Abstract
Official abstract text for this publication.
Multi-component synthetic mortar fixing system, especially for fixing anchoring elements in building substrates, which comprises in one component reactive synthetic resins (i) based on urethane (meth)acrylate, (ii) based on epoxy resin or (iii) based on free-radical-hardening (or -hardenable) unsaturated reactive resins, in a further component hardener, and at least one filler selected from oxides of silicon and aluminium, or mixed oxides in the presence of further cations, the d50 average particle size of which is 50 μm or less, and also especially a silane having at least one hydrolysable group, and also its use, methods including its use in fixing anchoring elements in building substrates and related subject-matter.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of fixing an anchoring element in a hole or crevice in a building substrate, comprising introducing a multi-component synthetic mortar fixing system and an anchoring element into the hole or crevice, and allowing the multi-component synthetic mortar fixing system to cure, wherein the multi-component synthetic mortar fixing system comprises in one component reactive synthetic resins (i) based on urethane (meth)acrylate, (ii) based on epoxy resin or (iii) based on free-radical-hardenable unsaturated reactive resins, in a further component hardener; and at least one filler selected from oxides of silicon and aluminium, and from mixed oxides in the presence of further cations, wherein each filler comprises the d50 average particle size of which is 10 μm or less. 2. The method according to claim 1 , wherein in the multi-component synthetic mortar system the fillers are selected from those mentioned except for the mixed oxides. 3. The method according to claim 1 , wherein in the multi-component synthetic mortar system the at least one filler is quartz. 4. The method according to claim 1 , wherein in the multi-component synthetic mortar system, as further additive, at least one silane including at least one Si-bonded hydrolysable group, or the filler is present in a form modified using such a silane. 5. The method according to claim 4 , wherein in the multi-component synthetic mortar system, as silane, 3-(meth)acryloyl-oxypropyl-trimethoxysilane or -triethoxysilane, 3-(meth)acryloyl-oxymethyl-trimethoxysilane or -triethoxysilane, 3-(meth)acryloyl-oxypropylmethyldimethoxysilane, vinyltrimethoxysilane, vinyltriethoxysilane, or tetraalkoxysilane, or a mixture of two or more thereof, is present and/or the filler is surface-modified therewith. 6. The method according to claim 1 , wherein in the multi-component synthetic mortar system, as reactive synthetic resin, there is used one (ii) based on epoxy or (iii) based on free-radical hardening unsaturated reactive resins. 7. The method according to claim 1 , wherein in the multi-component synthetic mortar system, as reactive synthetic resin, there is present one based on urethane (meth)acrylate. 8. The method according to claim 7 , wherein in the multi-component synthetic mortar system the reactive synthetic resin based on urethane (meth)acrylate results from the reaction of a prelengthened monomeric di- or poly-isocyanate and/or from the reaction of a polymeric di- or poly-isocyanate with hydroxyethyl or hydroxypropyl (meth)acrylate. 9. The synthetic mortar fixing system according to claim 1 in the form of a two-component system.
