Embodiment 1
[0035] A rubber compound for asphalt-based waterproofing system is prepared by the following method:
[0036](1) Mixing, adding asphalt into the reaction kettle by metering, and setting the temperature at 170°C;
[0037] (2) Modification, put the modifier into the reaction kettle, control the temperature at 165°C, and stir for 2 hours;
[0038] (3) Cross-linking, put 10g of tribasic lead sulfate and 10g of sulfur into the reactor, and disperse for 30min;
[0039] (4) Viscosity reduction, pass the above rubber material through the colloid mill, set the colloid mill gap to 3mm, then add 10g of polyethylene wax to the system, melt and disperse for 30min;
[0040] (5) Dispersion: Add 15kg of talcum powder, and make a rubber compound after uniform dispersion, which is counted as A1.
[0041] Described asphalt is 90# asphalt 30kg, 200# asphalt 5kg.
[0042] The modifier is 1kg of SBS, 1kg of SBR, 2kg of IIR, and 1kg of SIS; wherein the weight ratio among SBS, SBR, IIR and SIS is ...
Embodiment 2
[0044] The difference between this example and Invention Example 1 lies in that the weight of each component is different, as described below.
