Problems solved by technology

At present, some commonly used metal polishing liquids still have problems such as easy scratches and low cutting efficiency when polishing 314L and 316L, and the preparation of these metal polishing liquids usually requires the addition of suspension stabilizers to facilitate long-term storage. These suspension stabilizers are usually chemicals containing organic matter, which are not conducive to subsequent water treatment and are not conduciv

Abstract

The invention discloses a metal polishing solution and a preparation method and application thereof. The preparation method comprises the steps that a first aluminum oxide precursor serves as a raw material and is calcined, the calcined material is subjected to wet ball milling, and the solid content of ball milling slurry is 30-55% till the particle size D<50> is 0.8-4 <mu>m; wet ball milling is carried out on a second aluminum oxide precursor until the solid content of the ball milling slurry is 30-70% until the particle size D<50> is 3-6 <mu>m; and the ball milling slurry obtained through calcination after-treatment, the ball milling slurry obtained through direct ball milling of the precursor, a surfactant, a defoaming agent, a corrosion inhibitor and a pH value regulator are mixed, and the metal polishing solution is prepared. According to the metal polishing solution, the prepared metal polishing solution can still have excellent suspension stability under the condition that a commercially available suspension stabilizer is not added, and the metal polishing solution is high in polishing efficiency, good in polishing quality and low in cost when being used for polishing stainless steel materials with the mark of 314L or 316L.

Description

technical field [0001] The invention relates to the technical field of polishing stainless steel materials, in particular to polishing media for polishing stainless steel materials such as grades 314L and 316L, and in particular to a metal polishing liquid and its preparation method and application. Background technique [0002] 314L and 316L are respectively a grade of stainless steel, which are widely used in metal products, mainly including other mechanical parts and structural parts such as furniture, bicycles, automobiles, and solenoid valves. Especially in recent years, because 314L and 316L are It has the characteristics of acid resistance, alkali resistance, and no bubbles. It is more and more used in precision daily necessities such as various watch cases, watch strap bottom covers, and mobile phone frames. However, with the further pursuit of product quality, the requirements for the surface of 314L and 316L are getting higher and higher, such as good surface brigh...
