Abstract

The invention discloses an antibacterial and anti-aging agricultural mulching film. The antibacterial and anti-aging agricultural mulching film comprises, by weight, 30-40 parts of polylactic acid, 14-18 parts of plant starch, 6-10 parts of nitrile rubber, 7-13 parts of polytetrafluoroethylene ultrafine micro-powder, 2-5 parts of sterilization essential oil, 7-12 parts of acetylation chitin whiskers, 4-7 parts of nonionic surfactants, 3-5 parts of cross-linking agents, 2-5 parts of acrylonitrile-butadiene-styrene copolymers, 2-6 parts of silk fibers, 2-4 parts of expanded bentonite, 5-9 partsof ultrafine talc powder, 2-6 parts of sepiolite fibers, 2-4 parts of impact-resistant modifiers, 1-2 parts of stabilizers, 2-5 parts of antioxidants, 1-3 parts of anti-aging agents, 3-6 parts of plasticizers and 2-4 parts of toughening agents. The antibacterial and anti-aging agricultural mulching film has the advantages of corrosion resistance, aging resistance, antibacterial property, abrasionresistance, heat resistance, gas permeability and water permeability. Besides, moisture and the temperatures can be effectively kept by the antibacterial and anti-aging agricultural mulching film, partial germs in soil can be killed by the antibacterial and anti-aging agricultural mulching film, and the antibacterial and anti-aging agricultural mulching film is low in cost.

Description

technical field [0001] The invention relates to the field of plastics, in particular to an antibacterial and antiaging agricultural mulch film. Background technique [0002] my country's film-covered agricultural production began in the 1980s, and then its application area and scope expanded rapidly. At present, it has become one of the countries with the largest film-covered planting area and the largest variety of crops in the world. [0003] Mulch is the ground cover film, usually transparent or black PE film, also green and silver film, used for ground cover to increase soil temperature, maintain soil moisture, maintain soil structure, prevent pests from attacking crops and diseases caused by certain microorganisms, etc. , the function of promoting plant growth. At present, in agriculture, there are two kinds of mulch films commonly used, one is black mulch, and the other is white mulch. Black mulch film has a good moisturizing effect, but it makes the temperature of t...
