Embodiment 1

[0030] Example 1: A shower with a silver-white pearl appearance

[0031] Manually wipe and degrease the shower workpiece, and the degreasing agent is isopropanol;

[0032] 1) Spray a high-gloss primer layer on the substrate treated in step 1), using an acrylic system;

[0033] 2) Perform physical vapor deposition (physical vapor deposition) chrome plating on the workpiece treated in step 2), and then perform plasma modification, metal coating and color coating in sequence. The process parameters are:

[0034] a) Plasma modification: argon flow rate 50SCCM, oxygen flow rate 50SCCM, furnace vacuum 0.2Pa, activation time 5min, bias voltage 80V, ion source current 0.5A;

Abstract

The invention provides a pearl-like film coating method, relates to a coating process and provides the pearl-like film coating method for forming a structural colored film on the surface of a paint film by vapor deposition without adding any pigment. The pearl-like film coating method includes the steps of firstly, washing base material for oil removal; secondly, spraying high gloss base coat to the base material processed in the step 1; thirdly, coating a color film to a workpiece processed in the step 2 by PVD (physical vapor deposition); and fourthly, spraying finishing top coat to the workpiece processed in the step 3 to obtain the pearl-like workpiece.

Description

technical field [0001] The invention relates to a coating process, in particular to a coating method with a pearl appearance. Background technique [0002] Pearl is a transparent mineral with luster. Due to the continuous reflection and mutual interference of light through several layers of cleavage surfaces, it presents a dazzling luster. [0003] At present, the appearance of imitation pearls or artificial pearls is generally completed by dissolving nitrocellulose with various solvents, and then adding pigments to the solution to coat the resin beads. Most of the pigments in the above ingredients are hydroxides containing lead. The compound of neutral salt and alkaline lead carbonate, the use of this compound can make pearls have a good texture and luster, but after wearing, it will cause harm to the human body and pollute the environment, which has become a difficult problem to solve question. [0004] Chinese patent 200410024173.3 discloses a coating for artificial pea...
