Abstract

A resin mixture comprises a vinyl ester urethane resin as the base resin, wherein the vinyl ester urethane resin can be obtained by reacting a dianhydrohexitol compound with a diisocyanate to obtain a product and reacting the obtained product with a hydroxy substituted (meth)acrylate. The resin mixture can be used to produce a reactive resin mortar containing that resin mixture and inorganic aggregates, organic aggregates or a mixture thereof. The reactive resin mortar can be used for chemical fastening.

First claim

The invention claimed is:

1. A resin mixture, comprising:
a base resin comprising a vinyl ester urethane resin, wherein the vinyl ester urethane resin
is obtained by
(i) reacting at least two moles of a diisocyanate per mole of a dianhydrohexitol compound to obtain a product, and
(ii) reacting the obtained product with a hydroxy-substituted (meth)acrylate to obtain the vinyl ester urethane resin.

2. The resin mixture of claim 1 , wherein at least two moles of hydroxy-substituted (meth)acrylate per mole of the product from the reaction of (i) are used.

3. The resin mixture of claim 1 , wherein the dianhydrohexitol compound is isosorbide.

4. The resin mixture of claim 1 , wherein the diisocyanate is an aliphatic diisocyanate.

5. The resin mixture of claim 4 , wherein the aliphatic diisocyanate is tetramethylene diisocyanate, hexamethylene diisocyanate or decamethylene diisocyanate.

6. The resin mixture of claim 1 , wherein the hydroxy-substituted (meth)acrylate is a hydroxyalkyl(meth)acrylate.

7. The resin mixture of claim 6 , wherein the hydroxyalkyl(meth)acrylate is hydroxypropyl(meth)acrylate or hydroxyethyl(meth)acrylate.

8. The resin mixture of claim 1 , wherein the starting compounds for preparing the base resin is obtained from renewable resources.

9. The resin mixture of claim 1 , wherein up to 80% of the carbon is derived from renewable resources.

10. A reactive resin mortar, comprising:
the resin mixture of claim 1 , and
an inorganic aggregate, an organic aggregate or a mixture thereof.

11. The reactive resin mortar of claim 10 , wherein the aggregates are selected from fillers and additives.

12. The reactive resin mortar of claim 10 , wherein the content of the resin mixture is 10 to 60% by wt. of the reactive resin mortar.

13. A two component reactive resin mortar system, comprising:
a reactive resin mortar of claim 10 , and a hardener.

14. The two component reactive resin mortar system of claim 13 , wherein the hardener contains a radical initiator as the curing agent and optionally an inorganic aggregate, an organic aggregate or a mixture thereof.

15. A reactive resin mortar, comprising:
a resin mixture comprising:
a base resin comprising a vinyl ester urethane resin, wherein the vinyl ester urethane resin
is obtained by
(i) reacting at least two moles of a diisocyanate per mole of a dianhydrohexitol compound to obtain a product, and
(ii) reacting the obtained product with a hydroxy-substituted (meth)acrylate to obtain the vinyl ester urethane resin, and

at least one inorganic aggregate selected from the group consisting of silica sand, cement and pyrogenic silicic acid,
wherein a content of the resin mixture in the reactive resin mortar is 10 to 60% by wt. of the reactive resin mortar.
