Abstract
The invention discloses a degradable liquid agricultural mulching film which is prepared from the following raw materials: corn starch, industrial alcohol, 52 aldehyde, film forming agent, emulsifying agent, chlorin agent, alcoholysate and water. The production process comprises the following steps of: firstly, adding 1/3 of water in the raw materials into a reaction tank, simultaneously adding the corn starch, heating while stirring, and insulating for about 30 minutes after the temperature rises to about 100 DEG C; adding 1/2 of the residual water into the reaction tank, stirring, adding the industrial alcohol after the temperature drops to about 60 DEG C, heating and stirring again, and insulating for 1 hour after the temperature rises to about 80 DEG C; adding the residual water into the reaction tank, stirring, adding the 52 aldehyde after the temperature drops to about 70 DEG C, stirring for about 30 minutes, and then insulating for about 30 minutes; and adding the film forming agent, emulsifying agent, chlorin agent and alcoholysate into the reaction tank, stirring, reacting for about 1 hour, and then stopping the reaction to obtain an oily liquid, namely the liquid agricultural mulching film.
Description
Technical field: the invention belongs to the agricultural mulching technical scope, relate to a kind of working method of liquid agricultural mulching film.
Background technology: plastic film mulching cultivation can be incubated soil moisture conservation, is the effective means of the precocious raising the output of farm crop.The wide popularization and application of film-mulching cultivation technique is for developing rapidly of agricultural brought into play enormous function.But present widely used Vilaterm solid mulch film is difficult to degraded, has caused huge white pollution.For overcoming this problem; All researching and developing degradable ground membrane technique both at home and abroad at present; For example Japan's development is the Biodegradable mulch of masterbatch with the regenerated cellulose; Germany development be that photodegradation film and China of masterbatch adds two degradative plastic films that treated starch processes or the like with the heat-sensitive resin in regenerated cellulose and heat-sensitive resin, overcome the above-mentioned drawback that existing polyethylene ground film is difficult to degrade effectively.But the production cost of above-mentioned degradable mulch is high especially, and inconvenience is accepted by vast farmers, is difficult to wide popularization and application.In addition, less in view of the area of effective coverage ratio of solid mulch film, often cause the problem of mulch film waste, therefore use conveniently, degradable liquid mulch film nuisanceless, that the area of effective coverage ratio is high just becomes the constantly direction of research and development of people.Application number is the patented claim of 01130944.X, discloses a kind of multifunctional hydrolyzed mulching liquid and blending process thereof.The hydrolyzed mulching liquid of this patented claim technology is made up of Z 150PH, ROHM, hydroxypropylated starch, sorbyl alcohol, Magnesium Stearate and urea raw material; Employing joins Z 150PH, ROHM, hydroxypropylated starch and sorbyl alcohol in the extrusion machine, passes through room temperature and is heated to 130 ℃, 130 ℃, 110 ℃, 110 ℃ and 150 ℃/30-40
Bzr6 temperature sections; Raw material after the extruding is added Magnesium Stearate, urea and terepthaloyl moietie more further be crushed to the fusion flocculation agent; In lixator, add quantitative water then, turn on agitator slowly is sprinkled into flocculation agent and makes.This hydrolyzed mulching raw material type is more, and cost is also than higher; The method of its preparation, program are comparatively loaded down with trivial details, and production efficiency is lower.
Summary of the invention: the purpose of this invention is to provide a kind of new liquid agricultural mulching film and working method thereof, in order to overcome the above-mentioned drawback of existing in prior technology effectively.The objective of the invention is to realize with following technical scheme:
