Problems solved by technology

Existing shifter panel paint, commonly used epoxy resin paint (UV paint) or polyurethane paint (PU paint), is cured and baked through a layer of primer and covered with a layer of color paint, which has poor weather resistance, Defects such as scratch resistance, unstable paint layer, poor decoration, etc. The relatively strict light aging test fails to meet the requirements, and the cracking of the paint is serious, which has a great impact on the functionality and aesthetics of the shifter panel.

Abstract

The invention discloses a shifter panel paint, which comprises a primer containing an acrylic resin, fumed silica, n-butyl alcohol and a white pigment, a color paint containing an acrylic resin, fumedsilica, n-butyl alcohol and a color pigment, and a varnish containing polyurethane, a light stabilizer, a heat stabilizer and a toughening agent, wherein the toughening agent is dioctyl phthalate. The paint disclosed by the invention is strong in toughness, good in matching property between coatings, strong in adhesive force between the coatings and between the paint and a panel, free from generating an interlayer interface under the action of external force, not easy to fall off, is uniform and transparent in color, excellent in appearance decoration performance and strong in weather resistance, can achieve good anti-aging effect under severe test conditions after being coated, and further has excellent scratch resistance. The invention also provides a coating process of the shifter panel paint, wherein the process is simple and easy to operate, uniform and stable in paint coating and excellent in product performance.

Description

technical field [0001] The invention relates to the field of automobile painting, in particular to a shifter panel paint and a coating process thereof. Background technique [0002] Automobile safety, appearance, and body weight reduction are the current development trends of new energy vehicles. Therefore, higher requirements are placed on the environmental protection, weather resistance, craftsmanship, and appearance decoration of the materials used in the automotive central control system. The automotive central control system has strict and harsh requirements on the coating performance, which cannot be achieved by a single coating, so it needs to be achieved through a combination of multi-layer coatings. The control system plays a certain protective role, and it also has a good appearance decoration. [0003] For coated shifter panels, paint weatherability becomes a major factor affecting product performance and appearance requirements. The existing shifter panel paint...
