Problems solved by technology

Most of the existing plastic bags used for loading are synthesized by non-degradable raw materials, and a large amount of discarded plastics account for 40% of the garbage. People call this kind of pollution "white pollution". While it brings convenience to people's lives, it also brings unmanageable troubles to the homes that people depend on for survival.
[0003] The use of degradable natural fibers as the main raw material to prepare degradable plastic bags for packaging has become a research hotspot around the world. The existing degradable plastic bags for packaging generally have the following problems: the mechanical properties of the selected natural fiber raw materials The poor physical and mechanical properties of the prepared plastic bags lead to a decrease in the mechanical properties; the low mechanical properties eventually lead to poor load-bearing properties of the plastic bags, which cannot be used and carried repeatedly, and have a short service life; the color is dull and yellowish, and the transparency is low, which affects the appearance. Not widely promoted in the market; poor water resistance, poor environmental resistance and antibacterial performance; complex preparation methods and high cost
The above defects have seriously hindered the wide application of degradable plastic bags in life

Abstract

The invention discloses an environment-friendly and durable sisal bag and a preparation method thereof. The environment-friendly and durable sisal bag comprises raw materials in parts by weight as follows: sisal fibers, shengma fibers, ramie fibers, bamboo fibers, carbon fibers, banana fibers, konjac starch, polyvinyl alcohol, polyvinyl chloride, aromatic particles, negative ion mineral particles, thermoplastic polyurethane, titanium dioxide, laccase, agar, a plasticizer, a surfactant, a plant extract solution and an antibacterial agent. The natural degradable fibers including the sisal fibers, the shengma fibers, the ramie fibers, the bamboo fibers, the carbon fibers and the banana fibers are selected as the main raw materials, the plastic bag can be degraded rapidly in a natural state by means of combined use of titanium dioxide and the laccase, and by means of cooperation with other additives such as the plasticizer, the surfactant and the like, the environment-friendly and durable sisal bag is easy to degrade and has higher environmental resistance, water resistance, durability and antibacterial property.

Description

technical field [0001] The invention relates to a daily necessities. More specifically, the present invention relates to a sisal environment-friendly durable bag and a preparation method thereof. Background technique [0002] Storage bags are indispensable items in people's daily life, especially plastic bags, which are widely used because of their cheapness, light weight, large capacity, and easy storage. Most of the existing plastic bags used for loading are synthesized by non-degradable raw materials, and a large amount of discarded plastics account for 40% of the garbage. People call this kind of pollution "white pollution". While it brings convenience to people's lives, it also brings unmanageable troubles to the homes that people depend on for survival. [0003] The use of degradable natural fibers as the main raw material to prepare degradable plastic bags for packaging has become a research hotspot around the world. The existing degradable plastic bags for packagin...
