Embodiment 1
[0036] A non-oil-permeable creep rubber waterproof coating, calculated in mass percentage, its component ratio is as follows:
[0037] Butyl rubber 5%;
[0038] SBR 7%;
[0039] Polymer modifier 8%;
[0040] Asphalt 15%;
[0041] Inorganic modifier 10%;
[0042] Rubber powder 55%;
[0043] The rubber powder is a mixture of reclaimed rubber and nitrile rubber; the asphalt is a mixture of 70# and 90# petroleum asphalt; the polymer modifier is polyethylene, bis(triethoxysilicone propylene) base) tetrasulfide, bis(triethoxysilylpropyl) disulfide, γ-mercaptopropyl trimethoxysilane, oxidized polyethylene wax, ethylene-ethyl acetate copolymerized mixture; the inorganic modification The material is a mixture of vitrified microbeads and light calcium powder.
[0044] In this example, the rubber powder is first modified, and a modifier is added and modified by high pressure or screw extrusion to form modified rubber particles, which are then heated and mixed with other materials t...

[0051] A non-oil-permeable creep rubber waterproof coating, calculated in mass percentage, its component ratio is as follows:
[0052] Butyl rubber 15%;
[0053] SBR 5%;
[0054] Polymer modifier 10%;
[0055] Asphalt 20%;
[0056] Inorganic modifier 10%;
[0057] Rubber powder 40%;
[0058] The rubber powder is a mixture of reclaimed rubber and chloroprene rubber; the asphalt is 90# petroleum asphalt; the polymer modifier is polypropylene, bis(triethoxysilylpropyl) disulfide , a mixture of γ-mercaptopropyl trimethoxysilane; the inorganic modified material is a mixture of vitrified microbeads and light calcium powder.
Embodiment 3
[0060] A non-oil-permeable creep rubber waterproof coating, calculated in mass percentage, its component ratio is as follows:
[0061] Butyl rubber 5%;
[0062] SBR 5%;
[0063] Polymer modifier 15%;
[0064] Asphalt 25%;
[0065] Inorganic modifier 15%;
[0066] Rubber powder 35%;
[0067] The rubber powder is a mixture of reclaimed rubber and chloroprene rubber; the asphalt is 90# petroleum asphalt; the polymer modifier is polystyrene, bis(triethoxysilylpropyl) disulfide compound, γ-mercaptopropyl trimethoxysilane, oxidized polyethylene wax, and ethylene-ethyl acetate copolymer wax; the inorganic modifier is a mixture of vitrified microbeads and light calcium powder.
[0068] The non-oil-permeable creep rubber waterproof coating prepared in the above example was smeared on neutral filter paper, put into an incubator at 60 degrees Celsius for 2 hours, and taken out for testing. There was no oil leakage on the back of the filter paper. And the measured VOC content is les...
