Abstract
The invention discloses aqueous graphite lubricating agent, which comprises the following components in part by weight: 10 to 55 weight parts of natural or artificial graphite, 0.5 to 1 part of rare earth oxide, 0.5 to 1.5 parts of nanoscale graphite powder, 1 to 5 parts of white graphite, 2 to 5 parts of molybdenum disulfide, 1 to 5 parts of nano aluminum oxide, 3 to 5 parts of acetone, 5 to 10 parts of ethanol, 2 to 5 parts of dispersant, 5 to 10 parts of methylcellulose, 5 to 10 parts of sodium silicate and 20 to 30 parts of distilled water. The rare earth oxide is the oxide of at least one of the rare earth elements including lanthanum, cerium and praseodymium. The aqueous graphite lubricating agent is low in price, does not pollute the environment, and can repair the damaged surface of the equipment automatically and improve the application temperature range and lubricating effect.
Description
Technical field:
The present invention relates to lubricant, particularly a kind of aqueous graphite lubricating agent that is applicable at high temperature use.
Background technology:
The lubricant that uses in oiling system at present all is the basic oils with mineral oil or synthetic, also has to add the oiliness graphite such as graphite and other additive in mineral oil.These lubricants at high temperature decompose and burning easily because be take mineral oil as medium; Simultaneously at high temperature graphite will lose its wear resisting property, cause temperature limit to diminish, and the cost height, and the perished surface of equipment is not had repairing effect, be unfavorable for large-scale application.
Summary of the invention:
The purpose of this invention is to provide a kind of aqueous graphite lubricating agent that temperature range is large, cost is low, lubricity is good that is applicable to.
Technical scheme of the present invention is finished as follows, and the composition by weight of this aqueous graphite lubricating agent is: natural or synthetic graphite 10-55 part, rare earth oxide 0.5-1 part, nano level graphite microparticles 0.5-1.5 part, white graphite 1-5 part, molybdenumdisulphide 2-5 part, nanometer three oxidation worker aluminium 1-5 parts, acetone 3-5 part, ethanol 5-10 part, dispersion agent 2-5 part, methylcellulose gum 5-10 part, water glass 5-10 part, distilled water 20-30 part.Rare earth oxide is at least a rare earth oxide of rare-earth elements of lanthanum, cerium, praseodymium.Above-mentioned dispersion agent is by sodium laurylsulfonate and the smooth composite dispersing agent that synthesizes at 1: 1 of pressing of lipid acid sorb.The present invention has cheap, and environmentally safe can be repaired automatically to the equipment perished surface, improves temperature limit and lubricant effect.
Embodiment:
The present invention is described in further detail below in conjunction with embodiment.
Embodiment 1: take by weighing the 10g natural graphite, 1.0g rare earth oxide (La
2O
3), 1.5g nano level graphite microparticles, 5g white graphite, 4g molybdenumdisulphide, the 5g nano-aluminium oxide, 5g acetone, 10g ethanol, 2g dispersion agent (sodium laurylsulfonate 1g, the smooth 1g of lipid acid sorb), 10g methylcellulose gum, 10g water glass, 30g distilled water mixes and namely gets aqueous graphite lubricating agent.
Embodiment 2: take by weighing the 40g natural graphite, 0.5g rare earth oxide (La
2O
3), 0.5g nano level graphite microparticles, 3g white graphite, 4g molybdenumdisulphide, 0.5g nano-aluminium oxide, 3g acetone, 8g ethanol, 3.5g dispersion agent (sodium laurylsulfonate 1.75g, the smooth 1.75g of lipid acid sorb), 8g methylcellulose gum, 5g water glass, 25g distilled water mixes and namely gets aqueous graphite lubricating agent.
Embodiment 2: take by weighing the 55g natural graphite, 1.0g rare earth oxide (La
2O
3), 0.5g nano level graphite microparticles, 4g white graphite, 2g molybdenumdisulphide, 0.5g nano-aluminium oxide, 8g acetone, 5g ethanol, 5g dispersion agent (sodium laurylsulfonate 2.5g, the smooth 2.5g of lipid acid sorb) 20g distilled water mixes and namely gets aqueous graphite lubricating agent.
The lubricant that above embodiment obtains, lubricity is good, simultaneously perished surface is had repairing effect, and is high temperature resistant, anti-oxidant, and slag adhesion is pollution-free.
