Description

  The present invention relates to a method for producing a multifunctional organic multi-sheet that uses an adhesive liquid and is friendly to the global environment.

  Agricultural multi-sheets that cover the ground bring about changes in agricultural production methods by increasing the temperature of the ground, moisturizing, reducing fertilizer, preventing the growth of weeds, and dramatically improving its productivity. I let you. At present, it is widely used in the production of vegetables such as root vegetables, nurseries, flower buds and fruits. Since the introduction of China in 1978, the use area of multi-seat has been gradually expanded, and in 2005, it already reached 95.9 million tons. The use area reached 13.53 million hm2, and the cultivation area using multi-sheet became the world's largest country. However, since the multi-sheets currently used in China are polyethylene and polyvinyl chloride, the molecular weight is large, the decomposition under natural conditions is difficult, and the thickness of the multi-sheets used in large quantities is 0.012mm. Since the following is the main, the strength is weak and easy to break, wastes labor and time in the recovery process and is difficult to recycle. This causes serious white pollution (due to polystyrene foam containers and plastic bags used for take-out) and consumes a large amount of organic chemical raw materials that cannot be recycled. Therefore, at the same time as inheriting the advantages of multi-sheets, paper-made agricultural multi-sheets made from plant fibers have emerged that have a function that cannot be replaced by multi-sheets.

  However, the existing method for producing paper multi-sheets for paper agriculture is associated with resources that are more or less non-renewable, has qualitative defects and technical complexity, and is currently costly. Therefore, when promoting the application of paper multi-sheets for agriculture, we must first think about the origin of raw materials that are economical, environmentally friendly, recyclable, and capable of reducing costs. It becomes a problem that must not be.

  In view of the drawbacks existing in the known art, the present invention provides a method for producing a multifunctional organic multi-sheet that is friendly to the global environment using a technically mature adhesive liquid. As a result, agricultural multi-sheets are required mechanical strength, light permeability, breathability, heat retention, moisture retention or other special effects (addition of bactericidal disinfectant, supplementation of nutrient elements, fertilizer release control, etc.) Can be provided. The characteristics of the paper agricultural multi-sheet produced in the present invention are its economical and environmentally friendly characteristics, and the raw materials are abundant, inexpensive, biodegradable, soil improvement, time and labor cost. It shall have characteristics such as saving.
