| Abstract: | The effect of the parts of glycol by mass in prepolymer synthesis and the mole ratio of NCO/OH and the parts of catalyst(organotin compound) by mass in adhesive preparation on the adhesion property of castor oilPU adhesive was investigated.The results showed that the optimal adhesion property of castor oilPU adhesive was obtained when 0.70 parts of glycol by mass in prepolymer synthesis and 0.0060.008 parts of catalyst by mass with the mole ratio of NCO/OH equal to 1.3 and 0.0040.006 parts of catalyst by mass with the mole ratio of NCO/OH equal to 1.4 in adhesive preparation were used;the adhesion property improved as the mole ratio of NCO/OH in adhesive preparation increased;and the castor oilPU adhesive featured better waterproofing. |
