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...

[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%;

Abstract

The invention relates to non-oil-penetrating type creep rubber waterproof coating. The coating is characterized in that the coating includes, by mass, 3-20% of butyl rubber, 5-10% of styrene-butadiene rubber, 35-60% of rubber powder, 5-20% of a polymer modifying agent, 5-25% of asphalt and 5-15% of an inorganic modifying material; the polymer modifying agent is one of or a mixture of materials selected from a group consisting of polypropylene, polystyrene, bis(triethoxysilylpropyl) tetrasulfide, bis(triethoxysilylpropyl) disulfide, gamma-mercaptopropyl trimethoxysilane, oxidized polyethylene wax and ethylene-vinyl acetate copolymer wax; and the inorganic modifying material is glass microbeads, precipitated calcium carbonate powder, talcum powder, ground calcium carbonate powder or a mixture thereof. The actually measured VOC content of the coating is less than 10, and no oil is penetrated at 60 DEG C.

Description

technical field [0001] The invention relates to a non-oil-permeable creeping rubber waterproof coating and a preparation method thereof, which are applied to the construction waterproofing and leakage plugging and repairing industries. [0002] technical background [0003] At present, architectural waterproof coatings mainly include epoxy coatings, asphalt modified coatings, and polyurethane coatings. [0004] Among them, asphalt modified coatings have appeared non-cured rubber asphalt coatings in recent years. Most of them are high-flash point solvent oil and a small amount of rubber powder added to the modified asphalt coatings in large quantities, and formed by physical heating and mixing. The solid content of these non-cured coatings The test was carried out at 105 degrees by weighing with a thermobalance, but in reality, a large amount of high flash point solvent oil (flash point greater than 105 degrees) was added. Such a product is used in actual engineering, and the ...
