Two component mortar composition and its use

摘要

Two-component mortar composition comprises: a resin component (A), which is curable by a redox initiator system and contains at least one radically-polymerizable resin, a reactive diluent mixture, a filler, and a thickening agent; and a curing agent component (B), which is disposed separately to inhibit reaction and contains a peroxide as a component of a redox initiator system, polymer particles from polymer or mixture of polymers produced by aqueous emulsion polymerization, accelerator as second component of redox initiator system, water, fillers, and thickening agents. Two-component mortar composition comprises: a resin component (A), which is curable by a redox initiator system and contains 5-30 wt.% of at least one radically-polymerizable resin, 3-45 wt.% of a reactive diluent mixture, 30-75 wt.% of a filler, and 1-8 wt.% of a thickening agent; and a curing agent component (B), which is disposed separately to inhibit reaction and contains 1-20 wt.% of a peroxide as a component of a redox initiator system, 1-25 wt.% of polymer particles from 70-99.9 wt.% of a polymer or mixture of polymers produced by aqueous emulsion polymerization, 0.1-30 wt.% of an accelerator as a second component of the redox initiators system and which is covalently bound in the polymer particles or is encapsulated in the polymer particles, 10-35 wt.% of water, 40-80 wt.% of fillers, and 0.5-5 wt.% of thickening agents, where the reactive diluent mixture contains at least a hydroxyalkyl (meth)acrylate, at least an alkyl (meth)acrylate and at least an acetoacetato compound of formula (CH 3-C(=O)-CH 2-C(=O)-R1) (I). R1 : H, 1-6C alkyl or -OR2; R2 : 1-6C alkyl, (CH 3-(CH 2) n-O-C(=O)-C(=CH 2)-CH 3) or (CH 3-CH 2-C-(C 2H 5)(CH 2-O-CH 2-C(=O)-CH 2-C(=O)-CH 3)-CH 2-O-C(=O)-CH 2-C(=O)-CH 3); and n : 1-6.
