Graphene-plant composite type flame-retardant fire extinguishing agent

Abstract

The invention relates to the field of chemical products and extinguishing agents, in particular to a graphene and plant composite type flame-retardant fire extinguishing agent. The fire extinguishing agent is made of the raw materials such as plant leach liquor, plant ash, graphene, a flame retardant and water, wherein the plant leach liquor is obtained by leaching corn stigmas, cordia dichotoma, Chinese yams, elm bark and pomelo peel. Through tests, the graphene and plant composite type flame-retardant fire extinguishing agent has the excellent flame-retardant fire extinguishing performance and can meet the fire extinguishing requirements of various different environments, in addition, the fire extinguishing agent takes natural components as the raw materials, and therefore environment protection can be realized, no pollutant emission is generated, no damage to the atmosphere, the water quality and the soil can be caused in the using process, the ecological restoration of fire scenes can be facilitated, and adverse effects on survival of human and animals and production of agriculture, forestry, animal husbandry and fishery industry can be avoided.

Description

technical field [0001] The invention relates to the field of chemical products and fire extinguishing agents, in particular to a graphene plant composite flame retardant fire extinguishing agent. Background technique [0002] At present, the traditional fire extinguishing agents widely used at home and abroad, such as: water, foam, dry powder, carbon dioxide, haloalkane, etc., in the fire extinguishing process, use their own properties such as non-combustibility, heat absorption, dilution, etc. Oxygen, terminating substance combustion chain reaction and other effects to achieve the purpose of fire extinguishing. In order to improve the fire extinguishing performance, the traditional fire extinguishing agent will further enhance the heat absorption, burning resistance, film forming, diffusibility and other properties, but the improvement of the fire extinguishing performance by the above means is often very limited. In such a situation, when the temperature of the combustion...

Problems solved by technology

In order to improve the fire extinguishing performance, the traditional fire extinguishing agent will further enhance the heat absorption, burning resistance, film forming, diffusibility and other properties, but the improvement of the fire extinguishing performance by the above means is often very limited. When the temperature of the combustion center is as high as 3000°C and the temperature of the combustion liquid is higher than 400°C, traditional fire extinguishing agents are helpless

[0003] In the early 1980s, researchers began the research on plant-based composite flame retardant fire extinguishing agents. The research goal at that time was purely for the flame retardant and fire extinguishing of automobile fuel tanks. However, the initial test results were not ideal. Until the end of the 1980s, a brand new The plant-type composite flame retardant fire extinguishing agent was first successfully developed in my country and obtained an invention patent. Zhao Guangsheng et al. disclosed a compound fire extinguishing agent composed of Artemisia annua, Artemisia annua, and Ulmus root bark in "Plant Liquid Composite Fire Retardant" (CN88104118.1). The main flame retardant ingredients are the water extracts of plants such as wormwood, mugwort, cabbage, snake vine, cornflower and plant ash, adding anionic, nonionic or zwitterionic surfactants and additives such as triethanolamine and calcium chloride The compounded liquid composite flame retardant has a fast flame retardant and flame extinguishing speed and a wide range of applications, and is especially suitable for fighting fires caused by flammable liquids and oils.

[0006] However, since the application of graphene in the field of fire extinguishing agents is still in the exploratory stage, in addition, considering the particularity of the composition of plant-based composite flame retardant fire extinguishing agents and the limitations of their own production processes, graphene has not yet been used in the production of fire extinguishing agents. There are no similar products available in the relevant research and reports on plant-based composite flame retardant fire extinguishing agents.
