Abstract

The invention discloses an agricultural film material and a preparation technology thereof. The agricultural film material comprises the following components in parts by weight: 20-40 parts of high density polyethylene, 10-20 parts of cellulose, 8-20 parts of flexibilizer, 4-12 parts of ethylene-vinyl acetate copolymer, 5-15 parts of acetyl citrate, 3-9 parts of epoxidized soybean oil, 4-12 partsof di(2-ethylhexyl)-4,5-epoxytetrahydrophthalate, 6-20 parts of corn starch and 1-4 parts of graphene oxide. According to the invention, the preparation technology is simple, the prepared film material is capable of promoting the degrading property of the film and the residual film and fragments in the soil are reduced.

Description

technical field [0001] The invention relates to the technical field of film material preparation, in particular to an agricultural film material and a preparation process thereof. 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. 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. Contents of the invention [0003] The object of the present invention is to provide an agricultural film material and its preparation process, so as to solve the problems rai...
