preparation example Construction

[0052] In order to achieve the above purpose, the present invention also proposes a preparation method of the microcapsule fire extinguishing material. The method is applied to the above-mentioned microcapsule fire extinguishing material, and the method comprises the following steps:

[0053] S1, adding clear water to the water phase substance, stirring until completely mixed to obtain the first mixed solution;

[0054] S2, adding the oil phase substance to dodecafluoro-2-methyl-3-pentanone or its homologue, and stirring until completely mixed to obtain a second mixed solution;

[0055] S3, adding the first mixed solution obtained in step S1 to the second mixed solution obtained in step S3, and stirring to obtain a microcapsule fire extinguishing material.

[0056] Wherein, in step S1, the stirring speed is 15000-25000r / min, such as 15000r / min, 20000r / min, or 25000r / min; the stirring time is 5-10min, such as 5min, or 7.5min, or 10min.

[0057] In step S2, the stirring speed ...

Embodiment approach

[0060] As an implementation manner, after the step S3, it also includes:

[0061] Step S4, attaching a double-sided adhesive foam substrate with a thickness of 1 to 2 mm on the capsule wall;

[0062] Step S6, sticking non-woven fabric or kraft paper on the double-sided adhesive tape.

[0063] In the present invention, the microcapsule coating material is made of synthetic polymer material mixed material, which has certain strength and rigidity, plays the role of structural support and provides a loading space for the fire extinguishing medium. The present invention can be mainly used in the space where electric cabinets, switch boxes, etc. are installed in electric equipment, and can also be used in various closed or relatively closed environments, and has wide applicability.

[0064] The capsule core used in the present invention is difluoro-2-methyl-3-pentanone or its homologues with high-efficiency fire extinguishing properties, and the method for preparing microcapsules t...

Embodiment 1

[0067] In this example, based on the total mass of the components of the microcapsule fire extinguishing material as 100 g, dodecafluoro-2-methyl-3-pentanone: 80 g; ethylene glycol: 10 g; benzenetricarboxylic acid chloride: 10 g.

[0068] It should be noted that, in the process of preparing the microcapsule fire extinguishing material using the preparation method of the microcapsule fire extinguishing material of the present invention, 60 g of water needs to be added. The preparation method of the microcapsule fire extinguishing material proposed in this embodiment includes the following steps:

[0069] Weigh 80 g of dodecafluoro-2-methyl-3-pentanone, 10 g of ethylene glycol, 10 g of trimellitic acid chloride, and 60 g of clear water. Mix ethylene glycol and water evenly, trimelliticoyl chloride and dodecafluoro-2-methyl-3-pentanone evenly. Pour the aqueous solution of ethylene glycol into another mixture evenly. The temperature is controlled between 20°C and 40°C, and the re...

Abstract

The invention discloses a microcapsule fire extinguishing material and a preparation method thereof. The microcapsule fire extinguishing material comprises a capsule wall and a capsule core fire-extinguishing medium coated by the capsule wall, the capsule wall is formed by polymerizing a water phase medium and an oil phase medium, and the microcapsule fire extinguishing material comprises the following components in percentage by mass: 70%-90% of capsule core fire-extinguishing medium, 5%-15% of water phase medium and 5%-15% of oil phase medium, wherein the capsule core fire-extinguishing medium is dodecafluoro-2-methyl-3-pentanone or a homologue of dodecafluoro-2-methyl-3-pentanone, the water phase medium is polyol or polyamine, and the oil phase medium is polyacyl chloride. Compared withthe prior art, the material is simple and easy to install, detection starting is accurate and reliable, fire extinguishing is fast and fire extinguishing efficiency is high.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing agents for fire engineering, in particular to a microcapsule fire extinguishing material and a preparation method thereof. Background technique [0002] Fire is one of the disasters in people's daily life. In order to prevent fire, people have taken various positive measures. Among them, the first problem to be solved in suppressing disasters is to develop a fire extinguishing device with superior performance. Fire extinguishing devices can be divided into gas, liquid, and solid according to the type of fire extinguishing materials. Among them, the gas type is mainly heptafluoropropane, aerosol, IG541, carbon dioxide; the liquid type is mainly water, modified water-based and foam fire extinguishing materials; the solid type is mainly For dry powder. The above-mentioned fire extinguishing devices must adopt a relatively complex structure, and need to cooperate with the control and star...
