Abstract

The invention discloses a TDI macromolecular gel decontaminating agent. The decontaminating agent is prepared from the following components in parts by weight: 35 to 45 parts of toluene diisocyanate,45 to 55 parts of polyether amine D230 and 10 to 20 parts of isopropanol. According to the invention, the isopropanol can reduce the viscosity of other components and is convenient to disperse, the polyether amine D230 and the toluene diisocyanate are subjected to a chemical reaction, a macromolecular substance generated by the reaction is a gel, and a gel skeleton can be generated under the action of chemical bonds to wrap toluene. The product disclosed by the invention is high in reaction speed, and a curing effect can be achieved within 2 minutes; the dosage of the decontaminating agent issmall, the decontaminating agent can be cured when the content of the decontaminating agent is about 5%, and various parameters of a decontaminating product are optimal when the content is 15%; the decontamination product is convenient for subsequent treatment and can be quickly recycled.

Description

technical field

[0001] The invention belongs to the technical field of post-disposal treatment of dangerous chemical goods, and in particular relates to a TDI macromolecular gel decontaminant. Background technique

[0002] With the rapid development of my country's modern industry, toluene is an important chemical raw material, and leakage accidents occur frequently due to various reasons. Toluene has the characteristics of flowing and volatilizing rapidly, burning and exploding when exposed to heat or open flame, and having a great poisonous effect on the surrounding environment and human body. The characteristic is that once such hazardous chemicals leak, if the situation cannot be controlled in a short time to curb the development, it will cause pollution of the surrounding soil and water bodies at the slightest, and cause casualties or even cause serious consequences such as fire and explosion. In dealing with such leakage accidents of hazardous chemicals, the emergency r...
