Embodiment 1
[0042] Anti-Slip Seal Compound (Black Rigid):
[0043] First, prepare the phenol-terminated latex of polyurethane prepolymer according to the following steps
[0044] The first step, the preparation of polyurethane prepolymer
[0045] Accurately weigh 100 parts of polyether N210, and dehydrate in vacuum for 2 hours at a temperature of 120°C and a pressure of -0.09MPa. When the temperature drops to 50°C, add 31 parts of TDI-80, After reacting for 1 hour, the temperature was raised to 80° C. and then reacted for 3 hours. After the reaction was completed, vacuum defoaming was performed for 30 minutes to obtain a polyurethane prepolymer with a mass content of -NCO groups of 5%.
[0046] The second step, phenol capping reaction
[0047] (1) at first in 13 parts of phenol, add the dibutyltin dilaurate catalyst of 0.15 part, stir after standby;
[0048] (2) Add the polyurethane prepolymer prepared in the first step into the reactor, and after heating to 80°C, in the state of stirr...
Embodiment 2
[0057] Anti-Slip Seal Compound (Red Rigid):
[0058] First, prepare the phenol-terminated latex of polyurethane prepolymer according to the following steps
[0059] The first step, the preparation of polyurethane prepolymer
[0060] Accurately weigh 100 parts of polyether N210, and dehydrate in vacuum for 2 hours at a temperature of 120°C and a pressure of -0.09MPa. When the temperature drops to 50°C, add 44 parts of TDI-80, After reacting for 1 hour, the temperature was raised to 80° C. and then reacted for 3 hours. After the reaction was completed, vacuum defoaming was performed for 30 minutes to obtain a polyurethane prepolymer with a mass content of -NCO group of 9%.
[0061] The second step, phenol capping reaction
[0062] (1) First, add 0.2 parts of dibutyltin dilaurate catalyst to 24 parts of phenol, shake well and set aside;

Embodiment 3
[0072] Anti-Slip Seal Compound (Green Elastic):
[0073] First, prepare the phenol-terminated latex of polyurethane prepolymer according to the following steps
[0074] Preparation of Polyurethane Prepolymer
[0075] Step 1: Accurately weigh 100 parts of polyether N210, and dehydrate in vacuum for 2 hours at a temperature of 120°C and a pressure of -0.09MPa. When the temperature drops to 50°C, add 37.3 parts of TDI-80. After reacting at 50°C for 1 hour, the temperature was raised to 80°C and then reacted for 3 hours. After the reaction was completed, vacuum defoaming was performed for 30 minutes to obtain a polyurethane prepolymer with a mass content of -NCO groups of 7%;
[0076] The second step, phenol capping reaction
[0077] (1) first add the dibutyltin dilaurate catalyst of 0.17 part in the phenol of 18.8 parts, stir after standby;
[0078] (2) Add the polyurethane prepolymer prepared in the first step into the reactor, and after heating to 80°C, in the state of stirr...
