Embodiment Construction

[0009] Remove the putty layer and spray coating in the range of 1-2cm around the defect on the outer surface of the car to keep the defect clean. For the defects on the outer surface of the plastic bumper and exterior trim, use a cleaning solution (isopropyl alcohol or MEK / toluene Clean the dust and particles in the defect with a lint-free scouring cloth soaked with mixed liquid), and use a metal surface cleaning fluid (such as kerosene, gasoline, alcohol, etc.) for the defects on the outer surface of the metal body, and leave a small amount of cleaning in the defect Use a spray gun to dry the residual cleaning solution in the defect, and use the weathered stone powder with a particle size of 200-250 mesh, glue, cellulose and an appropriate amount of water (adjusted to The amount of water to toothpaste) in proportion (wherein weathered stone powder accounts for 70-80%wt, glue accounts for 10-20%wt, cellulose accounts for 2-5%wt and an appropriate amount of water). Mix to form ...

Abstract

The invention discloses a method for rapidly repairing the defect on the outer surface of an automobile through weathered stone. The method includes the steps of removing a putty layer and a spray-coated layer, within the range of 1-2 cm, around the defect on the outer surface of the automobile, removing dust and particles in the defect through a piece of scrubbing cloth wetted by cleaning fluid so that the defect can be kept clean, leaving a small amount of cleaning fluid in the defect, drying the cleaning fluid left in the defect through a spray gun, mixing weathered stone powder which is formed through high-temperature calcination and ball grinding and has the granularity of 200-250 mesh with glue to form thick colloid, putting the thick colloid in an extruder, evenly filling the defect with the thick colloid through the extruder, sealing the colloid through a transparent adhesive, and repeatedly conducting scrubbing till the surface is smooth. Due to the fact that the curing time is short, all repair procedures can be balanced, the whole repair time is greatly shortened, putty powder repair is reduced, labor hours and expenses are reduced, the work efficiency is improved, repair expenses are reduced and can be reduced by 50% or above, and the repair time is shortened to be within one day.

Description

technical field [0001] The invention relates to a method for repairing defects such as pits, cracks, scratches, scratches and local discoloration on the outer surface of an automobile.
