Abstract

The invention discloses scratch-resistant and fingerprint-proof highlight piano black paint and a preparation method thereof, and application of scratch-resistant and fingerprint-proof highlight pianoblack paint. The scratch-resistant fingerprint-proof highlight piano black paint is composed of the following components in parts by weight: 40-65 parts of aliphatic polyurethane acrylic resin, 5-10parts of acrylic resin, 0.5-1 parts of a scratch-resistant and anti-fingerprint additive, 0.5-1 parts of a photoinitiator, 0.5-1 parts of a leveling agent, 0.5-1 parts of a dispersing agent, 0.5-1 parts of an antifoaming agent, 1-2 parts of a stabilizer, 1-2 parts of black paste and 30-40 parts of a solvent. A scratch-resistant and fingerprint-proof additive adopted by the invention can be subjected to directional cross-linking reaction with acrylic resin during UV photocuring, so that fluorine-containing molecular chains are gathered on the surface of a paint coating, and the scratch-resistant and fingerprint-proof effects are improved while the high glossiness of the paint coating is ensured.

Description

technical field [0001] The invention relates to the technical field of paints, in particular to a scratch-resistant and anti-fingerprint high-gloss piano black paint and its preparation method and application. Background technique [0002] With the continuous growth of my country's car ownership, cars are becoming more and more closely related to people's daily life. At the same time, the texture of automotive interior parts has attracted more and more attention from consumers. In recent years, due to the continuous development and innovation of automotive interior decoration technology, more and more decorative parts such as high-gloss piano black paint, electroplating, and INS have been applied to automotive interior parts, and the texture of interior parts has been continuously improved and enhanced. Consumers enjoy a sense of comfort and class. In particular, high-gloss piano black paint is used in large quantities for the decoration of large interior parts such as ins...
