Long acting antirust grease

Abstract

The invention discloses a chemical product, namely long-term antirust grease, which ensures that the production cost is relatively reduced and the antirust time is also prolonged. The effective compositions of the long-term antirust grease comprise machine oil, stearic acid, calcium hydroxide and barium mahogany sulfonate. The operation process of the production technology of the long-term antirust grease is as follows: adding a small amount of machine oil, the stearic acid, the calcium hydroxide and the barium mahogany sulfonate in a reaction kettle first, injecting a certain amount of water, fully saponifying the mixture when the temperature is increased to 130 DEG C, adding remaining machine oil into the reaction kettle, and ensuring that the reaction kettle is subjected to thermal insulation at a temperature of 100 DEG C or so for about 1 hour. The long-term antirust grease can resist from being exposed to the sun and rain; after a metal fastener is coated with the long-term antirust grease, the antirust function is remarkably improved, the antirust performance can reach three years, and the technical problem that the antirust time of old products does not exceed one year is solved; in addition, the long-term antirust grease uses raw materials which are purchased on negotiation, has simple process operation and relatively reduces production cost; and the long-term antirust grease is applicable to the corrosion prevention and lubrication of bolts at various positions such as rail joints, concrete sleepers, railway switches, bridges and so on, and has certain acid, alkali and salt resistance.

Description

technical field [0001] The present invention is a chemical product designed to prevent and prevent corrosion of metal surfaces, especially a product designed to prevent corrosion of fasteners used for laying railway tracks—long-acting antirust grease. Background technique [0002] At present, anti-rust paint, which is widely used in the market for fasteners used in railway track laying, is widely used due to its formula composition and process conditions, but its cost is high and its anti-rust performance is not very good. Stable, generally slaughtered fasteners can only be kept for one year, and rust spots will appear on the fasteners after one year. For this situation, researchers in the industry have been engaged in research and want to extend the anti-rust time, but they have not been able to solve it. Contents of the invention [0003] For the above technical defects that exist, the object of the invention is to: propose a kind of long-acting anti-rust grease that no...
