Ultra-fast dry repair varnish for automobiles and preparation method thereof

Abstract

The invention discloses an ultra-fast dry repair varnish for automobiles and a preparation method thereof. The composition of the varnish comprises the following components in certain percentage by weight: solvent, modified additive, varnish film forming matrix, flatting agent 1, flatting agent 2, drier, light stabilizer 1, light stabilizer 2 and curing agent. After the repair varnish of the invention is used, at the temperature of below 25 DEG C, the repair varnish is surface dry in 10 minutes, can not stick dust, and can be waxed and polished after 1 hour. Compared with the prior art, the baking time is reduced, the energy source is saved and the spraying efficiency is improved.

Description

technical field The invention relates to a chemical coating and a preparation method thereof, in particular to an ultra-fast-drying repair varnish for automobiles and a preparation method thereof. Background technique The car body is coated with a layer of paint film for protection and decoration, but the paint film is often damaged during use. At this time, the car owner needs to put it in the repair shop for re-spraying. The characteristics of car refinish paint are self-drying, quick repair, and easy toning; as an indispensable part of car maintenance, car refinish paint has gradually developed into an independent industry. Car refinish paint is different from the original car paint that people are familiar with. It needs to match the various colors of the car. It can be dried and baked during the construction process. , gloss, durability and other aspects must be consistent, to repair without leaving traces. At present, the surface dry time of the known car repair varn...

AI Technical Summary

Problems solved by technology

At present, the surface dry time of the known car repair varnish after spraying is 60 minutes at a temperature of 25°C. After drying overnight, it is waxed and polished. If the surface dry time is too long, it will easily cause paint film defects such as sticky dust, which greatly affects post-treatment. The process and performance objectively prolong the time for customers to pick up the car, which cannot meet the needs of picking up the car within 1-2 hours
