Description

Composition of fire proofing materials

The present invention relates to a fire extinguishing composition for improving fire extinguishing efficiency in the event of a fire, such as fire suppression of large and small fires, and electrical facilities, warehouses or transportation means of industrial facilities.

Fire suppression acts to inhibit the activation of sparks by condensation of aerosols.

This product can be used successfully for large fire fighting.

-Solid combustion such as wood, coal, fiber polymer products

-When burning liquids such as benzine, diesel fuel, alcohol, ether, glycol, etc.

-Gas combustion such as hydrogen, methane, propane or mixtures thereof

When burning metals such as Al, Mg or alloys such as light metals, alkali metals such as K and Na, metal-containing compounds, metal hydroxides and metal organics

In the event of a large firefighting, the use of products in confined spaces, such as homes, docks, factories (defense spaces), etc., prevents them from sustaining combustion. This releases gases or aerosols into the defensive space and distributes them evenly in the space to ensure proper concentration, making it impossible to explode during combustion.

Background Art Conventionally, a flame production method (WO, application N0.92 / 17244 class A62D 1/100, 1992) containing an alkali metal salt acetic acid or an alkali metal, chlorate and a flammable compound is known.

The impediments to obtaining the necessary technical results for the use of a given product are the low mechanical strength of the product and the very narrow range of temperature and humidity available.

Extinguishing compounds are also known to contain components dispersed upon heating, oxidizing agents, oxygen-containing compounds and additives such as plasticizers, combustion modifiers and the like. (WO, application N0.93 / 14820 class A62D 1/100, 1993)

Reasons to hinder the use of the product include the use of difficult transportation means, the need for water absorbing devices and the use of spray components that inhibit complete combustion, leading to increased consumption of extinguishing compounds.

The present invention to solve the above problems

It is possible to provide a fire extinguishing composition with improved use characteristics by reducing the comparative use amount of the composition through the expansion of complete combustion and combustion products that do not cause global ozone layer destruction.

The essence of the present invention is to improve the use characteristics (high mechanical strength, wide temperature and humidity ranges) by reducing the comparative amount of extinguishing composition. This is possible by enlarging complete combustion in a constant quantitative balance of potassium perchlorate and potassium nitrate in the essential premise of the combustion composition.

Such a combination reduces the potassium perchlorate content to the extent that it does not destroy the earth's ozone layer.

The use of technical additives in the form of diaminediallate stearic acid or lecithin significantly improves the gas liquid properties of bulk mixtures. This leads to a reduction in comparative energy and an improvement in product quality (reduced porosity) in the production of composites, i.e. an improvement in the characteristics of comparative consumption from preparation to preparation.

Oxygen-containing compounds bind all components and regulate the balance of oxygen during the combustion process.

As a supplementary ingredient, barium nitrate is included in the combusted product, which provides an extinguishing composition to increase the oxygen balance of the compound and reduce the CO of the combusted product.

Hereinafter, the present invention will be described in detail.

The extinguishing agent composition of the present invention comprises an oxygen-containing compound, a combustion regulator, a plasticizer and technical additives in the form of an oxidizing agent of potassium perchlorate and potassium nitrate, an epoxy resin or an elastic rubber, or a mixture thereof, which is a ratio of potassium perchlorate and potassium nitrate. It is characterized by including the oxidizing agent in the form of mixed from 1: 1 to 1: 5, respectively, and the metal oxide as the combustion regulator as the mass ratio below.

(bottom)

Of potassium perchlorate and potassium nitrate

  Oxidizer in the form of a mixture (1: 1-1: 5 weight ratio) ... 50.0-80.0 wt%

-Oxygen-Containing Compound ............... 10.0-30.0% by weight

-Plasticizer ...................................... 2.0-8.0Weight %

-Combustion regulators ............... 0.1-2.0 wt%

-Technical Additives ................................... 2.0-16.0 wt%
-Barium Nitrate ......................................... 5.0-15.0 wt%

Here, the addition of 5.0-15.0% by weight of barium nitrate improves the oxygen balance and improves the ignition conditions.

Here, metal oxide is used as the combustion composition, and manganese dioxide, nickel oxide, copper oxide, iron oxide or a mixture thereof is used.

As technical additives to improve the flow characteristics of the components in the manufacturing process, it is better to use surfactants such as diaminedilate stearic acid, lecithin, or mixtures thereof. This is essential as a curing agent for oxygen-containing compounds.

In order to achieve better results, it is necessary to use dibutylphthalate, dibutyl sebacinat, dioctyl sebacinat, glycerine triacetate, sodium oleate, oleic acid or mixtures thereof as plasticizers.

The information supporting the feasibility of the product applying the techniques shown above explains the specific method of making the composition.

The components required to prepare the composition are as follows:

Potassium perchlorate TU 6-02-627-78, potassium nitrate tech, GOST¹19790-74, reac. GOST 4144-79, barium nitrate GOST 1713-79E.

-Epoxy resins AD-20 GOST 10587-84, AD-16 GOST 10587-84, AD-5 GOST 10587-84, polybutadienenitrile rubber SKN-26, SKN-18 TU 38-10316-76.

-Dibutyl Phthalate GOST 8728-77E GOST 8728-77E, Dibutyl Sebacinat GOST 8728-77, Dioctyl Sebacinat GOST 8728-77, Glycerin Triacetate TU 6-09-4960-81, Oleinate Tyl 6 -14-1000-73, modified oil GOST 928-80.

-Metal oxide as combustion regulator: Manganese dioxide tech. GOST 25823-83, c.d.a. GOST 4470-79, zinc oxide GOST 10262-73, copper oxide GOST 16539-79, iron oxide GOST 8135-74, nickel dioxide GOST 4337-78, aluminum oxide TU 48-51-77.

As technical additives, surfactants include diaminediallate stearic acid, cationic-7 TU 6-14-101874, lecithin TU 6-02-829-78 or mixtures thereof.

In addition, as a technical additive, as a curing agent for oxygen-containing compounds, a curing agent well known for this purpose, for example, polyethylene polyamine, tetrahydrophthalate anhydride TU 6-09-3321-73, chinoline ether TU 6-09-51376, thiuram E GOST 6-14-147-73, sulfur GOST 127-76 or mixtures thereof.

Prepare the composite as follows. Viscous oxygen-containing compounds, plasticizers, surfactants, and combustion modifiers are added to the mixer. Mix the ingredients for 10-15 minutes at 25 ℃. Add the oxidant to the resulting mixture and vacuum all the components simultaneously and mix for 90 minutes. Then add the technical additives and mix for 10-15 minutes. The material thus obtained is injected into a mold of constant size in vacuo and maintained at the same temperature conditions until solidified. If necessary, the product removed from the mold may be mechanically processed.

The composition according to the prototype is prepared in accordance with the records introduced in the application WO No. 93/14820. Table 1 shows the quantitative and qualitative balance of the components.

Table 2 shows the results of the experiments for all compositions, both components and prototypes. The composites were tested for resistance to physicomechanical strength, temperature and humidity action. In the heating and humidity chambers, the samples are tested to withstand such an environment and the extinguishing efficiency is measured in a 0.2 m3 model box.

The amount of extinguishing agent available for complete extinguishing of the fire source was calculated. Three experiments were conducted for every example, where `` + '' indicates that the fire source was extinguished and ``-'' indicates not.

Experimental results show that the extinguishing component has superior mechanical strength and has a usable temperature range of -60 ° C to + 125 ° C when the relative humidity is 95% or less.

At this time, the consumption of digestive components (digested concentrate) is about 20-28g / ㎥, in the case of the prototype under similar conditions the consumption is 48-58g / ㎥. At this time, the prototype component contains a considerable amount of chloride, which worsens the corrosion characteristics.

In addition, the extinguishing composition according to the functional features has a smaller amount of components than the composition according to the prototype. Extinguishing media does not contain components dispersed by heat. This does, however, improve rather than deteriorate the usage characteristics.

The quantitative balance of the extinguishing composition is described below.

It is essential to include potassium perchlorate and potassium nitrate in a 1: 1-1: 5 ratio as the oxidant of the composition. This increases the complete deformation of the composite. In addition, barium nitrate may be included in the component. This increases the oxygen balance of the composition to reduce the CO of the combustion products. Mass dosing of oxidants deteriorates the gas liquidity of the composition and renders it impossible to produce a good quality product. When a small amount of oxidant is added, the extinguishing effect is noticeably lowered due to increased slag residue and carbon black generation in the combustion material.

As described, changing the oxygen-containing adhesive component, on the one hand, increases its combustion capacity by 30% or more (similar to oxidizing agent reduction), and on the other hand, decreases its hardness by 10% or less. Worsens.

Incorporating a burn modifier into the compositions described will yield the desired burn rate. If the content of the combustion modifier is less than 0.1%, no effect on the component properties is found. Increasing the combustion modifier to 2.0% or more raises the K phase without affecting the combustion rate.

If the plasticizer content is in the range of 2.0-8.0, the composite can avoid fragility and the mechanical hardness is maintained. Composites are available from 10 g to 100 kg and larger amounts may be used depending on the structure of the aerosol gas generator and the specific size of the protective space.

By using this extinguishing agent, liquids and solids generated in any production activity space corresponding to the engine compartment and fire law requirements of various vehicles with high humidity and high mechanical loads (vibration and shock) with a wide range of available temperatures. Effective for fire extinguishing

The fire extinguishing composition of the present invention as described above has an effect of improving the fire suppression efficiency in the event of a fire in an industrial electrical installation, a warehouse, a vehicle mechanism, or the like.
