Definitions
- Multi-component binders and their use
- the invention relates to multicomponent binders, in particular based on natural substances, and their use, in particular for the treatment and / or processing of natural fibers, according to the preamble of claims 1 and 2 or claims 19, 22, 23 and 24
- natural materials in particular natural fibers, for example for the production of dam materials, rubble dams or blow-in dams, the production of extrudable natural material mixtures, the production of dust-free building material mixtures from unburned clay and / or clay and natural fibers or wood chips, chips, cockroaches and wood fibers, and the additional solidification of natural fibers to prevent the setting behavior of the natural fibers in the installed state is severely restricted by the fact that the natural substances tend to form a lot of dust during processing
- dust binders which are used to bind dust from organic materials, such as wood, coal, food and animal feed.
- Dustole are used here, which are mostly aqueous olemulsions or mixtures of oils and soaps.
- salts such as magnesium chloride are used or calcium chloride used in an aqueous solution as a dust binder, which is sprayed onto the dust-containing substances, as is known from DE 197 33 222 A1
- DE 39 18 523 A1 shows a method for preventing dust formation when loading or transporting granules or pellets, in particular manure granules, a liquid mixture of molasses and glycerol or polyethylene glycol or Triethanolamine in liquid form is sprayed onto the granules to prevent dust formation.
- DE 43 35 167 discloses a molding agent concentrate for the treatment of fabrics and felts, the concentrate containing 10-35% by weight of water-soluble vegetable resin, 60-85% by weight of water, 2-8% by weight of borax, 1-5% by weight of Seignette salt and 0 , 2-3% by weight of Glycenn.
- the known concentrate cannot be used for the intended use in the case of natural substances, namely their processing into sheets, molded parts, extrudates and nonwovens.
- the invention is therefore based on the object of providing multicomponent binders which enable the above-mentioned processing of the natural products without substantial dust formation.
- the invention is also based on the object of finding suitable uses of such multicomponent binders.
- the multicomponent binder according to the invention comprises:
- inorganic salts 0.1-8% by weight one or more inorganic salts with the proviso that the inorganic salt is not a borax, 0-5% by weight one or more salts of a dicarboxylic acid,
- hydrophilic diluents 60-99.8% by weight of one or more hydrophilic diluents.
- the multicomponent binder according to the invention comprises:
- the adhesive content is non-zero
- hydrophilic polysaccharides are preferably water-soluble
- the addition of a filler up to three times the amount by weight based on the natural material to be bound increases the strength significantly
- the composition is preferably adjusted to a pH in a basic range, in particular to a pH in the range from 7 to 12.
- the content of adhesive is preferably 2-15% by weight. More preferably, the content of water-soluble polysaccharide is 1-15 wt%
- Ammonia, amine or an alkali hydroxide is preferably used to adjust the pH range, with the binder in particular being adjusted to a pH in the range from 8 to 11 if any aluminum hydroxide which has precipitated is to be dissolved
- the adhesive is preferably selected from the group consisting of plastic glue, cellulose glue, natural proteins and starch.
- plastic glue this can be polyester and polyurethane.
- the glue is a natural protein, it is particularly selected from the group consisting of grain glue, such as gluten and Zein, and chemically modified protein like casein glue
- the polysaccharide is preferably selected from the group consisting of gum arabic, tragacanth, guar and organically modified polysaccharide such as methylhydroxypropyl cellulose.
- the inorganic salt is preferably selected from the group consisting of NaBO2, NaBO3, Na2B4O7 borax, NaAI (S04) 2 alum, KAI (S04) 2, AI2 (S04) 3, AICI3, acetic acid clay and Na3P04.
- the dicarboxylic acid is preferably selected from the group consisting of oxalic acid, tartaric acid and citric acid
- the polyglycol is preferably selected from the group consisting of glycine, propylene glycol and diethylene glycol
- the hydrophilic diluent is water
- the binder can have a preservative and / or fungicide and / or insecticide.
- the binder can have a flame retardant and / or a hydrophobic agent and / or a water wetting agent
- One use of the multicomponent binder according to the invention then consists in that the binder is used to prevent dust formation when processing natural products, the multicomponent binder being added to the natural products
- the binder is used in a process for producing dimensionally stable molded parts from natural products or natural product mixtures as organic dam materials under the action of pressure and / or temperature, the binder being added to the natural products or natural product mixtures Molded parts made from natural substances or their mixtures as organic dam materials under the influence of temperature, it is advisable to use a filler for solidification.
- a filler for solidification.
- clay, silt, rock or cereal powder or mixtures thereof are suitable as fillers
- the binder is used in a process for the production of extrudates from natural products or natural product mixtures, the binder being added to the natural products or natural product mixtures before the extrusion
- Another preferred use of the multicomponent binder consists in a process for producing nonwovens from natural substances or mixtures of natural substances Use of the multicomponent binder, the binder being added to the natural products or natural product mixtures
- natural substances are preferably understood to mean natural fibers, wood chips, wood chips, chopped rock or rice straw, chopped Chinese reed (Miscanthus) clay, clay or mixtures thereof
- Multi-component binders based on gum arabic 9% gum arabic 2% Kahumborat 3% potassium nat ⁇ umtatrat 3% diethylene glycol 0.5%
- a sound and heat insulation board can be produced as follows:
- 1 kg of chopped straw is intimately mixed with a slurry of: 1 kg of water, 1 kg of binder as above, 2 kg of flour or clay or rock flour and 100 g of flame retardant.
- Drying the slurry formed into a board results in a sound and heat insulation board
