Problems solved by technology

However, the increase in the use of agricultural film and its refractory property will increase the residual film and its fragments in the soil, causing soil compaction and poor permeability, resulting in a reduction in crop production, and its difficulty in recycling leads to it being discarded in nature. environmental hazards
For crops cultivated in agricultural film greenhouses, if the transmitted sunlight is too strong, it may cause adverse effects such as burns on the crops

Abstract

The invention discloses a water-permeable film for plant protection. The water-permeable film comprises, by weight, 45-65 parts of low-density polyvinyl chloride, 25-35 parts of a PVB polymer, 12-16 parts of carbon black type black polyester masterbatch, 7-9 parts of a light stabilizer, 7-9 parts of permethrin, 3-5 parts of glyceryl monostearate, 3-5 parts of an organic vanadium salt, 3-5 parts ofan antioxidant, 1-3 parts of an anti-aging agent and 1-3 parts of a UV absorber. The invention also discloses a preparation method of the water seepage film for plant protection. The water-permeablefilm can effectively shield the crops so that the crops are prevented from being transmitted by the sunlight too strongly, and the light stabilizer can evenly distribute lights in the water-permeablefilm. The permethrin can treat pests in soil so that the growth of crops is not influenced and the normal growth of plants is guaranteed.

Description

technical field [0001] The invention relates to the technical field of preparation of water-permeable membranes, in particular to a water-permeable membrane for plant protection and a preparation process. Background technique [0002] The main component of agricultural permeable membrane 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. However, the increase in the use of agricultural film and its refractory property will increase the residual film and its fragments in the soil, causing soil compaction and poor permeability, resulting in a reduction in crop production, and its difficulty in recycling leads to it being discarded in nature. The environmental hazards are great. For crops cultivated in agricultural film greenhouses, if the transmitted sunlight is too strong, there may be adverse effects such as burns on ...
