The component A and the component B are collectively called polyurethane combined material. The preparation of the existing antibacterial polyurethane elastomer coating is usually to add an antibacterial agent directly into a reaction kettle, so that the safety, durability, heat resistance and weather resistance of the antibacterial polyurethane elastomer coating are poor. Therefore, the mode of adding the antibacterial agent is adopted, the physical properties of the main material are sacrificed to a certain extent, and the long-term service performance of the material is influenced. In order to enhance the usage efficiency of the antibacterial agent, the antibacterial agent (such as metal ions, organic cations, etc.) is usually loaded in the micropores of the porous material by ion exchange, coprecipitation, or co-agglomeration, so that it is tightly bound with the micropores and then slowly released.
And the isocyanate can be partially crystallized at low temperature or after being stored for a long time, so that the isocyanate raw material is generally heated and liquefied before being used for preparing the polyurethane coating in the production process of the polyurethane elastomer coating. And other materials are heated to a certain temperature for reaction. If the reaction temperature of the polyurethane elastomer coating in the production process cannot be effectively controlled, adverse reactions are easy to occur, the regularity among molecules is influenced, and the quality and the production efficiency of products are influenced.
