Abstract
A new approach for preparation and use of adhesive for metal and fabric bonding is proposed in this invention. Generally, 80-120 g of epoxy resin, 10-30 g of reactive diluent, 0.5-5 g siliane coupling agent, 0.5-5 g metallic oxide nanopowder and 35-60 g curing agent are applied in the formula. With the treatment of silane coupling agent and the mixture of phosphoric acid and nitric acid respectively, the active groups are introduced onto the surface of the metal and the fabric, which enhanced the adhesive strength of metal/fabric interface. Simultaneously, the brittleness, poor cracking and impact resistance of the traditional epoxy adhesive are also optimized by using the method of this invention, which is easy to operate and widely used.
