Technical Field
The invention relates to a terrace material, in particular to a silver ion antibacterial terrace material and a preparation method thereof.
Background
The terrace material is a part in contact with a soil layer in a building, needs to have good mechanical property and chemical property, is used on the surface of the building, is widely applied to the ground of the building in a production workshop, outdoor sports, schools, hospitals and parking lots, and has the most common terrace materials at present, namely epoxy resin, polyurethane and other terrace materials. With the attention of people on environmental sanitation and health, particularly the requirements of the food industry and the medicine field on environmental sanitation are increasingly high, and meanwhile, the terrace material has good antibacterial property, hardness, wear resistance and other properties, so that the terrace material can effectively solve the problem of complex cleaning of bacteria on the floor in a clean workshop or indoors.
At present, silver ion bactericides are mostly used in the market, and mainly achieve the purpose of sterilization by using silver ions to pierce cell membranes and cell walls of bacterial cells, but because the oxidizability of the silver ions is very strong, the silver ions are rarely used for sterilization alone, and the simple substance silver is a relatively stable element and is not easy to release the silver ions, so that research is carried out on making the simple substance silver into a nano silver form, and the silver ions are released to achieve the purpose of antibiosis. Meanwhile, related researches are carried out to apply nano silver to a floor material, and the nano silver is added into aqueous bisphenol A epoxy resin and aqueous polyurethane to prepare the epoxy floor coating in a patent CN201910183944.X, but the nano silver is easy to agglomerate in a system, so that the antibacterial performance of the epoxy floor coating is not evaluated in the patent. Patent CN201911026897.4 discloses that when nano silver is added to an aqueous polymer emulsion as an antibacterial property, the nano silver is likely to agglomerate and has a poor effect of releasing silver ions.
