Embodiment 1

[0051] This embodiment is used to illustrate the production method of the galvanized self-lubricating metal material of the present invention.

[0052] Preparation of self-lubricating agent composition: at 20°C, add 300 kg of deionized water to a 3000-liter enamel reactor, then add 10 kg of citric acid trivalent chromium compound, start the stirrer of the reactor to stir, and make the citric acid The trivalent chromium compound is completely dissolved in water, then adds 3 kilograms of citric acid under stirring condition, starts the stirrer rapidly, makes the citric acid dissolve rapidly, then adds 12 kilograms of silicon dioxide content and is the alkaline silica sol of 40% by weight, A lubricant composition with a pH of 6 was obtained after stirring for 5 minutes. It is determined by infrared spectrum analysis that the self-lubricating agent composition contains a large amount of -COOH, Si-O-, and it is determined by spectrophotometry that it contains Cr 3+ , thus indicati...

Embodiment 2

[0069] This embodiment is used to illustrate the production method of the galvanized self-lubricating metal material of the present invention.

[0070] Preparation of self-lubricating agent composition: at 25°C, add 500 kg of deionized water to a 3000-liter enamel reaction kettle, then add 50 kg of trivalent chromium gluconate, start the stirrer of the reaction kettle to stir, and make the gluconic acid The trivalent chromium compound is completely dissolved in water, then add 20 kg of maleic acid under stirring, start the stirrer quickly to dissolve the maleic acid quickly, and then add 25 kg of alkaline silicon with a silicon dioxide content of 30% by weight Sol, stirred for 3 minutes to obtain the composition containing silica sol provided by the present invention, with a pH value of 4. It is determined by infrared spectrum analysis that the self-lubricating agent composition contains a large amount of -COOH, Si-O-, and it is determined by spectrophotometry that it contains...

Embodiment 3

[0085] This embodiment is used to illustrate the production method of the galvanized self-lubricating metal material of the present invention.

[0086] The preparation of self-lubricating agent composition: add 500 kilograms of deionized water in the enamel reactor of 3 cubic meters, then add 50 kilograms of chromium gluconate trivalent chromium compound, start the stirrer of reactor to stir, make chromium gluconate trivalent chromium compound The chromium compound is completely dissolved in water, and then 20 kg of formic acid is added under stirring conditions, and the stirrer is quickly started to dissolve the formic acid quickly. Then add 20 kg of alkaline silica sol with a silicon dioxide content of 20% by weight, and stir evenly to obtain the composition containing silica sol provided by the present invention. It is determined by infrared spectrum analysis that the self-lubricating agent composition contains a large amount of -COOH, Si-O-, and it is determined by spectro...

Abstract

The invention relates to a galvanized self-lubricating metal material which comprises a galvanized metal substrate and a self-lubricating coating positioned on the galvanized metal substrate, wherein the self-lubricating coating is a product after a self-lubricating agent composition is solidified; the self-lubricating agent composition contains a trivalent chromium compound, silica gel and organic carboxylic acid and has the pH value of 4-7. Because the galvanized self-lubricating metal material is formed by solidifying the self-lubricating agent composition which contains the trivalent chromium compound, the silica gel, water and the organic carboxylic acid, the galvanized self-lubricating metal material not only has high lubricating property and corrosion resistance, but also can greatly reduce the requirement on the substrate of the galvanized self-lubricating metal material, and a hot dip galvanized plate with large surface roughness volatility and low price can be used as the substrate, thus the galvanized self-lubricating metal material has stronger market competition and higher economic benefit and represents the development direction of self-lubricating plates.

Description

technical field [0001] The invention relates to a galvanized self-lubricating metal material. Background technique [0002] Galvanized self-lubricating steel sheet is a galvanized steel sheet product with a thin organic coating on the surface. This product does not need to be coated with anti-rust oil because the organic coating has self-lubricating function to prevent the galvanized steel sheet from rusting during transportation and storage. The packaging process can be simplified, and the production and transportation costs can be reduced. Therefore, galvanized self-lubricating steel sheet has received extensive attention in the industry. [0003] Japanese iron and steel companies began to study galvanized self-lubricating steel sheets in the mid-1980s, and realized commercial production of galvanized self-lubricating steel sheets in the 1990s. There are mainly steel companies such as Kawasaki and Nippon Steel, and their galvanized self-lubricating sheets are also various...
