| 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 oil-PU adhesive was investigated.The results showed that the optimal adhesion
property of castor oil-PU adhesive was obtained when 0.70 parts of glycol by mass in prepolymer synthesis and 0.006～0.008 parts of catalyst by mass with the mole ratio of —NCO/—OH equal to 1.3 and 0.004～0.006 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 oil-PU adhesive featured better waterproofing. |
