Abstract

The invention discloses a preparation method and a release method for a composite inhibition substance with oxidation and self-heating temperature-control secundine, and belongs to the preparation method and the release method of the composite inhibition substance. Water is taken as a solvent, and a composite inhibition substance particle with high water content comprises an inorganic inhibitor, a functional ionic liquid, a flame retardant, an activator and a curing material; temperature-control inhibition substance secundine comprises a composite high polymer oxidation and self-heating material. The composite inhibition substance particle having high water content and containing the oxidation and self-heating temperature-control secundine is dispersed to a mining region; when the mining region is spontaneously heated to a temperature 55 DEG C or less, the composite inhibition substance with high water content is in a good packaging state; when the mining region is spontaneously heated to a temperature of 55-65 DEG C, most temperature-control secundine made of the composite high polymer oxidation and self-heating material is automatically degraded and cracked, so that the composite inhibition substance with high water content inside is released to prevent residual coals in the mining region from spontaneous combustion. The composite inhibition substance with oxidation and self-heating temperature-control secundine has the advantages of good dispersion, strong stability, long inhibition function retaining time and small coal bed inclined angle interference and is capable of automatically degrading, cracking and releasing the inhibitor after spontaneously raising the temperature to a certain temperature.

Description

technical field [0001] The invention relates to a method for preparing and releasing a composite inhibitor, in particular to a method for preparing and releasing a composite inhibitor containing an oxidized self-heating temperature-controlled cell coat. Background technique [0002] my country is not only the country with the largest coal production in the world, but also one of the countries with the most serious spontaneous combustion of coal seams. Every year, the number of coal mine deaths in my country is 200 times that of the United States, more than 10 times that of India, and the death rate per million tons is 10 times that of the world average. According to statistics, mines with spontaneous combustion hazard account for about 51.3% of the key state-owned coal mines in my country, accounting for more than 90% of the total mine fires. Therefore, coal spontaneous combustion in goafs not only poses a major threat to the lives of miners and national property, but also ...
