Silicon-zirconium composite super-hydrophilic abrasion-resistant coating

The invention relates to a silicon-zirconium composite super-hydrophilic abrasion-resistant coating. The silicon-zirconium composite super-hydrophilic abrasion-resistant coating comprises the following components in parts by weight: 5-30 parts of single-layered zirconium hydrogen phosphate, 10-50 parts of silica sol containing sulfonic acid groups, 20-30 parts of a silane coupling agent and 30-60 parts of an alcohol solvent. A preparation method of the silicon-zirconium composite super-hydrophilic abrasion-resistant coating comprises the following steps: ultrasonically dispersing the single-layered zirconium hydrogen phosphate in the alcohol solvent to obtain single-layered dispersed zirconium hydrogen phosphate, blending and compounding the single-layered dispersed zirconium hydrogen phosphate with the silica sol containing the sulfonic acid groups, then adding the silane coupling agent, simultaneously adding acid, adjusting pH value of a system to be 3-5, and carrying out cohydrolysis reaction for 1-8 hours to obtain the silicon-zirconium composite super-hydrophilic abrasion-resistant coating. The silicon-zirconium composite super-hydrophilic abrasion-resistant coating is high in hydrophilicity, fog resistance, water resistance and weather resistance, and longer in service life; a coating prepared by the coating is high in hardness, abrasion resistance, scratch resistance, fingerprint resistance and stain resistance.
