Definitions
- the invention relates to a composition for hydrophobing, preferably for mass hydrophobization of mineral building materials, in particular mineral and / or alkaline earth metal-containing and substantially non-silicate building materials, comprising at least one water-soluble amino- and alkyl-functional co-condensate siloxane and a bis ( alkoxysilyl) amine and its hydrolysis products, a process for the preparation of this composition and the use of the composition for the mass hydrophobization of preferably gypsum.
- Gypsum is used under various conditions of use as a construction and material.
- the person skilled in the art knows that gypsum is calcium sulfate, which is present in various forms
- Hydration levels may be present. Due to the easy drainability (dehydration) of, for example, naturally occurring or obtained from industrial processes, CaSO 4 » 2H 2 O, it has a diverse range of applications.
- Dehydrated gypsum anhydrite or hemihydrate obtains a more or less high strength by adding water to form a crystalline structure and can then be used as a building material.
- Gypsum products such as gypsum boards and gypsum fibreboards are often made by premixing gypsum anhydrite or hemihydrate in water and spreading the resulting slurry over large areas
- gypsum In humid rooms or outdoor applications, however, the use of gypsum as a building material is limited, since even set gypsum has a certain solubility in water and would dissolve when soaked. Water-repellent (hydrophobic) plasterboards and elements are therefore used. Particularly desirable and economical is the hydrophobing of gypsum elements in the mass (Massenhydrophobitation) already during production. It is advantageously possible to provide the aqueous gypsum slurry with an additive which gives the set material the hydrophobic properties. This is advantageously an aqueous system or a water-soluble or dispersible system which can be added to the dehydrated gypsum anhydrite or hemihydrate together with the mixing water.
- EP 1 1 12986 and US 2006/0107876 each disclose processes for producing water-repellent plasters in which silanes and / or siloxanes and at least one additional catalyst are added to a gypsum mixture.
- US 2006/0107876 discloses the use of a glycol-functionalized siloxane in the presence of alkali metal hydroxides.
- EP 1 1 12986 relates to
- GB 2433497 discloses hydrophobized gypsum mixtures obtained by adding the powdered gypsum to a hydrolyzable organosilane, water and a catalyst whereby the organosilane is hydrolyzed only in the presence of the gypsum. For this purpose it is recommended to add the catalyst to the monomeric organosilanes only immediately before the addition of the stucco. Disadvantage of the mixtures described is the VOC content of the alkoxy silanes preferably used.
- EP 0 819 663 B1 discloses a gypsum mixture in which a physical mixture of a lower alkyl group-substituted silane and a trialkoxysilane substituted with amino groups, amino-lower alkylamino groups or dialkylenetriamine groups are uniformly dispersed.
- the possible weight ratios of the two silanes are 1: 1 to 9: 1.
- the entire aqueous gypsum mixture is VOC-containing and still contains the entire hydrolysis of the two silanes. The disadvantage of this VOC content in the industrial production of
- EP 0796826 discloses hydrophobic gypsum mixtures which, in addition to the silane mixtures described in EP 0819663, also contain polysiloxanes. These are H-substituted polysiloxanes, with the disadvantages explained above.
- WO 2007/009935 discloses a process in which the VOC content of the hydrophobing components is lowered by preparing a precondensate before the resulting siloxane is added to the gypsum mixture.
- a disadvantage in turn is the necessity of adding a second catalyst to the gypsum mixture. If this second catalyst is dispensed with, the achievable water-repellent effect is not reliably given sufficiently strong.
- the object of the present invention is therefore to provide a composition and a process which provides the hydrophobing of
