METHOD FOR PRODUCING GLASS CHOPPED STRAND MAT, GLASS CHOPPED STRAND MAT, AND ROOF LINER

摘要

PROBLEM TO BE SOLVED: To provide a glass chopped strand mat that is flexible, has excellent strength, prevents partial breaking and damages and suppresses occurrence of defect of appearance; and a method for producing the same.;SOLUTION: The method for producing a glass chopped strand mat 19 includes: spraying a binder P on a sheet-like deposit 11b of a glass chopped strand 11a, heating the deposit, cooling and solidifying the softened binder and mutually binding the glass chopped strands. The binder P has a particle size distribution having an effective particle diameter D₅₀ (average particle diameter) of not less than 275 μm and not more than 325 μm, D₁₀ of not less than 240 μm and D₉₀ of not more than 390 μm in the grain size accumulation curve. The glass chopped strand mat 19 has a weight of 50 g/m²-200 g/m². The roof liner is obtained by bonding the glass chopped strand mat to a foamed resin sheet.;COPYRIGHT: (C)2011,JPO&INPIT
