Abstract

The present application provides heat-curing preparations containing (a) a triglyceride fraction, the fatty acid distribution of which has a proportion of at least 5 wt. %, in particular at least 60 wt. %, of one or more Ω-3 fatty acids and/or one or more Ω-6 fatty acids, (b) at least one vulcanizing agent selected from the group consisting of (b1) sulfur, (b2) peroxidic vulcanizing agents, (b3) quinones and/or quinone dioximes and/or (b4) dinitrosobenzenes, and (c) at least one inorganic filler.

First claim

What is claimed is:

1. A hot-curing preparation containing
(a) a triglyceride fraction, the fatty acid distribution of which has a proportion of at least 5 wt. % of one or more Ω-3 fatty acids and/or one or more Ω-6 fatty acids,
(b) at least one vulcanizing agent selected from the group consisting of
(b1) sulfur,
(b2) peroxidic vulcanizing agents,
(b3) quinones and/or quinone dioximes and/or
(b4) dinitrosobenzenes,

(c) at least one inorganic filler, and
(d) at least one synthetic polymer having at least one C═C double bond and/or at least one C≡C triple bond;
wherein the triglyceride fraction has a fatty acid distribution having a proportion of at least 15 wt. % of one or more Ω-3 fatty acids.

2. The preparation according to claim 1 , characterized in that α-linolenic acid is included as the 5-3 fatty acid.

3. The preparation according to claim 1 , characterized in that the triglyceride fraction contains linseed oil.

4. The preparation according to claim 1 , characterized in that (c) contains calcium carbonate as the inorganic filler.

5. The preparation according to claim 1 , characterized in that in addition to the vulcanizing agent at least one organic curing accelerator and/or at least one metal oxide is included.

6. The preparation according to claim 1 , characterized in that it contains at least one rheology additive as the inorganic filler.

7. The preparation according to claim 1 , characterized in that it further contains at least one antioxidant.

8. A method for joining metal parts and/or for sealing joins between metal parts, characterized in that
a preparation according to claim 1 is applied to at least one surface of at least one of the parts,
the parts to be joined are joined together,
and the joined parts are heated, optionally while being mechanically fixed in position, to cure the preparation.

9. A method for coating components by spraying a preparation according to claim 1 onto the surface of the part and heating the coated part to cure the preparation.

10. The method for coating components according to claim 9 , characterized in that the preparation is sprayed onto the substrate in airless, air-assisted or Airmix spraying methods, flat-stream methods or swirl methods.

11. The preparation according to claim 1 , wherein the fatty acid distribution of the triglyceride fraction, has a proportion of at least 60 wt. % of one or more Ω-3 fatty acids and/or one or more Ω-6 fatty acids.

12. The preparation according to claim 1 , further comprising at least one natural antioxidant.

13. The preparation according to claim 1 , wherein (c) comprises at least one rheology additive selected from silicon dioxide, carbon black and combinations thereof.

14. The preparation according to claim 1 , wherein the triglyceride fraction (a) is present in an amount from 5 to 50 wt. %, relative to the total preparation.
