Embodiment 1

[0012] Embodiment 1: (1) first mix the magnesium hydroxide of 52 parts, the aluminum hydroxide of 32 parts uniformly in stirring equipment, turn on heating, add the surfactant of 0.4 part, the mica powder of 5 parts, the mica powder of 6 parts successively in proportion Mix 1 part of talcum powder and 2 parts of ceramsite under continuous stirring to obtain intermediate product A at a temperature of 60-70°C; (2) Dissolve 0.2 parts of hydrogen-containing silicone oil in the stabilizer and stir Add a certain amount of foaming agent to obtain the intermediate product B; (3) Mix A and B uniformly at 100-120°C in the stirring equipment. After the stabilizer and foaming agent are partially volatilized, add 4 parts of white carbon black and mix Stir well to get the final product.

Embodiment 2

[0013] Embodiment 2: (1) first mix 46 parts of magnesium hydroxide and 38 parts of aluminum hydroxide in a stirring device, turn on the heating, and add 0.5 parts of surfactant, 4 parts of mica powder, 7 parts in proportion Mix 1 part of talcum powder and 2 parts of ceramsite under continuous stirring to obtain intermediate product A at a temperature of 60-70°C; (2) Dissolve 0.2 parts of hydrogen-containing silicone oil in the stabilizer and stir Add a certain amount of foaming agent to obtain the intermediate product B; (3) Mix A and B uniformly at 100-120°C in the stirring equipment, and after the stabilizer and foaming agent volatilize, add 3 parts of white carbon black and mix Stir well to get the final product.

Embodiment 3

[0014] Embodiment 3: (1) first mix 40 parts of magnesium hydroxide and 50 parts of aluminum hydroxide in a stirring device, turn on the heating, and add 0.5 parts of surfactant, 2 parts of mica powder, 5 parts in proportion Mix 1 part of talcum powder and 2 parts of ceramsite under continuous stirring to obtain intermediate product A at a temperature of 60-70°C; (2) Dissolve 0.2 parts of hydrogen-containing silicone oil in the stabilizer and stir Add a certain amount of foaming agent to obtain the intermediate product B; (3) Mix A and B uniformly at 100-120°C in the stirring equipment, and after the stabilizer and foaming agent volatilize, add 2 parts of white carbon black and mix Stir well to get the final product.

Abstract

The invention discloses a ceramsite dry powder extinguishing agent, which comprises the following raw material components in percentage by mass: 0.1-0.8% of a surfactant, 3-12% of mica powder, 5-8% oftalcum powder, 2-5% of ceramsite, 40-55% of magnesium hydroxide, 30-40% of aluminum hydroxide, 0.15-1.2% of hydrogen-containing silicone oil, 0.15-0.25% of a foaming agent, 0.3-0.5% of a stabilizer and 2-6% of white carbon black. According to the invention, the product is low in cost, the problem of high cost of superfine dry powder extinguishing agents in the prior art is solved, and magnesium hydroxide and aluminum hydroxide used in the invention are easy to realize, have wide sources, belong to non-toxic and environment-friendly efficient flame retardants, and have high fire extinguishingperformance after being used together.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing agents, in particular to a ceramsite dry powder fire extinguishing agent. Background technique [0002] Traditional dry powder fire extinguishing agents have the characteristics of being suitable for a wide range of fire types, low environmental toxicity, and suitable for water-scarce areas. However, due to the large particle size of most dry powder powders, poor particle dispersibility, and relatively small specific surface area, it causes its capture The ability of Baiyouji is small, so the fire extinguishing ability is limited, which limits the application range of dry powder fire extinguishing agent to a certain extent. Moreover, traditional dry powder fire extinguishing agents usually use inorganic salts as base materials, such as sodium bicarbonate, ammonium phosphate and amino dry powder. Due to the poor fire extinguishing ability of sodium bicarbonate dry powder fire extinguish...
