Embodiment 1
[0036] Example 1 Normal temperature vulcanization adhesive
[0037] (1) 140g of MDI is added to the reactor with a stirring system, condenser, dropping device, heating and cooling temperature control device, the system is heated to 60°C, and the mixture of 32g polypropylene glycol 400 and 320g polypropylene glycol 2000 is added dropwise to the reaction in about 30 minutes Stir in the bottle, after the dropwise addition, add 1g of dibutyltin dilaurate catalyst dropwise, and keep the temperature of the reaction system at 60°C to 65°C, after reacting for about 3.5 hours, take a sample to test that the free isocyanate group is less than 150ppm, and then Add 70g of β-hydroxyethyl (meth)acrylate dissolved in 0.5g of phenothiazine dropwise within 30 minutes, and control the temperature of the system in the reaction bottle not to exceed 80°C. After the dropwise addition, maintain the system at 65°C to 70°C After about 2.5 hours, add 300g of styrene, and then lower the temperature to 4...

[0042] Example [2] - medium and high temperature vulcanization adhesive
[0043] (1) 120g of MDI is added to the reactor with stirring system, condenser, dropping device, heating and cooling temperature control device, the temperature of the system is raised to 60°C, and the mixture of 30g polypropylene glycol 400 and 300g polypropylene glycol 2000 is added dropwise to the reaction in about 30min Stir in the bottle, after the dropwise addition, add 1g of dibutyltin dilaurate catalyst dropwise, and keep the temperature of the reaction system at 60°C to 65°C, after reacting for about 3.5 hours, take a sample to test that the free isocyanate group is less than 150ppm, and then Add 70g of β-hydroxyethyl (meth)acrylate dissolved in 0.5g of phenothiazine dropwise within 30 minutes, and control the temperature of the system in the reaction bottle not to exceed 80°C. After the dropwise addition, maintain the system at 65°C to 70°C After about 2.5 hours, add 280g of styrene, and then l...
