Embodiment 1
[0022] A method for preparing a waterproof material for water supply equipment, comprising the following steps:
[0023] a. Mix modified calcium carbonate, fillers, light calcium carbonate and quartz sand, introduce into a pulverizer, pulverize until passing through a 500-mesh sieve, and then use ultrasonic dispersion for 10 minutes to obtain a powder mixture;
[0024] b. Mix organic rubber, polyurethane material, composite material and asphalt, introduce it into a mixer, knead at 380°C for 3 hours, then add a compound emulsifier, cool down to 130°C, and stir for 60 minutes to obtain mixture 1;
[0025] c. Add low-temperature-resistant modifier to mixture 1, stir and heat at 80r / min for 30 minutes, then add powder mixture, and continue stirring for 20 minutes to obtain mixture 2;
[0026] d. Add thickener, water and defoamer to mixture 2, heat and stir at 60°C until it becomes viscous, and the finished product can be obtained.

Embodiment 2
[0035] A method for preparing a waterproof material for water supply equipment, comprising the following steps:
[0036] a. Mix modified calcium carbonate, filler, light calcium carbonate and quartz sand, introduce into a pulverizer, pulverize until passing through a 400-mesh sieve, and then use ultrasonic dispersion for 10 minutes to obtain a powder mixture;
[0037] b. Mix organic rubber, polyurethane material, composite material and asphalt, introduce it into a mixer, knead at 380°C for 2 hours, then add a compound emulsifier, cool down to 130°C, and stir for 40 minutes to obtain mixture 1;
[0038] c. Add low-temperature resistant modifier to mixture 1, stir and heat at 80r / min for 20-30min, then add powder mixture, and continue stirring for 15-20min to obtain mixture 2;
[0039] d. Add thickener, water and defoamer to mixture 2, heat and stir at 60°C until it becomes viscous, and the finished product can be obtained.

Embodiment 3
[0048] A method for preparing a waterproof material for water supply equipment, comprising the following steps:
[0049]a. Mix modified calcium carbonate, filler, light calcium carbonate and quartz sand, introduce into a pulverizer, pulverize until passing through a 500-mesh sieve, and then use ultrasonic dispersion for 15 minutes to obtain a powder mixture;
[0050] b. Mix organic rubber, polyurethane material, composite material and asphalt, introduce it into a mixer, knead at 460°C for 3 hours, then add a compound emulsifier, cool down to 160°C, and stir for 60 minutes to obtain mixture 1;
[0051] c. Add a low-temperature resistant modifier to mixture 1, stir and heat at a speed of 100r / min for 30 minutes, then add the powder mixture, and continue stirring for 20 minutes to obtain mixture 2;
[0052] d. Add thickener, water and defoamer to mixture 2, heat and stir at 65°C until it becomes viscous, and the finished product can be obtained.
