Halogen-free flame-retardant high-heat-resistance antibacterial polypropylene composite material and preparation method thereof

Abstract

The invention discloses a halogen-free flame-retardant high-heat-resistance antibacterial polypropylene composite material and a preparation method thereof. The halogen-free flame-retardant high-heat-resistance antibacterial polypropylene composite material comprises the following raw materials in parts by weight: 54-96 parts of polypropylene, 0-20 parts of talcum powder, 0-7 parts of elastomer, 0-5 parts of composite antibacterial agent, 0-10 parts of halogen-free flame retardant, 0-2 parts of coupling agent, 0.1-2 parts of antioxidant and 0-2 parts of other aids. The novel organic-inorganic composite antibacterial agent is added on the basis of the formula of the polypropylene composite material; and the combination of the guanidine salt polymer and titanium dioxide can well perform the synergistic functions to enhance the antibacterial property and heat resistance of the polypropylene composite material. The novel silicon halogen-free flame retardant phosphorus silsesquioxane is also introduced into the polypropylene composite material system; and the added novel silicon halogen-free flame retardant phosphorus silsesquioxane has the advantages of low consumption and high flame-retardant efficiency, and can effectively enhance the flame retardancy of the composite material system.

Description

technical field [0001] The invention belongs to the technical field of polymer modification and processing, and relates to a halogen-free flame-retardant high-heat-resistant and antibacterial polypropylene composite material and a preparation method thereof. Background technique [0002] Polypropylene, as one of the five general-purpose plastics, is widely used in construction, transportation, automobiles, home appliances and other fields because of its non-toxic, light weight, low price, chemical corrosion resistance, and good physical processing properties. It is also the current growth rate A general-purpose plastic with the fastest consumption and large amount. However, polypropylene also has disadvantages such as low mechanical strength, poor low-temperature impact, poor heat resistance, and easy aging. Usually, it needs to be modified by modifying polypropylene itself or adding additives to improve performance to meet people's daily needs. The growing and diversified ...

AI Technical Summary

Problems solved by technology

[0004] As a kind of plastic, polypropylene is obviously extremely flammable, and its products have certain unsafe factors in daily use. Generally, it is necessary to add flame retardants to improve the flame retardancy of polypropylene materials to make polypropylene materials suitable for use in electronic equipment. , household appliances, automobiles and other application fields are not restricted; traditional halogen-containing flame retardants release some carcinogenic substances when burned, some developed countries and regions have implemented a ban on some halogen-containing flame retardants
