Problems solved by technology

[0004] The technical problem to be solved by the present invention is to solve the problem that silicon dioxide polishing is commonly used in metal polishing at present. Although better surface effects can be obtained, the polishing time is long, and too long polishing is likely to cause corrosion defects on the metal surface. Provide a metal polish

preparation example Construction

[0020] The preparation method of polishing material comprises the following steps:

[0021] (1) Take methyl acrylate and add deionized water at a mass ratio of 1:12, heat up to 50~60°C, then add ammonium persulfate with 20~25% of the mass of methyl acrylate, stir at 300r / min, 60~70°C Mixed for 4~6h, cooled to room temperature to obtain the cooled product;

[0022] (2) Take the cooling material and add deionized water at a mass ratio of 1:50, and ultrasonicate at 200W for 15~20 minutes to obtain an ultrasonic product, and take the ultrasonic product and add cerium nitrate and hexamethylenetetramine at a mass ratio of 100:1:40 to mix , Stir and mix at 70~75°C for 1~2h, centrifuge, take the precipitate, wash and dry it with distilled water, and obtain the polishing material.

[0023] Surfactant: A. Take isophorone diisocyanate, heat up to 40~50°C and stir and mix for 30~40min, then add lauryl polyoxyethylene ether-3 with 70~80% isophorone diisocyanate quality, in Stir and mix a...

Abstract

The invention discloses a metal polishing agent and belongs to the technical field of metal surface treatment. According to the metal polishing agent, methyl methacrylate is used as a raw material andpotassium persulfate is added and used as an initiator; monodisperse microspheres are synthesized through adopting a soap-free emulsion polymerization method; then cerium nitrate is used as a ceriumsource and hexamethylenetetramine is used as a slow-release precipitating agent, and uniform coating of nanoparticles of cerium dioxide on the surface of an inner core of methyl methacrylate is realized; polyoxyethylene lauryl ether, isophorone diisocyanate and polyethylene glycol-400 are used as raw materials and are subjected to nucleophilic addition reaction to prepare a surfactant with a hydrophobic group and a hydrophilic group, so that the metal surface hydrophoic performance of metal is improved, subsequent corrosion prevention of a metal surface is improved and protection on the metalis formed. By adopting the metal polishing agent, the problems of a current metal polishing agent that the polishing time is long and corrosion defects are easy to cause on the metal surface due to too-long polishing are solved.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment, and in particular relates to a preparation method of a metal polishing agent. Background technique [0002] There are various methods of metal surface treatment, such as electroplating, electrophoresis, chemical treatment, surface polishing and so on. During the use of metal products, due to oxidation in the air, humidity or exposure to chemical substances and corrosive gases, etc., the surface of the metal products will be corroded, and dirt and oil will be attached. In order to increase the surface finish of the metal products, it is often necessary to treat the metal products Polished finish. Polishing agents are often added during the polishing process to improve the brightness of metal parts and clean the metal surface. Polishing is a grinding action. The polishing agent "tears" the surface layer, and the lower layer maintains its fluidity in an instant, and before solidifi...
