[0045] Example 1
[0046] 1. Preparation of hydroxyl-terminated prepolymer
[0047] Put 75 parts by weight of hydroxyl-terminated polyether polyol (functionality 2~3) in the reactor, stir and heat to 80~90℃, add 8 parts by weight of diphenylmethane diisocyanate (functionality 2~ 2.1) The reaction is kept under stirring for 0.5-hour, until the reaction is complete, and then cooled to normal temperature.
[0048] 2. Preparation of component A
[0049] Take 20 parts by weight of the hydroxyl-terminated prepolymer prepared in the above step 1 and put it into a mixer, add 15 parts by weight of hydroxyl-terminated polyol (functionality 2 to 4), 18 parts by weight of castor oil, and diisophthalic acid 7 parts by weight of octyl ester, 40 parts by weight of calcium carbonate, 20 parts by weight of quartz sand, 0.04 parts by weight of catalyst, 0.02 parts by weight of antioxidant, heating and stirring for mixing for 1 to 2 hours.
[0050] The above-prepared component A and 20 parts by weig...
