The invention discloses a primer material, a preparation method and application thereof, an automobile glass bracket and a bonding composite material, and relates to the technical field of bonding and sealing. The primer material uses acrylic resin and polymethylene polyphenyl isocyanate as main raw materials; wherein, the molecular weight of the acrylic resin is 25000-200000g/mol, the hydroxyl value of the acrylic resin is 0-10mgKOH/g; the acrylic resin and polymethylene The mass ratio of base polyphenyl isocyanate is 1:0.6-2.1. The primer material prepared by using the raw materials of the primer material has very excellent adhesive properties, and can form an adhesive combination material with polyurethane and be used in the bonding of automobile side window glass brackets and glass. |
