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 mulch is limited, the process is complicated, the labor intensity is high, and the 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. The functional substances in it can only play a role after the layer of film on the ground is broken, which greatly reduces the efficiency of the functional substances
The process is difficult, the waste is large, and the cost is high
[0003] Foreign reports use acrylic smearing method, which is only used to make anti-drip film and has no other functions

Embodiment Construction

[0017] 1. Polyethylene emulsion 100g, add urea 1g, potassium dihydrogen phosphate 1g, magnesium sulfate 0.05g, ferrous sulfate 0.025g, zinc sulfate 0.01g, boric acid 0.05g, copper sulfate 0.01g, ammonium molybdate 0.005g and mix evenly. Spread the above mixed solution on a polyethylene mulch of 1 square meter, dry it at room temperature or blow it with hot air to form a film, and then it becomes a mulch film with fertilizer function.

[0018] 2. Add 100g of polyethylene emulsion, add 0.8g of promethazine, 0.1g of micro-fertilizer and stir evenly, then apply the above mixed solution on 1 square meter of polyethylene film, dry it at room temperature or with hot air to form a film, and it will become Mulch with grass and micro-fertilizer function.

[0019] 3. Add 100g of oxidized polyethylene emulsion, add 2g of vanilla, add 0.5g of carbon black, add 0.1g of fertilizer and mix evenly. Then smear it on 1 square meter polyethylene mulch, and dry it at room temperature or hot air t...

Abstract

The invention provides an agricultural film and a preparation method thereof. The preparation method comprises the following steps: doping functional substances (fertilizers, pesticides and pigments) into a polyolefin emulsion, stirring uniformly, spraying or brushing the mixed emulsion (film forming matter) on a polyethylene mulching film, and carrying out normal-temperature or hot air drying to obtain the composite film. The film has the advantages of multiple functions, wide applicability, artificially adjustable functions and controllable release rate; and the normal-temperature spraying technique is simple and easy to implement, low in equipment investment and convenient for popularization and use. The agricultural film has the advantages of low cost, quick effect taking and obvious economic benefits, and is the most vigorous agricultural film suitable for the countryside in China.

Description

technical field [0001] The invention relates to an agricultural film and a preparation method thereof. This composite film has multiple functions of fertilizer, pesticide and pigment, and is suitable for a series of polyolefin plastic products such as mulch film, flower pots (including plastic flower pots), and transplant pots. The composite method adopts the spraying or smearing process at normal temperature. The process is simple, the operation is convenient, and the investment in equipment is small. It is a good film suitable for the vast rural areas of our country. Background technique [0002] One of the currently used mulch films at home and abroad is a single-layer film, which adopts a high-temperature blow molding method. 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 mulch is limited, the process is co...
