Problems solved by technology

[0011] The disadvantage of the reaction product with cyclic carbonate groups according to the mentioned document is that the product occurs as a solid, or at least has an extremely high viscosity with a partial tendency to crystallize
Another disadvantage is that heat curing is necessary
These disadvantages make products with cyclic carbonate groups unsuitable as solvent-free cold-curing multi-component systems for fixing anchors in boreholes or cracks, e.g. cartridge shells (Kartusche) - injection molding systems

Embodiment 1

[0115] Example 1: General Operating Regulations I: Cyclic Carbonate Using 4,4'-Diphenylmethane Dicarbamate Diglycerol Carbonate and Trimethylolpropane Triglycidyl Ether as Reactive Diluents Synthesis of resin:

[0116] In a 250 mL glass flask with reflux condenser and with drying tube, stirrer, dropping funnel and thermometer - in the amounts mentioned in Table 1 (Example 3) - pre-place trimethylolpropane triglycidol ether and glycerol carbonate and heated to 60°C in an oil bath. "PMDI" was slowly added dropwise to the reaction mixture so that the temperature did not exceed 80°C. After complete addition of "PMDI", stirring was continued at 80°C to complete the reaction. The completed reaction was checked by means of FT-IR (no isocyanate groups detectable by IR-spectroscopy).

Embodiment 2

[0117] Example 2: General Procedure II: 4,4'-Diphenylmethane dicarbamate diglycerol carbonate with trimethylolpropane triglycidyl ether and neopentyl glycol diglycidyl ether as reactive Alternative Synthesis of Cyclic Carbonate Resins Example of Diluent-Mixture:

[0118] Trimethylolpropane triglycidyl ether, neopentyl glycol diglycidyl ether and glycerol carbonate were pre-placed in the amounts mentioned in Table 3 (Example 4) in a 120 mL plastic cup with a screw cap. After mixing well, add "PMDI" at room temperature and re-mix to a streak-free appearance. The plastic cup containing the reaction mixture was then stored at 40°C to complete the reaction. The completed reaction was checked by means of FT-IR (no isocyanate groups detectable by IR-spectroscopy).

Embodiment 3

[0119] Embodiment 3: the prescription of carbonate resin I:

[0120] The formula of the resin prepared according to embodiment 1 is:

[0121] name Weigh m [g] weight% trim 57.81 60.00 glycerol carbonate 18.54 19.24 "PMDI" 20.00 20.76

[0122] "PMDI" refers to mixtures of MDI (isocyanate functionality 2) and PMDI (isocyanate functionality 3.2) and / or monofunctional isocyanates (isocyanate functionality 1.0) according to Table 2.

[0123] MDI: diphenylmethane diisocyanate - isomer mixture, molecular weight 250 g / mol, isocyanate - functionality 2 (manufacturer's instructions)

[0124] PMDI: diphenylmethane diisocyanate with isomers and homologues of higher degree of functionality, molecular weight 430 g / mol, isocyanate-functionality 3.2 (manufacturer's instructions)

[0125] p-TSI: p-toluenesulfonyl isocyanate, molecular weight 197.21 g / mol, isocyanate-functionality 1

Abstract

Synthetic resin fixing system based on cyclic carbonate resins, characterised in that as cyclic carbonate resin it comprises at least one having an average functionality of 1.5 or more than 1.5 cyclic carbonate groups per molecule, the production thereof and use thereof for fixing, especially, anchoring means in drilled holes.

Description

technical field [0001] The present invention relates to novel synthetic resin-fixation systems based on cyclic carbonate resins, their use in the field of fixation, in particular for fixing anchoring elements in boreholes or cracks, their preparation and the following obvious aspects associated therewith Other inventive subjects. Background technique [0002] Synthetic resin materials based on unsaturated polyester resins or vinyl ester resins or based on epoxides are known as adhesives for anchoring in chemical fixing techniques, for example for fixing anchors in boreholes. Here, two-component systems are generally used, one component comprising the reactive resin and the other component comprising the hardener. By mixing the two components, the reaction leading to curing is triggered. [0003] In principle, polyurethane-based fastening systems that cure by polyaddition are also known for fastening, for example, anchoring elements in boreholes as so-called "docks", see fo...
