Insulation

In all industries is an insulation material that can be used I cotton.

Conventional insulation material, and especially asbestos insulation resulted in a nationwide health damage, at present, there is no an alternative to Re this.

  Airborne asbestos fine fibers and the pathogenic characteristics of asbestos have caused great damage to human health.

Further, not limited to asbestos, in the glass fiber which has been used conventionally, even melting temperature 600 ° C. before and after with the glass itself, once fiberizing, a maximum 400 ° C. from 300 ° C., the used building materials Glass fibers with aluminum stays have the disadvantage that they are ignited and burned at 200 ° C. or more with adhesives.

Also, insulation, as thermal deterioration of strength defense metals particularly in fire, the shortest distance in place of asbestos, but Ru Oh intensity Ngong evolution of the glass fibers are produced in a known fact, high Yutakaka a conventional 400 ° C. There is no meaning in the fire, and the processing which can endure glass fiber to higher temperature was desired.

In particular, a physical property that is not a heat insulating material is not worth using, but there is a demand for a technique for changing it to a heat-resistant material at around 900 ° C. by processing it.
JP-A-5-296387

As mentioned above, it is also sufficient conventional glass fiber if Shoeneru formic adiabatic effect purposes required just daily, once the glass in the use of heat-resistant material in an environment when the fire, or comparable to that There is the following problem to make glass fiber that can be used as an alternative to asbestos in an environment that is completely meaningless and not worth using.

Is characteristic of fiberglass, higher tensile strength than the piano wire of the same diameter, although weak drawbacks flexion may correspond with a fine diameter of a diameter, heat resistance causes rapid deterioration if exceeds the 300 ° C..

  Alkali-free special glass fibers are also heat resistant at 400 ° C., but are not suitable for use in a fire or the like or in a temperature environment comparable to that.

In particular, among the many various materials, as long established technique for flammable materials nonflammable, exponentially application is enlarged.

In order to solve the above-described problems, the heat insulating material according to the present invention is characterized in that a base material is impregnated with sodium silicate.

The substrate, insulation silicate Natoryuumu is being impregnated coated, be construed as being also used for coating materials used in the 1600 ° C. or higher temperature environment of arc welding rod, nor between heat resistance holding said .

By applying and impregnating sodium silicate with a heat-resistant material at 300 ° C. to 400 ° C. , the heat-resistant performance is improved and the heat insulating performance is improved .

Second, activated carbon plates of plant material, or granules, coating also entered a non-combustible, from the fact that the meaning of the heat insulating material is eliminated if disappear incinerated at high temperatures, these silicate Natoryuumu Impregnation prevents the ash from disappearing and adds heat insulation performance.

  The other is that a combustible material is changed into a non-combustible material by impregnating it with a material far from the incombustible material, such as vegetable cotton or resin corroded cloth.

For example, the resin fiber nonwoven fabric is simply impregnated with sodium silicate silicate so that it does not infiltrate the resin fiber itself. The thinner the fiber, the more it adheres to the periphery of the fiber due to the capillary phenomenon of the nonwoven fabric. only blackening carbonized at a depth of .5mm, changes to nearly complete thermally resistant material.

However, a large flammable objects, unfortunately only when applying impregnation available-for surface sites without impregnation to the core, it core sites are flammable maintained unavoidable.

At present health hazards of asbestos have been frequent after the lapse of a few tens of years, as soon as possible, in the development of its generation Kawabutsu quality are urgently needed, select closer geometric kind of non-combustible substances other than asbestos the there combustibles, that a heat insulating material by silica Natoryuumu impregnation coating, combined also with economy, exerts significant benefits.

At the same time, the environmental recycling, from the viewpoint of saving energy formic, turned into 砕粉 broken thinned wood, if impregnated coated silicate Natoryuumu, are also possible over the heat-resistant material rock wool, simultaneously, silicate waste paper pulp Natoryuumu When impregnated, the same effect as sprayed rock wool material was demonstrated, and the story of the dream that the steel spray was made of paper was actually demonstrated.

The following will explain the actual施例, prior to, referred to properties of silicate Natoryuumu.

Although dry and wet is present in preparation of silicate Natoryuumu, both of silica sand or the raw material silicate clay and soda ash or caustic soda, do not harm health.

Although differences in various efficacy by the ratio of the silica sand and soda ash is produced, it is selected by the noncombustible treatment counterparts.

Heat effect of the flame radiation by coating impregnated silicate Natoryuumu liquid to an object is to an example, the processing object is a tissue Bae over path over, despite there ultra combustibles, 2 mm silicate Natoryuumu solution dipping the plate-like drying, carbonization of depth of the flame sites 1mm to 1.5mm, carbide site becomes heat insulating layer, even if one point focused bar training in Butangasuba over Na over until the following deep 1.5mm carbonization does not proceed, the back is quite bar training before 2mm thickness and color without any change, represents the thermal insulation and fire resistance.

(Filamentous) aggregate of glass fibers, for example, between the fibers of the glass fiber B-loop or fiberglass insulation, silicate Natoryuumu solution, adhesion at the adhesion agent to the glass fiber surface, the heat resistance by impregnating adhesion holding, if represents the heat effect adhesion agent is hot, such as may be flame retardant of or fireproofing also adhesion agent by silica Natoryuumu be heated to a high temperature of a fire.

The glass fiber nonwoven fabric, by impregnation coating a silicate Natoryuumu solution, capillary action only nonwoven likewise very embrace many silicate Natoryuumu solution, heat effect increases but there is also cost issues, as a processing method, the glass fiber nonwoven fabric by passing the silicate Natoryuumu solution bath, squeezed with a double-sided b over La chromatography, was dried, vertically, or horizontally Russia be squeezed by applying over La chromatography fullest pressure and no change in functional It was.

The glass fiber woven fabric impregnated with sodium silicate solution was processed for the purpose of improving the heat resistance of glass cloth used for FRP reinforced plastics and the like, and for reinforcing materials for flame retardant resin molding. the combustion test of FRP reinforced plastic plate of the present invention, even after the resin has been extinguished combustion at 500 ° C. bar training trials, the last until the remaining is given and a glass fiber woven fabric silicate Natoryuumu solution impregnated coating.

The glass fibers of cotton, if impregnated coated silicate Natoryuumu solution, born at all hot incombustible cotton, asbestos spraying process similar working process, it was possible to work blown building nonflammable .
Further, combustible liquid, or even heat-insulating material co computing the transfer pipe fittings such as combustible gas, represents the effect that at all over asbestos.
In this case, as an example, a glass cloth or mosquitoes over Bonkurosu selected at the level of temperature control, a glass fiber cotton impregnated coated dried silicate Natoryuumu solution wrapped in cushion manner, the object by covering the pipe joint Played.

A pulp paper, which was impregnated coated silicate Natoryuumu, most uni over those were click is impregnated into cotton-like paper of used paper recycling process, blown into the steel construction materials, asbestos similar purposes have been achieved It is a thing.

Further, silicate Natoryuumu solution impregnated coated with paper recycling stage, if compacted dry, full heat board is formed.

Notably other is in a dissolved iron sampling steel mill blast furnace, silicate Natoryuumu solution was impregnated applied to the paper tube, the sampling of the thousand several hundred degrees of dissolution of iron, it could be used although the predetermined time even It is.

At the same time, the most dangerous engine Le chromatography beam during tunnel fires with motorization, a flash hazard prevention from outside, even at 400 ° C. firing untestable the carburetor filter paper, no reduction in the filtration function, impregnation coating The effect was improved only by adjusting the concentration.

Forget impregnated coated workpiece must is a shoji paper indispensable to Japanese building, only diluted silicate Natoryuumu solution sprayed on shoji paper, only be directly attached to the flame of the writer over, black carbonized It was a phenomenon with no smoke.

The plant properties flocculent pulp, by impregnating coating a silicate Natoryuumu solution, can be variously shaped molded by embossing drying, becomes a replacement cash asbestos type moldings that are used in the automobile muffler, this type the product is not limited to being this, it is also possible in a variety of materials.
