[0024] Example 1:
[0025] The A component is:
[0026] Polyether polyol 1#: 45
[0027] CPOP-290E: 33
[0028] Y1030: 20
[0029] Water: 1.5
[0030] B8002: 0.5
[0031] The B component is:
[0032] Polyether polyol 1#: 25
[0033] ED-28: 11
[0034] 1,4-Butanediol: 2
[0035] Pure MDI: 50
[0036] Liquefaction MDI: 10
[0037] SK1900: 2
[0038] The C component is:
[0039] DMEA: 20
[0040] A300: 80
[0041] Among them, polyether polyol 1# is a polyoxypropylene triol with glycerin as the initiator, primary hydroxyl content ≥80%, number average molecular weight of 9000, and ethylene oxide end-capped polyoxypropylene triol.
[0042] A component material: first put the polyether polyol 1#, CPOP-290E, Y1030 based on the formula amount into the mixing kettle and stir, then add the measured water and B8002 in sequence, at room temperature, the speed is 80 rpm Minutes, stirring for 1.5 hours, then the qualified product of component A is obtained;
[0043] B component material: Put the polyether polyol 1...
