ADHESIVE COMPOSITION FOR FIBER

摘要

Disclosed are adhesive compositions for rubber and fiber which make synthetic fibers highly adhesive to rubber even when a reduced amount of the composition is applied to the fibers; rubber-reinforcing synthetic fibers coated with the adhesive composition to have improved adhesiveness to rubber while having the intrinsic characteristics of the synthetic fibers themselves; and fiber-reinforced rubber structures where the rubber has been reinforced by the rubberreinforcing synthetic fibers. The adhesive composition contains, in the adhesive matrix component, a silicate compound comprising silicon and magnesium as the essential constitutive elements at a ratio by weight of silicon/magnesium of from 1/0.1 to 1/1.0. Preferably, the 1 % aqueous dispersion of the silicate compound has a transmittance of 50 % or more and/or the 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.
