Description
Technical field
The invention belongs to the aerosol fire-extinguishing technical field, particularly relate to a kind of aerogel generating agent and preparation technology thereof.
Background technology
Aerosol extinguishing agent is that a kind of fire-fighting efficiency is high, and ozone depletion value ODP is zero, and is nontoxic; Noresidue; The fire-extinguishing agent that price is low, equipment investment is few breathing out under the superseded urgent background of dragon, had both obtained the active support of the government; Also catered to the demand in market, so the aerosol fire-extinguishing technology becomes one of imperial substitute technology in very noticeable Kazakhstan in recent ten years.
Aerosol has the extinguishing property height as the substitute products of breathing out imperial product, and characteristics such as non-secondary pollution, the industry of at home and abroad putting out a fire have very to be used widely.In the existing product, the prescription of this type propellant mainly comprises oxidant, reducing agent, adhesive, additive and processing aid etc.In these prescriptions, selects suitable material, can not only improve the fire extinguishing effectiveness of propellant greatly, also can improve the processing of propellant, storage, performance such as use and these performances also are the indispensable parts of aerogel generating agent.
Number of patent application is that it is main having used with potassium nitrate, melamine, phenolic resins in the patent documentation of CN99115863.6; The potassium ferricyanide and saleratus etc. are the prescription of assisting; Adopt dissolve with ethanol phenolic resins; The phenol resin solution concentration of processing is 10%～30%, and the fire-fighting efficiency of this patent propellant is 30～40g/m3.U.S. US6042664 (1998.07.21) number patent also discloses a kind of aerogel generating agent; Its propellant quality group becomes: potassium nitrate 67%～72%; Phenolic resins 8%～12%, dicyandiamide 9%～16%, surplus is saleratus, the potassium ferricyanide or Potassium Benzoate.This fire extinguishant compositions proves through formula test, and the gas production when using dicyandiamide is lower, and this patent propellant fire-fighting efficiency is 35～45g/m3.Normally used reducing agent melamine, dicyandiamide etc. in the aerogel generating agent are alkaline matter now.If fire extinguishing object is a slant acidity, some acid equipment generation burn into is damaged.As: oil tank catches fire, though use existing aerosol extinguishing agent to put out a fire, thus the material of alkalescence can make some the composition generation saponification flocculation in the crude oil, impacts for the performance of crude oil, and influence reuses.
Summary of the invention
In order to solve the problem that exists in the prior art, the invention provides a kind of fill a prescription form simple, gas production is big, sufficient combustion and be more suitable for the aerogel generating agent and the preparation technology thereof of acid fire extinguishing object.
The technical scheme of technical solution problem of the present invention is:
A kind of aerogel generating agent is made up of oxidant, reducing agent, adhesive; Described oxidant is a potassium nitrate, and adhesive is a phenolic resins, it is characterized in that: described reducing agent is one or more in tartaric acid, dihydroxytartaric acid, ethylenediamine tetra-acetic acid, salicylic acid, the phthalic anhydride.
The quality percentage composition of reducing agent is 5%～50% in the said aerogel generating agent.
Further, its quality percentage composition of each component is in the said aerogel generating agent:
Oxidant 65%～78%
Adhesive 9%～15%
Reducing agent 8%～20%.
Further, its quality percentage composition of each component is in the said aerogel generating agent:
Oxidant 68%～75%
Adhesive 10%～12%
Reducing agent 15%～20%.
Another object of the present invention is to propose a kind of preparation technology of aerogel generating agent, it is characterized in that:
1) phenolic resins is dissolved in the ethanol, processes mass percentage concentration and be 50%～65% phenol resin solution;
2) Oxidizing and Reducing Agents is crushed to the fineness of 100-200 standard mesh, and requires in proportion to mix, and cross three times, it is mixed with 100～200 mesh sieves;
3) then phenol resin solution is added among the powder mix; Use 40 mesh standard sieve net granulations after forcing mix to stir; And the particle that will make, 25 ℃～55 ℃ of temperature, be dried in the environment of humidity below 30% that volatile content is not more than 1% in the composition.
4) medicament that drying is good is in the pressure pressed moulding at >=3MPa.
In the fire-extinguishing composite of the present invention, reducing agent adopts acidic materials such as tartaric acid, dihydroxytartaric acid, ethylenediamine tetra-acetic acid, salicylic acid, phthalic anhydride to be different from the alkaline reducer of available technology adopting.Having remedied on the one hand present conventional patent uses the aerosol extinguishing agent effect that contains alkaline reducer relatively poor or use the defective of back to the more negative effect of generation of protected object in some field; As when crude oil is put out a fire; Because crude oil itself is faintly acid; If adopt the aerogel generating agent that contains alkaline reducer; Then the aerosol of alkalescence can cause propellant and oil composition each other saponification to take place and the chance that produces flocculation increases greatly; This makes troubles for subsequent treatment of crude oil, and the aerogel generating agent that the aerogel generating agent of acidic materials such as tartaric acid, dihydroxytartaric acid, ethylenediamine tetra-acetic acid, salicylic acid, phthalic anhydride combination produces is faintly acid, in fire extinguishing, can not react with oil composition and has stopped this negative effect; On the other hand; In the use of fiting chemical cooling agent; As adopt acid chemical coolant, just need acid or neutral aerogel generating agent to cooperate, otherwise the two influence each other and can reduce the storge quality and the fire extinguishing effectiveness of propellant and chemical coolant greatly.Therefore aerogel generating agent of the present invention is to having replenishing of aerosol extinguishing agent, also is the expansion to its application.
With respect to prior art, the invention has the advantages that:
1) aerogel generating agent of the present invention can use as extinguishing chemical separately, also can use by the fiting chemical cooling agent, as the heating power source and the power source of chemical coolant.
2) aerogel generating agent stable performance of the present invention, be easy to long term storage, environmentally friendly function admirable.
3) aerogel generating agent of the present invention adopts the acidic reduction agent, is more suitable for the fire extinguishing object of slant acidity, effectively can effectively avoid making some acid equipment generation burn into to damage in the fire extinguishing, and influence reuses.
4) the present invention carries out preferably making it under preparation process condition according to the invention to the ratio of each component in the aerogel generating agent, can fully burn, and propellant combustion residue amount is littler.
