Embodiment 1
[0020] Embodiment 1: Automobile hot-melt pressure-sensitive adhesive component ratio (mass %)
[0021]
[0022] SIS, SEPS, TOTM and antioxidants were weighed in proportion and added to a horizontal kneader that had been preheated for 60 minutes (wall temperature 180°C), kneaded for 40 minutes, and then added proportionally weighed terpene resin, hydrogenated C 5 Petroleum resin, microcrystalline wax, titanium dioxide, and nano fillers were kneaded at high temperature (175°C) for 40 minutes. Pour into a 25cm×15cm×7cm cube box (lined with high-temperature release paper) in a molten state, and wrap it with release paper after cooling.
Embodiment 2
[0023] Embodiment 2: automobile hot-melt pressure-sensitive adhesive component ratio (mass %)
[0024]
[0025]
[0026] SIS, SEPS, TOTM and antioxidants were weighed in proportion and added to a horizontal kneader that had been preheated for 70 minutes (wall temperature 190°C). After kneading for 40 minutes, terpene resin, hydrogenated C 5 Petroleum resin, microcrystalline wax, titanium dioxide, and nano fillers were kneaded at high temperature (170°C) for 50 minutes. Pour into a 25cm×15cm×7cm cube box (lined with high-temperature release paper) in a molten state, and wrap it with release paper after cooling.
Embodiment 3
[0027] Embodiment 3: automobile hot-melt pressure-sensitive adhesive component ratio (mass %)
[0028]
[0029] SIS, SEPS, TOTM and antioxidants were weighed in proportion and added to a horizontal kneader that had been preheated for 60 minutes (wall temperature 180°C), kneaded for 40 minutes and then added proportionally weighed terpene resin, hydrogenated C 5 Petroleum resin, microcrystalline wax, titanium dioxide, and nano fillers were kneaded at high temperature (185°C) for 60 minutes. Pour into a 25cm×15cm×7cm cube box (lined with high-temperature release paper) in a molten state, and wrap it with release paper after cooling.
