Abstract

The invention relates to a low-temperature non-adhesive petrolatum anticorrosion paste which is characterized by containing the following components in percentage by mass: 36-42% of beta-hydroxyalkyl primary amide polyester resin, 1.4-1.6% of bisphenol A epoxy resin, 22-28% of paraffin, 3-5% of organobentonite, 5-8% of composite filler, 5-8% of barium petroleum sulfonate, 0.1-1% of chopped fiber, 6-8% of lanolin, 8-12% of aluminum stearate and 7-8.1% of curing agent. The low-temperature non-adhesive petrolatum anticorrosion paste can be quickly solidified in a high-cold low-temperature environment to form a continuous organic cover layer. The cover layer can not easily crack in the low-temperature environment, and has favorable corrosion resistance. The low-temperature non-adhesive petrolatum anticorrosion paste is convenient for construction, has favorable adhesive force, has the physical isolation protective action, and can perform the function of favorable corrosion protection for bolt fasteners. The low-temperature non-adhesive petrolatum anticorrosion paste can resist rain and snow at low temperature, does not shed or crack, and facilitates the construction and later maintenance operation.

Description

technical field [0001] The invention relates to the technical field of petrolatum anti-corrosion paste, in particular to a low-temperature anti-corrosion anti-corrosion paste used for bolt fasteners of power grid transmission line pole towers and gaps between steel frame structures and bolt fasteners in high-cold and low-temperature environments. Use non-stick petrolatum anti-corrosion paste. Background technique [0002] At present, most of the transmission line poles and towers in the domestic power grid adopt the protection measures of hot-dip galvanizing and anti-corrosion coating. The cathodic protection effect of the hot-dip galvanizing layer is relatively good in areas with good environmental conditions. However, in the high cold and low temperature environment, most of them have been operated for a certain period of time. As the hot-dip galvanized coating gradually corrodes, its protective effect on the carbon steel structure of bolt fasteners gradually decreases unt...
