Abstract

The present invention belongs to the field of compounded salt technology. It is made up by respectively adding at least three kinds of chemical raw materials of chlorinated trisodium phosphate, calcium hypochlorite or high test bleaching powder, aluminium chloride or aluminium polychloride, lithium hypochlorite, sodium sulfate peroxide, sodium metasilicate, sodium molybdate, sodium benzoate, trisodium phosphate, sodium tetraborate of medicinal borax and benzotriazole, etc into the formula composition formed from water and calcium chloride through a certain proportion process. Said invention has two kinds of solid product and liquid product, and can be used when the temperature is above-43 deg.C, its ice-melting and snow-removing speed is quick and its effect is good.

Description

[0001] A quick-melting agent for ice and snow, which has obvious ice-melting and snow-removing effect, a wide range of applications, a simple preparation method, and meets environmental protection requirements. [0002] 1. Technical field: It belongs to the field of chemistry and is the field of composite salt technology. 2. Background technology [0003] 1. Understanding of the invention of "a fast melting agent for ice and snow" [0004] An ice-snow quick-melting agent and the currently used deicing agent, whether in solid or liquid state, are used to reduce the freezing point of water. Its working mechanism belongs to the category of surface chemistry and belongs to the field of composite salt technology. It uses the water absorption of an ice and snow quick-melting agent and a large amount of heat when it melts, dislocation of the structural lattice in the snow, causing the ice and snow to melt; when the ice and snow melt, heat is absorbed and the surrounding temperature drops....
