Definitions
- the invention relates to a method for flame and fungus protection of insulating materials from renewable raw materials, the use of an impregnation solution for flame and fungus protection of insulating materials from renewable raw materials and flame and fungus-proofing insulating materials made from renewable raw materials.
- a large number of substances are available as commercial flame retardants. Flame retardants effective in wood work, for example, in that they emit flame-emitting gases or have a carbonizing effect in the heat of fire, as a result of which a well-insulating layer of charcoal is formed on the wood.
- ammonium hydrogen phosphate which releases ammonia in the heat and thereby forms dehydrating and thereby carbonizing phosphoric acid, mixtures of urea, dicyandiamide, melamine and organic phosphates, and also mixtures which additionally contain chlorinated paraffins, the latter providing chlorine-containing gases which act as radical scavengers.
- the use of such flame retardants is not without dangers, since the reduction of a fire risk in the event of a fire contrasts with the possibility of environmental hazards.
- Toxic phosphates can be formed, halogenated compounds can form atmospheric or persistent residues during combustion, and the formation of highly toxic dioxins cannot be excluded during combustion processes in the presence of organic chlorine compounds. Intensive work is therefore being carried out on the development of less environmentally hazardous flame retardants.
- fungistatics and fungicides include organometallic compounds of heavy metals such as mercury or cadmium, as well as organotin compounds, copper salts, chloronaphthalenes and chlorophenols. Since these substances have an intensive effect on living organisms, there is basically a potential hazard to human health when they are used. Only wood preservatives that have been tested by the Institute for Building Technology and approved for the intended use may therefore be used for wood protection measures prescribed by the building authorities. In addition, toxic substances are out of the question for building materials that are supposed to meet the requirements of ecological building. In addition to their harmlessness in terms of building biology, the flame and fungus protection agents used must meet processing requirements and must not push the price of the building materials treated with them too high. From US 4,780,341 sodium carbonate solution is known as a wood preservative with a flame-retardant and anti-fungal effect. The use as an impregnation agent for plant shives or fibers is not mentioned.
- aqueous carbonate solutions were used as flame retardants for wood chips and plant fibers.
- the object of the invention is to provide a biologically harmless flame retardant for the flame retardant finishing of insulating materials made from renewable raw materials, which meets the requirements for ecological construction. Another object of the invention is to provide this in conjunction with a building biologically harmless fungus protection agent.
- the flame and fungus protection agents used should be inexpensive, easy to work with and should not impair the insulating materials treated with them in terms of their structural properties.
- the problem is solved by a process for flame and fungus protection of insulating materials from renewable raw materials, in which the insulating material with an aqueous impregnation solution containing 5 to 20 wt .-% sodium and / or potassium carbonate as flame and fungus protection agent and an additional 2 to 10% by weight of a surfactant is impregnated as an anti-fungal agent, characterized in that the insulating materials scrape off hemp, miscanthus, flax, jute and ramie as well as insulating mats made from the fibers of hemp, miscanthus, flax, ramie and new wool are. All concentration data refer to sodium or Potassium carbonate.
- Insulating materials made from renewable raw materials are natural fibers (bast fibers) obtained from fiber plants, such as hemp, flax, miscanthus (Chinese reeds), also new wool, and building textiles made from them, such as nonwovens, felts, fabrics and wadding.
- Insulating materials made from renewable raw materials are, in particular, plant stems (natural shives), such as the cockroaches from hemp, miscanthus, flax, jute and ramie.
- Preferred insulation materials which are treated with the aqueous impregnation solutions according to the invention are the natural shives mentioned, in particular the cockroaches of the hemp plant, which are used, for example, as loose embankments in the floor or partition wall area, and insulation mats made of natural fibers, such as random fiber insulation mats, in particular insulation mats made from Fibers from hemp, flax, miscanthus, ramie and new wool.
- the impregnation solutions used in the process according to the invention contain 5 to 20% by weight of sodium and / or potassium carbonate as flame retardants.
- the aqueous impregnation solutions preferably contain 15 to 20% by weight, particularly preferably 18 to 20% by weight, of sodium or potassium carbonate.
- the flame-retardant effect of sodium or potassium carbonate in the flame retardant impregnations according to the invention is presumably due to the decomposition of the carbonates in the heat of fire with the release of CO 2 , which has a flame-retardant effect.
- the invention also relates to the use of sodium or potassium carbonate for the flame and fungus protection of insulating materials made from renewable raw materials.
- the invention relates in particular to the use of an aqueous impregnation solution containing 5 to 20% by weight, preferably 15 to 20% by weight, particularly preferably 18 to 20% by weight of sodium or Potassium carbonate as a flame and fungus protection agent for the aforementioned insulation materials made from renewable raw materials.
- the impregnation solutions used in the process according to the invention can additionally contain a further antifungal agent.
- a further antifungal agent all antifungal agents with a fungistatic or fungicidal action, which are ecologically and biologically harmless and soluble in the aqueous impregnation solution, are suitable.
- Suitable, ecologically and biologically harmless antifungal agents are surfactants such as soaps or synthetic detergents.
- the aqueous impregnation solutions contain 2 to 10% by weight, preferably 5 to 10% by weight, particularly preferably 5 to 8% by weight, of a surfactant as an antifungal agent.
- Suitable surfactants are anionic surfactants, such as alkylbenzenesulfonates, alkanesulfonates, fatty alcohol sulfates, fatty alcohol ether sulfates, alpha-olefin sulfonates, alpha-ester sulfonates, alkyl phosphates and alkyl ether phosphates, nonionic surfactants such as fatty alcohol ethoxylates, alkylphenol ethoxylates, fatty acid ester ethoxylates, fatty acid ethoxylates, fatty acid ethoxylates, fat surfactants, cationic surfactants, such as quaternary ammonium salts and imidazolinium compounds, in particular alkylammonium compounds, and amphoteric surfactants, such as betaines and sulfobetaines.
- anionic surfactants such as alkylbenzenesulfonates, alkanesulfonates
- Preferred surfactants are those with a pronounced microbiostatic and microbiocidal action, in particular soaps such as sodium palmitate and sodium stearate, core soap, cationic surfactants such as quaternary ammonium salts, in particular those with short alkyl chains, such as dodecyl, dimethyl, benzylammonim chloride, and amphoteric surfactants, such as the 7- C ⁇ 0 -C ⁇ 6 alkyl 3,7-diazaheptanoic acids.
- Very particularly preferred surfactants are 7 -C 6 -C 6 -alkyl-3,7-diazaheptanoic acids and soap.
- the effect of the surfactants as antifungal agents is presumably based on the fact that the surfactants as surface-active agents attach themselves to the cell boundary layers of the fungi and thereby destroy the semipermeability of the cytoplasmic membranes, which mainly consist of lipids and proteins. This prevents the metabolism and thus the fungal growth in a physical way.
- the building materials can be impregnated with the aqueous impregnation solutions according to the invention by all customary methods, for example by brushing, spraying or soaking.
- the aqueous impregnation solutions according to the invention can also be used as wood preservation paints.
- Such an impregnation solution used as wood preservation paint preferably contains 10 to 20% by weight sodium and / or potassium carbonate and 2 to 10% by weight surfactant.
- a low concentration of sodium or potassium carbonate on the wood surface is sufficient for effective flame retardant equipment. This is preferably 20 to 40 g / m 2 of the wood surface.
- the amount of surfactant is preferably 5 to 15 g / m 2 of the wood surface.
- the use of the aqueous impregnation solutions according to the invention as a protective coating for wood is suitable for wooden parts which do not come into contact with water. Otherwise there is a risk that the protective coatings will be washed out. Such protective coatings are therefore particularly suitable for wood protection indoors.
- the aqueous impregnation solutions used according to the invention are preferably used to provide flame and fungus protection for the abovementioned insulation materials.
- Such flame retardant insulation materials generally contain 2 to 10% by weight, preferably 2 to 5% by weight, of sodium and / or potassium carbonate as the flame retardant.
- Insulation materials which are additionally equipped with anti-fungal agents generally additionally contain 0.5 to 3% by weight, preferably 1 to 2% by weight, of surfactant as anti-fungal agent.
- the insulating materials are preferably impregnated with the impregnating solution by spraying or dipping. This can be done, for example, by spraying the insulating materials in a rotary tube dryer and then drying them.
- aqueous impregnation solutions used according to the invention for the flame and fungus protection of plant shives are particularly preferred. especially the cockroach of the Han ⁇ flanze used.
- the previously customary protective layer made of bitumen as a substance that is not harmless to building biology can be dispensed with. By eliminating the protective layer made of bitumen, the thermal insulation capacity of the plant shaving insulation is also improved.
- the flame and fungus protection agents used according to the invention are not toxic to humans. There is also no danger that, in the event of fire, the flame retardants used will decompose to form toxic compounds that can get into the atmosphere or into the ground with the extinguishing water.
- the anti-fungal agents used according to the invention are harmless, also with regard to a later disposal of the building materials.
- the aqueous impregnation solution used according to the invention represents an inexpensive alternative to conventional products.
- Class 0 No mold growth visible at 50x magnification.
- Class 1 Mold growth is not or only with difficulty with the naked eye, but clearly visible under the magnifying glass.
- Class 2 Mold growth is clearly visible to the naked eye, but covers less than 25% of the surface of the test specimen.
- Class 3 Mold growth is clearly visible and covers more than 25% of the surface of the test specimen. The results are summarized in Table 1.
- Spray amount 1.5% by weight based on the weight of the cockroaches
