Abstract
Curable polymer mixtures comprising at least one oligomeric addition product with hydrolyzable silane groups and additional functional groups as the mediator additive, and a curable polymer system having epoxy group-carrying polymers and curing agents, fillers and optionally addditives; polymer concrete mixtures and molded bodies produced therefrom.
Claims20
A curable polymer mixture comprising
- I) a) at least one at least oligomeric addition product of at least one aminosilane and optionally thiosilane having at least one hydrolyzable silane group or
- a combination of at least one such aminosilane and/or thiosilane and at least one further monoamine and/or polyamine having at least 2 amino groups
- onto at least one compound having at least two terminal, ethylenically unsaturated double bonds
- and/or
- b) at least one at least oligomeric addition product
- of at least one isocyanatosilane and/or epoxysilane having at least one hydrolyzable silane group
- onto at least one compound having at least one terminal hydroxy group and at least one terminal, ethylenically unsaturated double bond in combination with at least one monoamine and/or polyamine having at least 2 amino groups
- and/or
- c) at least one at least oligomeric addition product
- of at least one silane having at least one hydrolyzable group and at least one (meth)acrylate group
- or at least one silane having at least one hydrolyzable silane group and at least one cyclic dicarboxylic anhydride group
- onto at least one compound having at least two terminal amino groups
- and/or
- d) at least one at least oligomeric addition product
- of at least one isocyanatosilane and/or epoxysilane having at least one hydrolyzable silane group
- onto at least one compound having at least two terminal amino groups optionally in combination with at least one further monoisocyanate and/or an epoxide compound,
- in an amount of less than 5% by weight, based on the total weight of the polymer mixture, as coupling additive,
- II) as binder
- a curable system which comprises at least one polymer having at least two epoxide end groups and can be at least partially cured by interaction of the epoxide groups of this polymer with the amino groups of at least one of the components I) a)-d) and at least one further hardener component and optionally an accelerator,
- III) at least 20% by weight, based on the total weight of the polymer mixture, of inorganic, optionally multiparticulate fillers as aggregates and
- IV) optionally customary auxiliaries.
