Definitions
- the invention relates to a methylmethacrylate-free mixture for preserving porous substances, in particular objects made of stone or wood. Furthermore, the invention relates to a method for preserving porous substances.
- TEOS tetraethoxysilane
- KSE silica ester
- the object of the invention is to produce a resistant protective layer in the pore system against the attack of water and pollutants in porous materials, in particular bodies and at the same time build up missing binder in the pore system.
- the mixture contains at least two substances from the group of organically modified silicas, in particular organo (alkoxy) silanes (Ormosile).
- the substance mixtures have a very good penetration behavior due to their molecular size and are able to achieve even very small pores.
- these mixtures harden by hydrolysis and polycondensation, so that a solids content between 4% up to 69%, in particular between 8% to 30% remains as a film lining the pore walls in the pore space.
- the curing which takes place by means of hydrolysis and polycondensation is surprisingly easy to control, in particular in the case of large-volume objects, by means of a program-controlled temperature and moisture control.
- the resulting silica in the pore space verifiably covers the pore walls as a crack-free, transparent, water-insoluble film with good adhesion, so that the hoped-for lining effect of the pore occurs.
- the required water can be added just before the impregnation, without affecting the penetration in the required penetration more negative.
- a coupling agent in particular an organosilane. It is also important that a liquid acrylate-free mixture is achieved.
- the liquid composition according to the invention is used for the preservative impregnation of porous substances, in particular of objects made of wood or stone.
- the two components of the active ingredient system consisting of glycidyl-propyltrimethoxysilane (GLYMO) and aminopropyltriethoxysilane (APTS) in alcoholic solution are combined in stoichiometric amounts before injection into the pore system of the substance to be preserved and react with elimination of water to form an intermediate with six alkoxigram groups.
- Partial hydrolysis activates the active substance system and condenses, with elimination of water and alcohol, to form a silica gel, in whose structure the organic component is bound between Si atoms, and acts as a spacer to build up a low-stress gel structure (Figure).
- the preserving liquid may be composed differently, wherein the mixture contains at least one substance from the group of organo (alkosy) silanes (Ormosile).
- the following mixtures are particularly advantageous:
- a substance of the mixture is an Ormosil containing at least one epoxide unit.
- One substance of the mixture is a 3-glycidyloxypropyltrimethoxysilane (GLYMO).
- GLYMO 3-glycidyloxypropyltrimethoxysilane
- a substance of the mixture is an Ormosil containing at least one amine function.
- One substance of this mixture is a gammaaminopropyltriethoxysilane (APTS).
- APTS gammaaminopropyltriethoxysilane
- alcohol having one to six carbon atoms especially ethanol or methanol, is added.
- the mass ratio of the Ormosil containing at least one epoxide moiety to the Ormosil containing at least one amine function is 1: 0.2 to 1:10, preferably 1: 0.7 to 1: 1, 7, and more preferably a mass ratio of 1 : 1, 07 on.
- the porous substance in the form of an object eg. As a stone or a piece of wood, is first dried and then immersed in a liquid which consists of at least two Ormosilen plus a solvent liquid preferably ethanol.
- a liquid which consists of at least two Ormosilen plus a solvent liquid preferably ethanol.
- the mass ratio of the Ormosil, which contains at least one epoxide unit to the Ormosil, which contains at least one amine function 1: 1, 07th
- An advantageous mixture consists of 2.4 g Ormosil 1, 2.3 g Ormosil 2 and 28 g ethanol. In the case of 28 g of ethanol, a solids separation of approx. 9.5 - approx. 10% is achieved in the object.
- the proportion of ethanol can be chosen here between 0 - 5O g.
