CONSTITUTION:A lubricating agent for mandrel bars, prepared by mixing (A) 5-45wt% graphite powder having 0.1-50mu particle diameter, with (B) 1-15wt% resin powder, e.g. vinyl acetate copolymeric resin, having 1-50mu particle diameter, (C) 0.1-3wt% dispersing agent, e.g. a nonionic surfactant, and (D) 0.1-3wt% hydrophobic agent, e.g. cobalt naphthenate, with (E) 45-95wt% water, and dissolving and dispersing the resultant mixture in the water in a ball mill by the wet method, and having 1.0-1.3 apparent specific gravity and 0.1-100 poises viscosity. EFFECT:Improved water and impact resistance and lubricity of dried coating films.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mandrel bar lubricant, which can be coated thickly in a short time by spraying or coating, and which has a short drying time in a low temperature range (room temperature to 100°C). Shorter and more
This invention relates to a mandrel bar lubricant that provides a dry coating film with excellent water resistance, instant impact properties, and lubricity.

The lubricant used in seamless steel pipe rolling, etc., which is most widely used today, is a mixture of oil (waste FDI) and graphite powder, which is sprayed onto the mandrel bar like a shower, or by first applying oil to the mandrel bar. This method provides lubricity by applying only waste oil (waste oil) and then sprinkling graphite powder as shown above.

In this case, since oil is used, there is a strong odor and odor.

On the other hand, water-based or water-soluble lubricants are considered as lubricants that do not use oil, but they may not be able to be applied thickly in a short period of time, or the coating film dries at low temperatures, i.e. from room temperature to about 100°C. Because it takes a long time to complete the process, it is not possible to move on to the next process, resulting in a major problem of lost time. Furthermore, since the dispersibility is insufficient, if the spray nozzle becomes clogged, a uniform coating film cannot be obtained, and a sufficient lubricating effect cannot be achieved.

The present invention was developed to eliminate these drawbacks, and since it is a water-based or water-soluble lubricant, it is excellent in the working environment, and is a suspension with excellent dispersibility, which prevents clogging of spray nozzles. The drying time of the paint film at low temperatures (from room temperature to 100°C) is short and reasonable, and the dried paint film has good water resistance and impact resistance. Furthermore, it is an object of the present invention to provide a mandrel bar lubricant for use in rolling seamless steel pipes, etc., which has excellent lubricity.

If the particle size exceeds 50 microns, the dispersibility of the mandrel bar lubricant will be poor, and sufficient adhesion will not be obtained. Further, the reason why the lower limit is set to 0 and IP is because it is normally available industrially and is suitable in consideration of the viscosity, stability, etc. of the mandrel per lubricant.

Therefore, the quantity of this resin powder is limited, that is, 1
When the lower limit of 15 to 11% is reached, the adhesion is not good and the lubricity of the coating film is also poor, making it unacceptable. Exceeding the upper limit is not acceptable because the dispersion stability will be poor and the lubricity of the coating film will also be poor.

However, the quantity of water releasing agent (d) is limited, i.e. 0.1
~ 8 weight% The reason for this is that if it is less than 0.1% by weight, the coating film will not dry in a short time in the low temperature range (room temperature to 100°C), and if it exceeds 8weight i1%, it will not be economical. Even from this point of view, it is unnecessary and impossible.

Next, if the quantity limit of [tree trunk] is exceeded, that is, the upper limit of 45 to 95 heavy ships, the apparent specific gravity and viscosity of the mandrel bar lubricant will decrease too much, and the dispersibility will deteriorate, so it is not possible, and the lower limit If the lubricant exceeds 500% from room temperature, the apparent specific gravity and viscosity will increase and the coating properties will deteriorate.
