Abstract

The invention relates to a new binder composition which is particularly suitable for the manufacture of composite materials utilizing such new binder composition in the required nonwoven materials. Composite materials using such new binder composition in their nonwoven part are suitable, in particular, for composites materials for interior construction, for linings, floor coverings, and for the manufacture of furniture and similar products.

First claim

The invention claimed is:

1. A semi-finished product comprising:
a textile structure; and
a binder, wherein the binder is made from a binder composition comprising:
a B-stage binder composition comprising a B-stage thermoset polymer, and
a polyolefin emulsion,
wherein the semi-finished product can undergo further hardening of the binder to form a final product.

2. The semi-finished product of claim 1 , wherein the textile structure comprises at least one fiber selected from the group consisting of natural fibers, fibers of synthesized polymers, fibers of natural polymers, ceramic fibers, mineral fibers, and glass fibers.

3. The semi-finished product of claim 1 , wherein the textile structure comprises at least one material selected from the group consisting of a tissue, layer, multiaxial fabric, knitted fabric, woven fabric, non-woven fabric, and paper.

4. The semi-finished product of claim 1 , wherein the B-stage binder composition comprises a formaldehyde-free binder composition.

5. The semi-finished product of claim 1 , wherein the B-stage binder composition comprises at least one binder composition selected from the group consisting of furfuryl alcohol formaldehyde, phenol formaldehyde, melamine formaldehyde, and urea formaldehyde.

6. The semi-finished product of claim 1 , wherein the thermoplastic polyolefin emulsion comprises polypropylene.

7. The semi-finished product of claim 1 , wherein the thermoplastic polyolefin emulsion is 0.1 wt. % to 35 wt. % based on a total solids content of the binder composition.

8. The semi-finished product of claim 1 , wherein the thermoplastic polyolefin emulsion does not have three-dimensional crosslinking.

9. The semi-finished product of claim 1 , wherein the binder composition further comprises a hardening catalyst for the B-stage binder composition.

10. The semi-finished product of claim 9 , wherein the hardening catalyst is selected from the group consisting of ammonium nitrate, p-toluene sulfonic acid, and maleic acid.

11. The semi-finished binder product of claim 9 , wherein the hardening catalyst comprises 0.25 wt. % to 7 wt. % relative to the total binder content.

12. The semi-finished binder product of claim 1 , wherein the binder is 10 wt. % to 30 wt. % of a weight of the textile structure.

13. The semi-finished binder product of claim 1 , wherein the semi-finished binder product further comprises at least one functional material selected from the group consisting of a flame proofing agent, a material to discharge electrostatic charge, a material to screen off electromagnetic rays, a filler, a pigment, a material to increase resistance to wear, a material to increase resistance to slippage, and a decorative element.

14. A semi-finished binder product comprising:
a textile fabric comprising glass fibers; and
a partially-cured binder,
wherein the partially-cured binder comprises a partially-polymerized thermoset polymer and a thermoplastic polymer emulsion selected from polyolefins and polyurethanes, and wherein the thermoplastic polymer emulsion does not have three-dimensional crosslinking.

15. The semi-finished binder product of claim 14 , wherein the glass fibers are selected from the group consisting of A-glass, C-glass, E-glass, S-glass, T-glass, and R-glass.

16. The semi-finished binder product of claim 14 , wherein the partially-polymerized thermoset polymer comprises a formaldehyde-free polymer.

17. The semi-finished binder product of claim 14 , wherein the partially-polymerized thermoset polymer is selected from the group consisting of furfuryl alcohol formaldehyde, phenol formaldehyde, melamine formaldehyde, and urea formaldehyde.

18. The semi-finished binder product of claim 14 , wherein the thermoplastic polymer emulsion comprises polypropylene.

19. The semi-finished binder product of claim 14 , wherein the partially-cured binder further comprises a hardening catalyst for the partially-polymerized thermoset polymer, and wherein the hardening catalyst is selected from the group consisting of ammonium nitrate, p-toluene sulfonic acid, and maleic acid.

20. The semi-finished binder product of claim 14 , wherein the semi-finished binder product further comprises at least one functional material selected from the group consisting of a flame proofing agent, a material to discharge electrostatic charge, a material to screen off electromagnetic rays, a filler, a pigment, a material to increase resistance to wear, a material to increase resistance to slippage, and a decorative element.

21. A semi-finished binder product comprising:
a textile structure; and
a B-stage binder,
wherein the B-stage binder comprises a B-stage thermoset polymer, and a polyolefin polymer derived from a polyolefin emulsion that does not have three-dimensional crosslinking.

22. The semi-finished product of claim 21 , wherein the textile structure comprises at least one fiber selected from the group consisting of natural fibers, fibers of synthesized polymers, fibers of natural polymers, ceramic fibers, mineral fibers, and glass fibers.

23. The semi-finished product of claim 21 , wherein the B-stage thermoset polymer comprises a formaldehyde-free polymer.

24. The semi-finished product of claim 21 , wherein the B-stage thermoset polymer is selected from the group consisting of furfuryl alcohol formaldehyde, phenol formaldehyde, melamine formaldehyde, and urea formaldehyde.

25. The semi-finished product of claim 21 , wherein the polyolefin polymer comprises a polypropylene polymer.
