Abstract

The invention discloses antibacterial coating for the surface layer of medical equipment and a preparation method of the antibacterial coating. The antibacterial coating comprises, by weight, 28-35 parts of epoxy resin, 20-30 parts of organic siloxane resin, 8-16 parts of ash-calcium powder, 6-12 parts of calcium silicon, 4-8 parts of talcum powder, 3-6 parts of mica powder, 4-7 parts of castor oil, 3-8 parts of chitosan, 5-10 parts of zeolite powder, 3-6 parts of zirconium phosphate, 2.5-4.3 parts of nano silver, 3-5 parts of nano titanium dioxide, 4-7 parts of nano zinc oxide, 3-6 parts of activated carbon, 2-5 parts of bamboo carbon powder, 2.3-3.8 parts of polyhexamethylene biguanidine hydrochloride, 3.5-5.2 parts of titanate coupling agent, 1.5-2.6 parts of dispersing agent, 2.4-3.6 parts of preservatives, 1.8-3.4 parts of leveling agent, 0.8-2.2 parts of defoaming agent and 15-23 parts of water. The antibacterial coating is good in adhesiveness, less prone to falling and excellent in antibacterial effect.

Description

technical field [0001] The invention relates to the field of antibacterial coatings, in particular to an antibacterial coating for the surface layer of a medical device and a preparation method thereof. Background technique [0002] Medical devices refer to instruments, equipment, utensils, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are directly or indirectly used on the human body. The effect is mainly obtained through physical methods, not through pharmacological, immunological or metabolic methods, or although these methods are involved, they only play an auxiliary role. The purpose is diagnosis, prevention, monitoring, treatment or mitigation of disease; diagnosis, monitoring, treatment, mitigation or functional compensation of injury; examination, replacement, regulation or support of physiological structures or physiological processes; life support or maintenance; pregnancy control; To provide information for medic...
