Definitions
- the invention relates to a method for producing a fire retardant based on homogeneous foam products, after which a glass is reacted with an aqueous alkali metal hydroxide solution at temperatures above 50 ° C and the reaction product discharged as a viscous mass, granulated and cooled until a solid granules is present.
- Homogeneous foam products made of glass and their preparation are described in the generic EP 1 183 215 B1. Thereafter, it is already known to react glasses with an alkali metal hydroxide solution, at elevated temperatures above 50 ° C.
- the reaction product is a homogeneous viscous mass which can be discharged in a plastic state.
- the homogeneous foam products or granules produced in this way can be used inter alia as an insulating material or as a sound absorber and are characterized by their low specific weight and their fire protection effect.
- a generic method for producing a fire retardant based on homogeneous foam products within the scope of the invention is characterized in that the granules having a hydrophobic coating a layer thickness of about 20 microns to 500 .mu.m, in particular 50 .mu.m to 200 .mu.m and preferably 50 microns to 100 microns equipped and incorporated as a fire protection additive in a building material.
- the granules have a grain diameter which is typically in the range of 0.5 to 15 mm, in particular 1 mm to 10 mm and preferably 1 mm to 5 mm. This is usually achieved by the viscous mass discharged, granulated, cooled and optionally crushed and sieved.
- the bulk volume or the bulk density of the solid granules produced according to the invention is from 0.01 to 0.05 g / cm 3 and this bulk volume is maintained even on long timescales of up to one year or even longer by the hydrophobic coating of the stated layer thickness.
- the realized hydrophobic coating of the specified layer thickness of about 20 microns to 500 microns facilitates the incorporation of granules thus equipped in the building material.
- building materials typically polymers and especially plastics are used. Very particularly preferred elastomers are used as building materials, with the help of seals, electrical insulation, electrical cables, cable ducts, etc. are produced.
- the hydrophobic coating of the granules provided according to the invention ensures that the granules can easily be incorporated into such elastomers.
- the invention is based on the finding that, for example, the addition of wax to rubber particles promotes the formation of agglomerates. That is, rubber and wax as a possible hydrophobic coating of the granules are compatible with each other.
- the hydrophobic coating for the granules is added in total in a proportion of 0.5 wt .-% to 2 wt .-%, each based on a starting weight of the foam product.
- the starting weight of the foam product is composed of the basic constituents of the glass used, the alkali metal hydroxide and water as the solvent. Then there is the hydrophobic coating in the specified grammage.
- the invention recommends the use not only of wax, but in principle of silicones, silicone oils, silanols, etc., as long as the hydrophobic and thus water-repellent character is guaranteed to prevent that in the individual In this way, coated granules can penetrate or penetrate water during storage.
- the glasses used are advantageously a recycled glass, a synthetic glass, a mineral glass of natural origin or mixtures of these glasses. Recycled glass is characterized by a high borosilicate content and is therefore also referred to as recycled boron glass.
- the glasses used usually have 60 to 85 wt .-% SiO 2 , 4 to 27 wt .-% Na 2 O, 0 to 5 wt .-% K 2 O, 0 to 8 wt .-% CaO, 0 to 5 wt .-% Al2O3, 0 to 14 wt .-% B 2 O 3 , 0 to 20 wt .-% PbO, 0 to 5 wt .-% MgO and 0 to 8 wt .-% BaO.
- the mixture of the glass and the aqueous alkali metal hydroxide solution is reacted according to the invention at temperatures above 50 ° C.
- the mixture in question is heated to temperatures in the range between about 120 ° C to 250 ° C. This can be done at atmospheric pressure. Alternatively, it is also possible to carry out the reaction described in an autoclave at the indicated temperatures of 120 ° C to 250 ° C and a pressure of 2 to 15 bar.
- hydrophobic materials for example silicones
- the hydrophobic coating is advantageously not water-dilutable silicones.
- the water-dilutable silicones in question can not only be applied as a coating, but can also be incorporated into the interior of the granules.
- the hydrophobic coating is added to the starting materials at the beginning of the preparation.
- the material in question can be added to the water. This is possible even against the background that the hydrophobic coating or the materials used at this point are practically insoluble in water.
- the water / hydrophobic constituent emulsion does not separate and the hydrophobic constituents precipitate as a hydrophobic coating on the individual granules produced and, if appropriate, penetrate into them.
- the hydrophobic coating it is also possible for the hydrophobic coating to be applied to the granules only after the granules have been produced, for example by spraying.
- fillers and / or reinforcing substances can be added to the mixture of the glass and the alkali metal hydroxide solution.
- These fillers and reinforcements are advantageously wollastonite, mica, glass fibers, quartz, talc, zinc oxide, titanium oxide, etc.
- These fillers and reinforcing agents improve the overall compressive strength of the granules produced. In addition, this can for example be set a white color of the granules, to facilitate the subsequent processing in the building material and to make transparent and visible.
- water-dilutable additives such as glycerol and / or ethylene glycol can also be added.
- the residual water content of the granules thus prepared is usually in the range of 20 to 35 wt .-%. Both the mentioned residual water content and the ability of the granules produced from the homogeneous foam products to inflate ensure that the desired fire protection behavior is observed.
- the fire and the associated increased temperatures cause the fire protection additive in the building material in question in the first step emits the trapped water.
- This is usually done in a temperature range up to about 300 ° C.
- the existing water content in the interior of the granules of 20 to 35 wt .-% primarily ensures that the building material is cooled by the resulting water vapor, so the desired fire protection effect is observed.
- Above 300 ° C or after the evaporation of trapped water in the granules then it comes to swelling of these granules, because they are made of the foam products.
- This puffing or frothing is a so-called thermal puffing, which corresponds to an endothermic process.
- the typically above 300 ° C onset of blowing process provides due to its endothermic and thus heat-consuming character in addition to a cooling of the building material and thus the desired fire protection effect.
- a total of the following starting mixture is assumed: about 50 to 60% by weight of glass; about 15 to 20 wt .-% alkali metal hydroxide dry, about 20 to 35 wt .-% water and about 0.5 to 2 wt .-% of the hydrophobic coating.
- the preparation of the fire retardant is generally carried out so that the specified weight of glass, for example 50 to 60 wt .-% recycled boron glass with 18 wt .-% NaOH is mixed dry as alkali metal hydroxide. Then about 30 wt .-% of water are added and the further mixture and reaction takes place at temperatures ranging from 100 ° C to 120 ° C at atmospheric pressure. The reaction is carried out for a total of several minutes, for example 20 minutes. As a result, a homogeneous viscous mass is obtained, which is discharged in a plastic state and pressed, for example, through a perforated disk.
- the specified weight of glass for example 50 to 60 wt .-% recycled boron glass with 18 wt .-% NaOH is mixed dry as alkali metal hydroxide.
- about 30 wt .-% of water are added and the further mixture and reaction takes place at temperatures ranging from 100 ° C to 120 ° C at atmospheric pressure.
- the reaction is carried
- the mass can be comminuted and powdered, for example with quartz powder, in order to avoid possible agglomeration or caking.
- dry and hard granules or granules of the specified grain size between 0.5 mm and 15 mm, in the exemplary embodiment in the range of about 1 mm to 5 mm are observed.
- the grains have the hydrophobic coating in the layer thickness of 50 ⁇ m to 100 ⁇ m. Because the hydrophobic coating in the form of the silicone oil has been added to the water and has formed or precipitated on the granules during the reaction and hardening of the grains as an outer layer.
- the fire retardant prepared in this way is then incorporated into the desired building material.
- This can for example be done so that an elastomer is used as a building material and the granules are filled as an additive in an extruder together with the granules of the building material.
- This comes to the homogeneous distribution of the granules or the fire protection agent inside the output material produced on the extruder desired building material. This may be seals, insulation for cables, cable ducts, etc., as already described in the introduction.
