Preparation and Properties of Silicone Based Self-Deicing Coating

Abstract:

A silicone based self-deicing coating was prepared by blending of silicone solution and organics-coated NaCl deicing additive. The effects of deicing additive content and coating amount on freezing point of coating surface and adhesion force between ice and coating were investigated. The deicing durability of self-deicing coating was evaluated by immersion test. And the influence of silicone based self-deicing coating on friction coefficient and structure depth of asphalt pavement was researched. The experimental results showed that freezing point of coating surface and adhesion force between ice and coating decreased with the increase of the organics-coated NaCl content, freezing point and adhesion force of the self-deicing coating with 6wt.% organics-coated NaCl were-5.2°C and 24.5 N respectively. Immersion test results showed that the deicing performance had only a small reduction after immersion in water for 3 days,which indicated the self-deicing coating had good deicing durability. Moreover, silicone based self-deicing coating had slight influence on friction coefficient and structure depth of asphalt pavement due to the good permeability of silicone solution. The friction coefficient of asphalt pavement decreased by 10.4%, and the structure depth decreased by 6.1% when the amount of the self-deicing coating was 300 g/m².
