Preparation method of polyurethane hot melt adhesive capable of being bonded with low surface energy material |
| abstract |
The invention relates to a preparation method of a polyurethane hot melt adhesive capable of being bonded with a low surface energy material, the polyurethane hot melt adhesive prepared by the method has good flexibility and body tensile strength, can overcome the influence of the difference of expansion coefficients of different materials, and has uniform stress distribution, thereby being suitable for different types of base materials; the drop resistance is good: the roller falls more than 300 times; the bonding strength is high: the adhesive strength of the PEI and the nickel-plated steel sheet is higher than 6.0 MPa; the salt spray resistance and aging resistance are good: the salt spray test was not destructive for 500 hours, and the double 85 test was not significantly intensity decayed for 1000 hours. |
