| titleOfInvention | Castor oil-based polyurethane-acrylonitrile composite emulsion adhesive for leather and preparation method thereof |
| abstract | The invention relates to a preparation method of castor oil-based polyurethane-acrylonitrile composite emulsion adhesive for leather. Its preparation method is: mix 10wt%～20wt% castor oil, 30wt%～40wt% polytetrahydrofuran ether glycol, 10wt%～30wt% diisocyanate and 0wt%～5wt% catalyst, under N2 gas and 50 ℃～100℃ for 1～6h, then add 4wt%～8wt% dimethylol fatty acid, react for 1h～6h under 50℃～100℃, then add 3wt%～6wt% triethylamine And, then add a sufficient amount of deionized water and stir at 3000r/min to obtain a polyurethane emulsion with a solid content of 40%, and then add 10wt% to 20wt% of acrylonitrile and 1wt% to 6wt% to the prepared polyurethane emulsion The initiator is reacted at 50°C-100°C for 1h-6h to prepare castor oil-based polyurethane-acrylonitrile composite emulsion adhesive. The invention is an effective method for preparing environment-friendly emulsion adhesive by utilizing renewable resources. |
