| titleOfInvention | Boiling-resistant solvent-free adhesive for flexible package and preparation method thereof |
| abstract | A boiling-resistant solvent-free adhesive for flexible packages comprises a component A and a component B, wherein the component A is an isocyanate-terminated polyurethane prepolymer obtained by reacting at least two of polyester diol, polyether diol and vegetable oil polyol with a diisocyanate compound, and the component B is a polyol mixture consisting of polyether diol and/or polyether triol and polyacrylate polyol; the viscosity of the component A is 1000-4000mPa.s, the weight content of isocyanate group is 13-18%, the viscosity of the component B is 500-2000mPa.s, and the hydroxyl value is 50-180 mgKOH/g; the component A and the component B are mixed according to the proportion to obtain the adhesive with the viscosity of 500-800mPa.s at the temperature of 35-45 ℃. The invention can provide excellent curing peel strength of the composite film, can still maintain good peel strength after being cooked at 135 ℃, and is suitable for the fields of medicine, food packaging, industrial packaging and the like. |
