Abstract

The invention discloses a fingerprint-resistant treating agent for stainless steel and in particular discloses an environment-friendly chrome-free fingerprint-resistant treating agent for stainless steel. The treating agent is characterized by comprising the following raw materials by weight: 7-10% of ureidopropyl silane, 5-10% of acrylic-modified resin, 3-8% of water-dispersible silicon dioxide and the balance of mixed solvents. The treating agent is colorless to faint yellow transparent liquid. The treating agent can be painted or sprayed on the surface of the stainless steel to form a uniform and exquisite environment-friendly chrome-free fingerprint-resistant coating. The treating agent is safe and environment-friendly, does not contain toxic and harmful components and can not cause secondary pollution to the environment.

Description

Technical field [0001] The invention discloses a fingerprint resistant treatment agent for stainless steel, in particular a fingerprint resistant treatment agent for chromium-free environmentally friendly stainless steel. Background technique [0002] Stainless steel is easy to adhere to human fingerprints during processing and use, which not only affects its aesthetics, but also affects its corrosion resistance and subsequent processing performance. Therefore, it is necessary to carry out anti-fingerprint treatment. The traditional anti-fingerprint treatment is chromate passivation treatment and organic coating type anti-fingerprint treatment. [0003] Chromate passivation treatment is not only inconvenient to use, but also hexavalent chromium will cause greater harm to human health and cause greater environmental pollution. The Directive on Waste from Electrical and Electronic Equipment (WEEE) and the Directive on Restricting the Use of Certain Hazardous Substances in Electrical...
