Example Embodiment
[0033] Example 1
[0034] (1) Preparation of modified carbon nanotubes: Place the carbon nanotubes in concentrated nitric acid, soak them at 30℃ for 6h, take them out and wash them until they are neutral; then put them in silane coupling agent KH-560, and stir at 60℃ After 2h, clean and dry to obtain modified carbon nanotubes.
[0035] (2) Preparation of component B of polyurethane stadium material: Put 35kg of polyether polyol VOANOL CP-6001, 14kg of 325 mesh talc, 8kg of iron oxide green 5605 and 2kg of dispersant YCK-2330 into the reactor and mix at 800r / min. Stir for 13min, add 35kg44C, continue stirring at 800r / min speed, react at 75℃ for 3h, take a sample and check that the NCO content is 10.29 qualified, then cool to 65℃, then add 3kg modified carbon nanotubes at 800r / min Stir at the speed for 18 minutes, and finally add 1 kg of organic bismuth catalyst Kat22 and 2 kg of defoamer RJ-4040, and stir at 1800 r / min for 25 minutes to obtain the carbon nanotube modified polyureth...
