Abstract

The invention relates to the technical field of chemical engineering materials, and specifically relates to a molecular expansion-solidification agent. The agent comprises the following components, by weight: 5-10% of olyethylene glycol with molecular weight of 50-2000, 50-70% of water, 12-22% of 4.4-diphenylmethane isocyanate, and 15-30% of dibutyltin dilaurate. The invention aims at providing the molecular expansion-solidification agent with the advantages of fast expansion and solidification, and high-pressure resistance.

Description

technical field [0001] The invention relates to the technical field of chemical materials, in particular to a molecular expansion agent. Background technique [0002] my country is not only a major producer of coal, but also a country with a large demand for coal. However, the situation in mines is very complicated, and there may be fires, leakage of harmful gases, and fractures in rock mass roadways. Therefore, molecular expansion agents are essential for mines. Molecular expansion agents currently on the market usually include two types, one is polyurethane monomers, and the other is a compound of polyols, catalysts, fillers and other substances. Compared with the two, the two-component has a longer storage period than the single-component, and the storage is relatively convenient. But these two kinds of molecular expansion agents all have the shortcoming that the time required for expansion is long. Contents of the invention [0003] The purpose of the present inven...
