Abstract

The invention discloses a method for preparing a halamine antibacterial material based on cyanuric chloride. The method comprises the following technological steps of: completely dissolving cyanuric chloride into an alkaline liquor to prepare a finishing liquor, soaking a material to be finished into the finishing liquor until the material is wet, then taking the material out and drying the material after the finishing, solidifying the material at 90-120 DEG C for 10-40 minutes, cleaning the material surface, and finally, halogenating, washing and drying to obtain the antibacterial material. The method is simple in technological operation, low in cost and moderate in reaction condition and has small influence on material mechanical property; and the finished material has excellent antibacterial performance and is safe and toxic-free.

Description

Technical field [0001] The invention belongs to the technical field of antibacterial materials, and specifically relates to a preparation method of cyanuric chloride-based haloamine antibacterial materials. Background technique [0002] There are a large number of disease-causing and mold-causing harmful microorganisms in the human living environment. They can spread through the surface of various materials and products such as fiber, plastic, rubber, paper, and threaten human health. The use of long-lasting antibacterial materials is the simplest, safest and most effective way to effectively prevent the growth, reproduction, spread and spread of harmful microorganisms. The traditional antibacterial agents used for the antibacterial finishing of materials include heavy metals, quaternary ammonium salts, triclosan, etc., but they all have the disadvantages of high price, weak antibacterial ability, low sterilization efficiency, and harmful to the human body. The newly developed h...
