The invention discloses a high-speed compounding and online peeling
polyurethane transfer
adhesive which comprises a component A and a component B. The component A comprises, in weight percent, 30-70%of polymers A1, 1-10% of polymers A2, 20-60% of polyisocyanate, 0.5-2% of
coupling agents and 0.1-1% of leveling agents, the polymers A1 is one of polyether
polyol and
polyester polyol or mixture ofthe polyether
polyol and the
polyester polyol, the functionality of the polyether polyol is 2, the polymers A2 is one of
polyester polyol and polyether polyol or mixture of the polyester polyol and the polyether polyol, and the functionality of the polyester polyol is larger than or equal to 3. The component B comprises, in weight percent, 5-25% of amine chain extenders, 0.1-1% of amine catalystsand the
balance water. The invention further provides a preparation method of the high-speed compounding and online peeling
polyurethane transfer
adhesive. The high-speed compounding and online peeling
polyurethane transfer
adhesive is used for production of transfer aluminized paper, high-speed compounding and online peeling can be achieved, improvement of production speed is facilitated, energyconsumption and production cost are reduced, and the adhesive has high bending resistance and good
heat resistance and anti-sticking property and is safe and
environmentally friendly.
