[0002] Xinjiang is the largest agricultural film-covered planting area in China and even in the world. It consumes about 300,000 tons of agricultural ground-covering film (referred to as: plastic film) every year. farmland white pollution
The cumulative amount of residual plastic film in the farmland reaches 30-60kg, and the seeds cannot take root and rot, which seriously affects the growth of the root system of the crops, resulting in a reduction in crop production

Abstract
The invention relates to a formula of agricultural plastic mulching films and in particular relates to an agricultural plastic polyethylene mulching film. The agricultural plastic polyethylene mulching film comprises the following raw materials in parts by weight: 86-90 parts of linear polyethylene, 10-14 parts of metallocene polyethylene, 2-3 parts of an anti-ageing master batch special for Demelon mulching films and 0.5-3 parts of an opening master batch special for Demelon mulching films, wherein the anti-ageing master batch special for Demelon mulching films comprises the following components: 86-90 parts of polyethylene, 14-20 parts of a light stabilizer 944, 3-5 parts of an antioxidant 1010, 0.5-1 part of zinc oxide and 0.5-1 part of zinc stearate; and the opening master batch special for Demelon mulching films comprises the following components: 80-90 parts of calcium carbonate/silica having the granularity of 20000 meshes, 10-15 parts of wax and 7-10 parts of polyethylene. According to the agricultural plastic polyethylene mulching film disclosed by the invention, the production cost increased because the thickness of the mulching film is increased by 20% during agricultural production can be reduced, the acceptance criteria enthusiasm of peasant households is improved, and the efficiency of DB 65 3189-2014 enforced standard implementation is improved.
Description
technical field [0001] The invention relates to a formula of agricultural mulching film, in particular to a polyethylene agricultural mulching film. Background technique [0002] Xinjiang is the largest agricultural film-covered planting area in China and even in the world. It consumes about 300,000 tons of agricultural ground-covering film (referred to as: plastic film) every year. Farmland white pollution. The cumulative amount of remaining mulch film in the farmland reaches 30-60kg, and the seeds cannot take root and rot, which seriously affects the growth of the root system of the crops and reduces the yield of the crops. [0003] In order to control the white pollution of farmland, the Xinjiang Uygur Autonomous Region issued the DB65 3189-2014 "Polyethylene blown agricultural ground cover film" local mandatory standard on December 1, 2014. The Standing Committee of the Twelfth People's Congress of the Xinjiang Uygur Autonomous Region A meeting reviewed and passed the ...
