Long-acting inhibitor capable of continuously generating inhibition and inerting effects and preparation method of long-acting inhibitor

Abstract

The invention discloses a long-acting inhibitor capable of continuously generating inhibition and inerting effects, belongs to the technical field of fire prevention and extinguishing of inhibitors, and can solve the problems that an existing inhibitor is low in inhibition efficiency, short in inhibition period and unstable in inhibition effect. The 2, 2, 6, 6-tetramethylpiperidine oxide is coated with amino silicon oil to prepare the inhibition balls, the inhibition balls are embedded into sodium alginate gel, controlled release of the 2, 2, 6, 6-tetramethylpiperidine oxide can be achieved, CO2 generated by decomposition of sodium bicarbonate and O2 form competitive adsorption, the effect of inerting spontaneous combustion of coal is achieved, O2 can be well isolated through the alginic acid gel layer on the outer layer, and the spontaneous combustion effect of coal is improved. The effect of multiple inhibition of coal spontaneous combustion is achieved, the inhibition effect on coal spontaneous combustion is greatly improved, and the utilization rate of the inhibitor is effectively increased.

Description

technical field [0001] The invention belongs to the technical field of fire prevention and extinguishing by an inhibitor, and in particular relates to a long-acting inhibitor capable of continuously producing an inhibitory inerting effect and a preparation method thereof, and has multiple inhibitory effects. Background technique [0002] Coal is an important part of my country's energy, accounting for more than half of my country's energy consumption for a long time. However, coal always faces the danger of spontaneous combustion in the process of mining, transportation and storage. At the same time, the spontaneous combustion of coal left in the goaf also threatens the safe production of coal mines. At present, chemical inhibitors are one of the important technical means to prevent and control mine fires. [0003] At this stage, there are many kinds of inhibitors, which can be roughly divided into physical inhibitors, chemical inhibitors and composite inhibitors according ...

AI Technical Summary

Problems solved by technology

However, catechins, vitamin C, etc. are easily oxidized and "deteriorated" in the air. In the early stage of coal spontaneous combustion, they are consumed in vain by the oxygen flowing in the air, so that they can't play a good role in the inhibition effect, and the inhibition life is very short. limited

Therefore, some scholars wrap vitamin C or catechin in cages to reduce their useless consumption, so as to play a slow-release role. However, the inhibitor components in the coat must reach the temperature at which the aftercoat breaks to release, which will have a negative effect on the body. The inhibitory effect has a certain influence
