Zusammenfassung:The invention discloses a hemming structural adhesive with lightweight and good grease surface fixity as well as a determination method, and relates to the technical field of chemical materials. The hemming structural adhesive comprises the following components in percentages by weight: 25-35% of bisphenol F type epoxy resin; 25-35% of epoxy modified organic silicone resin; 3-5% of a curing agent; 0.8-1.2% of a promoter; 1.4-4% of gas phase white carbon black; 1-1.5% of hollow glass beads; 29-35% of a filling material; and 0.3-0.5% of a pigment. The adhesive has environmental protection and low density, lightweighting of the product is better realized, and problems of easy deformation and flowing of high strength structural adhesive squeezing-coating crude adhesive tapes which are applied to the position with larger gaps between automobile body grease surface steel plates, and disjointing of adhesive tape bonding after lines are coated. 本发明公开了种具有轻量化、油面固定性好的折边结构胶及测定方法,涉及化工材料技术领域,按照重量百分比计,其包括以下组分:双酚F型环氧树脂25~35%
