  • the present invention relates to a spray nozzle for coating a vehicle flange and a method for coating a vehicle with glue.
  • the gluing process usually comprises a seam sealing step and an underbody protecting step, so that especially the sealing and the anti-corrosion treatment for vehicles can be achieved, and thus for example the wax can be prevented from discharging from the welding seam in the later step of wax injection in hollow cavity.
  • the PVC coating material In order to improve the airtightness, the sound insulation, the vibration resistance, the stone chip resistance and so on, the PVC coating material is widely used in the gluing process for vehicles.
  • the PVC coating material usually means the polyvinyl chloride paint, whose main ingredient is polyvinyl chloride resin, and the pigments, plasticizers, packings and so on can be added into the polyvinyl chloride resin to mix together so as to form a high solid content paint with a solid content of more than 90%.
  • the PVC coating material can be divided into two types, i.e. the seam sealing glue and the underbody paint.
  • the seam sealing glue has good flexibility, extensibility, rigidity and Resistance to abrasion and thus can take the effects of good airtightness, sound insulation and leakproof.
  • the underbody paint is mainly sprayed at the bottom of the vehicle body and the four wheel housings, has higher rigidity, hardness and high adhesive force, and can take the effects of vibration resistance, stone chip resistance and protection for vehicle body.
