Abstract

The invention discloses a compound corrosion inhibitor for a chlorine salt-type snow-melting agent and an application of the compound corrosion inhibitor. The compound corrosion inhibitor comprises the following materials in parts by mass: 12-35 parts of sodium hexametaphosphate, 8-20 parts of sodium silicate, 5-20 parts of zinc dihydrogen phosphate, 5-12 parts of sodium dodecyl benzene sulfonate, 5-20 parts of sodium tartrate, 4-12 parts of hexamethylene tetramine, and 6-13 parts of allyl thiourea, wherein the compound corrosion inhibitor is obtained by uniformly mixing the materials in the proportioning ratio. The prepared compound corrosion inhibitor can be bagged and sold by being uniformly mixed with chlorine salt in a ratio of (0.5 to 8): 100 of parts by mass. The compound corrosion inhibitor disclosed by the invention is a special corrosion inhibitor aiming at the chlorine salt-type snow-melting agent, has an obvious slow-release effect on the metals, such as roads, bridges and ancillary facilities and then achieves a good slow-release effect via the co-action of the seven materials.

Description

technical field [0001] The invention relates to a compound corrosion inhibitor of chlorine salt type deicing agent and its application. Background technique [0002] Snow in winter is the "enemy" of my country's transportation, seriously affecting road safety and smooth transportation, so people study the technology of road deicing and snow melting. Among them, the use of deicing agent is the most widely used method. The deicing agent is mainly used in airports, highways, railways, urban streets and other places to remove ice and melt snow. There are many types of deicing agents, mainly chlorine salt type and non-chlorine salt type. Due to the high cost, non-chlorine salt deicing agents are less used now. Chloride deicing agents have been widely used in road deicing and deicing because of their good deicing effect and low price. So far, chlorine salt deicing agents are still the main body. Sodium chloride was mostly used in the early days, and calcium chloride, magnesiu...
