Description

Plastic eating agent production system and production method

Technical Field

The invention relates to the field of plastic degradation, in particular to a plastic eating agent production system and a plastic eating agent production method.

Background

Polyolefin plastics, particularly Polyethylene (PE) and polypropylene (PP), are very widely used in everyday life, such as electronic and electrical packaging, commodity packaging, supermarket shopping bags, takeaway packaging bags, medical packaging, agricultural industry, industrial industry, various plastics, hardware, electrical products, and the like. However, polyolefin plastics are hydrophobic on the surface, inhibit the growth of microorganisms, and in addition, polyolefin itself is structurally very stable, so that it is difficult to degrade in a short time. PE degrades less than 0.5% within 100 years, if exposed to sunlight (UV) for 2 years before biodegradation, the degradation rate can only reach 1%, and the year-by-year accumulation of plastic waste brings great difficulty and challenge to the environment, which is contrary to the concept of sustainable development.

It was found that the degradation of polyolefin plastics involved 2 processes, respectively non-biological oxidative degradation and biological degradation. The non-biological oxidation process is started, mainly photooxidation, thermal oxidation, mechanochemical oxidation and the like, and oxygen in the air reacts with polyolefin under the actions of light, heat, machinery, chemistry and the like. The polyolefin at this stage forms smaller molecular flakes (compared with the original polymer), and functional groups with higher reactivity, such as carboxyl, hydroxyl, ester, aldehyde, alcohol and the like, change from hydrophobicity to hydrophilicity, so that the disintegrated polyolefin absorbs water and provides conditions for the biodegradation at the next stage; this is followed by a microbial degradation process, where microorganisms such as bacteria, fungi, algae use the oxidation products of the polymer chains as carbon sources, thereby forming carbon dioxide, water, biogas, and organic matter.

Research on degradable polyolefin by scientists has been carried out for decades, but commercial application of the degradable polyolefin is not really realized, wherein the biggest problem is low degradation efficiency, and polyolefin materials are difficult to thoroughly decompose into final products such as carbon dioxide, water and the like in a short time; secondly, the contradiction among the service life, the service performance and the degradation performance of the product is difficult to control. Furthermore, control costs are a fundamental problem that commercial applications need to address.

At present, there are some preparation methods of ECO biodegradation plastic gnawing agents, and Chinese invention publication No.: CN111138760a discloses an environment-friendly ECO-biodegradable plastic additive and a preparation method thereof, wherein the additive comprises the following raw materials in parts by weight: 30-50 parts of polypropylene, 20-30 parts of polycaprolactone, 2-5 parts of maleic anhydride grafted polypropylene, 10-15 parts of amine stearate, 5-10 parts of erucamide, 0.5-3 parts of stearic acid, 0.5-3 parts of palmitic acid, 0.5-3 parts of antioxidant and 0.5-3 parts of silane coupling agent. The manufacturing method comprises the following steps: firstly, polypropylene, polycaprolactone, maleic anhydride grafted polypropylene and an antioxidant are mixed and fused for the first time; adding other raw materials, and performing secondary fusion; and injecting or extruding the obtained product into granules to obtain the environment-friendly biodegradable plastic additive. However, the plastic eating agent prepared by the invention adopts a single proportion, and cannot be correspondingly adjusted according to the degradation requirements of plastic products with different functions, the degradation efficiency of the plastic eating agent applied to the plastic products with different functions in different environments is different from the preset degradation efficiency, and the degradation time of the plastic products prepared by the plastic eating agent cannot be adjusted, so that the performance of the degraded plastic products prepared by the plastic eating agent can be possibly influenced.
