Embodiment 1

[0011] A water-based lubricant prepared from the following raw materials in weight percent: montmorillonite 25%, sodium stearate 2%, zinc stearate 2%, methyl hydroxypropyl cellulose 0.3%, pentaerythritol 5%, Polyethylene glycol 5%, the balance is water.

[0012] The above-mentioned methyl hydroxypropyl cellulose and sodium stearate are first heated to 50°C in a solution of pentaerythritol, polyethylene glycol and water. o C. Stir to jelly, add other solid mixture and stir well to obtain a suspended liquid lubricant with good friction performance, good spraying effect and easy to clean and pollution-free.

Embodiment 2

[0014] A water-based lubricant prepared from the following raw materials in weight percent: montmorillonite 25%, sodium stearate 1.5%, zinc stearate 2%, methyl hydroxypropyl cellulose 0.1%, pentaerythritol 5%, Polyethylene glycol 5%, the balance is water.

[0015] The above-mentioned methyl hydroxypropyl cellulose and sodium stearate are first heated to 50°C in a solution of pentaerythritol, polyethylene glycol and water. o C. Stir to jelly, add other solid mixture and stir well to obtain a suspension liquid lubricant that has a good spraying effect and is easy to clean and pollution-free, but the viscosity is low, the fluidity is too good, and the thickness of the hanging film is relatively thin.

Embodiment 3

[0017] A water-based lubricant prepared from the following raw materials in weight percent: montmorillonite 25%, sodium stearate 3.8%, zinc stearate 2%, methyl hydroxypropyl cellulose 0.5%, pentaerythritol 5%, Polyethylene glycol 5%, the balance is water.

[0018] The above-mentioned methyl hydroxypropyl cellulose and sodium stearate are first heated to 50°C in a solution of pentaerythritol, polyethylene glycol and water. o C. Stir to a jelly, add other solid mixtures and stir well to obtain a suspending liquid lubricant with good friction performance, but high viscosity, poor fluidity, difficult to spray, and unable to perform spray lubrication operation.

Abstract

The invention provides a water-based lubricant, and aims is to solve the problem of difficult cleaning and heavy pollution of a water-based graphite lubricant and to improve the problem of a high friction coefficient of a graphite-free lubricant, and the water-based lubricant is environmentally-friendly, uniform to disperse, easy to spray and easy to clean. The water-based lubricant is characterized in that the water-based lubricant is prepared from the following raw materials by weight percentage: 10%-60% of montmorillonite, 2%-8% of sodium stearate, 0%-5% of zinc stearate, 0.1%-5% of a thickener, 0%-10% of pentaerythritol, 0%-10% of polyethylene glycol, 0.5%-1.5% of a preservative and balance of water.

Description

technical field [0001] The invention relates to an environment-friendly water-based lubricant with uniform dispersion, easy spraying, easy cleaning and no pollution. Background technique [0002] At present, the treatment of hot metal surfaces is mainly through water-based graphite lubricants, but its disadvantages such as difficult cleaning and heavy pollution have attracted increasing attention. At present, there have been a series of research programs on graphite-free lubricants, but there are still some problems in their relative lubricating properties. Contents of the invention [0003] The invention aims to solve the problems of difficult cleaning and heavy pollution of common water-based graphite lubricants, and provides a water-based lubricant. The technical problems to be solved by the present invention can be realized through the following technical solutions. [0004] A kind of water-based lubricant, it is prepared from by following weight percent raw material...
