Resin mixture based on vinyl ester urethane resin and use thereof
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.
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.

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.
