Abstract

Multi-component synthetic resin adhesive composition for the fixing sector, especially for adhesively bonding an anchoring element in a hole (for example, a drilled hole) or crevice, comprising fillers, which comprises a biogenic liquid diluting agent (for example a vegetable oil, such as especially castor oil, or a polyol); use of the synthetic resin adhesive composition for embedding anchoring means in mortar in holes or crevices; process or method for embedding anchoring elements in mortar and holes or crevices, in which the synthetic resin adhesive composition is used; and use of biogenic fillers in producing such a synthetic resin adhesive composition.

First claim

The invention claimed is:

1. A method of embedding an anchoring means in holes or crevices, the method comprising:
introducing a multi-component synthetic resin adhesive composition and an anchoring means into a hole or crevice, the multi-component synthetic resin adhesive composition comprising at least one non-reactive diluent comprising at least one biogenic, non-reactive diluent that is liquid at application temperature; and
causing the synthetic resin adhesive composition to cure;
wherein the term biogenic means that the reactive diluent comprises bio-based carbon obtained from plants or vegetable materials or from animal sources, which is detected by means of the 14 C method in accordance with ASTM 6866 2008, Method A, and
wherein the at least one biogenic, non-reactive diluent comprises at least one of castor oil, linseed oil, soybean oil, epoxidized soybean oil, hydroxylated soybean oil, hydroxy alkylated soybean oil or rapeseed oil, or fatty acid alkyl esters.

2. A method according to claim 1 , wherein the at least one biogenic, non-reactive diluent comprises castor oil.

3. The method according to claim 1 , wherein the biogenic non-reactive diluent is, in total, provided in a proportion of from 5% to 20% by weight or from 21% to 30% by weight.

4. The method of claim 1 , wherein the synthetic resin adhesive composition comprises a reactive resin component (A) comprising a reactive synthetic resin based on epoxy or a free-radical-hardenable reactive synthetic resin, and a hardener component (B).

5. The method according to claim 4 , wherein the biogenic, non-reactive diluent is in the hardener component (B).

6. The method of claim 4 , wherein the reactive synthetic resin component (A) comprises a free-radical-hardenable reactive synthetic resin and hardener component (B) comprises a peroxide as initiator.

7. The method of claim 4 , wherein the reactive synthetic resin component (A) comprises at least one epoxy(meth)acrylate having the formula

wherein n denotes a number greater than or equal to 1, and/or at least one ethoxylated aromatic diol-(meth)acrylate having the formula

wherein a and b each, independently of the other, denote a number greater than or equal to 0, with the proviso that at least one of the values is greater than 0, or both values are 1 or more, or a propoxylated analogue thereof, and/or one of more urethane (meth)acrylates.

8. The method of claim 1 , wherein the multi-component synthetic adhesive composition further comprises at least one additive selected from aminic accelerators, inhibitors, reactive diluents, thixotropic agents, plasticisers, flexibilizers, stabilisers, rheology aids, wetting and dispersing agents, and colouring additives.

9. The method of claim 1 , wherein the synthetic adhesive composition comprises:
a) a hardenable reactive resin;
b) a hardenable reactive diluent having a viscosity <800 mPa*s, measurable using a Brookfield viscosimeter at 23° C. with a no. 3 spindle at 20 rpm,
c) a hardener, by means of which a.) and b.) are hardened and/or by means of which the hardening thereof is initiated; and
d) the biogenic non-reactive diluent.

10. The method of claim 1 , wherein the synthetic adhesive composition comprises
a) a reactive resin having 2 or more unsaturated groups;
b) a reactive diluent having unsaturated groups and having a viscosity of <800 mPa*s; measurable using a Brookfield viscosimeter at 23° C. with a no. 3 spindle at 20 rpm:
c) an aminic accelerator;
d) an inhibitor;
e) a free radical initiator; and
f) at least 3% of the biogenic non-reactive diluent.

11. The method of claim 1 , wherein the synthetic adhesive composition comprises
the biogenic non-reactive diluent and a reactive synthetic resin component (A) comprising at least one biogenic filler, an epoxy(meth)acrylate and/or a propoxylated or ethoxylated aromatic diol-di(meth)acrylate, and/or urethane (meth)acrylate, at least one reactive diluent in the form of an olefinic compound selected from mono-, di-, tri- or poly-(meth)acrylates, hydroxyalkyl (meth)acrylates, or two or more thereof, a phenolic and/or non-phenolic inhibitor, an aminic accelerator, a thixotropic agent and a further filler, and
a hardener component (B) comprising a free-radical-forming peroxide, a filler, a thixotropic agent and optionally a pigment.

12. A method of embedding an anchoring means in holes or crevices, the method comprising
introducing a multi-component synthetic resin adhesive composition and an anchoring means into a hole or crevice, the multi-component synthetic resin adhesive composition comprising at least one non-reactive diluent comprising at least one biogenic, non-reactive diluent that is liquid at application temperature; and
causing the synthetic resin adhesive composition to cure;
wherein the term biogenic means that the reactive diluent comprises bio-based carbon obtained from plants or vegetable materials or from animal sources, which is detected by means of the 14 C method in accordance with ASTM 6866 2008, Method A, and
wherein the synthetic resin adhesive composition is provided as a two-component kit, having a reactive synthetic resin component (A) and a hardener component (B), wherein the biogenic, non-reactive diluent is in the synthetic resin component (A).

13. The method according to claim 12 , wherein the at least one biogenic, non-reactive diluent comprises at least one of castor oil, linseed oil, soybean oil, epoxidized soybean oil, hydroxylated soybean oil, hydroxy alkylated soybean oil or rapeseed oil, or fatty acid alkyl esters.

14. A method according to claim 12 , wherein the at least one biogenic, non-reactive diluent comprises castor oil.

15. The method according to claim 12 , wherein the biogenic non-reactive diluent is, in total, provided in a proportion of from 5% to 20% by weight or from 21% to 30% by weight.

16. The method of claim 12 , wherein the synthetic resin adhesive composition comprises a reactive resin component (A) comprising a reactive synthetic resin based on epoxy or a free-radical-hardenable reactive synthetic resin, and a hardener component (B).
