Example Embodiment
[0021] Example 1
[0022] 1. Put 6 parts of cyclohexane, 2 parts of heptane, and 0.5 parts of styrene-butadiene rubber in parts by mass in a closed mixer. Stir at 65°C for 1 hour until completely dissolved and cool to room temperature.
[0023] 2. Transfer the above solution to a dispersion mixer, add 5 parts of butyl acrylate, 3 parts of isodecyl acrylate, 0.8 part of acrylic resin, 0.01 part of polyether modified polydimethylsiloxane, and stir for 30 minutes .
[0024] 3. Add 4 parts of color paste, 0.03 part of a mixture of 52% polyacrylate and 48% alkylbenzene, 0.22 part of α-hydroxyalkyl phenone photoinitiator in the above dispersing mixer, stir for 10 minutes, and discharge Immediately.
[0025] 4. Brush the above-mentioned ink on the clean side of the tire, and use UV radiation to cure it into a coating film. Test the performance of the coating film according to the national standard, as shown in Table 1.
Example Embodiment
