Chinese patent CN 105200433A discloses a stainless steel liquid polishing wax and its preparation method. The main components of this polishing wax are wax, fatty acid, emulsifier, surfactant and abrasives. Although this liquid wax is more difficult to clean than solid wax However, because the components still contain wax, grease and other difficult-to-clean substances, the workpieces after fine polishing still need to be cleaned by auxiliary external forces such as ultrasonic waves or spraying.
Chinese patent CN104403572A discloses a liquid polishing wax and its preparation method. Its main components are stearic acid, liquid paraffin, brightener, emulsifier and aluminum oxide, etc. This liquid polishing wax also contains paraffin, stearic acid, etc. Substances that also make the rear surface difficult to clean

Abstract

The invention aims to provide a water-soluble elaborate polishing liquid and a preparing method thereof. The water-soluble elaborate polishing liquid has high cutting force on metal products, especially aluminum alloy, and meanwhile the surface is easy to clean after elaborate polishing. The water-soluble elaborate polishing liquid comprises, by weight, 25-45% of an abrasive material, 1-5% of polydextrose, 5-10% of polyhydroxyl synthetic ester, 10-20% of erucic acid, 5-15% of a saponifying agent and 15-50% of water. By using all the water-soluble auxiliaries for replacing oil or fat substanceson the basis of keeping lubricity, brightness and other performance, the surface is easy to clean after polishing, and thus the water-soluble elaborate polishing liquid is suitable for elaborate polishing of aluminum alloy. The water-soluble elaborate polishing liquid has the polishing performance equivalent to that of conventional liquid wax, however, the water-soluble elaborate polishing liquidcan be cleaned up only through soaking after polishing, so that the water-soluble elaborate polishing liquid is suitable for elaborate polishing of a metal workpiece the surface of which needs mirrorlight and thus has quite high actual application value.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment, and relates to a water-soluble fine polishing liquid, in particular to a water-soluble fine polishing liquid which has good cutting force on aluminum alloy and other metal products and is easy to clean the surface after fine polishing, and a preparation method thereof. Background technique [0002] In order to improve the smoothness and smoothness of the surface of metal or metal products, it is often necessary to polish the surface during its processing. Due to their special properties, aluminum alloy products are widely used and occupy an extremely important position in the hardware market. Aluminum alloy products need to be polished in surface treatment, which not only makes the appearance of aluminum alloy products have a bright appearance, but also uniform The smooth surface can disperse and reduce the adsorption of corrosive media and improve the corrosion resistance. At pr...
