Abstract

A multi-component composition comprising a first component including water, and a second component including at least one hydraulic binder, wherein the multi-component composition includes a copolymer CP, wherein the copolymer is a vinyl versatate copolymer CPA, and/or a copolymer based on styrene and (meth) acrylic acid esters CPB. The amount of hydraulic binder, based on the total weight of the multi-component composition, is from 25-65 weight-%. The multi-component composition is especially suitable as a flooring material for industrial floors and car parks.

First claim

The invention claimed is:

1. A multi-component composition comprising
a first component (A) comprising water, and
a second component (B) comprising at least one hydraulic binder,
wherein:
the multi-component composition comprises a copolymer CP in an amount in a range of 2.5-7 weight-% based on a total weight of the multi-component composition,
the copolymer is a vinyl versatate copolymer CPA, and/or a copolymer based on styrene and (meth) acrylic acid esters CPB,
an amount of the at least one hydraulic binder, based on the total weight of the multi-component composition, is in a range from 40-60 weight-%, and
a weight ratio of the water to the at least one hydraulic binder is in a range of 0.30 to 0.65.

2. The multi-component composition according to claim 1 , wherein the vinyl versatate copolymer CPA is selected from the group consisting of ethylene-vinyl acetate-vinyl versatate copolymer, vinyl acetate-vinyl versatate copolymer, vinyl acetate-vinyl versatate-(meth)acrylic acid ester copolymer and vinyl acetate-vinyl versatate-(meth)acrylic acid ester-ethylene copolymer.

3. The multi-component composition according to claim 1 , wherein the copolymer based on styrene and (meth) acrylic acid esters CPB is based on two or more monomers selected from the group consisting of styrene, (meth) acrylic acid, C 1 -C 7 alkyl-(meth) acrylate, and (meth) acrylamide.

4. The multi-component composition according to claim 1 , further comprising one or more aggregates.

5. The multi-component composition according to claim 1 , further comprising calcium carbonate.

6. The multi-component composition according to claim 5 , wherein the amount of calcium carbonate, based on the total weight of the multi-component composition, is in a range from 2.5-10 weight-%.

7. The multi-component composition according to claim 1 , further comprising flint.

8. The multi-component composition according to claim 7 , wherein the amount of flint, based on the total weight of the multi-component composition, is in a range from 20-55 weight-%.

9. The multi-component composition according to claim 1 , further comprising calcium carbonate in an amount in a range of 3.5-9 weight-% based on the total weight of the multi-component composition.

10. The multi-component composition according to claim 1 , further comprising calcium carbonate in an amount in a range of 4-8 weight-% based on the total weight of the multi-component composition.

11. The multi-component composition according to claim 1 , wherein the multi-component composition is a flooring composition, a coating composition or a grout composition.

12. A multi-component composition comprising
a first component (A) comprising water, and
a second component (B) comprising at least one hydraulic binder,
wherein:
the multi-component composition comprises a copolymer CP in an amount in a range of 2.5-7 weight-% based on a total weight of the multi-component composition,
the copolymer CP is a copolymer based on styrene and (meth) acrylic acid esters CPB,
an amount of the at least one hydraulic binder, based on the total weight of the multi-component composition, is in a range from 25-65 weight-%, and
a weight ratio of the water to the at least one hydraulic binder is in a range of 0.30 to 0.65.

13. The multi-component composition according to claim 12 , wherein the amount of the at least one hydraulic binder, based on the total weight of the multi-component composition, is in a range from 40-60 weight-%.

14. The multi-component composition according to claim 12 , wherein the copolymer based on styrene and (meth) acrylic acid esters CPB is based on two or more monomers selected from the group consisting of styrene, (meth) acrylic acid, C 1 -C 7 alkyl-(meth) acrylate, and (meth) acrylamide.

15. The multi-component composition according to claim 12 , further comprising one or more aggregates.

16. The multi-component composition according to claim 12 , further comprising calcium carbonate.

17. The multi-component composition according to claim 16 , wherein the amount of calcium carbonate, based on the total weight of the multi-component composition, is in a range from 2.5-10 weight-%.

18. The multi-component composition according to claim 12 , further comprising flint, wherein the amount of flint, based on the total weight of the multi-component composition, is in a range from 20-55 weight-%.

19. A method for the manufacture of a flooring or coating with the multi-component composition according to claim 1 , the method comprising:
a) mixing the first component (A) and the second component (B),
b) applying the mixed material to a substrate,
c) optionally smoothing the applied mixed material, and
d) curing the applied mixed material, to obtain the flooring or coating.

20. A flooring or coating, manufactured by the method of claim 19 .
