Abstract

The invention discloses a flame-retardant antibacterial transparent polypropylene material and a preparation method thereof. The polypropylene material is prepared from the following components in percentage by weight: 79.1-91.2% of polypropylene, 3.0-5.0% of linear low-density polyethylene, 2.0-5.0% of toughening agent, 0.1-0.3% of white oil, 1.0-4.0% of flame retardant, 0.1-0.4% of nucleating agent, 2.0-5.0% of antibacterial agent, 0.4-0.8% of lubricant and 0.2-0.4% of antioxidant. The flame-retardant antibacterial transparent polypropylene material disclosed by the invention has the advantages that the flame retardant and antibacterial agent in the formula are compounded, thus the prepared polypropylene material has the flame retardant and antibacterial effects at the same time; and the product has low smoke density during combustion, is difficult to change color and has low cost.

Description

[technical field] [0001] The invention relates to the field of polymer materials, in particular to a flame-retardant and antibacterial transparent polypropylene material and a preparation method thereof. [Background technique] [0002] Polypropylene has the characteristics of low production cost, good comprehensive mechanical properties, non-toxic, light weight, corrosion resistance, easy processing and recycling, etc., so it has been widely used, but it is a flammable material, so it is very important to give it flame retardant properties. important and necessary. [0003] In daily life, people will inevitably come into contact with bacteria. As people's health awareness increases, antibacterial plastics will also be used more and more. Antibacterial agents that play an antibacterial role in antibacterial plastics can be mainly divided into organic antibacterial agents and inorganic antibacterial agents. At present, the commonly used inorganic antibacterial agents have pro...
