Abstract

The invention discloses degreasing powder used for surface treatment of nonferrous metals and a method for preparing the same. The compositions by weight portion of the degreasing powder are: 20 to 45 portions of sodium carbonate, 30 to 55 portions of sodium metasilicate pentahydrate, 20 to 35 portions of trimeric sodium phosphate, and 3 to 20 portions of nonyl phenol polyethenoxy ether. The method for preparing the degreasing powder is as follows: firstly, the sodium carbonate and the trimeric sodium phosphate are uniformly mixed and stirred; secondly, the nonyl phenol polyethenoxy ether and the sodium metasilicate pentahydrate are added, and then the finished product is obtained after uniform stirring. The degreasing powder has strong inhabitation ability, is applied to surface treatment of copper, zinc and a plurality of nonferrous metals and alloys of the nonferrous metals, has good cleaning effect on various oil stains such as engine oil, lubricating oil, anticorrosive oil, animal and vegetable oil and so on, and is nontoxic, nonflammable, wide in application range, easy to process waste solution and favorable for environmental protection.

Description

Degreasing powder for non-ferrous metal surface treatment and preparation method thereof technical field The invention relates to a degreasing powder used for degreasing and decontaminating the surface of nonferrous metals and their alloy products, and also relates to a preparation method of the degreasing powder. Background technique In the production of copper, zinc, aluminum, magnesium and other non-ferrous metals and their alloy products, especially in the electroplating production, surface treatment for degreasing and decontamination is often required, which directly affects the electroplating quality of non-ferrous metal products. Various degreasing agents currently used for surface treatment of non-ferrous metals have unsatisfactory effects due to their components, content and preparation methods. They cannot simultaneously inhibit corrosion of various non-ferrous metals, and the degreasing agent is single, and the application range is limited. Contents of the inve...
