Definitions
- the invention relates to silicate coatings, especially silicate paints and dispersion silicate paints, comprising at least one basic silicate, at least one filler and / or pigment, water for adjusting a pasty consistency, optionally at least one organic binder and optionally conventional additives.
- Silicate paints are a very important special case of mineral paints. They contain, as is exemplified in detail in Wikipedia, in addition to inorganic colorants as the main component of a potassium-containing alkali metal silicate, also as
- the binding agent water glass is highly resistant to UV influences. While organic binders such as acrylate or silicone resin dispersions embrittle over the years under the influence of UV radiation and lead to chalking phenomena, cracks and, as a consequence, paint damage, the inorganic binding agent water glass remains stable. The chemical bonding with the substrate and the UV stability of the binder are the main reasons for the extremely long life of
- Silicate paints For setting, silicate paints require a mineral, siliceous base. Therefore, they are suitable for mineral substrates such as mineral plasters and concrete.
- Silicate paints are enormously color stable. After they are only tinted with mineral pigments and these do not change in color due to UV light, the silicate coatings also remain constant in color for decades. Basically, three types of silicate paints are historically distinguished, the definitions of which are not intended to limit the invention:
- the pure silicate paint consists of two components, a dry or colorless powder mixed in water and the liquid binder water glass.
- the processing requires a lot of experience and know-how. It is especially popular in the historical area.
- Silicate paints according to the invention can be used in
- Dispossion silicate paints The range of application of this type of silicate paint is significantly greater than that of the pure silicate paint, because even substrates with lower strengths and / or organic proportions can be coated. In addition, the processing is easier than with the pure silicate paint.
- Dispersion silicate paints can contain more than 5% by mass of organic matter
- Additives, in particular binders include. Since 2002, there is a third category of silicate paint, the so-called sol-silicate paint. It contains as a binder a combination of silica sol and water glass. The organic content is limited to 5% by mass, as in the case of the dispersion silicate paint, in order to obtain a chemical setting and the silicate-typical starches.
- the sol silicate paint also allows for use
- silicate and dispersion silicate coatings should (also) be suitable for applications on absorbent, mineral and / or basic, cementitious substrates.
- silicate-bound coatings have clear weaknesses here.
- critical substrates eg absorbent, mineral and / or basic, cementitious substrates
- the silicate-bound coating dries too quickly due to the acceleration of the silicification reaction due to the basicity of the substrate.
- Critical substrates especially basic absorbent substrates, are regularly inhomogeneously critical resp. absorbent. There are places or areas that are more or less critical resp. are sucking. That's why it comes to
- Silicate coatings are available, which allow the spot - free drying on critical substrates, without any pretreatment of the
- silicate coatings should be as easy to process as comparable conventional silicate paints or dispersion silicate paints.
- Disperse silicate paints and other disperse silicate coatings are hydrous, liquid or pasty before their intended use
- Base silicates in the sense of the invention are silicates which on contact with H 2 O due to the presence on the surface of the silicates of at least one
- the "basic silicates” include basic alkali and alkaline earth silicates.
- Basic silicates contain on the surface at least one of the following basic groups or ions:
- Metasilicate - groups or ions
- a coating, composition, paint, plaster and the like in the sense of the invention means both the not yet processed product and the product after its processing.
- silicate paint or “silicate coating” includes the hydrous liquid or pasty coating composition prior to its application, as well as the solid, more or less dry, coating resulting from the application.
- a silicate coating in the sense of the invention comprises a liquid or pasty composition which can be produced from a dry or colorless powder mixed with water and a basic silicate such as, in particular, water glass as a liquid binder, and the additives according to the invention, in particular for delaying the setting, according to the definition in claim 1.
- a dispersion silicate coating in the sense of the invention comprises a one-component silicate coating with organic additives (eg.
- a sol-silicate coating according to the invention is a silicate coating according to the invention or dispersion-silicate coating in the above sense, as defined in claim 1, but contains as binder a combination of silica sol and water glass.
- the organic fraction is as in the case of the dispersion silicate coating according to the invention.
- silicate paints disperse silicate paints, similar silicate-containing compositions (eg, sol-silicate paints, others).
- Coatings as paints and emulsion paints with an addition of basic silicates are collectively referred to as "silicate coatings.”
- “Coating” and “composition” are basically synonymous.
- the invention also includes compositions whose silicate content differs from the usual silicate compositions.
- the invention therefore also encompasses compositions with substantially lower contents of silicates, particularly basic silicates, and substantially higher contents of at least one organic binder compared to conventional (for example the abovementioned) compositions or coatings.
- the content of organic binder can be well over 5 wt.% And outweigh the silicate content, even far outweigh.
- Such compositions correspond
- Dispersion coatings with an addition of basic silicates as an additive are by weight unless otherwise specified.
- the invention solves the problem of staining or streaking when applying silicate coatings to absorbent and / or strongly alkaline substrates basically by delaying the silicification reaction.
- Delay is caused by the addition of a water-soluble carbohydrate to the silicate coating not yet applied.
- the invention therefore relates to silicate coatings, especially silicate paints, comprising at least one basic silicate, at least one filler and / or pigment, at least one water-soluble carbohydrate, water for adjusting a pasty consistency, optionally at least one organic binder and optionally conventional additives.
- silicate coatings or dispersion silicate coatings on purely polymcrgcbundcncn old coatings also leads to adhesion problems, if the substrate is not appropriate
- Embodiments of the coating compositions according to the invention can also be applied without problems to such substrates.
- the basic silicate according to the invention in preferred embodiments of the invention is an alkaline earth silicate, in particular calcium silicate, for example cement, cement clinker, granulated slag and / or hydraulic lime, and / or an alkali metal silicate, for example lithium, sodium or potassium water glass.
- alkaline earth silicate in particular calcium silicate, for example cement, cement clinker, granulated slag and / or hydraulic lime, and / or an alkali metal silicate, for example lithium, sodium or potassium water glass.
- Especially preferred embodiments of the invention contain both alkaline earth silicate and alkali silicate.
- the basic silicate is used in the case of alkaline earth silicates as hydrate-free silicate, i. free or at least substantially free of alkaline earth or calcium silicate hydrate (CSH) phases.
- CSH calcium silicate hydrate
- Hydrate-free calcium silicates are components of cement clinker or of cement.
- cement clinker cement
- cement cement
- cement cement
- cement cement
- cement the fired component of the cement, which is responsible for the curing with the addition of water, and the carrier the basic silicates is.
- Cement is made by grinding cement clinker with Ca sulfates.
- Cement clinker is produced by sintering at high temperatures of limestone, clay (marl) and quartz sand.
- the clinker mainly consists of the following phases:
- Tricalcium silicate (alite), short C3S (3 CaO * Si0 2 ) Dicalcium silicate (Belit), in short C2S (2 CaO * Si0 2 )
- the calcium silicate phases because they cause the strong increase in pH when mixed with water.
- the aluminate phases as well as the CaO are less of interest because they do not react as strongly basic as the hydrate-free silicates. That Cement and clinker with a particularly high content of basic silicates (more C2S phases than C3S phases) are of great importance, since this basic silicate contributes significantly more to the increase in pH than CaO. It is the stronger base.
- the proportion of SiO 2 must not be too high and should be less than 50%, better less than 40%, better still less than 30%. Otherwise, the cement condenses too fast and is difficult to delay. Therefore, not only cement and clinker can serve as a source for the calcium silicate phases, but also slag sands, which are usually from about 30-45% CaO, 30 ⁇ 15% SiO 2, 5-15% A1203, 4-17% MgO , 0.5-1% S and traces of other elements.
- blastfurnace slag Due to the high proportion of SiO2, blastfurnace slag is very well suited, but above all due to the fact that blastfurnace slag is a latent hydraulic binder. Latent means that blastfurnace slag is relatively slow to react and does not set quickly. Since a setting of the hydraulic additive is not desirable, the blastfurnace slag is very well suited. But it is much more expensive than cement / cement clinker.
