The invention discloses a multiple self-crosslinking water-based hybrid resin and a preparation method and application thereof. In parts by weight, the hybrid resin comprises the following components: 5-15 parts of epoxy resin, 5-20 parts of fatty acid, 0.2-1 part of unsaturated dibasic acid, 5-15 part of polyisocyanate, 1-3 part of water-soluble functional monomer, 0.01-0.05 part of catalyst, 1-3 part of chain extender, 0.2-1.5 part of silane coupling agent, 5-15 parts of silica sol, 1-3 parts of neutralizer, 5-10 parts of cosolvent, 30-70 parts of deionized water. By introducing epoxy chain, polyurethane chain, unsaturated chain, siloxane chain, etc. into the resin, the present invention endows the water-based hybrid resin with excellent drying properties, initial and dry water resistance, adhesion, salt spray resistance and hardness It also has the characteristics of simple process operation and low cost. |
