch films, and in particular relates to a liquid mulch film containing micro nano micro silica fume suspension matter. The mulch film comprises the following components in percentages by weight: micro nano micro silica fume, a thickening agent, polyvinyl alcohol, a dispersant, a nitrogen fertilizer, and water. The mulch film provided by the inventionhas the advantages that microelements necessary for growth are provided for plants; the production costs are low, the preparation process is simple, and space can be effectively saved during production and transportation; the mulch film is convenient for use, and has excellent water-retention heat-insulation effects, good film forming performance after being used, and no cracking after being dried; the components contained in the mulch film are uniformly suspended in the liquid, the preservation time is long, and no delamination phenomena appear; and the mulch film has no side effects on vegetations and environments.

Description

Technical field [0001] The invention relates to the field of liquid mulching films, in particular to a liquid mulching film containing micro-nano micro-silica powder suspension and a preparation method thereof. Background technique [0002] Since the concept of liquid mulch film was put forward in the 1970s, the development of liquid mulch film has not been interrupted. Suspended liquid mulch is a kind of organic-inorganic composite liquid mulch. The application of organic-inorganic composite materials can realize the performance of organic and inorganic materials. Complementary and synergistic. For example, the montmorillonite aluminosilicate and humic acid are modified to form a polymer under the action of a crosslinking agent and a film-forming agent, and then a variety of reagents are added to prepare a liquid film suspension with a certain film-forming property; Mixing methyl silicate, strong alkali, and water can produce a liquid mulching film suspension. The final product...
