[0086] Hereinafter, although an Example and a comparative example are given and this invention is demonstrated in more detail, this invention is not limited to these Examples and a comparative example.
[0087] (Example and Comparative Example)
[0088] Each component was compounded with the compounding recipe shown in Table 1 and Table 2, and these were mixed with the mixing roll, and the resin composition was made into a kneaded product. In addition, the compounding quantity of each component in a table shows "weight part."
[0089] In the above kneading, first, epoxy resin, acrylonitrile butadiene rubber, filler, low-grade rubber, and tackifier are kneaded with a roller kneader heated to 120°C. , and then cool the kneaded product to 50-80°C, further add epoxy curing agent, epoxy curing accelerator, vulcanizing agent, vulcanization accelerator, foaming agent, and prepare a resin that is kneaded by a roller mixer combination.
[0090] Then, the above-mentioned resin compos...

Abstract
The present invention relates to a reinforcing material for outer panel, which is adhered to an outer panel for reinforcing the outer panel, in which the reinforcing material has: a 1 mm displacement strength of 20 N or more when adhered to an entire surface of a cold-rolled steel plate having a size of 25 mm width150 mm length0.8 mm thickness and then heated at 180 DEG C. for 20 minutes; and a strain amount of 170 [mu]m or less when adhered to a center part of an aluminum panel having a size of 200 mm width300 mm length1 mm thickness, in the form of a rectangular having a size of 50 mm width100 mm length, and then heated at 180 DEG C. for 20 minutes.
Description
technical field [0001] The present invention relates to a reinforcing material for an outer panel and a method for reinforcing the outer panel, and specifically relates to a reinforcing material for an outer panel for reinforcing the outer panel of various industrial machines such as a transportation machine, and a reinforcing method for the outer panel method. Background technique [0002] Conventionally, in order to reduce the weight of the vehicle body, the outer panel of the vehicle body is usually processed into a thin-walled steel plate of 0.6 to 0.8 mm. Therefore, it is practiced to stick a steel plate reinforcing sheet on the inner side of the thin steel plate for reinforcement. [0003] In addition, as such a steel sheet reinforced sheet, a sheet in which a sheet-like resin layer composed of a thermosetting resin composition is laminated on a constraining layer such as glass cloth or a thin metal plate is known, and as a thermosetting resin composition, an epoxy re...
