Abstract

This invention relates to improved adhesion compositions and textile materials and articles treated therewith. The improved adhesion composition comprises a non-crosslinked resorcinol-formaldehyde and/or resorcinol-furfural condensate (or a phenol-formaldehyde condensate that is soluble in water), a rubber latex, and an aldehyde component such as 2-furfuraldehyde. The composition may be applied to textile substrates and used for improving the adhesion between the treated textile substrates and rubber materials. End-use articles that contain the treated textile-rubber composite include, without limitation, automobile tires, belts, and hoses as well as printing blankets.

First claim

I claim:

1. A composition for adhering textile materials and rubber-containing articles comprising:
a) a compound selected from a non-crosslinked resorcinol-formaldehyde condensate, a resorcinol-furfural condensate, a phenol-formaldehyde condensate, and mixtures thereof;
b) a latex component; and
c) an aldehyde component selected from 2,3- and 2,5-thiophenedicarboxaldehyde, 2,5-furfuryldicarboxaldehyde, 1,2-, 1,3- and 1,4-phthalic dicarboxaldehyde, 2,6-pyridinedicarboxaldehyde, 2-, 3- and 4-pyridinecarboxaldehyde, 3-(2-furyl)acrolein, propylaldehyde, butyraldehyde, iso-butylaldehyde, o-sulfo benzoic aldehyde, and compounds of the formula (1), (2) or (3):

wherein
X is O, S or NH, and
R 1 -R 3 each independently are selected from H, alkyl, aryl, halogen, and carboxylic functional groups; and
wherein the weight ratio of compound “a” to aldehyde “c” is from 4:3.2 to 4:4.0.

2. The composition of claim 1 , which further includes a base component.

3. The composition of claim 2 , wherein the base component is selected from sodium hydroxide, potassium hydroxide, ammonium hydroxide, sodium carbonate, and mixtures thereof.

4. The composition of claim 1 , wherein the aldehyde component is selected from 2-
and 3-furfuraldehyde; pyrrole-2-carboxaldehyde; 2- and
3-thiophenecarboxaldehyde; 2,3- and
2,5-thiophenedicarboxaldehyde; 3-(2-furyl)acrolein;
2,5-furfuryldicarboxaldehyde; cinnamic aldehyde; crotonaldehyde; benzyl aldehyde;
propylaldehyde; butyraldehyde; i-butyl-aldehyde; 2-, 3- and 4-pyridinecarboxaldehyde;
2,6-pyridinedicarboxaldehyde, 1,2-, 1,3- and 1,4-phthalic dicarboxaldehyde; o-sulfobenzoic aldehyde and mixtures thereof.

5. The composition of claim 1 , wherein the latex component is selected from epoxy resin, functional rubber latex, elastomer latex having no unsaturated double bonds, unvulcanized rubber latex, and mixtures thereof.

6. The composition of claim 5 , wherein the epoxy resin has an epoxy functionality of ≥3.

7. The composition of claim 5 , wherein the epoxy resin is selected from epoxy cresol-novolac resin, epoxy phenol-novolac resin, poly nuclear phenol-glycidyl ether-derived resin, resin containing an aromatic amine backbone, and mixtures thereof.

8. The composition of claim 5 , wherein the rubber latex is selected from vinylpyridine rubber latex, styrene-butadiene rubber latex, chloroprene rubber latex, nitrile rubber latex, butyl rubber latex, ethylene propylene diene monomer rubber latex, butadiene rubber latex, polyisoprenes, hydrogenated rubber latex, polyurethane and mixtures thereof.

9. The composition of claim 5 , wherein the functionalized rubber latex contains a rubber polymer having at least one pendant carboxyl, amide, or pyridyl group, or a derivative thereof.

10. The composition of claim 5 , wherein the unvulcanized rubber latex is selected from polybutadiene, polyisoprene, synthetic trans-rich polyisoprene or cis-rich polyisoprene, natural rubber, poly(styrene-co-butadiene), poly(acrylonitrile-co-butadiene), chloroprene, hydrogenated styrene-butadiene rubber, hydrogenated nitrile-butadiene rubber, butyl rubber, halo-butyl rubber, ethylene propylene diene monomer rubber and mixtures thereof.

11. The composition of claim 1 , wherein the composition further includes at least one additive selected from hydrophilic solvents, antioxidants, wetting agents, rheology modifiers, pH buffers, heat stabilizers, ozone stabilizers, ultraviolet light stabilizers, emulsifiers, adhesion promoters, antiozonants, carbon black, silica, and mixtures thereof.

12. The composition of claim 1 , which further includes a tacky resin.

13. The composition of claim 12 , wherein the tacky resin is selected from phenol-containing resins, aromatic resins, hydrocarbon resins, terpene resins, indene resins, coumarone resins, rosin-based resins, and mixtures thereof.

14. A coated textile material comprising a textile substrate and a composition comprising the reaction product of claim 1 .

15. A product comprising the coated textile material of claim 14 , which product is selected from a printer's blanket, reinforcing yarns or fabrics used in rubber hoses, reinforcing belting fabrics, V-belts, automotive transmission belts, reinforcing tire cord, tire cap ply, tire body ply, tire bead wrap, tire gum strip, and chafer fabrics.
