Naturally degradable polymeric material and preparation method thereof

Abstract

The invention discloses a naturally degradable polymeric material and a preparation method thereof. The material is prepared from the following dry materials in parts by weight: 15-50% of starch, 1.5-5% of stearic acid, 5-15% of pine needle meal, 30-60% of plant fiber and / or waste paper scraps and 10-30% of fiber powder, wherein a mixing ratio of the dry materials to hot water is 1: (1.6-2.5). Plant environment-friendly raw materials and degradable materials are adopted and subjected to physical polymerization and gelatinization reactions at high temperature to prepare the naturally degradablepolymeric material; and the produced material is friendly to environment, low in cost and good in structural force and meets the use requirements of the packaging industry.

Description

technical field [0001] The invention relates to the technical field of packaging, in particular to a naturally degradable polymer material and a preparation method thereof. Background technique [0002] At present, paper or plastic materials are mainly used in the packaging field. However, the existing plastic materials are difficult to degrade and cause pollution to the environment. [0003] The existing paper packaging production process, first, needs to cut the paper according to the specifications of the paper packaging, the workload is heavy, and the width of the cut paper is affected by the equipment and the operation skills of the personnel, and the quality of the cutting cannot be guaranteed; second, Paper needs to be glued, and the amount of glue applied is also affected by equipment and personnel operating skills, so its quality cannot be guaranteed; thirdly, glue is used to bond the paper layer by layer, and then use the mold to roll and form. A large amount of ...

However, the existing plastic materials are difficult to degrade and cause pollution to the environment

[0003] The existing paper packaging production process, first, needs to cut the paper according to the specifications of the paper packaging, the workload is heavy, and the width of the cut paper is affected by the equipment and the operation skills of the personnel, and the quality of the cutting cannot be guaranteed; second, Paper needs to be glued, and the amount of glue applied is also affected by equipment and personnel operating skills, so its quality cannot be guaranteed; thirdly, glue is used to bond the paper layer by layer, and then use the mold to roll and form. A large amount of paper and glue are used in the production process. The production cost is greatly affected by papermaking, and the cost of papermaking is also very high, and the pollution caused by papermaking to the environment is also very large. Glue cannot be degraded in nature. High cost; Fourth, the forming part is adjusted by multiple sets of rollers, which requires professional personnel to complete. It is also affected by equipment and personnel operating skills. The entire production process is greatly affected by external factors. If you want to ensure its long-term stability Production, the cost paid is very high, the time spent and the resources used are many
