Abstract

PURPOSE: A sheet for a roof ground material, containing a high polymeric material consisting of a synthetic rubber and a synthetic resin having a specific strength and a desulfurized regenerated powdered rubber, and having improved tackiness, tensile strength and pinhole sealing effect.
CONSTITUTION: A composition prepared by incorporating (A) a high polymeric material consisting of a synthetic rubber and a synthetic resin having a green strength ≥ 50kg/cm2, e.g. butadiene simple copolymer, with (B) a desulfurized regenerated powdered rubber, e.g. styrene-butadiene copolymer pulverized to a particle diameter of 20W40 mesh, having a Mooney viscosity ML1+4 (100°C) of 20W60 and (C) an additive, e.g. a reinforcing filler, and kneaded and rolled to form a sheet for a roof ground material having a penetration ≥20 and a shrinkage ≤0.5%. A thin material, e.g. asphalt, having a shrinkage ≤0.5% is applied to one or both sides of the resultant sheet to give a reinforced composite sheet for the roof ground material.
