Example Embodiment
[0019] Example 1
[0020] An elastomer (SBS) modified bitumen waterproofing membrane, prepared from the following parts by weight of raw materials:
[0021] 20 parts of 10# asphalt, 40 parts of 100# asphalt, 11 parts of engine oil, 12 parts of SBS (elastomer), 17 parts of talc.
Example Embodiment
[0022] Example 2
[0023] A production process of the elastomer modified bitumen waterproof membrane described in Example 1, including the following steps:
[0024] (1) Mixing ingredients
[0025] 1. Prepare the weighed raw materials according to the above formula, and the raw materials should be sorted and placed neatly;
[0026] 2. After measuring 10# bitumen through the metering tank, drive it into the batching tank, add engine oil when the temperature rises to 160±5℃, add elastomer SBS when the temperature rises to 180±5℃, and start the colloid mill while stirring 2 -3 times, stirring for 80 minutes to 100 minutes, the temperature is controlled at 180-190℃, when the temperature rises to 200℃-210℃, add talcum powder, stir for half an hour, check that the ingredients are fully stirred, and the temperature is controlled at this time Between 170-180℃, and take samples for semi-finished product testing;
[0027] In addition, after heating 100# bitumen to 175-185℃, directly put it into ...
