Acryloid cement formula provides the sealed binder with thermal stability hardening, and improves shock resistance and shear resistant, and be applied to connecting element, especially structural detail.

摘要

An adhesive acrylic formulation comprises a monomeric acrylic phase and, in intimate mixture with the latter, a system which produces free radicals, an additive which improves the impact strength of the hardened adhesive formulation, an epoxide resin and possibly other additives. Said additive consists of a cross-linked polyurethane network formed in situ in the monomeric phase from a polyurethane precursor system dissolved in said phase. The adhesive formulation also contains a latent hardener for the epoxide resin, the percentages by weight x of the monomeric phase, y of the polyurethane precursor system and z of the epoxide resin being such that 15 /= x /= 94,9, 0,1 /= y /= 60 and 5 /= z /= 90 and x+y+z=100 %. This adhesive formulation, which after hardening has improved thermal properties, impact strength and shear strength, can be used for example to bond structures.
