Abstract

The invention discloses a polyester color master batch having an antibacterial function. The polyester color master batch comprises, by mass, 20-50% of a carrier, 25-40% of an antibacterial agent, 10-25% of a pigment, 0.5-2% of a nucleating agent, 3-5% of a dispersant, 0.5-3% of a coupling agent and 0.1-1% of a stabilizer. The master batch prepared in the invention has an antibacterial function and also has a coloring performance when the master batch is used in polyester, and also has the advantages of lasting antibacterial property, stable performances, strong coloring strength, good dispersity, use convenience, low cost and wide application prospect.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polyester color masterbatch with antibacterial function. Background technique [0002] Polyethylene terephthalate, referred to as polyester (abbreviated as PET in English), is a crystalline polymer. Due to its high strength, large elastic modulus, good heat resistance, and excellent chemical stability, polyester has been widely used in high-rise buildings, commercial buildings, airports, auditoriums, indoor entertainment venues, and transportation fields. . Polyester is another kind of engineering plastic, its creep resistance, fatigue resistance, friction and wear resistance are extremely outstanding, and its comprehensive performance is better than that of polyamide and polycarbonate. With the improvement of people's living standards, the demand for antibacterial polyester is also increasing. Adding an appropriate amount of antibacterial agent can give polyester ...
