Problems solved by technology

[0002] Alumina sol is a colloidal solution in which positively charged feathery alumina particles are dispersed in water. It is widely used in industry and can be used in chemical industry, textile, ceramics, food, etc., for example, it can be used as glass fiber, asbestos , ceramic fiber and other inorganic fibers; the treatment of textile fiber products with aluminum sol can make the products obtain good antistatic and anti-dust properties; it can be used as a catalyst carrier, etc., and the polishing ability of the existing polishing composition is poor , the dispersion of the abrasive is not good, and the stability of the composition is poor

Embodiment Construction

[0023] A chemical-mechanical polishing composition for stainless steel surface polishing, consisting of abrasives, accelerators, oxidizing agents, metal chelating agents, surfactants, and penetrating agents; the weight percentages of each component are as follows:

[0024] Abrasive 0.1-20% Accelerator 1-10%

[0025] Oxidant 1~15% Metal chelating agent 0.01~5%

[0026] Surfactant 0.01-5% Penetrant 0.01-1%.

[0027] The weight percent of each component described in the present invention is preferably as follows:

[0028] Abrasive 1~10% Accelerator 1~10%

[0029] Oxidant 5-10% Metal chelating agent 0.1-1%

[0030] Surfactant 0.1-1% Penetrant 0.1-0.5%.

[0031] The abrasive contains at least one or more mixtures of α-alumina, δ-alumina, γ-alumina, and θ-alumina, and the average particle size of the abrasive is between 100 and 1000 nm, preferably between 200 and 600 nm. Between, the abrasive is preferably α-alumina.

[0032] The polishing accelerator is one or a mixture of tw...
