Steel wire rope coating

Abstract

The invention discloses a steel wire rope coating. The coating comprises the following components in percentage by weight: 10%-60% of asphalt, 5%-30% of epoxy resin, 4%-15% of cement and 5%-25% of steel wire rope surface grease. The steel wire rope coating coats a steel wire rope, because the steel wire rope coating has good waterproofness and corrosion resistance, seawater can be prevented from corroding steel wires and entering the steel wire rope, and the service life of the steel wire rope is prolonged. In addition, through selection of the model number of the asphalt, the model number of the cement, and the dropping point and kinematic viscosity of the steel wire rope surface grease, the steel wire rope coating is not sticky at a high temperature about 50 DEG C, and does not crack at a low temperature about minus 40 DEG C.

Description

technical field [0001] The invention relates to a steel wire rope coating. Background technique [0002] my country has 32,000 kilometers of coastline, including 18,000 kilometers of mainland coastline and 14,000 kilometers of island coastline. From Fangchenggang in Guangxi in the west to Dandong in Liaoning in the east, the fishery resources are very rich. Ranked first among the world's largest fishery countries, the fishery industry has developed rapidly in recent years. With the country's macro-control of fishery resources, random fishing has been effectively controlled, and the fishery industry has begun to develop into ocean fishing and deep-sea fishing. development of related industries. After inspecting the fishery wire rope market in Guangxi, Guangdong, Fujian, Jiangsu, Shandong, Liaoning and other provinces, there are nearly a thousand fishing boats berthing at the ports and wharves. Only Shenquan Town, Huilai County, Shantou City, Guangdong Province, and Xiangzhi ...

AI Technical Summary

Problems solved by technology

It is estimated that the consumption of fishery wire ropes in the country is more than 80,000 tons. At present, thick galvanized fishery wire ropes are still used more in various fishing ports. Due to the particularity of the environment in which fishery wire ropes are used, the industry has always determined the thickness of the zinc layer (the amount of zinc) and the amount of steel wire ropes. Grease coating is the main target of the technology in order to expect the steel wire rope to have better corrosion resistance. Since the amount of zinc on the steel wire reaches a certain limit, it is more difficult to increase the amount of zinc on the steel wire again. The surface grease on the wire rope , with the prolongation of the use time, it is always lost and volatilized. In fishery production, especially in single-drag and double-drag operations, it is basically impossible to replenish the grease after the wire rope is specially treated. Therefore, many of the above reasons lead to the loss of wire rope short service life

[0003] From the analysis of numerous fishery wire rope damage forms, among them, seawater corrodes the steel wire and enters the inside of the wire rope, causing a considerable proportion of early damage to the wire rope. The overall breakage of the wire rope often brings irreparable economic losses to fishermen. The average fishing economic loss is about 70,000 yuan
