Abstract
This invention relates to a method for manufacturing a surface-treated particulate inorganic material, and more particularly to methods for manufacturing lightweight particulate inorganic materials, such as expanded perlite or expanded clay, coated with one or more silsesquioxanes. The surface-treated particulate inorganic material according to the present invention is suited for introduction into construction materials, such as mortar, piaster, cement and lightweight concrete, to lower the loose bulk density and improve the mechanical strength of the mixture.
Claims31
A method for manufacturing a surface-treated particulate inorganic material, the method comprising:
- providing a particulate inorganic material;
- and
- bringing the particulate inorganic material into contact with a composition comprising at least one surface treating agent and thereby obtain a surface-treated particulate inorganic material;
- wherein
- the at least one surface treating agent is an organic-inorganic hybrid polymer;
- the organic-inorganic hybrid polymer being selected from the group of polymers obtainable by a process comprising:
- a) forming a polymer by controlled hydrolysis and condensation of only one type of silane selected from the group of silanes represented by the following general formula:
- (X-L-)nSi(−Y)4−n;
- wherein
- X is —NR1R2, —N=C=O, SH or OH
- R1 and R2 are residues independently selected from the group consisting of hydrogen;
- non-substituted or substituted, saturated or unsaturated C1-C25 hydrocarbon radical;
- and substituted or non-substituted aryl;
- or R1 and R2 are independently selected from the group consisting of condensation products, addition products of one or more type of chemical substances;
- n is 1 or 2;
- L is a direct bond;
- or a residue selected from the group consisting of non-substituted or substituted, saturated or unsaturated C1-C25 hydrocarbon radical;
- and substituted or non-substituted arylene;
- and
- Y is a hydrolysable group or OH;
- and
- b) if X is —NR1R2 and at least one of R1 and R2 is H for the selected silane;
- or X is —N=C=O, SH or OH for the selected silane
- adding at least one reactant capable of forming a covalent bond between an atom of the X group and at least one atom of the reactant;
- the at least one reactant being a compound selected from the group consisting of cyclic anhydride and a compound of formula R-Z,
- wherein
- R is a residue selected from the group consisting of a non-substituted or substituted, saturated or unsaturated C1-C25 hydrocarbon radical which may be straight, branched or cyclic;
- aliphatic or aromatic carbonyl;
- and substituted or non-substituted aryl;
- or a residue selected from the group consisting of condensation products, addition products of one or more type of chemical substances;
- and
- Z is a residue selected from the group consisting of alkoxyl, aryloxyl,cycloalkoxyl, carboxyl, formyl, acyl halide, isocyanate, hydroxyl, amine, epoxide, ester and halogen.
