Abstract

The invention discloses a plastic mulching film, belonging to the technical field of agricultural materials. The plastic mulching film comprises the following raw materials in parts by weight: 50-60 parts of linear low density polyethylene, 40-50 parts of 120-mesh potato starch, 10-20 parts of polypropylene, 1-5 parts of polyvinyl alcohol, 0.5-1 part of tert-butyl cumine hydroperoxide, 0.5-1 part of nano-level titanium dioxide, 5-8 parts of microcrystalline wax, 0.5-1 part of iron stearate and 8-10 parts of calcium carbonate, and is prepared by the process steps of stirring, heating, extrusion, blow molding, film formation, cutting and the like. The plastic mulching film disclosed by the invention can be completely degraded, cannot cause pollution to the environment, does not have residues left, and is an environment-friendly plastic mulching film.

Description

technical field [0001] The invention belongs to the technical field of agricultural materials, in particular to a plastic mulch. Background technique [0002] my country is a large agricultural country with a large population. Agricultural issues are important strategic issues related to the national economy and people's livelihood. Plastic film has a good effect of increasing temperature and moisturizing, and can greatly increase the yield of crops. It is one of the important materials for agricultural production after seeds, chemical fertilizers and pesticides. The application of plastic film technology has greatly promoted the improvement of agricultural production and benefits. It has led to the change of agricultural production mode and the rapid development of agricultural productivity. [0003] However, the traditional plastic mulch has a big disadvantage - it is difficult to degrade. Due to this shortcoming, the traditional plastic mulch has brought serious harm to...
