Embodiment 1

[0086] Under normal temperature and pressure, mix 90% oily solvent, 5% smooth and wear-resistant powder and 5% polyacrylate type hyperdispersant evenly, grind and disperse at a high speed of 2000r / min for 2 hours to obtain smooth and wear-resistant oily slurry A; Mix 15 parts of elastic resin, 2 parts of stain-resistant resin, 20 parts of curing agent, 0.2 parts of film-forming aid, and 53 parts of oily solvent, and mix them at high speed at 1000r / min for 0.5h to obtain self-healing coating B; then mix 10 parts % smooth and wear-resistant oily slurry A and 90% self-repairing coating B were mixed evenly and mixed at a high speed of 1000r / min for 0.5h to obtain a smooth and wear-resistant self-repairing coating. Sample number: SH-1.

Embodiment 2

[0088] Under normal temperature and pressure, mix 90% oily solvent, 5% smooth and wear-resistant powder and 5% polyacrylate type hyperdispersant evenly, grind and disperse at a high speed of 2000r / min for 4 hours to obtain smooth and wear-resistant oily slurry A; Mix 15 parts of elastic resin, 2 parts of stain-resistant resin, 20 parts of curing agent, 0.2 parts of film-forming aid, and 53 parts of oily solvent, and mix them at high speed at 1000r / min for 0.5h to obtain self-healing coating B; then mix 10 parts % smooth and wear-resistant oily slurry A and 90% self-repairing coating B were mixed evenly and mixed at a high speed of 1000r / min for 0.5h to obtain a smooth and wear-resistant self-repairing coating. Sample number: SH-2.

Embodiment 3

[0090] Under normal temperature and pressure, mix 90% oily solvent, 5% smooth wear-resistant powder and 5% polyacrylate hyperdispersant evenly, grind and disperse at a high speed of 2000r / min for 6 hours to obtain smooth wear-resistant oily slurry A; Mix 15 parts of elastic resin, 2 parts of stain-resistant resin, 20 parts of curing agent, 0.2 parts of film-forming aid, and 53 parts of oily solvent, and mix them at high speed at 1000r / min for 0.5h to obtain self-healing coating B; then mix 10 parts % smooth and wear-resistant oily slurry A and 90% self-repairing coating B were mixed evenly and mixed at a high speed of 1000r / min for 0.5h to obtain a smooth and wear-resistant self-repairing coating. Sample number: SH-3.

Abstract

The invention relates to the field of coatings, and especially to a smooth wear-resistant self-repairing coating for a flexible protective film of a mobile phone, and a preparation method thereof. Specifically, the disclosed smooth wear-resistant self-repairing coating comprises, by weight, 5-20 parts of a smooth wear-resistant oily slurry, 10-25 parts of elastic resin, 0.5-5 parts of antifouling resin, 10-30 parts of a curing agent, 0-1 part of a coalescing agent, and 30-80 parts of an oily solvent. A coating layer obtained by coating the coating has excellent smoothness, wear resistance and self-repairing performance.

Description

technical field [0001] The invention relates to a functional coating used for a flexible protective film of a mobile phone, in particular to a smooth wear-resistant self-repairing coating and a preparation method thereof. Background technique [0002] Due to the prevalence of mobile games in recent years, mobile phones are used more and more frequently, and the lifespan of mobile phone screens is relatively short, which is easy to scratch, resulting in blurred screens, wear and tear, and greatly reduces the experience of mobile games. Therefore, more stringent requirements are put forward for the smoothness and wear resistance of the mobile phone protective film. However, the ordinary mobile phone protective film on the market is obviously jerky and rough in sliding touch, which can no longer meet the user's needs for high-frequency sliding in the process of playing mobile games. Contents of the invention [0003] The object of the present invention is to provide a smooth...
