Problems solved by technology

However, ordinary polyethylene agricultural film is easy to break and break after being used for a period of time, and it is difficult to decompose itself, which seriously damages the soil quality and causes new white pollution of farmland. Therefore, the research on degradable plastic film has attracted great attention. Various degradable mulches
Liquid mulch has attracted people's attention due to its good degradation performance, low cost, and the ability to spray on-site to form a film. However, the domestic liquid mulch has a single variety, strong regional restrictions, simple functions, and relatively high production costs. In addition, the current There is not yet an environmentally friendly agricultural soil surface liquid film technology in some technologies

preparation example Construction

[0024] The preparation method of environment-friendly multifunctional agricultural soil surface liquid film of the present invention, described method comprises the following steps:

[0025] 1) Add the graded asphalt into the asphalt heating barrel of the emulsifier and heat it to 130-170°C, while stirring the asphalt, and heating for 2-3 hours;

[0026] 2) Mix the polymer emulsifier and water to form a soap liquid, place the soap liquid in the emulsifier heating barrel of the emulsifier and heat it to 85-120°C, adjust the pH value of the cationic soap liquid to 7.5, and the pH value of the anionic soap liquid Value is 9.0;

[0027] 3) Using the high-speed pump of the emulsifier, turn on the switch of the asphalt heating barrel and the emulsifier heating barrel to the direction of the mixing pump at a speed of 9000 rpm, fully mix the asphalt and soap liquid, and prepare a liquid film from the mixing pump stock solution;

[0028] 4) When applying, dissolve the liquid film sto...

Embodiment 1

[0031] 1) Take 3,000 grams of national standard No. 90 solid asphalt, put it in the asphalt heating barrel of the emulsifier and heat it to 130°C, stir the asphalt continuously while heating, and heat for 2.5 hours;

[0032] 2) Take 30 grams of slow-cracking cationic asphalt emulsifier and 2400 grams of deionized water, mix them in the emulsifier heating tank in the emulsifier to obtain soap liquid, heat to 85 ° C, keep stirring during the heating process, and adjust the soap The pH of the solution is 7.5.

[0033] 3) Start the high-speed mixing pump of the emulsifier, and when the speed of the mixing pump reaches 90,000 rpm, turn on the switch of the asphalt heating barrel and the emulsifier heating barrel to the direction of the mixing pump at the same time, and prepare the liquid film stock solution from the mixing pump;

[0034] 4) When applied in farmland, mix the liquid film stock solution with water at a volume ratio of 1:4, and then use a sprayer to spray evenly on the...

Embodiment 2

[0036] 1) Take 3000 grams of national standard No. 95 solid asphalt, put it in the asphalt heating barrel of the emulsifier and heat it to 150 ° C, and keep stirring the asphalt while heating, and heat for 2 hours;

[0037] 2) Take 30 grams of slow-cracking anionic asphalt emulsifier and 1290 grams of deionized water, mix them in the emulsifier heating tank in the emulsifier to obtain soap liquid, heat to 105 ° C, keep stirring during the heating process, and adjust the soap The pH of the solution is 9.0.

Abstract

The invention relates to an environment-friendly multi-functional agricultural soil surface nutrient film and a preparation method thereof. The environment-friendly multi-functional agricultural soil surface nutrient film consists of the following components in percentage by weight: 55 to 70 percent of mark asphalt, 0.5 to 0.8 percent of polymeric emulsifier and 22.5 to 44.2 percent of water; and the preparation method for the environment-friendly multi-functional agricultural soil surface nutrient film comprises the following steps of: 1) heating the mark asphalt in an asphalt heating barrel of an emulsifying machine to the temperature of between 130 and 170DEG C; 2) heating liquid soap prepared by mixing the polymeric emulsifier and the water in an emulsifier heating barrel of the emulsifying machine to the temperature of between 85 and 120DEG C, and regulating the pH value to be 7.5-9.0; 3) fully mixing the asphalt and the liquid soap by using a high speed pump of the emulsifying machine, and preparing film stock solution in a mixing pump; and 4) during application, dissolving the film stock solution and water in a ratio of 1:4 for mixing, uniformly stirring, and spraying the film on the earth surface by using a film sprayer to obtain the agricultural soil surface film.

Description

technical field [0001] The invention relates to a soil surface liquid film, in particular to an environment-friendly multifunctional agricultural soil surface nutrient liquid film and a preparation method, belonging to the technical field of agricultural mulch films. Background technique [0002] The use of agricultural plastic film cultivation technology has become one of the top ten agricultural technologies well known in the last century. The application of plastic film can better meet the water, fertilizer, air, heat, light and other factors required for crop growth and development, and achieve the needs of early maturity and increased production. However, ordinary polyethylene agricultural film is easy to break and break after being used for a period of time, and it is difficult to decompose itself, which seriously damages the soil quality and causes new white pollution of farmland. Therefore, the research on degradable plastic film has attracted great attention. A wid...
