  • the invention is also related to an improved adhesive product.
  • the invention is related to methods for preparation of the composite product and the adhesive product.
  • Prior known particle boards and plywood boards contain resin as binding agent, which is harmful for the environment.
  • the problem with those is that different harmful gases, for example formaldehyde, are spread from them to the indoor air of the building.
  • Water glass is an environmentally friendly substance, which is known from other connections. Its water resistance is, however, not especially good and therefore there are certain problems related to its use.
  • a known technique that improves the water resistance of water glass is addition of pigments and metal salts. Heat treatment combined with washing with acids has also been tried, as well as glyoxal treatment (Kirk Othmer (1997), vol. 22, p. 23). However, the strength and endurance of such products has not been sufficiently good.
  • a further problem related to the prior art fibre products is their poor or lacking fire resistance. This problem relates to both board products and other, 3-dimensional composite products made of fibre.
  • the object of the invention is to obtain a composite product, with which said disadvantages of prior art products are avoided or reduced.
  • the object of the invention is to achieve a composite product, such as a board product or a fibre product with 3-dimentional form, which is fire resistant, sufficiently strong and manufactured of pure natural materials, which do not contain substances that are harmful for the environment or humans.
  • the invention is based on a discovery that water glass and mineral substance, such as graphite, together give good water resistance and fire resistance for a composite product comprising fibres.
  • the invention is further based on a discovery that a good adhesion and impregnation of the fibres is achieved by further using solvent, such as dimethyl sulphoxide in the production of the composite product, whereby good strength and endurance of the composite product is achieved.
  • the composite product of the invention consists of fibre material, a cohesive binding agent and additives, and it is characterized in that water glass is used as binding agent and in that the product comprises mineral substance, preferably graphite, as a substance that increases fire and water resistance, and that the product also comprises solvent, such as dimethyl sulfoxide.

  • the invention is also very suitable for the production of composite products of other, 3-dimensional forms.
  • Examples of such products are car parts, such as buffers and dashboards, which can thus be made of natural, harmless materials, and still it is possible to achieve very high strength and endurance for the product.
  • the composite products may also comprise flax or hemp as the fibre material. The behaviour of such products are also safer in e.g. car components because no sharp projections are formed in a car collision.
  • fibre material and graphite are used, which are mixed well with each other.
  • Wallpaper glue or wood adhesive is added in this mixture if such glue is used after which the mixture is mixed again, and water glass is added as dry material, after which the mixture is mixed again.

  • the compression temperature is preferably 180° - 200 0 C and the compression pressure is ca 32 bar, with which the desired density is achieved.
  • the compression temperature can be substantially reduced by adding zinc oxide into the product.
  • the wood material used for preparing a particle board can be e.g. ca 70 - 90 vol. -% saw dust or chips, 3-10 vol. -% water glass as dry material, preferably 8 - 9 vol.-%, 2,5 - 14 vol. -% graphite, preferably 5,5 vol.-%, 2-6 vol.-% wall paper glue or wood adhesive, and 5-15% solvent, such as dimethyl sulfoxide, DMSO, which is biologically degradable.
  • DMSO dimethyl sulfoxide
  • Graphite and water glass are non-flammable natural materials, which are harmless for humans and the nature. Furthermore, water glass hinders decay and moulding, so thanks to such a fire resistant material, other wood preservatives and mould preservatives are no more necessarily needed.
  • Gypsum can also be used in the invention as a fire resistant material. This at the same time increases the rigidity and strength of the product. In addition, the price of a fire resistant material containing such a substance is economic.

If dry water glass is used, the amount of it is ca 2-10 vol. -%.
  • zinc oxide improves the drying of water glass, and thus lower processing temperatures can be used. Zinc oxide also improves the water resistance of the product.
  • the water resistance of water glass can in the invention especially advantageously be improved by adding to the composition a little amount of calcium sulphate (gypsum) or lithium carbonate or lithium chloride or titanium sulphate.
  • gypsum calcium sulphate
  • titanium oxide TiU 2
  • the additions of salts have to be done so that the water glass is as homogeneous as possible after the additions.
  • the homogenisation can be improved by means of rigorous agitation and grinding as well as heating. Also a little particle size of the additive improves the homogenBation.
  • the formulation, with which the board is done can contain a little amount of additives that improve the water resistance (0,01-5 %), such as lithium salts and/or lithium compounds, titanium salts and/or titanium compounds, calcium salts and/or calcium compounds and other corresponding additives.
  • wax preferably dry natural wax in the product. This further improves the water/moisture resistance of the product.
  • an adhesive product has same advantages as the composite product; good water resistance, fire resistance, strength and endurance.
  • Such an adhesive product is not harmful to the environment or humans, as the components of the product are natural/biodegradable materials.
  • the adhesive product can be made with same mutual proportions of water glass, mineral substance, such as graphite, and solvent, such as dimethyl sulfoxide DMSO, possible wallpaper glue or wood adhesive as the composite product, except that the adhesive product itself does not comprise fibres as its main component.
  • Same additives can be used in the adhesive product as in the composite product. Also, the function of each component is similar as described in relation to the composite product.
  • Particle boards were prepared at VTT (Technical Research Centre of Finland) of surface and middle-layer particles delivered by Koskinen Oy for use in the preparation of particle boards.
  • the glue material used was according to the following formulation, a mixture of water glass (Huber Engineered Materials, sodium silicate Zeopol ® 22), graphite powder (delivered by the inventor) and wallpaper glue (bought from a store):
  • wall paper glue also means wood adhesives, which have same properties as the wall paper glue in comparison.
  • the dry matter of the wallpaper glue (4 grams of carboxyl methyl cellulose) was added directly to the sodium silicate without preparing any water solution.
  • the boards are marked with numbers 12 and 13 in the result table.
  • the wallpaper glue was left out from the formulation and two different water glass/graphite amounts were tested in relation to the particles.
  • the boards were pressed to a goal thickness of 12 mm and the calculated density was 680kg/m 3 . A low density automatically decreases the IB-value. Boards 4 and 5 were close to the goal thickness and also the best IB-results were achieved with board numbers 4 and 5, which were pressed in 80 0 C and which had a cooling step of 10 minutes and which had been made with formulations 1 and 2.
  • the water resistance of the boards was tried to improve by using as additive, in formulation 4, 1 % TiO2 and LJ2C03 of weight of water glass.
  • the additive in formulation 6 was gypsum (CaS04) which is a by-product of chemical producer Kemira Oyj. All these substances inproved the water resistance of the board.
  • a high temperature improves the water resistance of water glass, why a separate heat treatment was tried for one of the samples.
  • a new test piece was taken from the earlier prepared test board 5, which was kept in 200 0 C in an oven for one hour. The swelling was tested from the test piece after the heat treatment. The swelling was only 4,6 %.
  • the heat treatment improved the swelling result of a board that earlier did not stand water so that the swelling after the heat treatment was only 4,6 %. This result has to be considered to be very good.
  • Such a conclusion should either not be drawn from the results that the heathg would affect the IB-va ⁇ e in a worsening manner as the heat treated samples are located in the middle of the board and had already been used earlier.
  • the swelling can be considerably improved with the heat treatment (200 0 C, 1 h)
  • the mixture was thorough ⁇ mixed for ca ten minutes until a composition with a solid and uniform mass was obtained and from which a cohesive board could be prepared.
  • the mass was then placed in a form for preparation of a board. Baking paper was placed at the upper and lower surfaces of the board to avoid adhesion and the mass was compressed by pressing.
  • the form was thereafter placed in an electric oven for 15 minutes in a temperature of 200 0 C. Thereafter, it was taken out from the oven and dried to a final dryness.
  • the board hardened and the result was a cohesive board.
  • the dry-materials are first mixed together. It is important that the cutter chips and the graphite are mixed well and that the graphite does not stay at the bottom of the vessel. Then the wallpaper glue is added and mixing is performed again. The water glass dry matter is added next, and mixing is performed again. Water is added last, with which the rigidity of the mixture can be regulated. The mixture is poured in a form in which it is compressed to the desired density. Baking paper has to be put between the press jaws or the like so that the mass would not fasten to the jaws. The compression temperature has to be 180-200 °C so that the dry water glass would melt.
  • a particle board was prepared from the following composition in the same way.
  • Particle boards were prepared with the following formulation:
  • the samples were kept in a space with a temperature of 23°C and the relative humidity was 50 %. According to the follow-up of the weight of the samples, the samples reached a constanthumidity during the conditioning.
  • the heat development of board 5 is in the beginning of the test a little lower than the0 heat development of a corresponding wood sample without any fire protection used as reference sample. From this it can be concluded that the sample wood be classified in the same way as the reference sample. Thus, the fire technical behaviour of building tools in accordance with the heat development of classification [1] would probably be D. 5 On the basis of the results, the heat development of board 4 is better than that of board 5.
  • the smoke formation speed of boards 4 and 5 does not deviate so much with respect of classification from the smoke formation speed of the reference sample.
  • the tests were repeated using approx. 10% dimethyl sulfoxide DMSO as solvent and 1-3% zinc oxide as additive in producing the products of the above examples.
  • the solvent substantially improves the absorption of the product components and additives into the fibre material. As a result the strength and water resistance of the composite product is much improved while the good fire resistance properties are maintained.
  • Zinc oxide causes the water glass to dry in a lower temperature, and thus a temperature as low as 80-100 0 C could be used. Water resistance was also increased when zinc oxide was added. The water/moisture resistance could also be increased by adding 1 % of dry natural wax in the product.
  • graphite has been mentioned as one mineral substance to be used as a mineral component of the product, also other alternatives exist.
  • other form of carbon can be used as a mineral substance instead of graphite.
