Problems solved by technology

In the production process of existing plastic bottles, polyethylene or polypropylene and other materials are mixed, heated and melted with various organic solvents, and then made by hot pressing molding technology. These two materials, polyethylene or polypropylene, are non-toxic and tasteless , high safety performance to the human body, but polyethylene and polypropylene are refractory organic compounds
After the plastic bottle is used, it is difficult to degrade and easily lead to white pollution, which is not conducive to environmental protection

Abstract

The invention discloses a degradable composite material for plastic bottles and a preparation method thereof. The degradable composite material for the plastic bottles is prepared from the following raw materials in parts by weight: 55-75 parts of polylactic acid, 12-22 parts of ginkgo sawdust, 10-30 parts of gelatin, 6-12 parts of ramie fiber, 5-10 parts of chitosan, 5-15 parts of canna starch, 2-6 parts of glass fiber, 1-6 parts of calcium phosphite, 1-4 parts of magnesium hydroxide, 2-6 parts of nano-silica, and 2-5 parts of gluconic acid. The degradable composite material for the plastic bottles disclosed by the invention has good degradation performance, and can be relatively well used for preparing plastic bottles; moreover, white pollution can be avoided so as to be more environmentally friendly. In addition, the raw materials are easy to obtain, and the preparation processes are simple and easy to implement; and thus, promotion is facilitated.

Description

Technical field [0001] The invention relates to the technical field of plastic bottles, in particular to a composite material for degradable plastic bottles and a preparation method thereof. Background technique [0002] Plastic bottles are widely used in people's daily life and work, providing convenience to people's life and work, and are welcomed by people. In the production process of the existing plastic bottles, they are mainly made by mixing materials such as polyethylene or polypropylene with a variety of organic solvents, heating and melting, and then making them through thermoforming technology. The two materials of polyethylene or polypropylene are non-toxic and tasteless. , High safety to human body, but polyethylene and polypropylene belong to refractory organic matter. After plastic bottles are used, they are difficult to degrade and easily cause white pollution, which is not conducive to environmental protection. Therefore, the present invention provides a compos...
