Abstract

The invention discloses a micro-nano fire extinguishing capsule which comprises the following raw materials, by weight, of 10-50 parts of a fire extinguishing agent, 2-5 parts of a coating material, 0.1-1 part of organic silicon oil and 1-5 parts of nano white carbon black. A preparation method includes the steps that (1) the gas fire extinguishing agent and the coating material are uniformly mixed under the pressure of 3 Mpa; (2) the organic silicon oil and the nano white carbon black are added in sequence; and (3) a finished product is obtained after uniform stirring and packaging. According to the micro-nano fire extinguishing capsule, the gas fire extinguishing agent is used as the main material, and by utilizing the characteristic that the microcapsule can stably adsorb other substances and facilitate preservation, the fire extinguishing agent and the microcapsule are fully mixed and other auxiliary materials are added. Storage and transportation of the fire extinguishing agent are achieved, and meanwhile, the advantages of a dry powder fire extinguishing agent and the gas fire extinguishing agent are combined to achieve the purpose of improving the fire extinguishing efficiency.

Description

technical field [0001] The invention relates to a micro-nano capsule fire extinguishing agent, in particular to a micro-nano fire extinguishing capsule and a preparation method for extinguishing electrical fires in the field of coatings and rubber sheets. Background technique [0002] Fire always threatens the safety of life and property of the country and people, and the fire often evolves from a single cause to a complex multi-factor fire due to the different combustibles on site. [0003] Fire extinguishing agent refers to the substance that can effectively destroy the combustion conditions in the combustion zone, so as to resist or stop the combustion. There are many types of fire extinguishing agents, such as water-based fire extinguishing agents, gas fire extinguishing agents, foam fire extinguishing agents, dry powder fire extinguishing agents, etc. [0004] Although the dry powder fire extinguishing agent is low in cost and simple in production process, the dust pol...
