Oxidation-resistant agricultural mulching film

Abstract

The invention relates to an oxidation-resistant agricultural mulching film. The oxidation-resistant agricultural mulching film is prepared from the following raw materials in parts by weight: 8-17 parts of tripolyglycerol monostearate, 4-6 parts of PVC resin, 5-9 parts of acetyl tributyl citrate, 7-11 parts of homo-polypropylene resin, 3-9 parts of polylactic acid, 6-10 parts of polycaprolactone, 5-8 parts of low-density polyethylene, 6-8 parts of polypropylene glycol, 4-7 parts of epoxy resin, 2-6 parts of antioxidant, 1-5 parts of photostabilizer, 3-8 parts of linear low-density polyethylene resin, 4-8 parts of chlorinated polyethylene and 3-5 parts of liquid paraffin. The oxidation-resistant agricultural mulching film has the beneficial effects that the oxidation-resistant agricultural mulching film disclosed by the invention has very good oxidation resistance and meanwhile is high in strength, strong in toughness and low in cost.

Description

technical field [0001] The invention relates to an anti-oxidation agricultural mulch film. Background technique [0002] The main component of agricultural mulch film is polyethylene or polypropylene, which is currently the most produced plastic product in the world. The use of agricultural film is beneficial to the growth and development of crops and increases crop yield. At the same time, agricultural mulch can play a role in heat preservation. Generally, agricultural mulch is used in early spring, when the temperature is low, so the use of mulch can raise the ground temperature earlier, which is conducive to the growth of crops. Secondly, it has a moisturizing effect, can maintain moisture, and has a certain effect of sterilization and insect repellent. However, the existing mulch films generally have weak oxidation and ultraviolet resistance, short service life, and waste of resources. Contents of the invention [0003] In view of the deficiencies of the prior art, ...
