Beschreibung
Zusammenfassung:	An efficient flame-retardant insulating EVA hot melt adhesive comprises: 20-35 wt% of an ethylene-vinyl acetate copolymer (EVA); 15-30 wt% of a tackifier; 3-10 wt% of paraffin; 1-5 wt% of a plasticizer; 0.5-2 wt% of an antioxidant; 0.5-2 wt% of a toughening agent; 0.5-2 wt% of an anti-dripping agent; and 25-40 wt% of a flame retardant. An efficient flame-retardant system which has hydrolysis-resistant and multi-flame-retardant elements and a multi-phase synergistic flame-retardant effect on the hot melt adhesive is selected, so that the flame-retardant efficiency of the hot melt adhesive is improved, and the prepared flame-retardant EVA hot melt adhesive has good flowability, insulativity and flame retardant precipitation resistance. The EVA hot melt adhesive provided by the invention has good bonding strength and excellent electrical insulation property for polymer materials, can be used for repairing aged cables in the fields of locomotives, electronic devices and the like, prolongs the service life of the
