Abstract

The invention discloses a special composite antibacterial agent for a children bicycle. The special composite antibacterial agent comprises the following components by weight: 0.007-0.014 part of 1-bromo-3-chloro-5,5-dimethyl hydantoin, 100-200 parts of an inorganic antibacterial agent, 100-150 parts of dodecyl-dimethyl-benzyl ammonium chloride, 100-200 parts of microcrystal kaolinite powder, 50-80 parts of a fluoroalkyl silane coupling agent, 30-50 parts of 2,6-di-tert-butyl-4-methylphenol, and 10-20 parts of sulpho-bi-acrylate; the invention further provides a composite antibacterial coatingprepared from the composite antibacterial agent and a preparation method of the composite antibacterial agent. The body of the children bicycle has excellent antibacterial, bacteriostatic and sterilizing properties while the effects of attractiveness, decoration and rust resistance are achieved, various bacteria adhered to the surface of the body are effectively killed, the cross propagation of the bacteria is completely eradicated for the children in the process of touching and playing with the bicycle, the bacterial infection is avoided, and the body health of the children is guaranteed.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a special composite antibacterial coating for children's bicycles, a composite antibacterial agent and a preparation method of the composite antibacterial agent. Background technique [0002] Children's bicycles are toys and means of transportation that children like very much. They are very popular. Almost every child has a children's bicycle in his childhood. Riding a children's bicycle brings endless fun to children. Regular riding of children's bicycles can exercise children's responsiveness and balance ability, and promote their physical and mental health and growth. [0003] Various bacteria widely exist in nature, distributed in the air, water, soil and the surface of various objects. Many bacteria are pathogenic, and the surface of children's bicycles is no exception. Various bacteria are also attached and parasitic. In warm and humid climate areas or hot and humid seas...
