preparation example Construction

[0050] A preparation method based on BIPV technology-specific modified asphalt waterproofing membrane, comprising the following steps:

[0051] 1) Add petroleum asphalt into the reactor, heat and stir at 180~190°C for dehydration;

[0052] 2) According to the ratio in claim 1, add residual oil, SBS rubber, and silicone rubber in sequence, and keep stirring for 2 hours;

[0053] 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;

[0054] 4) Cool down to 160°C, add coumarone resin, keep stirring for 1 hour;

[0055] 5) Add ultraviolet absorbers, antioxidants, talcum powder, stir and mix evenly, pour into the oil immersion tank;

[0056] 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;

[0057] 7) Control the thickness of the oil-immersed coating, an...

Embodiment 1

[0065] 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 ultraviolet absorber Mg-Al-based LDHs compound, 20g of talcum powder, stir evenly, pour the SBS modified asphalt oil impregnation material into the oil immersion tank, unfold the tire base material, put it into the oil immersion tank, apply the oil immersion, cool, and cover with film.

[0066] 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...

Abstract

A special modified bitumen waterproofing membrane based on BIPV technology is characterized in that the modified bitumen waterproofing membrane is a three-layer composite structure, which is a waterproof material layer, a weather-resistant layer, and a waterproof reinforcement layer in order from top to bottom. The invention also provides a method for preparing a modified bitumen waterproofing membrane specially based on the BIPV technology, which includes the steps of stirring the bitumen, adding a modifier, grinding, cooling and the like.

Description

technical field [0001] The invention relates to the field of solar energy utilization and waterproof materials, in particular to a special modified asphalt waterproof membrane based on BIPV technology and a preparation method thereof. Background technique [0002] With the depletion of fossil energy and the increasingly prominent problems of environmental pollution, countries have begun to vigorously seek new energy sources. As a new type of environmentally friendly renewable energy, solar energy has always been the focus of attention. As a widely used solar energy conversion technology, solar photovoltaic power generation technology has received strong support from all over the world and is developing more and more rapidly. [0003] The roof of the building has sufficient sunlight, which can be used as a good place for solar power generation, and can reduce the energy consumption of the building itself. At present, there are mainly two ways to combine solar power generati...
