Description

A kind of small particle ABC powder extinguishing agent and preparation method thereof

Technical field

The present invention relates to powder extinguishing agent technical field, more particularly to a kind of small particle ABC powder extinguishing agent and its preparation Method.

Background technology

It is bromine fluorine hydrocarbons to breathe out imperial 1211 extinguishing chemicals, finds there be huge break to atmospheric ozone layer through American scientist research Bad effect, is an important factor for causing Ozone hole.The Chinese government in 2005, which promises to undertake, stops using 1211 halon fire agents, phosphoric acid Ammonium salt powder extinguishing agent is increasingly valued by people because fire-fighting efficiency is high,

ABC ultra-fine dry powder extinguishing agents using MAP as base material at present, because dry powder particles particle diameter is larger, are not easy to be suspended in Ignition zone, efficiency is low, and dosage is big, it would be highly desirable to solves.

The content of the invention

Based on technical problem existing for background technology, the present invention proposes a kind of small particle ABC powder extinguishing agent and its system Preparation Method, manufacture craft is simple, and production cost is low, environmental sound, and gained powder extinguishing agent diameter of particle is small, the disperse of particle Property, suspension it is good, the endothermic reaction is fast, captures free radical ability extra-heavy, and fire extinguishing is swift in response, and fire extinguishing effectiveness greatly promotes, and is general 10-14 times of logical powder extinguishing agent efficiency.

A kind of preparation method of small particle ABC powder extinguishing agent proposed by the present invention, comprises the following steps：

S1, nano-calcium carbonate, stearic acid, myristic acid stirred, add microcrystalline wax, water and be well mixed, under stirring Sulphation enuatrol is added, heating stirring, filters, washing, dry, pulverize to obtain first material；

S2, MAP, potassium dihydrogen phosphate, potassium hyperchlorate, glass fibre, first material be well mixed, homogenization Obtain second material；

S3, containing hydrogen silicone oil, water is well mixed, adds acetone and stir, obtain mixed material；By mixed material mist Change the second material for spraying into and being in stirring, heating is well mixed, goes to remove water, and adds nano silicon, magnesium stearate, Vacuum crushes to obtain small particle ABC powder extinguishing agent.

Preferably, in S1, nano-calcium carbonate, stearic acid, myristic acid, microcrystalline wax, the weight ratio of sulphation enuatrol are 60-80：2-4：2-4：8-16：4-10.

Preferably, in S1, it is warming up to 90-96 DEG C.

Preferably, in S2, MAP, potassium dihydrogen phosphate, potassium hyperchlorate, glass fibre, the weight ratio of first material are 100-120：20-40：10-20：6-12：6-10.

Preferably, in S2, the homogenization time is 10-20min, homogenization pressure 4-8kPa.

Preferably, in S3, containing hydrogen silicone oil, water, acetone, second material, nano silicon, the weight ratio of magnesium stearate are 2-4：6-12：4-8：100-160：10-20：2-4.

Preferably, in S3, it is warming up to 80-88 DEG C；Vacuum is crushed to grain diameter less than 10-20 μm.

A kind of small particle ABC powder extinguishing agent proposed by the present invention, using the preparation of above-mentioned small particle ABC powder extinguishing agent Method is made.

The present invention has height using MAP, potassium dihydrogen phosphate, potassium hyperchlorate, glass fibre, first material compounding It is the characteristics of nitrogen, high phosphorus, high to B, C class fire fire extinguishing effectiveness；In the first material of the present invention, nano-calcium carbonate, stearic acid, myristic acid Compounding, good dispersion, is not easy to reunite, and the alkyl chain of sulphation enuatrol imparts the characteristic of nano-calcium carbonate oleophylic, and sulphur Acid ion can effectively prevent the reunion of calcium carbonate particle, sulphation enuatrol and MAP, potassium dihydrogen phosphate, potassium hyperchlorate Compound, strong acid is produced after pyrolytic and produces gas with fibrin reaction, there is high-effect fire-extinguishing effect to A class fire, and The particle diameter of first material is minimum；And first material and MAP, potassium dihydrogen phosphate, potassium hyperchlorate, glass fibre, nano-silica SiClx compounds homogenization, makes that gained powder extinguishing agent powder is prevented from caking, and diffusivity is good, and easily suspend space on fire, is formed steady Fixed aerosol, the endothermic reaction is fast, captures free radical ability extra-heavy, and fire extinguishing is swift in response, and fire extinguishing effectiveness greatly promotes, and is common 10-14 times of powder extinguishing agent efficiency, and manufacture craft is simple, and production cost is low, environmental sound.

The performance indications of gained powder extinguishing agent of the invention meet GA 578-2005 relevant criterion, and fire extinguishing effectiveness is less than Equal to 80g/m³, it is not more than 150g/m better than regulation³Requirement, and gained powder extinguishing agent grain diameter is small, the disperse of particle Property, suspension it is good, the total flood fire suppression of ABC class fire can be achieved, while in the case where humidity is 90% high humidity environment, hygroscopicity It is minimum, it is not easy to caking phenomenon occur, can stores for a long time, and foamite amount that can be easily less reaches fire extinguishing in shorter time Effect.
