example 1

[0018]Pour nano-sized α-alumina and absolute ethanol into No. 1 beaker at a mass ratio of 1:20, and move No. 1 beaker into an ultrasonic disperser. Add a dopamine solution with a mass concentration of 2.5g / L that is 0.3 times the mass of absolute ethanol in the beaker, and continue ultrasonic dispersion for 15 minutes. Under the condition of heating, stirring and mixing for 30 minutes, the nanometer α-alumina dispersion was obtained; pour ethyl orthosilicate and absolute ethanol into the No. 2 beaker at a mass ratio of 1:10, and move the No. In the instrument, under the condition of ultrasonic frequency of 60kHz, ultrasonically disperse for 20min to obtain tetraethyl orthosilicate dispersion; then take 80 parts of nanometer α-alumina dispersion and 20 parts of tetraethyl orthosilicate Dispersion liquid, 8 parts of ammonia water with a mass fraction of 15%, first pour the nano-α-alumina dispersion liquid into a four-necked flask with a stirrer, set the stirring speed at 600r / mi...

Abstract

The invention discloses a preparation method of a special solid polishing agent for a stainless steel product, and belongs to the technical field of metal processing aids. The method comprises the following steps that the coated modified aluminum oxide and absolute ethyl alcohol are mixed firstly and then undergo ultrasonic dispersion, then the treatment is carried out by using polyvinylpyrrolidone, the coated modified aluminum oxide dispersion liquid is prepared, then the coated modified aluminum oxide dispersion liquid and the monomer acrylamide are mixed, under the action of a cross-linkingagent and an initiator, the monomer is polymerized to form the three-dimensional size network gel, then the dopamine is used for assistant, after the reaction is finished, vacuum drying is carried out, the dry gel is prepared, then the dry stearic acid, the linoleic acid, the citric acid and the oxalic acid are mixed, then heating and melting are carried out, then the dry gel is added, after stirring and mixing are achieved, injection molding, cooling and forming, and demolding are carried out, and the special solid polishing agent for the stainless steel product is obtained. According to thepreparation method, the prepared special solid polishing agent for the stainless steel product has an excellent polishing effect, and the glossiness is effectively improved.

Description

technical field [0001] The invention discloses a preparation method of a special solid polishing agent for stainless steel products, belonging to the technical field of metal processing aids. Background technique [0002] Because of its hygienic, beautiful appearance, economical and durable characteristics, stainless steel products are widely used in the catering industry such as canteens and hotels, food and pharmaceutical processing and manufacturing industries, and have become more and more popular in recent years with the improvement of living standards. The favor of urban residents, product sales are very large. Therefore, the polishing industry of stainless steel products develops rapidly, and various solid polishing agents required for its polishing process also arise at the historic moment, and the consumption continues to increase. [0003] Polishing is generally made of a cloth or soft material (called a cloth wheel). Using the high-speed rotation of the cloth...
