Embodiment 1
[0033] Prepare SBS elastic waterproof coating by the following steps:
[0034] 1) To 100 parts by weight of commercially available 90 # Add 6 parts by weight of commercially available SBS produced by Yueyang Petrochemical to Liaohe heavy traffic asphalt, and then add 10 parts by weight of commercially available furfural extraction oil. Cool down to 140°C and set aside;
[0035] 2) Add 10 parts by weight of sodium bentonite to 100 parts by weight of water, heat up to 50°C while stirring, then add 5 parts by weight of emulsifier and acid-base regulator mixture (which contains 55% sodium lauryl sulfate Emulsifier, 30% melamine and 15% sodium hydroxide) for subsequent use;
[0036] 3) The two compositions prepared in step 1) and step 2) are emulsified with a three-stage pipeline emulsifier produced by Shanghai Weiyu Electromechanical Manufacturing Co., Ltd.;
[0037] 4) Add 10 parts by weight of commercially available styrene-butadiene latex produced by Qilu Petrochemical to th...
Embodiment 2
[0039] Prepare SBS elastic waterproof coating by the following steps:
[0040] 1) To 100 parts by weight of commercially available 90 # Add 10 parts by weight of commercially available Qilu Petrochemical SBS to the Liaohe heavy traffic asphalt, and then add 15 parts by weight of commercially available furfural extraction oil. When the temperature is raised to 180°C, grind it with a colloid mill until it is completely uniformly dispersed, and then cool down to 150℃, standby;
[0041] 2) Add 15 parts by weight of sodium bentonite to 100 parts by weight of water, heat up to 60°C while stirring, then add 8 parts by weight of emulsifier and acid-base regulator mixture (which contains 70% sodium lauryl sulfate Emulsifier, 15% melamine and 15% sodium hydroxide) for subsequent use;
[0042] 3) The two compositions prepared in step 1) and step 2) are emulsified with a three-stage pipeline emulsifier produced by Shanghai Weiyu Electromechanical Manufacturing Co., Ltd.;
[0043] 4) Ad...
