Chromium-free environment-friendly metal film coating structure system

Abstract

The invention provides a chromium-free environment-friendly metal film coating structure system. The system comprises an organic compound substrate, a silicon-based hydrophilic deposition layer, an ionic bonding and sensitizing layer and an non-electrolytic metal coating, wherein the organic compound substrate is provided with at least one organic compound, the silicon-based hydrophilic deposition layer is deposited on the organic compound substrate to form a hydrophilic rough surface, the ionic bonding and sensitizing layer is formed on the silicon-based hydrophilic deposition layer and has a plurality of palladium ions, and the non-electrolytic metal coating is formed on the ionic bonding and sensitizing layer and has a plurality of metal ions. The multiple metal ions and the multiple palladium ions form a plurality of bonds, a surface of the non-electrolytic metal coating receives irradiation of a light source, and hydrogen gas and / or hydrogen compounds are moved out from between the silicon-based hydrophilic deposition layer as well as the ionic bonding and sensitizing layer and the non-electrolytic metal coating.

Description

technical field [0001] The invention relates to a coating structure, in particular to a coating structure manufactured by a low-cost, fast, environmentally friendly and pollution-free manufacturing process. Background technique [0002] In the middle of the 19th century, the economies and industries of all countries in the world developed at a high speed. During the manufacturing and development of machinery, automobiles, shipbuilding, aircraft and other industries, the needs for various improvements in mechanical strength, decoration or other special performance treatments on the surface of products gradually emerged. , Therefore, the British and the Russians independently designed metal electroplating methods, and with the maturity of the electrochemistry (Electrochemistry) theory, the electroplating principles and methods were gradually understood by the world and promoted to the world. At the end of the 19th century, it was discovered that after the reaction of silver ni...

[0004] However, the plastic electroplating process of the aforementioned prior art adopts hexavalent chromic acid Cr (VI) as the main solvent for the rough treatment of the ABS resin surface, but hexavalent chromic acid Cr (VI) is a harmful Carcinogenic substances, chromium dust or chromium vapor produced during the production process are inhaled by the human body, causing acute poisoning of the upper respiratory tract, oral mucosa, lungs, stomach, and kidneys. Accumulated in the human body for a long time, it is more likely to cause cell mutation and carcinogenesis risk; on the other hand, degreasing and surface roughening in the prior art require acid-base neutralization and then washing with deionized water to avoid excess solvents interfering with the chemical reaction in the next step, which is difficult in terms of process time and cost. shrink
