High polymer packaging material being easy to degrade under natural condition and preparation method of high polymer packaging material

Abstract

The invention discloses a high polymer packaging material being easy to degrade under a natural condition and a preparation method of the high polymer packaging material, and belongs to the technicalfield of preparation of new high polymer materials. The high polymer packaging material is prepared from the following raw materials: polyethylene, phosphated distarch phosphate, nano copper oxide mimic enzyme, a microbial nutrition additive, maleic anhydride grafted polyethylene, stearate, hydrotalcite, a methyl vinyl ether-maleic anhydride copolymer, sodium saccharin, mixed polyol, mixed polyatomic acid, a compatilizer, a plasticizer and an antioxidant. Green and low-energy consumption compatibility improvement is carried out on high polymers and nano powder by utilizing a high-energy ball milling mechanical reactor, and the high polymer packaging material being easy to degrade can be prepared through melt extrusion and film blowing. An obtained product is good in performance, low in cost and simple in production technology, can induce multiple factors to achieve a synergistic effect, and can be rapidly degraded in a natural environment.

Description

technical field [0001] The invention relates to a polymer packaging material that is easily degradable under natural conditions and a preparation method thereof, in particular to the technical field of easily degradable green polyethylene packaging materials, and belongs to the technical field of preparation of new polymer materials. Background technique [0002] The annual consumption of plastic products in the world is huge. Due to the stable physical and chemical structure of plastic products, they may not be decomposed in the natural environment for tens to hundreds of years. How to effectively combine the intrinsic life and service life of ordinary plastics, so that non- or non-degradable plastics can obtain degradable properties after use, so that humans can continue to use cheap, light, high specific strength and hygienic plastic products, It is also the key to avoiding white pollution caused by waste plastics. [0003] The existing natural degradable polymer materia...

AI Technical Summary

Problems solved by technology

[0003] The existing natural degradable polymer materials are usually expensive and their strength needs to be strengthened. Obtaining degradable polymer composite materials through modification is an economically feasible technical route. The existing composite polymer materials obtained by blending modification have the following Defects: weak degradability, complex production process, use of a large number of high-cost fully degradable raw materials, such as polylactic acid, polyester, etc., resulting in high production costs and weak market competitiveness

In addition, there are also defects such as the unbalanced degree of degradability and mechanical processing performance, and it is difficult to compete with existing plastic products that have occupied the market for a long time, which is the main obstacle for existing degradable plastics to enter the market
