AI Technical Summary
Existing composite panels and hydrophobic coatings have problems in preparation and stability, resulting in a high probability of icing on the underbody protection plate, which affects the reliability and safety of new energy vehicles. In addition, they are costly and not suitable for large-scale industrial production.
By adjusting the particle size and distribution of silica particles to achieve a Dv50 at the nanoscale and a distribution coefficient I ≤ 1.5, and combining them with amphiphilic dispersants containing ether functional groups and silanol and silyl ether functional groups, a stable hydrophobic layer is formed, thereby improving the stability and hydrophobicity of the coating.
This technology enables low-cost and efficient preparation of hydrophobic coatings, reduces construction difficulty, improves the stability and hydrophobic effect of the coating, reduces the risk of icing on the underbody protection plate, and enhances the reliability and safety of the vehicle.
