A kind of low-chloride salt and chlorine-free salt environmental protection ice melting material based on attachment carrier and preparation method thereof

Abstract

The invention relates to a low-chloride salt and a chlorine-free salt environment-friendly ice-melting material based on an attachment carrier and a preparation method thereof, and belongs to the technical field of highway engineering in transportation engineering. The environmentally friendly ice-melting material includes an attachment material, an ice-melting agent, a hydrophobic material and water; the attachment material is a mixture of pozzolan and pine bark powder, or a mixture of bagasse and pozzolan; the ice-melting agent is powdered industrial salt or calcium acetate; hydrophobic The material is nano-silica. The ice and snow melting material of the invention can reduce the corrosion and damage to the highway structure facilities and the surrounding environment, reduce the application cost of the environment-friendly ice melting agent without chlorine salt to the greatest extent, and effectively solve the practical problem of snow freezing on the road area in winter. .

Description

technical field [0001] The invention belongs to the technical field of highway engineering in transportation engineering, and in particular relates to a low-chlorine salt and non-chlorine salt environment-friendly ice-melting material based on an attachment carrier and a preparation method thereof. Background technique [0002] According to incomplete statistics, at this stage, more than 90% of the ice and snow melting materials used for deicing and snow removal on highway roads are chloride salts. Ancillary facilities such as guardrails cause greater corrosion and cause greater damage to the soil along the line, and the chlorine-free salt-free environmentally friendly ice-melting agent for road snow and icing is expensive, about 20 times that of ordinary chlorine-salt ice-melting agents. , which restricts the large-scale use of chlorine-free environmentally friendly ice-melting agents. [0003] In view of the demand for melting ice and snow under low temperature and snow c...

Problems solved by technology

[0002] According to incomplete statistics, more than 90% of the ice and snow melting materials used for deicing and snow removal on highway pavement at this stage are chlorine salts. Only based on experience, the average spraying amount is mostly 200-500g / ㎡ each time. Ancillary facilities such as guardrails cause greater corrosion and greater damage to the soil along the road. The chlorine-free salt-based environmentally friendly deicing agent for snow and ice on the road is expensive, which is about 20 times that of ordinary chloride-salt deicing agents. , restricting the large-scale use of chlorine-free salt-free environmentally friendly deicing agents

[0003] In response to the demand for ice and snow melting under low temperature and ice and snow conditions in winter, as well as the excessive spraying of chlorine salt for melting ice and snow in winter maintenance operations of traditional roads, the environmental pollution and infrastructure corrosion damage caused by the extensive use of industrial salt, coupled with the current chlorine-free salt Due to the high price of environmentally friendly deicing agents, there is an urgent need to carry out research on new materials for road surface melting and deicing, so as to reduce the amount of chloride salt used in road surface deicing and snow removal, protect road surface structure facilities and ecological environment, and reduce road surface melting. The cost of ice agent, in order to facilitate the popularization and application
