Abstract

A high-efficiency and environmental-protection agricultural mulching film is prepared from the following raw materials in parts by weight: 35-55 parts of polyethylene, 1.2-1.5 parts of an ultraviolet light absorber, 20-27 parts of a PBM biodegradable material, 1.2-2.4 parts of a fog-reduction agent, 12-16 parts of thermoplastic starch, 1-3 parts of polyvinyl chloride, 3-4 parts of polymethyl ethylene carbonate, 2-5 parts of nanoscale titanium dioxide, 3-6 parts of polyvinyl alcohol, 4-7 parts of pullulan, 20-26 parts of a PBM biodegradable material, 4-6 parts of p-methyl xylene, 10-13 parts of an environmental-protection catalyst, 22-32 parts of kaolin, and 8-13 parts of a solvation agent. The high-efficiency and environmental-protection agricultural mulching film has the beneficial effects that the high-efficiency and environmental-protection agricultural mulching film has the advantages of simple preparation process, good toughness, high strength, and good environmental protection, and cannot cause damage to soil.

Description

technical field [0001] The invention relates to an efficient and environment-friendly agricultural mulching film. Background technique [0002] As environmental problems increasingly trouble people's lives, people are paying more and more attention to environmental protection, especially like mulch, which looks like a thin layer, but it has a considerable effect. For those seedlings just unearthed, it has the functions of mulching roots and promoting growth. Mulch film can not only improve ground temperature, water retention, soil conservation, fertilizer conservation and fertilizer efficiency, but also kill weeds, prevent diseases and insect pests, prevent drought and waterlogging, suppress salt and preserve seedlings, and improve light and heat conditions near the ground. However, with the continuous development of agricultural modernization, the use of plastic film in rural areas has become an important means to ensure high and stable agricultural production. However, w...
