<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a laminate having good workability and stable quality of product, capable of reducing manufacturing cost and improving impact resistance. <P>SOLUTION: A manufacturing method of a bathtub comprises; putting a thermoplastic resin molding shaped to a predetermined shape beforehand on a male mold having mostly same profile with this thermoplastic resin molding; forming a cell by positioning a female mold in the counter side of this male mold having a predetermined spacing with this thermoplastic resin molding; casting a mixed liquid of a polymerization-hardenable resin raw material and a filler in this cell from the inlet of this female mold in the condition sealing the peripheral part of this thermoplastic resin molding and the peripheral part of this female mold and performing mold clamping; and hardening this. In addition, the temperature of the mixed liquid to be cast is within the range of 30-60°C and the viscosity is within the range of 100-8,000 mPa×s in the manufacturing method of the laminate. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
