Antibacterial and mildew-proof reinforced polypropylene composite material for fan blades and preparation method thereof

Abstract

The invention relates to an antibacterial and mildew-proof reinforced polypropylene composite material for fan blades and a preparation method thereof; the polypropylene composite material comprises PP, a reinforcing agent, a first compatilizer, an auxiliary agent, an inorganic antibacterial agent, an organic mildew preventive and electret masterbatch; the inorganic antibacterial agent takes silver, copper and zinc as antibacterial main bodies, and takes permutite, silicon, apatite, titanium oxide and zirconium phosphate as antibacterial carriers; the organic mildew preventive is one or a compound of two or more of tetrachloroisophthalonitrile, diclofenac, phenol, pentachlorophenol, phenyl mercury oleate, 8-hydroxyquinoline copper, mercuric chloride and sodium fluoride; the electret masterbatch comprises the main components: 0-100 parts of polypropylene, 8-50 parts of an electret agent, 0-3 parts of a second compatilizer, 0.05-0.35 part of a first antioxidant and 0-3 parts of an anti-aging agent. According to the invention, a compound system of the inorganic antibacterial agent and the organic mildew preventive is adopted, so that the material plays a synergistic mildew-proof rolein the organic mildew preventive and the antibacterial agent.

Description

technical field [0001] The invention relates to a composite material, in particular to an antibacterial and mildew-proof reinforced polypropylene composite material for wind blades and a preparation method thereof. Background technique [0002] With the continuous improvement of living standards, people pay more and more attention to physical health, so the requirements for household appliances are getting higher and higher, especially for air conditioners, air purifiers and other electrical appliances, which must have antibacterial and deodorizing functions. Air conditioners, air purifiers and other fans will accumulate a large amount of dust, bacteria, mites and other harmful substances during long-term operation. Over time, mold and odor will grow, unknowingly endangering people's health. Therefore, major electrical companies require that the fan blade material must have functions such as antibacterial, mildew resistance, and dust adsorption. [0003] Polypropylene (PP f...

AI Technical Summary

Problems solved by technology

However, the strength of polypropylene resin is low, and it is easy to deform when directly used for injection molding fan blades, which affects the air volume, so it needs to be reinforced and modified
