The feasibility of EVA hot melt adhesive preparation by rosin continuous method was discussed in this paper. The advantages and disadvantages of continuous method and multistep method were compared by contrast experiments, reasonable time of rosin esterification and proper mass ratio of rosin with EVA were investigated in adhesive preparation by continuous method. The results show that it is feasible for EVA hot melt adhesive preparation by rosin continuous method in the experimental stage;compared with multistep method, the hot melt adhesive prepared by continuous method has the traits with light color and strong adhesion; 30/50~40/5 when ZnO (0.3%of rosin) is the catalyst, pentaerythritol amount is 15%of rosin, the dosage of compound antioxidant is 0.2% of rosin, paraffin quality is 10% of the EVA, the reaction temperature is 270 ℃ , the system rubber temperature is 200 ℃, the reasonable time of rosin esterification is 6 to 7 hours in adhesive preparation by continuous method, the suitable mass ratio of rosin with EVA is 30/50~40/50;EVA hot melt adhesive prepared in this process appeared the color of light yellow, bond strength of 675 g, fluidity of 2.5mm/10g.
