Antibiotic air filter paper and preparation method thereof
ActiveCN101349031ASimple structureEfficient bactericidalPaper/cardboardSynthetic cellulose/non-cellulose material pulp/paperGlass fiberAir filter
The invention provides air filter paper which is effective in anti-bacterial performance and has a simple structure and a preparation method thereof. The anti-bacterial air filter paper comprises a filter paper substrate and an antibacterial agent covered on the surface of the filter paper substrate, and the mass of the antibacterial agent is 0.05 to 1 percent against that of the filter paper substrate. The filter paper substrate is preferably glass microfiber air filter paper, in particular air filter paper produced by glass microfibers, non-alkali continuous glass fiber chopped strands and organic fibers or plant fibers. The antibacterial agent is preferably a nano-silver ion antibacterial agent. As the improvement of the invention, adhesive can be used for the adhesion of the antibacterial agent and the filter paper substrate. The preparation method for the air filter paper has the following steps that: the surface of the filter paper substrate is sprayed with a diluent of the antibacterial agent and then is dried. The adhesive can also be sprayed after the diluent of the antibacterial agent is sprayed. The air filter paper has a simple structure, simple and convenient process, low cost, and high-efficiency sterilization and bacteria-inhibiting performances due to the fact that the antibacterial agent covers the surface of the air filter paper and partially permeates the air filter paper.
