Description
Technical field
The present invention relates to antibiotic paint technical field, disclose a kind of Antibacterial Waterborne Emulsion Paint based on Nano-Zinc particle.
Background technology
New demand of antibacterial epoch: in recent years, emerge in an endless stream because of the generation of bacterium transmission of infection hazardous events, the mankind are for the more deep understanding of antibacterial importance, therefore for 3C electronic product, people's livelihood articles for use, underskirt trousers for example, socks, infant's adult diaper, women sanitary articles, as sanitary cotton pad, articles for use between sanitation of bath-room, as sanitising agent, clean hand breast, hand lotion, disinfecting liquid, house protective articles, as mouth mask, air air-conditioning system cleans filter screen, medical treatment product, as bandage, wound patch, synthetic leather, antibiotic and sterilizing salt solution etc., the health requirements of house building materials etc., from raw-material environmental protection, safety, avoid the contact of traditional preservatives to use, further rise to antibacterial requirement.Add that people's life quality promotes and requirement, the product with antibacterial has formed an important link.
At present, traditional emulsion paint is not killed and restraining effect common microorganism, streptococcus aureus (MRSA), streptococcus pneumoniae, Candida albicans, Pseudomonas aeruginosa, black aspergillus etc., use that can not be relieved safely in the time of people's use, and select general antibiotic emulsion paint effectively not better people's living environment.
While utilizing positively charged zine ion to contact with bacterium, because cytolemma/wall of bacterium is pulled open, produce broken hole, make bacterium cannot carry out cytolemma/wall and pulled open and produce broken hole, make bacterium carry out the generation of cytolemma/wall and affect breeding.When zine ion is entered in bacterial body by negative charge sound-absorbing, be combined with the functional group such as inner thiol group (SH), hydroxy, make bacterium because of protein denaturization, cannot normally carry out other reaction of catalysis and affect metabolic function, until bacterium is dead and completely dissolve only.There is the interpolation of high activity, approximately 0.05% Nano-Zinc particle, can cause five kinds of common pathogenic bacterias of human infection, as multiple drug resistance streptococcus aureus (MRSA), streptococcus pneumoniae, Candida albicans, Pseudomonas aeruginosa, black aspergillus etc. produce 99.99% sterilization effect, superbacteria, H1N1, veteran bacterium etc. are also had to manifest function.
