MULTILAYER STRUCTURAL BUILDING MATERIAL

摘要

The invention relates to a multilayer structural building material suitable for use as a backing material in walls, ceilings, floors, etc. The material comprises a polyolefin or polybutadiene foam sheet as a base layer, a dry coated layer of a polychloroprene-type adhesive as an interlayer, and a dry coated layer of a mixture of a water-base adhesive and an inorganic filler as a surface layer. The material can be bonded by using a water-base adhesive instead of the organic solvent-base adhesives at the site of construction, and which even after the bonding operation, permits easy adjustment of the position of a surface material and easy removal of creases from the surface material.
