EPOXY RESIN COMPOSITION FOR REINFORCING CAR BODY, CAR BODY REINFORCEMENT STRUCTURE, AND METHOD FOR REINFORCING CAR BODY

摘要

PROBLEM TO BE SOLVED: To provide an epoxy resin compsn. for reinforcing car bodies which can be foamed easily and uniformly in a box-shaped member to fill it and can surely increase the stiffness of a car body, and to provide a car body reinforcement structure, and a method for reinforcing car bodies using the same. ;SOLUTION: This compsn. comprises 100 pts.wt. epoxy resin derived from bisphenol A and/or bisphenol F, 1-40 pts.wt. arom. polyether, 3-30 pts.wt. thermally activated curative for epoxy resins, 0.5-20 pts.wt. thermally decomposable org. blowing agent, and 3-200 pts.wt. inorg. filler. This method for reinforcing a car body comprises arranging a sheet comprising the compsn. in the inside of a box-shaped member and foaming the sheet at the step of baking in the electrodeposition coating of a car body. This car body reinforcement structure is a box-shaped member filled with a foam of the compsn.;COPYRIGHT: (C)1998,JPO
