What are the factors that affect the antibacterial activity of gel-coat resin ?

Feb 20, 2019

With the increasing variety and performance of gel coat resin, the application field of gel coat resin is expanding, currently in sanitary ware, shipbuilding, transportation, construction, entertainment, medical instrument housing, billboards, telephone booths and Security guards and other aspects have been applied. Antibacterial property is an important performance index of antibacterial gel coat resin, which directly affects the further development and application of antibacterial gel coat resin. Therefore, it is very important to study the factors affecting its antibacterial properties.

Silica sol was used as carrier. The composite inorganic antibacterial agent was prepared by loading nano-silver ions TiO2, ZnO2 and Al2(SOi3)3 on the silica-precipitated silica surface, and added to gelatin resin to prepare antibacterial. Gel coat resin. The preparation parameters, content and type of antibacterial agent and the preparation parameters of antibacterial gel coat resin were studied for the antibacterial properties of gel coat resin. The experimental results show that with the increase of sintering temperature, the antibacterial rate of antibacterial gel coat resin increases first and then decreases. When the antibacterial agent is sintered at 1000 °C, the antibacterial gel coat resin has the highest antibacterial rate; The antibacterial rate of the antibacterial gel coat resin is increasing, the antibacterial rate of the antibacterial gel coat resin is increased by more than 6 h; the antibacterial rate is gradually increased with the increase of the styrene content, and the antibacterial rate is increased when the styrene content is 10%. Up to 94%; with the extension of the stirring time, the antibacterial rate of the antibacterial gel coat resin also increased, and the antibacterial rate was 94% when the stirring time was 1h.
