Agricultural liquid mulching film and production method thereof
An agricultural mulch, liquid technology, applied in chemical instruments and methods, applications, agriculture, etc., can solve the problem of crop areas that cannot adapt to high precipitation, the tensile strength and water resistance of liquid mulch are not strong, and the viscosity of biodegradable liquid mulch is formed. Low problems, to achieve the effect of enhancing viscosity, non-toxic side effects, and improving strength

[0016] Example 1
[0017] Before the liquid agricultural film is produced, the following raw materials are selected according to the weight ratio: 50 parts of sweet potato starch, 30 parts of industrial alcohol, 25 parts of white sugar, 20 parts of chitin, 15 parts of polyacrylamide, 15 parts of fatty acid sodium , 12 parts of polyurethane water-based resin, 10 parts of green agent, 5 parts of barium stearate, 5 parts of water-retaining agent, 2 parts of crosslinking agent SAC-100, 3 parts of magnesium aluminum hydrotalcite, 1 part of Surfactant, 6 parts of soil conditioner and 1500 parts of water.
[0018] The liquid agricultural film production method: ① Take 400 parts of water solution into a stainless steel reaction tank, then add 50 parts of sweet potato starch and 25 parts of white sugar, use a steam boiler to heat, stir while heating, stir and gelatinize at 70℃. Minutes, it becomes a transparent sticky starch paste;
[0019] ②Then add 30 parts of industrial alcohol solution,...
