Performance Evaluation of a Hydrophobically Modified Anti-Slide and Anti-icing Coating

Abstract

Two-component oil-based polyurethane and two-component water-based polyurethane were used as main raw materials, and a hydrophobic modified anti-slip snow coating was prepared by adding a sodium chloride modified snow melting agent which was subjected to zeolite-diatomite slow release treatment. The performance of the coating was evaluated. The viscosity test showed that the viscosity of the coating was 4200 MPa, which ensured the fluidity of the coating. The contact angle test shows that the coating has a contact angle of 99.2° and belongs to a hydrophobic surface. The friction coefficient and texture depth tested shows that the material has a friction coefficient and depth of texture up to 81BPN and 72.5mm. The research results show that the coating has certain hydrophobic ability, can hinder the road surface freezing, and can release the snow melting agent for a long time, prolong the ice-suppressing effect of the coating, and has good anti-sliding ability, which can ensure the safety of driving in r ice and snow weather.
