specific Embodiment 1

[0019] Phosphate flame retardant solution is mixed with ammonium dihydrogen phosphate and diammonium hydrogen phosphate at a molar ratio of 8:2, fully dissolved in deionized water, and water-soluble high temperature resistant phenolic resin is mixed with deionized water at a ratio of 5:10 , Prepare the solution in the above proportion, then add 5 parts of silica airgel and 2 parts of adhesion promoter in the same proportion, and finally add 3 parts of chemical foaming agent and 3 stirring beads in the same proportion. Mix according to the above ratio, stir in the container for 60 minutes to fully mix the components, then add foaming agent, pour the solution into the tank, and put 3 stirring beads.

specific Embodiment 2

[0021] Phosphate flame retardant liquid is mixed with ammonium dihydrogen phosphate and diammonium hydrogen phosphate at a molar ratio of 7:3, fully dissolved in deionized water, and water-soluble high temperature resistant phenolic resin is mixed with deionized water at a ratio of 3:10 , Prepare the solution in the above proportion, then add 4 parts of silica airgel and 2 parts of adhesion promoter in the same proportion, and finally add 4 parts of chemical foaming agent and 3 stirring beads in the same proportion. Mix according to the above ratio, stir in the container for 60 minutes to fully mix the components, then add foaming agent, pour the solution into the tank, and put 4 stirring beads.

specific Embodiment 3

[0023] Phosphate flame retardant solution is mixed with ammonium dihydrogen phosphate and diammonium hydrogen phosphate at a molar ratio of 9:1, fully dissolved in deionized water, and water-soluble high temperature resistant phenolic resin is mixed with deionized water at a ratio of 4:10 , Prepare the solution in the above ratio, then add 3 parts of silica airgel and 2 parts of adhesion promoter in the same ratio, and finally add 5 parts of chemical foaming agent and 3 stirring beads in the same ratio. Mix according to the above ratio, stir in the container for 60 minutes to fully mix the components, then add foaming agent, pour the solution into the tank, and put 5 stirring beads.

Abstract

The invention discloses a preparation method for a fire-retardant heat-insulating foam spray used for fire emergency escape, and relates to a preparation method for a flame-retardant spray. The preparation method for the spray comprises the following process: mixing ammonium biphosphate and diammonium phosphate and then fully dissolving the formed mixture in deionized water to prepare a phosphatic fire-retardant fluid; mixing water-soluble high-temperature-resistant phenolic resin with deionized water, and preparing a solution according to a certain ratio; then adding silica aerogel and an adhesion promoter; finally adding a chemical foaming agent and stirring beads and carrying out mixing according to a certain ratio; performing stirring in a container to allow all the components to be thoroughly mixed; and then adding a foaming agent, injecting the formed solution into a tank, and adding the stirring beads. The foam spray prepared through the synergistic action of the above components can be quickly sprayed onto the surfaces of human bodies, clothes, daily necessities and the like, and generated foam provides heat insulation effect, thereby helping a trapped person to safely and quickly escape from a fire scene, reducing the damage of the fire to the human body and ensuring life safety.

Description

technical field [0001] The invention relates to a method for preparing a flame-retardant spray, in particular to a method for preparing a flame-retardant and heat-insulating foam spray for fire emergency escape. Background technique [0002] A sudden fire will bring us serious personal injury and huge economic loss. At present, the main advantage of the fire-fighting facilities equipped in public places is to extinguish the flames within the controllable range, but their emergency escape effect is not ideal when the fire is out of control. Therefore, a portable fire escape spray product that can be sprayed on the surface of clothing to form a flame-retardant and heat-insulating layer is developed to protect the human body from being burned or reduce burn damage during the process of rushing through the fire scene, thereby greatly increasing the number of people in the fire. It has important practical significance to improve the escape efficiency and greatly reduce the casua...
