Abstract

The invention relates to a continuous method for producing a cross-linked unsaturated fatty acid-based or fatty acid ester-based bonding agent, an elastic bonding agent produced according to said method and the use of said elastic bonding agent.

Claims

1. A continuous process for producing a cross-linked binding agent comprising:

foaming with oxygen a mixture containing unsaturated fatty acids and/or fatty acid esters;

pressurizing the mixture; and

,

reacting the mixture by oxidizing and cross-linking to form the cross-linked binding agent.

2. The process of claim 1, wherein a foam with a weight of 80 to 800 grams per liter is produced during foaming.

3. The process of claim 1, further including continuously tempering the mixture before reacting.

4. The process of claim 1, further including interrupting reacting the mixture using water.

5. The process of claim 1, further including setting mixture pressure at about 0.1 to about 15 MPa and oxygen pressure between about 0.15 and about 5.6 MPa prior to foaming.

6. The process of claim 1, wherein reacting of the mixture is carried out in emulsion.

7. The process of claim 1, further including melting a resin into the mixture during reacting when the mixture has attained a viscosity of between about 50 and about 100,000 mPas.

8. The process of claim 7, wherein the resin is selected from copal resin, balsam resin, hydrocarbon resin, hydrated resin and combinations thereof.

9. The process of claim 1, wherein the mixture includes an oil selected from drying oils, semi-drying oils and combinations thereof.

10. The process of claim 1, further including adding a surface interactive agent to the mixture.

11. The process of claim 1 further including adding to the mixture an agent selected from drying agents, combination drying agents, adjuvants and combinations thereof.

12. The process of claim 1, wherein foaming and reacting the mixture are carried out as a cyclical process.

13. The process of claim 1, further including boiling the mixture after reacting.

14. The process of claim 13, wherein boiling includes continuously compressing the mixture.

15. The process of claim 13, further including adding organic peroxides to the mixture prior to boiling.

16. The process of claim 15, further including:

heating the mixture; and

, compressing the mixture.

17. An elastic binding agent formed according to the process of claim 1.

18. The elastic binding agent of claim 17, wherein the elastic binding agent exhibits an MFI melting index of between about 0.02 and about 25 ml/24s at a temperature of about 60°

C.

19. The elastic binding agent of claim 17, wherein the elastic binding agent exhibits a complex modulus of transverse elasticity between about 1 and about 250 kPa.

20. The elastic binding agent of claim 17, wherein the elastic binding agent exhibits a loss factor of between about 0.1 and about 30, at an oscillating deformation of y=0.09657.

21. A plastic replacement product including the elastic binding agent of claim 17.

22. A linoleum surface structure comprising the elastic binding agent claim 17.

23. The continuous process of claim 1, wherein the oxygen is contained within a gaseous mixture.

24. The process of claim 16, wherein the organic peroxides are stabilized during heating.

25. The process of claim 1, wherein partial cross-linking occurs during heating.

26. The process of claim 1, wherein peroxide-initiated cross-linking occurs during compressing.
