Fire and its discovery is one of the most important events in human history, with a tremendous impact on human development.
- fire in addition to its vital function for humans, fire also has a disadvantage, namely its property of burning objects, which causes numerous material and financial losses in our society every year. Almost flammable materials and materials are dangerous because they are prone to catch fire and ignite fires. Therefore, it is important to find an effective way to provide such flammable materials with flame and / or fire protection which makes such materials and substances less dangerous.

Flame retesting tests must be performed vertically in order to provide the required fire protection certificates. In this case, the flamed vertically arranged material, ie the vertical insulation or the vertical wall covering, must neither melt nor drip in order to pass the required fire protection test and fire protection class. This has not been successful in the prior art, as catastrophic fires of styrofoam in particular and also based on wood and cellulose products insulation and wall coverings even in the recent past still show.

- Expanded graphite also known as “expandable graphite” is made from the naturally occurring mineral graphite, a graphite flake consisting of layers of honeycombed carbon atoms, within which the atoms are very tightly bound by covalent bonds, with only weak binding forces between the layers so that molecules can be intercalated (intercalated) between the graphite layers, and the incorporation of acids, usually sulfuric acid, converts graphite into expandable graphite.
- the graphite flakes expand according to their quality, from a temperature of approx. 140 ° C to a multiple of the original volume. By evaporating the embedded compounds, the graphite layers are driven apart like an accordion.
- the expanded flakes have a "worm-like" appearance and are usually several millimeters long.
- Physical properties of expanded graphite carbon content 85-99% by weight; Expansion rate 30 - 400 cc / g; Particle size 80% ⁇ 75 ⁇ - 80%> 500 ⁇ ; Starting temperature 140 - 230 ° C.
- For the production of expanded graphite natural graphite flakes are treated in a bath of acid and oxidizing agent.
- oxidants are hydrogen peroxide, potassium permanganate and chromic acid, the latter of which may involve after-effects.
- Concentrated sulfuric acid or nitric acid are usually used as the compound to be stored, the reaction being carried out at temperatures of 30 ° C. to 130 ° C. for up to four hours. After the reaction time, the flakes are washed with water and then dried. Start temperature and expansion rate depend on the fineness of the graphite.
- One of the main applications of expanded graphite is flame retardancy. When exposed to heat, expandable graphite expands and forms an intumescent layer on the material surface. This slows down the expansion of the fire and counteracts the most dangerous consequences of fire for humans, namely the formation of toxic gases and smoke.
- the expandable graphite can be used either alone in the production of flame-retardant and / or fire-protected products consisting of or comprising wood fiber and / or cellulose fiber materials or it can be used as a mixture together with the above-described flame and / or fire retardant according to DE 10 2015 1 19 558.5 are used, which will be explained below with reference to two exemplary embodiments.
- the amount of expandable graphite in a wide range of amounts for example up to 60% by weight expandable graphite, based on the amount by weight of the wood fibers used, is 100% by weight, be varied; the minimum amount of expandable graphite may be, for example, 0.1% by weight, 0.5% by weight, 1% by weight, 2% by weight, 3% by weight, 4% by weight, 5% by weight.
- the superset of expandable graphite may be, for example, 55% by weight, 50% by weight, 45% by weight, 40% by weight, 35% by weight, 30% by weight or less, in each case based on the amount by weight of the wood fibers used as 100 wt .-%; Intermediate values of the stated supersets in% by weight are likewise possible, for example in 0.1% by weight increments, 0.5% by weight increments and / or 1% by weight increments.
- intermediate values The stated ranges of minimum quantity and upper quantity in% by weight are likewise possible, for example in 0.1% by weight increments, 0.5% by weight increments and / or 1% by weight increments, each independently of one another of minimum quantity and superset.
- Polymeric diphenylmethane diisocyanate was used as binder for the fibers.
- Polymeric diphenylmethane diisocyanate also called technical MDI, is a mixture of methylene diphenyl isocyanates and homologous aromatic polyisocyanates.
- polymeric diphenylmethane diisocyanate is incorrect, it is not a polymer, but the mixture contains compounds with several (typically up to 6) phenylene groups, each carrying an isocyanate group, a common trade name is also polymethylene polyphenyl isocyanate
- Wood-based panels are a precursor for the production of polyurethanes and are prepared by phosgenation of 4,4'-diaminodiphenylmethane (an MDA) and its homologs, which in turn is prepared by condensation of aniline with formaldehyde
- the composition and properties of the PMDI with regard to reactivity and thus its applicability as a binder are influenced essentially by the following factors: proportions of the MDI isomers (4,4'-MDI, 2,4'-MDI, 2,2'-MDI); Molar mass distribution PMDI is a brown, very flammable liquid (Flam above 200 ° C), which has a
- the melting point is about -24 ° C. At 20 ° C, the density is around 1.23 g. "3 With regard to wood-chip materials with PMDI, PMDI has some advantages compared to other adhesives used in the wood-based panel industry, which justify the higher price, especially for applications with higher moisture resistance requirements or formaldehyde emission: Hydrolysis resistance; free of formaldehyde; lower binder requirement.
- wood fibers (with residual moisture) were introduced into a concrete mixer and mixed therein with added expandable graphite (a wide range of 1% by weight - 60% by weight addition of expandable graphite is possible). Then, a PMDI solution was sprayed, the mix was poured into a mold and pressed with 170 tons at 200 ° C to a plate.
- the wood fiber product thus produced has sufficient strength and shows after 10 min. Flame no burning, no afterglow, The temperature of the fire area dropped abruptly. Expanded graphite has an intimate effect and blooms at the point of fire, prevents the ignition of the cellulose or wood fibers, does not allow the temperature inside the fiberboard to increase, disappears immediately after the flame has been removed, and does not glow. Thus, a classification in the fire protection group B1 would be no problem, if necessary, it could also be sufficient for A1, if expanded graphite When puffing does not escape excessively in the form of ash and thus does not significantly lose the product of total weight.
- wood fibers were first placed in boric acid / borax / salt solution or completely soaked and then dried again. Then, the treated wood fibers were filled as in the previous embodiment in a concrete mixer and also sprayed with PMDI, then filled into a mold and pressed with 170 tons at 200 ° C to plates.
- the strength of the fiberboard was also very good, it does not burn, the burning surface radiates some temperature, the afterglow is very low and after 20 min. No afterglow could be observed, the temperature decreased rapidly, and any embers were completely extinguished.
- the present invention therefore also provides in a further embodiment, a surprisingly simple combination and / or simple mixture of expandable graphite together with the agent according to DE 10 2015 1 19 558.5 for reducing the flammability and / or flammability of products made of wood - And / or cellulose fiber materials, in particular a flame retardant and / or fire retardant available, which, in contrast to the material-specific means of the prior art, surprisingly allows a much wider range of applications. For example, it is therefore suitable only for minimal adaptation effort for the respective field of application and for a wide range of applications.

After sufficient mixing, the treated wood fibers were pressed under high pressure and temperature into wood fiber insulation boards.
