Problems solved by technology

This method is to mix functional substances with polyethylene first and then perform high-temperature (200°C) blow molding. Since some functional substances cannot withstand high temperatures, the function of the film is limited, the process is complex, labor-intensive, and pollution is also large; One is a double-layer film. The method is to put functional substances between the two layers of film, and then heat-rolled to make it a composite layer. Although the function of the single-layer film is increased, the double-layer film is only tight Only after the layer of film on the ground is broken, the functional substances in it can play a role, which greatly reduces the efficiency of the functional substances, and the process is difficult, wasteful and costly
Foreign reports use acrylic smearing method, which is only used to make anti-drip film and has no other functions

Embodiment 1

[0016] Add 100g of polyethylene emulsion to 1g of urea, 1g of potassium dihydrogen phosphate, 0.05g of magnesium sulfate, 0.025g of ferrous sulfate, 0.01g of zinc sulfate, 0.05g of boric acid, 0.01g of copper sulfate, and 0.005g of ammonium molybdate and mix them evenly. Spread the above mixture on a 1 square meter polyethylene mulch film, dry it at room temperature or blow it with hot air to form a mulch film with fertilizer function;

Embodiment 2

[0018] Mix 100g of polyethylene emulsion, add 0.8g of Promethazine, and 0.1g of micro-fertilizer, and then apply the above-mentioned mixture on a 1 square meter polyethylene mulch film, and blow dry at room temperature or hot air to form a film. And the mulch with micro-fertilizer function.

Embodiment 3

[0020] Mix 100g of oxidized polyethylene emulsion, add 2g of grass Wandi, 0.5g of carbon black, and 0.1g of fertilizer. Then apply it on a 1 square meter polyethylene mulch film, dry it at room temperature or hot air to form a film, it becomes a black mulch film with herbicidal and micro-fertilizer effects.

Abstract

The invention discloses an agricultural multifunctional emulsion composite plastic film and a composite method. The composite method comprises the steps of adding functional materials (fertilizer, pesticide, pigment) into polyolefin emulsion, stirring uniformly, spraying or smearing the mixed emulsion (filming material) on polyethylene film, in normal temperature blow-drying with hot air to become the composite film. The agricultural multifunctional emulsion composite plastic film has the advantages of being multifunctional, convenient to promote and use, low in cost, fast in effectiveness, and huge in economic benefits.

Description

Technical field [0001] The invention relates to a mulching film, in particular to an agricultural multifunctional emulsion composite mulching film and a composite method. Background technique [0002] At present, one of the mulch films used at home and abroad is a single-layer film, which adopts high temperature blow molding. This method is to mix functional materials with polyethylene and then blow molding at a high temperature (200°C). Because some functional materials cannot withstand high temperatures, the function of the mulch film is limited, the process is complicated, the labor intensity is high, and the pollution is large; One is a double-layer film. The method is to put a functional substance between the two layers of film, and then heat it to form a composite layer. Although it has more functions than a single-layer film, the double-layer film is only tight. After a layer of film on the ground is broken, the functional substances can play a role. This greatly reduces ...
