Benefits of technology

This patented technology describes an improved fire extinguishable liquid called mini encaplets (microencapsulated liquids). These tiny particles contain chemical agents like fluorochloronitrogen compounds, nitrous oxide, carbon dioxide, hydrocarbons, organic solvents, plasticizers, lubricants, water, and dyes. Unlike traditional flame retardant products, these mini encapsulate solutions provide effective protection against fires without causing harmful side reactions. Additionally, they may include other components besides those mentioned above. Overall, this new solution offers superior performance over existing ones while reducing costs compared to current methods.

Problems solved by technology

This patented technical problem addressed by the present inventors relates to finding ways for making better use of these materials while maintain their effectiveness during fires or other situations where they could be harmful if used alone without being activate properly.

Embodiment 1

[0030] Melamine: formaldehyde = 1:1 mass ratio is used as a wall material, heated and dissolved in an appropriate amount of water, adjusted to PH = 8-9 with 5% sodium hydroxide, and reacted in a 70-degree water bath for 1 hour to obtain viscous and translucent melamine-formaldehyde prepolymerization Body solution, with perfluorohexanone having a mass ratio of 1:2 to melamine as the core material, and an appropriate amount of distilled water in the presence of emulsifier styrene maleic anhydride copolymer at high speed for 10 minutes and then adding to the melamine formaldehyde prepolymer solution , add dilute hydrochloric acid to slowly adjust the pH between 2-4, slowly raise the temperature to 60 degrees to carry out microencapsulation reaction for 4 hours, adjust to neutrality and centrifuge to obtain microcapsules. Add the prepared microcapsules to a certain amount of epoxy resin and glass fiber and stir evenly to prepare the fire extinguishing composition.

Embodiment 2

[0032] Urea: formaldehyde = 1:1.5 mass ratio as a wall material, heated and dissolved in an appropriate amount of water, adjusted to PH = 8.5-9.5 with triethanolamine, and reacted in a 70-degree water bath for 1.5 hours to obtain a viscous and translucent urea-formaldehyde prepolymer solution. Perfluorooctane with a mass ratio of urea of ​​1:2 is used as the core material, and an appropriate amount of distilled water is homogenized at high speed for 10 minutes in the presence of the emulsifier sodium lauryl sulfate, then added to the urea-formaldehyde prepolymer solution, and 10% dilute The hydrochloric acid slowly adjusts the pH between 2-4, slowly raises the temperature to 60°C for microencapsulation reaction for 4 hours, adjusts to neutral, and centrifuges to obtain microcapsules. The prepared microcapsules are added to a certain amount of gelatin solution and aluminum hydroxide and stirred evenly to obtain the fire extinguishing composition

Embodiment 3

[0034] Use melamine: urea: formaldehyde with a mass ratio of 1:1:1 as the wall material, heat and dissolve with an appropriate amount of distilled water, adjust the pH to 8.5 with triethanolamine, and react in a 70-degree water bath for 1.5 hours to obtain viscous and translucent melamine urea-formaldehyde prepolymerization Body solution, tetrafluorodibromoethane with a mass ratio of melamine of 1:3 is used as a core material, and an appropriate amount of distilled water is added to the melamine urea-formaldehyde prepolymer solution after high-speed homogenization in the presence of emulsifier Tween 80 for 10 minutes. Add ammonium chloride solution to slowly adjust the pH to 3.5, slowly raise the temperature to 70°C for microencapsulation reaction for 4 hours, adjust to neutral, and centrifuge to obtain microcapsules. The prepared microcapsules are added into a certain amount of silicon rubber and silicon dioxide micropowder and stirred uniformly to prepare the fire extinguishi...

Abstract

The invention relates to a microcapsule automatic fire extinguishing agent. The microcapsule automatic fire extinguishing agent is characterized in that the fire extinguishing agent comprises a main fire extinguishing material, a microcapsule clad material and an auxiliary material; the main fire extinguishing material is wrapped with the clad material to form a microcapsule, and the particle sizeof the microcapsule is 5-150 [mu]m; and the clad material is a resin shell formed by reacting melamine and/or urea formaldehyde with formaldehyde. The microcapsule automatic fire extinguishing agentis a fire extinguishing composition which is simple, low in cost and high in reliability, and after the microcapsule automatic fire extinguishing agent is made into a product, no power source, no special smoke/temperature detector, no complex apparatus and no pipeline are needed. The microcapsule automatic fire extinguishing agent integrates detecting, controlling, starting and fire extinguishingunits into a whole and is simple in structure, small in occupied space, safe and quick in fire extinguishing and low in maintaining cost.
