Title:
アルミニウム微粉末の表面処理方法およびアルミニウム微粉末を懸濁させたクロム成分を含まない燐酸塩系水性防食塗料
Document Type and Number:
Japanese Patent JP4298901
Kind Code:
B2
Abstract:
A chromium-free corrosion inhibiting coating composition, which does not utilize harmful chromium compounds and can be used for corrosion inhibition of a metal surface, comprising a slurry mixture in which coated aluminum fine powder treated with a hydrophilic coupling agent is suspended in an acidic phosphate bonding solution and which can be stored in a refrigerator, is disclosed. A titanium-coupling agent is preferable to use as the coupling agent, which treats a surface of the aluminum fine powder. In this aqueous chromium-free corrosion inhibiting coating composition, 25 to 40% by weight of the aluminum fine powder a surface of which is treated with the coupling agent is suspended in the acidic phosphate bonding solution.
