Problems solved by technology

Although the patent application "A Montan Wax Resin Activation Modification Solution and Its Production Method and Application" provided a very advantageous agricultural utilization method and field for montan wax resin, in view of the research level and experience level at that time, the application Technology still has significant limitations
First of all, the proportion of the resin degraded to form the modified liquid is less than 40% of the original resin, which means that most of the resin cannot be effectively used after being processed by this technology; secondly, the used composite oxidant or its reaction product is left in the There is no benefit in the modified solution, and even adverse effects, such as excessive acetic acid (reduced product of peracetic acid) in the modified solution will lead to high acidity of the solution, which does not take advantage of its application in the agricultural field; also, the Applied technology does not provide a specific and large-scale use of modified liquid in the agricultural field, which is one of the key factors for whether it can be truly utilized in agricultural production
To sum up, there is still a big gap in the effective utilization of montan wax resin, an industrial "waste" in the agricultural field, only relying on the existing technology

Abstract

The invention discloses a Montan wax resin multifunctional liquid mulching film and a preparation method thereof, and belongs to the technical field of agriculture. The liquid mulching film is prepared from Montan wax resin, a resin cosolvent, potassium permanganate, polyvinyl alcohol, triethanolamine and other substances. The liquid mulching film provided by the invention not only has the generalfunctions of water retention and warming, but also can have the effects of regulating the growth of crops and promoting yield increment of the crops; through the resin oxidation modification process,the method uses the Montan wax resin to prepare the high value-added product used in agriculture for the first time, and the method provides a high-efficiency usage manner suitable for large-scale application for the industrial ''waste'', and also provides the innovative product used in the agriculture for yield increment and income increment of agriculture; and the main raw materials of the mulching film are cheap, the production technological process is simple, energy-saving and environmentally friendly, and the liquid mulching film is convenient for industrialization, promotion and application, and has good market prospects.

Description

technical field [0001] The invention relates to a montan wax resin multifunctional liquid mulching film and a preparation method thereof, belonging to the technical field of agriculture. Background technique [0002] Liquid mulch is a kind of film-forming material that is prepared into a liquid state. After spraying, a gel-like film is formed on the soil surface to connect soil particles and play the role of a mulch. The use of liquid mulch can make the soil surface form a multi-molecular network film, which can close the pores on the soil surface and inhibit the volatilization of soil water, but does not affect the infiltration of water. At the same time, the dispersed soil particles can be cemented together to form a soil aggregate structure. . Liquid mulch generally has advantages over biodegradable mulch, photodegradable mulch, and other degradable mulches in terms of processing and preparation, performance, and degradation, and is easy to promote and use on a large sca...
