Problems solved by technology

However, polypropylene is a highly flammable material. The limiting oxygen index of polypropylene samples without flame retardants is about 17%. At the same time, polypropylene products are easily contaminated under suitable temperature and humidity conditions during use and storage. and breed a variety of pathogenic bacteria, which threaten the health of users. Therefore, it is of great significance to develop a flame-retardant and antibacterial polypropylene composite material to reduce fires, reduce the incidence of diseases, and protect people's health.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to an antibacterial and flame-retardant polypropylene composite material. Background technique [0002] Compared with other general-purpose thermoplastics, polypropylene has the advantages of low density, excellent mechanical properties, good electrical insulation, small dielectric constant, stress crack resistance, chemical resistance, easy processing, and high heat distortion temperature. It is currently used in household appliances , electronic equipment, vehicles and other fields have a wide range of applications. However, polypropylene is a highly flammable material. The limiting oxygen index of polypropylene samples without flame retardants is about 17%. At the same time, polypropylene products are easily contaminated under suitable temperature and humidity conditions during use and storage. and breed a variety of pathogenic bacteria, which threaten the health of ...
