Problems solved by technology

[0007] Chloride-salt type deicing agents in the prior art, although corrosion inhibitors are also added, have low corrosion inhibition effect and are corrosive to carbon steel
Failure to take into account the impact of deicing agents on vegetation, long-term use, the accumulation of deicing agents to a certain extent will cause the death of vegetation
Corrosion to the concrete structure will reduce the strength of the concrete and the concrete will fall off

Abstract

The invention provides a plant-based high-efficiency corrosion-inhibiting composite snow-melting agent, which is made of the following raw materials in mass percentage: 95-98% of a chloride salt composition and 2-5% of a corrosion inhibitor; the chloride salt composition is composed of chlorine Two or three of sodium chloride, calcium chloride dihydrate and magnesium chloride hexahydrate; the corrosion inhibitor is composed of kelp, sodium molybdate, sodium gluconate, sodium tartrate, zinc sulfate and potassium dihydrogen phosphate. The snow-melting agent of the invention has strong snow-melting ability, little damage to metal and concrete corrosion and vegetation, the corrosion inhibitor is mainly plant, non-toxic, and is a very efficient and environment-friendly compound snow-melting agent. The invention also provides a preparation method and a use method of the plant-based high-efficiency corrosion-inhibiting composite deicing agent.

Description

technical field [0001] The invention belongs to the field of environmental technology, and in particular relates to a plant-based high-efficiency corrosion-inhibiting composite deicing agent and its preparation method and application method. Background technique [0002] In snow disasters or freezing areas, roads, airport pavements, and bridge decks often experience snow and ice, which seriously hinders traffic, people's normal life, and economic development. At the same time, the incidence of vehicle accidents in special areas such as large longitudinal slopes, bridge deck ramps, and turns is also on the rise. According to the "National Road Traffic Accident Statistics Annual Report White Paper", 30% of traffic accidents are caused by bad weather. According to long-term observation and statistics by Kuemmel and others from Marquette University, effective road snow melting and ice melting measures can reduce the incidence of traffic accidents in winter by about 88.3%, and th...
