TiO 2 particles with different diameter sol-gels improve the self-cleaning performance of acrylic resins.
first, micron-sized spherical TiO 2 particles were prepared using the package reaction product and the encased reaction product produced by the chemical reaction between urea and EtOH as a template. The size of the spherical TiO 2 can be adjusted by the ratio of the urea solution

. Spherical TiO 2 particles are mainly composed of sharp titanium ore.
the performance of acrylic resin
then use the above spherical TiO 2 particles to enhance the performance of acrylic resin. With TiO's addition 2, TiO 2's microstructive surface 2/acrylic coating is in the convex shape of the lotus leaf.
When TiO 2 is added by 30% (by weight), the corrosion resistance of the acrylic coating on the Q235 steel plate brush can be improved, with a water contact angle of 121.5 degrees on the surface of the TiO2/acrylic coating. Good self-cleaning performance is shown in the water, where the concentration of sand reaches 20% (weight). The composite coating shows the highest 5B rating measured by the Adhesive Test ASTM D-3359-02 (American Association of Testing and Materials).
the study has been published in Progress in Organic Coatings, volume 128.
