Embodiment

[0015] The specific preparation process of the new environmental protection mulch film mentioned in the present invention is as follows:

[0016] a) To prepare thermoplastic starch, the main components and percentages of thermoplastic starch are: ultra-fine starch 75%, glycerin 12.5%, stearic acid 10%, liquid paraffin 2.5%; the preparation process is as follows: first, add 75% % Super-fine starch, 4% glycerin, 3.5% stearic acid and 1% liquid paraffin are added to the kneader, the kneader is heated to 80°C, and stirred at high speed for 5 minutes; then, at 5 minute intervals, Add the remaining 8.5% glycerin, 6.5% stearic acid and 1.5% liquid paraffin to the kneader in two times, stir at high speed for 10 minutes, and control the temperature of the kneader at 85℃-90℃; finally, cool in the kneader, Prepared thermoplastic starch; because ordinary starch molecules contain a large number of hydroxyl groups, the effect of intermolecular hydrogen bonds makes the glass transition temperat...

Abstract

The invention discloses a novel environment-friendly mulching film. The mulching film mainly comprises the components in percentage as follows: 55%-65% of low density polyethylene, 25%-35% of degradable master batch and the balance of related assistants. The mulching film is prepared with a blow molding technology. The novel environment-friendly mulching film is reasonable in component preparation and stable in usability, has good degradability as well as water retention and thermal insulation properties, and can meet requirements of the modern agricultural production.

Description

Technical field [0001] The invention relates to a mulch, in particular to a new type of environmental protection mulch, and belongs to the technical field of plastic products. Background technique [0002] With the advancement of science and technology and the development of the plastic industry, various plastic products are widely used in social production and living areas. Among them, mulch is one of the most widely used plastic products in agricultural production. According to statistics, the national mulch consumption in 2013 was 1.2 million tons , Covering 350 million mu of cultivated area. The use of mulch has made important contributions to our country's agriculture, but also brought serious white pollution. At present, the average residual amount of mulching film per mu is 5-15 kg per mu of farmland soil covered with plastic film. [0003] In the current technology, there are two main ways to solve the residual mulch film: recycling and degradation. The recycling method ...
