[0040] In the above-mentioned preparation method, each raw material is weighed according to the above-mentioned mass proportion, comprising the following steps:
[0041] (1) Add weighed water into the heat preservation container, stir and heat up to 60±5°C and keep it warm, add stabilizer, emulsifier, sodium hydroxide during stirring, and stir evenly to make a surfactant solution, 60±5°C ℃ heat preservation standby;
[0042] (2) Pump the rubber oil into the reaction vessel through the heat preservation pipeline, stir and heat up to the temperature of the material at 140±5°C and heat and stir for 20 minutes. During the heat preservation and stirring process, put in the weighed petroleum resin, terpene resin, emulsifier, After antioxidants and pigments, stir at 140±5°C for 1 hour, add styrene-butadiene rubber during the stirring process, heat up to 180±5°C and stir for 3 hours to form a uniform liquid, cool down to 120°C, filter and discharge to Stir and keep warm in the heat p...
