Precoated surface material for vehicular interior material and manufacturing method of vehicular interior material

摘要: PROBLEM TO BE SOLVED: To provide a hot-melt adhesive having excellent heat resistance and used for precoated surface material vehicular interior material, giving with no viscosity to dispense the use of releasing paper formable bondable without heating molded article make it possible substantially simplify adhering process article, method manufacturing therein. SOLUTION: The is formed by applying back in advance. including, as essential components thereof, amorphous-poly (α-olefin) (A) which melt range 500 100,000m(Pa s)/190°C, tackifier resinr (B) softening point according ring ball 110°C or higher, polypropylene system wax (C) melting 120°C more. weight ratio 100/50 100/100. Since that allows remarkable simplification bonding step manufacturing, has good adhesiveness an olefin well being non-solvent, industrially useful. COPYRIGHT: (C)2005,JPO&NCIPI
