Abstract
The invention relates to a halogen-free flame retardant adhesive, which comprises, by weight, 15-45 parts of halogen-free epoxy resin; 15-60 parts of thermoplastic resin and/or synthetic rubber; 0.1-8 parts of a curing agent; 5-60 parts of phosphorus-containing composite flame retardant. The halogen-free flame-retardant adhesive has good flame retardance, peeling strength, electrical property and welding heat resistance, does not contain harmful substance elements such as halogen, antimonide and the like, and does not pollute the environment. The flame retardant grade of the flexible copper clad laminate prepared by the composition reaches UL-94V0 grade, and the flexible copper clad laminate also has good heat resistance, high peel strength and soldering resistance, and does not delaminate and foam after being dipped in tin for 1min at 310 ℃. The halogen-free flame-retardant adhesive has good covering performance, so that the production line speed can be increased and the production efficiency can be improved.
