Nano antibacterial plastic and preparation method thereof

Abstract

The invention provides a nano antibacterial plastic and a preparation method thereof. The formula comprises the following raw materials in parts by weight: 150 to 180 parts of low-density polyethylene, 40 to 80 parts of dioctyl phthalate, 20 to 40 parts of nano zinc oxide powder, 15 to 36 parts of silver ammonia solution, 21 to 25 parts of nano titanium dioxide, 10 to 15 parts of zinc stearate, 2to 8 parts of oleamide, 1 to 4 parts of antioxidant, 8 to 10 parts of eucalyptus leaf oil and 3 to 5 parts of sansevieria trifasciata oil. The nano antibacterial plastic prepared by the invention hasthe advantages of scientific proportioning of the raw materials, high temperature resistance, bending resistance and high tensile strength, good mechanical properties and excellent antibacterial properties due to addition of the antibacterial agent in an optimal proportion, and can meet the standard requirements of sanitary water pipes when being applied to drinking water pipelines.

Description

technical field [0001] The invention relates to the technical field of polymers, in particular to a nano antibacterial plastic and a preparation method thereof. Background technique [0002] Plastic is a necessity in daily life and brings a lot of convenience to people's life. In recent years, the application of antibacterial polymer materials has become an indispensable and important part of human beings to maintain a healthy life, especially antibacterial plastics, and the current antibacterial plastics The traditional method is used to add organic antibacterial agents and inorganic antibacterial agents, but organic antibacterial agents have short service life and are prone to bacterial resistance, while inorganic antibacterial agents have poor mold performance, slow sterilization speed, and easy discoloration. The combination of antibacterial agents and organic antibacterial agents, and the addition of inorganic particles in inorganic antibacterial agents will affect the ...

[0002] Plastic is a necessity in daily life and brings a lot of convenience to people's life. In recent years, the application of antibacterial polymer materials has become an indispensable and important part of human beings to maintain a healthy life, especially antibacterial plastics, and the current antibacterial plastics The traditional method is used to add organic antibacterial agents and inorganic antibacterial agents, but organic antibacterial agents have short service life and are prone to bacterial resistance, while inorganic antibacterial agents have poor mold performance, slow sterilization speed, and easy discoloration. The combination of antibacterial agents and organic antibacterial agents, and the addition of inorganic particles in inorganic antibacterial agents will affect the physical and mechanical properties of polymer materials, resulting in plastics that have certain antibacterial properties but poor mechanical properties.
