Abstract

The invention relates to black single-component solid color paint for automobile repair and a preparation method thereof. The black single-component solid color paint is prepared from the following components in parts by weight: 2.0-4.0 parts of carbon black pigment, 20.0-25.0 parts of resin, 18.4-21.4 parts of solvent, 45-50.0 parts of cellulose acetate butyrate, 2-8 parts of dispersing agent, 0.3-0.5 part of rheological aid, 0.02-0.05 part of flatting agent and 0.4-1 part of ultraviolet light absorbing agent. Compared with the prior art, the blackness of the solid color paint prepared by the method provided by the invention is greatly improved, and the hue of the prepared solid color paint is more partial to blue phase; and the prepared solid color paint has the advantages of excellent storage stability, flexibility, impact resistance, weather resistance and interlayer adhesive force, high drying speed and the like, and is more suitably used as automobile repair paint.

Description

technical field [0001] The invention relates to an automobile repair paint and a preparation method thereof, in particular to a black one-component solid color paint for automobile repair and a preparation method thereof. Background technique [0002] Black cars occupy a large proportion of the cars on the market now, so black one-component solid-color paint is an indispensable component in the car refinish paint system. [0003] General industrial black paint cannot meet all the requirements in terms of storage stability, drying performance, adhesion, flexibility, impact resistance, weather resistance, blackness and hue, especially drying performance, blackness and hue. It is very difficult to meet the requirements, and the details are as follows: [0004] Drying performance: The black one-component solid color paint for automobile repair requires that it can dry naturally within 2 to 3 minutes after spraying. However, most of the existing industrial paints are mostly two...
