A kind of polypropylene agricultural biological non-woven fabric and preparation method thereof

Abstract

The invention discloses polypropylene agricultural biological non-woven fabric and a preparation method thereof. The polypropylene agricultural biological non-woven fabric is made from 71.90-78.15% of polypropylene, 2.15-3.95% of insect repellent, 1.30-2.15% of degrading agent, 14.25-15.35% of plant fiber, 0-1.35% of anti-oxidant , 0-1.95% of coupling agent and 0-3.65% of processing aid by weight through a melt blowing method. The preparation method includes using polypropylene as raw material, adding insect-resistant mosquito-repellent master batch, performing spray fusing, cleaning, melting, filtering and forming a net and so on to obtain the polypropylene agricultural biological non-woven fabric. The polypropylene agricultural biological non-woven fabric produced by the process technology is low in use cost, has good insect resisting and degrading functions, is capable of reducing the insect attack and the damage to the environment and has advantages of broad application range, great market potential and good economical benefit.

Description

Technical field [0001] The invention relates to the field of agricultural non-woven fabrics, in particular to a polypropylene agricultural biological non-woven fabric and a preparation method thereof. Background technique [0002] Plastic agricultural mulch film has the effect of conserving moisture and warming the soil, and consequently it has brought about a bumper harvest for agriculture. It has been hailed as the third revolution in agriculture after the collection of fertilizers and seeds. my country is currently also the country with the largest amount of agricultural mulch film production and use in the world, 1.6 times the total amount used in all other countries. [0003] The good temperature and moisture preservation effect of agricultural mulch has had a significant and positive effect on China’s agriculture, but at the same time, with the popularization of mulching technology, residual agricultural mulch has also brought a series of negative effects, a large number of r...

AI Technical Summary

Problems solved by technology

[0003] The good temperature-increasing and moisture-retaining effect of agricultural mulch film has had a significant and positive effect on China's agriculture, but at the same time, with the popularization of mulching technology, the residual agricultural mulch film has also brought a series of negative effects. A large number of residual mulch film damage Soil structure, endangering the normal growth and development of crops and causing crop yield reduction, which in turn affects the agricultural environment
