PRODUCTION OF COMPOSITE BUILDING MATERIAL

摘要

A textured building material, suited for use as an acoustical wall and ceiling covering, comprising a cellular urethane foam substrate and an elastomeric coating and a method for its production is disclosed. The building material is flexible and damage resistant, which makes it especially useful in mobile vehicles and homes. The process consists of applying a foamed elastomeric resin emulsion onto a urethane substrate to a desired thickness; drying the coated substrate thus formed; and thereafter crushing the dried elastomeric coated substrate to form a composite textured material.
