Problems solved by technology

[0004] Existing anti-fire extinguishing chemical inhibitors have the following deficiencies: 1. Existing anti-fire extinguishing chemical inhibitors appear in solid form and are affected by the solubility of their materials. Its solubility will change; when it is dissolved in water according to the inherent dissolution ratio during use, the dissolution rate will slow down and crystals will precipitate out
2. High corrosiveness. Most of the existing inhibitors use magnesium chloride as the main material. The dissolved solution of this inhibitor is very corrosive; it will cause great damage to equipment and personnel in the use environment
3. The inhibition time is short. After the existing inhibitors are sprayed, the inhibition time is less than 200min under the experimental conditions.

Abstract

The invention discloses a liquid-state composite fire preventing and extinguishing retardant and a preparation technique thereof, relating to the technical field of retardants. According to a formula, the liquid-state composite fire preventing and extinguishing retardant comprises the following components in percentage by weight: 10%-20% of magnesium hydroxide, 5%-10% of aluminum hydroxide, 3%-5% of sodium percarbonate, 7%-10% of sodium bicarbonate and 2%-5% of magnesium chloride. The preparation technique comprises the following steps of adding the components into 37%-66% of water, stirring, adding a penetrating agent, a suspending agent, a stabilizing agent, a preservative, a water-retaining agent, an adsorbing agent and a foaming agent into the obtained mixed liquid, and filtering, cooling, stirring and standing, so as to prepare transparent mixed liquid, namely the liquid-state composite fire preventing and extinguishing retardant. The liquid-state composite fire preventing and extinguishing retardant has the beneficial effects that the retardant rate is increased, and the retardant further has effects of environmental protection, disinfection, corrosion prevention and sterilization; by adding the water-retaining agent, the water solubility of the retardant is improved, so that after the retardant penetrates into a coal body, the wettability of the coal body is increased, dust on a coal mining face is greatly reduced, the production safety factor is increased, the underground working environment is improved, and the environment is protected.

Description

【Technical field】 [0001] The invention relates to a chemical inhibitor and a preparation process, more specifically, the invention relates to a liquid compound fire-preventing chemical inhibitor and a production process thereof. 【Background technique】 [0002] Inhibitor is actually a kind of catalyst, such as graphite in nuclear reaction. When the action of the catalyst slows down the reaction rate, it is called negative catalyst or inhibitor. Usually, because the positive catalyst is used more often, unless otherwise specified, the catalyst refers to the positive catalyst and does not refer to the inhibitor. [0003] In chemistry, all substances that can reduce the speed of chemical reactions are called inhibitors. Its mechanism of action is: 1) increase the chemical inertness of coal at low temperature, or increase the energy of coal oxidation; 2) form a liquid film to surround the surface cracks of coal and coal; 3) fill the internal cracks of coal pillars; 4) increase ...
