Embodiment 1
[0029] Water-based clay lubricant, prepared from the following raw materials in weight percent: talcum powder 30%, sodium carboxymethylcellulose 0.2%, diatomaceous earth 0.5%, sodium pyrophosphate 5%, aluminum stearate 1%, borax 5% %, polyethylene glycol 8%, monoglyceride stearate 0.8%, and the balance is water.
[0030] Stir the above thickener in the solution of borax and water until it becomes jelly, then add other solid mixtures and monoglyceride stearate, and stir thoroughly to obtain a suspended liquid lubricant with good friction performance and good spraying effect And easy to clean without pollution.
[0033] Stir the above-mentioned thickener in the solution of anhydrous sodium borate and water until it becomes jelly, add other solid mixtures and monoglyceride stearate, and the suspension liquid lubricant obtained after fully stirring has better friction performance and is easy to absorb. Cleaning without pollution, but the low viscosity leads to thin film formation.
[0036] Stir the above thickener into the solution of borax and water until it becomes jelly, add other solid mixtures and ethylene bisstearamide, and stir the obtained suspension liquid lubricant with poor friction performance and high viscosity. It is not easy to spray and does not meet the requirements of rolling pipes.

Abstract
The invention discloses a water-based clay lubricant, and aims at solving the problems of difficult cleaning, easy smoking, large pollution, easy conducting and danger of the existing water-based graphite lubricant and solving the problem of high frictional coefficients of the graphite lubricant. The water-based clay lubricant is characterized by being prepared from the following raw materials in percentage by weight: 10 to 90% of mineral clay, 0 to 5% of stearate, 0.1 to 5% of a thickening agent, 0 to 10% of polyethylene glycol, 1 to 40% of a phosphorous-containing compound, 5 to 30% of a boron-containing compound, 0 to 1% of other additives, and the balance of water. The water-based clay lubricant is an environmentally friendly water-based clay lubricant which is uniform to disperse, easy to spray, resistant to high temperature, good in lubricating effect, easy to clean, and free of pollution.
Description
technical field [0001] The invention relates to the technical field of mandrel lubricant preparation for hot-rolled seamless steel pipes, in particular to a water-based clay lubricant. Background technique [0002] Mandrel lubrication is an important part of metal plastic processing in hot-rolled seamless steel pipes. When hot-rolled steel pipes pass through the mandrel, it can improve the elongation coefficient and surface finish of the rolled pipe, prolong the service life of the mandrel and reduce the rolling pressure. As well as energy consumption, reducing or avoiding rolling accidents, all countries in the world are constantly improving mandrel lubricant technology. At present, the treatment of hot metal surfaces is mainly through water-based graphite lubricants, but many hidden dangers (such as electrical conductivity, difficult to clean, and heavy pollution) brought by it have attracted increasing attention. There have been a series of research programs on graphite-...
