Examples
Embodiment 1
[0017] Weigh 15 kilograms of pentaerythritol, Add 8 kg and 45 kg of water into a three-neck flask equipped with a stirrer, stir thoroughly for 30 minutes, add 25 kg of water-based polyurethane emulsion PUD-336 within 10 minutes, stir at 500 rpm for 50 minutes, and finally use SRH high-shear homogenization The emulsification pump shears for 60 minutes to prepare a waterborne polyurethane flame retardant coating.
Embodiment 2
[0019] Prepare water-based polyurethane flame-retardant coating in the same manner as Example 1, except that no
[0020]
experiment example
[0022] Refer to GB15442.2-1995 "Large Plate Combustion Method" to measure the flame retardancy of the coatings in Examples 1 and 2. The flame retardant time of the coating in Example 1 is 561.5±3.0 seconds, and the flame retardant time of the coating in Example 2 is 368.5±3.5 seconds. It can be seen that after adding the flame retardant additive, the flame retardancy of the coating is significantly enhanced, and the results of Example 1 are compared with those of Example 2, and the difference is statistically significant (P<0.05).
