The non-cured rubber asphalt waterproof paint belongs to a solvent-free non-reactive non-film-forming single-component creep-deformation paint, and has good bonding capability with base materials such as metal, nonmetal, concrete and the like. The waterproof coating has the characteristics of no need of maintenance, one-time construction, capability of achieving construction thickness, excellent composite effect with the asphalt coiled material and the like, thereby being widely accepted in the industry and being widely applied to waterproofing of municipal works, subway tunnels, dams, pools, road bridges, roofs, bathroom rooms, underground parts and the like.

However, from the overall situation in China, the product performance is still greatly different from that of the product at abroad, such as high heat resistance and low viscosity, the spraying construction can be performed generally only by heating to 150-200 ℃, the product slides after being compounded with a coiled material at a vertical surface part, smoke volatilization is large in the production and spraying processes, guns are easy to block during the spraying construction, viscoelastic paste is not durable, and the like. This has also been confirmed in recent years by several published literature reports, such as:

the invention discloses a rubber-plastic non-cured asphalt coating, which is disclosed in document 1 and having a patent name of 'a rubber-plastic non-cured asphalt coating' of Chinese patent application No. 2013102912341, and comprises the following components in parts by weight: 30-50 parts of petroleum asphalt, 25-40 parts of waste rubber powder, 5-20 parts of rubber oil, 2-10 parts of styrene-butadiene block copolymer, 3.5-10 parts of Styrene Butadiene Rubber (SBR), 2-10 parts of plastic, 0.5-3 parts of surfactant and 0.5-5 parts of plasticizer. The disclosure thereof fully demonstrates the addition of crumb rubber and the amount thereof is considerable.

In document 2, chinese patent application No. 2018105081018, entitled "a non-cured rubber asphalt waterproof coating", discloses a novel waterproof material with creep property, which is a non-cured rubber asphalt waterproof coating that uses rubber powder, asphalt and special additives as main raw materials and keeps a sticky paste for a long time in an application state. The coating can seal cracks and capillary holes of a base layer, can adapt to the contact of a complex construction operation surface and air, can not be cured for a long time, always keeps the characteristic of sticky colloid, has strong self-healing capability, can be sticky when being touched and is difficult to peel, and still has good bonding performance at the temperature of minus 20 ℃. Due to the viscosity of the creep material, the capillary holes and cracks of the base layer can be well sealed, the problem of water channeling of the waterproof layer is solved, and the waterproof reliability is greatly improved; can also solve the problem of compatibility when the existing waterproof coiled material and waterproof paint are used in a compounding way.
