Definitions
- the invention relates to clear long-term storage-stable solutions of alkali silicates (water glasses) with an aluminum content of at least 0.5% and to a process for preparing these solutions.
- Glasses are colorless glasses when pure, which form colloidal clear, alkaline solutions with water at elevated temperature and pressure.
- Waterglass is usually made by fusing quartz sand with soda or potash at 1400 to 1500 ° C with the silica expelling the CO2.
- the solidified melt is either marketed in the ground state or converted into an aqueous solution of desired concentration.
- Aqueous solutions have the advantage of better applicability in a number of different application fields.
- Liquid water glass solutions, ie aqueous solutions of alkali metal silicates are industrially made of solid alkali silicate glass pieces by their pressure release in Autoclave made in water.
- sand can also be directly hydrothermally dissolved in concentrated caustic, but only solutions with lower MV can be obtained.
- the object of the present invention was to provide clear aqueous solutions of silicates (water glasses) with an aluminum content of at least 0.5% by weight (wt .-% Al 2 O 3 based on the total aqueous solution of silicate).
- the solutions should be stable in storage for a period of at least 6 months at 20 ° C, ie remain clear during this period and do not gel or lead to precipitation.
- the Applicant has now succeeded in solving the above problem, although the prior art suggests this to be extremely difficult if not practically impossible.
- the invention is first a process for producing clear, at 20 ° C for at least 6 months storage-stable, aqueous solutions of silicates (water glasses) containing
- M 2 O 10 to 20% by weight of M 2 O, where M is a cation from the group Li + , Na + , K + , NY 4 + and Y is an alkyl or alkenyl radical having 1 to 6 C atoms,
- An aluminum compound is metered in such that the viscosity of the reaction mixture remains below 10,000 mPas and the reaction is carried out in a temperature range from 20 to 140 ° C.
- reaction mixture is cooled to room temperature after addition of the total amount of the aluminum compound as soon as the
- the viscosity is measured under reaction conditions and reaction temperature according to ISO 12058-1.
- the reaction is carried out with stirring.
- the Al-containing silicate solutions obtainable by the process according to the invention are preferably adjusted to a viscosity of at least 100 mPas and in particular a viscosity in the range from 100 to 1000 mPas (in this specification, the viscosity of the silicate solutions is in each case meant at 20 ° C.) according to the method according to ISO 12058-1).
- the adjustment of the viscosity is done essentially by the choice of the concentrations of the reactants.
- the process according to the invention guarantees that the resulting aqueous aluminum-containing silicate solutions, despite their high aluminum content, are one-component and clear, do not gel and remain clear and do not form sediment over a period of at least 6 months at 20.degree excellent storage stability means. This is to be regarded as extremely surprising given the described prior art.
- the method according to the invention provides as a critical step, a aqueous solution of a silicate as defined above (water glass) and to meter an aluminum compound such that the viscosity of the reaction mixture remains below 10,000 mPas.
- a aqueous solution of a silicate as defined above water glass
- an aluminum compound such that the viscosity of the reaction mixture remains below 10,000 mPas.
- silicates water glasses
- alkali metal silicates ie those compounds M 2 O x nSiO 2 in which M is a cation from the group Li + , Na + or K + and where n is a number in the range from 1 to 5.
- n is a number in the range from 1 to 5.
- alkali silicates which is an n in the range of 1 to 3 and in particular from 1.6 to 2.8. It is very particularly preferred to use sodium silicate.
- the aluminum source is not critical per se. It is preferable to use ionic aluminum compounds, and particularly inorganic aluminum salts, as an aluminum source (referred to as "aluminum compounds" above), for example, aluminum hydroxide, alumina, sodium alumina or alum.
- Aluminum hydroxide is most preferred as the source of aluminum in the present invention. It can be used on the one hand in solid form, in which case it has to be present in finely divided form and that with a particle size below 1 ⁇ .
- aluminate Solution aluminate Solution
- aluminate solutions with an aluminum content in the range of 10 to 22% are used (% specification means% by weight of Al 2 O 3 based on the entirety of the aqueous aluminate solution).
- the reaction mixture is cooled after addition of the total amount of aluminum compound to room temperature (which is understood here as a temperature range of 5 to 30 ° C and especially 20 to 25 ° C), as soon as the reaction mixture is clear.
- room temperature which is understood here as a temperature range of 5 to 30 ° C and especially 20 to 25 ° C
- turbidity of the reaction mixture generally occurs.
- the time when the reaction mixture becomes clear may depend on the rate of addition of the aluminum source and the reaction temperature. Should it not be at the end of the addition of the aluminum source or shortly thereafter, the reaction mixture is simply further stirred at the previous reaction temperature until it becomes clear, then cooled.
- the aqueous solutions of silicates contain
- Alk is lithium, sodium or potassium
- the aqueous solutions of silicates (water glasses) contain 25 to 35% by weight of SiO 2 ,
- Alk is lithium, sodium or potassium
- the solids content of the novel Al-containing aqueous solutions of silicates is preferably 25-50 wt .-% and in particular 35- 45 wt .-%.
- Another object of the invention are first clear, at 20 ° C for at least 6 months storage-stable, aqueous solutions of silicates (water glasses) containing
- M 2 O 10 to 20% by weight of M 2 O, where M is a cation from the group Li + , Na + , K + , NY 4 + and Y is an alkyl or alkenyl radical having 1 to 6 C atoms,
- An aluminum compound is metered in such that the viscosity of the reaction mixture remains below 10,000 mPas and the reaction is carried out in a temperature range from 20 to 140 ° C.
- reaction mixture is cooled to room temperature after addition of the total amount of aluminum compound
- novel Al-containing silicate solutions can be used in a variety of applications. Examples of these are: fire protection coating, agglomeration aid, Coating agent for pigments, inorganic adhesives.
