Abstract

The invention discloses a durable flame-retardant, antibacterial and waterproof finishing agent, a preparation method thereof and application thereof. The durable flame-retardant, antibacterial and waterproof finishing agent comprises composition A and composition B. Preparation materials of the composition A comprises, by weight, 18-50 parts of cyclic phosphoric ester flame-retardant agent, 6.0-18 parts of fluorine-based waterproof agent, 0.6-6.0 parts of flame-retardant cross-linking agent, 0.1-1.0 part of amino acid, 9-30 parts of deionized water, and 0.05-0.3 part of nonionic surfactant. The composition B comprises, by weight, 0.03-0.2 part of silver-based antibacterial agent, 0.3-2.0 parts of organic antibacterial agent, 0.01-0.2 part of wetting dispersant, 1.0-6.0 parts of phosphorus-nitrogen-containing flame-retardant agent, and 2.5-9.0 parts of deionized water. After being applied to polyester textiles, the durable flame-retardant, antibacterial and waterproof finishing agent of the invention can provide the polyester textiles with good flame retardancy, antibacterial property, water resistance, good human-body-friendly property, environmental protection and durability. Thedurable flame-retardant, antibacterial and waterproof finishing agent has good application prospects in hospitals, cinemas, theaters, vehicles, ships, airplanes, inns, hotels, schools, nursing homes,cosmetic medicine centers, rehabilitation centers, disease prevention and control centers and other places.

Description

technical field [0001] The invention relates to the technical field of functional finishing agents, in particular to a durable flame-retardant antibacterial and waterproof finishing agent and its preparation method and application Background technique [0002] In recent years, with the rapid increase in the consumption of decorative textiles, fires caused by textiles have continued to increase. Improving the flame retardant function of textiles has become one of the focuses of the industry. GB / T17591-2006 "Flame Retardant Fabrics", GB20286-2006 "Requirements and Labeling of Flame Retardant Products and Components in Public Places" and GB8624-2012 "Classification of Combustion Behavior of Building Materials and Products" all put forward strict requirements on the flame retardant of textiles. The flame retardant requirements, especially GB20286-2006, GB8624-2012, have higher requirements on oxygen index index and vertical combustion performance. [0003] On the other hand, t...
