Adhesive compositions for rubber and fiber, rubber-reinforcing synthetic fibers, and fiber-reinforced rubber structures

摘要

An adhesive composition suitable for adhering rubber and fiber to one another comprises an adhesive matrix containing a silicate compound. The silicate compound comprises as essential elements silicon and magnesium at a ratio by weight of silicon/magnesium of from 10/1 to 1/1.0. Additionally or alternatively, a 1 % aqueous dispersion of the silicate compound has a transmittance of 50 % or more and/or a 2 % aqueous dispersion of the silicate compound has a thixotropy index of from 2.0 to 10.0. The silicate compound is preferably a smectite.
