example 1

[0016] First, take 1kg of scouring wastewater sludge, add it to a beaker, and then move it into the oven, and dry it at 95°C to a moisture content of 10%. Add 4L of petroleum ether to the dried sludge, stir and extract for 1h, then filter. Collect the filtrate, place the filtrate in a beaker, add 100 mL of 10% sulfuric acid solution, and heat it to 60°C, keep stirring for 30 minutes, stop heating, and let stand for layering, and collect the upper layer solution; The upper layer solution was placed in a beaker, and then 300 mL of 10% sodium hydroxide solution and 100 mL of absolute ethanol were added, stirred for 30 minutes, and allowed to stand for layering. Collect the organic layer and place the organic layer in the distillation device to perform Heat to 80°C, distill for 1h, transfer the distilled liquid to a rotary evaporator, and rotary evaporate to 2 / 3 of the original volume to obtain a lanolin concentrate; then weigh 20g diatomaceous earth, 10g diamond powder and 15g oxid...

[0022] First, take 2kg of wool scouring wastewater sludge, add it to a beaker, then move it into the oven, and dry it at 100°C to a moisture content of 13%. Add 5L of petroleum ether to the dried sludge, stir and extract for 2h, then filter. Collect the filtrate, place the filtrate in a beaker, add 150 mL of 10% sulfuric acid solution, and heat it to 65°C, keep stirring for 35 minutes, stop heating, and let stand for stratification, and collect the upper layer solution; The upper layer solution was placed in a beaker, and then 350 mL of 10% sodium hydroxide solution and 150 mL of absolute ethanol were added, stirred for 35 minutes, and allowed to stand for layering. Collect the organic layer, and place the organic layer in the distillation device. Heat to 83℃, distill for 2h, transfer the distilled liquid to a rotary evaporator, and rotary evaporate to 2 / 3 of the original volume to obtain a lanolin concentrate; then weigh 25g diatomaceous earth, 13g diamond powder and 18g oxidat...

Abstract

The invention discloses a method for preparing a metal polishing agent and belongs to the technical field of preparation of polishing agents. The method comprises the following steps: first, wool-washing wastewater sludge is treated by using an acid and an alkali, thereby extracting lanolin in the wool-washing wastewater sludge; then, diatomite, diamond micro-powder and the like are subjected to ball milling, thereby obtaining an abrasive material; and finally, the obtained lanolin and abrasive material are blended with surfactants and organic acids, thereby obtaining the metal polishing agent. In the method, citric acid is blended with the surfactants as a chelating agent, and can be used for quickly removing rust and oil dirt on a metal surface. The metal polishing agent prepared according to the method disclosed by the invention is stable in performance and has the advantages that oil dirt and rust spots on the metal surface can be effectively removed, and then the metal surface can be kept shiny and bright; meanwhile, a protective film layer is formed on the metal surface, so as to preventing the air from corroding metal; in addition, no fluorine-containing compound or phosphorous compound is contained in the metal polishing agent, so that the metal polishing agent is safe and environmentally friendly; and the metal polishing agent has the characteristics of being wide in application scope, stable in polishing effect, convenient to use, and efficient.

Description

Technical field [0001] The invention discloses a preparation method of a metal polishing agent and belongs to the technical field of polishing agent preparation. Background technique [0002] Polishing refers to the use of mechanical, chemical or electrochemical effects to reduce the surface roughness of the workpiece to obtain a bright, smooth surface. Polishing cannot improve the dimensional accuracy or geometric accuracy of the workpiece, but aims to obtain a smooth surface or mirror gloss, and sometimes it is also used to eliminate gloss (matting). Polishing usually uses a polishing wheel as a tool. The polishing wheel is usually made of multiple layers of canvas, felt or leather. The two sides are clamped by metal discs. The rim is coated with a uniform mixture of fine abrasives and grease. Agent. [0003] At present, the commonly used polishing agent products on the market are often operated by intermittent means when they are used, with high labor intensity, low unit outpu...
