Abstract

A protective grease for the T-shaped screw bolt of railway is proportionally prepared from fatty acid lithium soap, lanolin magnesium soap, barium dinonyl naphthalenesulfonate, enylbutanedioic acid, silican oil, phenyl-alpha-naphthaleneamine, and synthetic alkylbenzene oil. Its advantages are high anticorrosion, antirust, antiageing and water-proof effect and high adhesion.

Description

1. Technical field [0001] The invention relates to a special protective grease for anti-corrosion and anti-rust of T-shaped bolts of railway rails. 2. Background technology [0002] The maintenance of railway turnouts is a matter of great concern to the railway engineering department. The failure of sleeper plastic casings and the corrosion of T-bolts are common, which will cause problems in the fastening of the rails, which will cause changes in the gauge and direction of the turnouts. It will have an adverse effect on the ride comfort of the train and directly affect the safety of train operation. Therefore make a kind of protective article that can not only make bolt anti-corrosion and anti-rust but also make plastic bushing not aging for a long time, become a problem demanding prompt solution. 3. Contents of the invention [0003] The purpose of the invention is to make a special protective grease suitable for long-term anticorrosion and antirust of T-type railway tur...
