[0052] A preparation method based on BIPV technology-specific modified asphalt waterproofing membrane, comprising the following steps:
[0053] 1) Add petroleum asphalt into the reactor, heat and stir at 180~190°C for dehydration;
[0054] 2) According to the ratio described in claim 1, add residual oil, SBS rubber, and silicone rubber in sequence, and keep stirring for 2 hours;
[0055] 3) Pour the processed material in step 2) into the colloid mill for grinding, and grind it in a cycle for three times, and continue to stir and disperse for 30-60 minutes after grinding;
[0056] 4) Cool down to about 160°C, add coumarone resin, and keep stirring for 1 hour;
[0057] 5) Add UV absorber, antioxidant, talcum powder, stir and mix evenly, pour into oil immersion tank;
[0058] 6) Unfold the base layer of the glass fiber reinforced polyester felt, put it into the oil immersion tank, and carry out oil immersion coating;
[0059] 7) Control the thickness of the oil-immersed coatin...
Embodiment 1
[0067] Add 30g of petroleum asphalt into the reactor, heat and stir at 180~190°C for dehydration, add 20g of residual oil, 5g of star-shaped SBS rubber, and 2g of silicone rubber in sequence, keep stirring for 2 hours, then pour it into a colloid mill and grind it for three times. After grinding, continue to stir for 30-60 minutes, lower the temperature to 160°C, add 5 coumarone resin, keep stirring for 1 hour, then add 0.1g of antioxidant di-tert-butyl p-cresol, 5g of anti-ultraviolet absorber Mg-Al-based LDHs compound , 20g talcum powder, stir evenly, pour the SBS modified asphalt oil immersion material into the oil immersion tank, unfold the tire base material, put it into the oil immersion tank, apply oil immersion, cool, and cover.
[0068] The upper surface of the waterproof material layer is coated with shale isolation film, the material thickness of the waterproof layer is 1mm, the lower surface of the waterproof reinforcement layer is coated with hot-melt PE film, the ...
