Rubberized-plasticized non-solidified asphalt paint

Abstract

The invention discloses a rubberized-plasticized non-solidified asphalt paint. The paint consists of 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 a styrene-butadiene segmented copolymer, 3.5-10 parts of butadiene styrene rubber SBR, 2-10 parts of plastic, 0.5-3 parts of a surfactant and 0.5-5 parts of plasticizer. The rubberized-plasticized non-solidified asphalt paint can never be hardened, is greater than 99% in solid content and free from a volatile matter, and the asphalt paint, after construction, is constantly kept in an original colloidal state; the asphalt paint is strong in craking property, and can be constructed on a damp base surface and be stuck with any foreign material; the asphalt paint can be simultaneously used with other waterproof materials to form a composite waterproof layer, thus enhancing the waterproof effect, and the asphalt paint is excellent in flexibility, ductility and deformation following property; the asphalt paint, which is strong in self-healing performance, can self-heal even in case of damage of the waterproof layer in the construction, so as to keep a complete waterproof layer; the asphalt paint is simple to construct, and supports scraping construction, spraying construction and grouting construction. The asphalt paint can construct at a normal temperature and at minus 10 DEG C.

Description

technical field [0001] The invention relates to a rubber-plasticized non-curing asphalt paint. Background technique [0002] Waterproof engineering is the key to ensure that the structure of the building is free from water erosion and the interior space is free from flooding, and excellent waterproof materials are the only means to achieve this goal. Conventional waterproof coiled materials and waterproof coatings are flexible waterproof materials. This type of material is greatly affected by the deformation of the base layer. Once the base layer cracks, the waterproof layer is easily affected by the cracks, causing water seepage, aging or fatigue damage to the waterproof layer. Even with empty paving, point sticking or strip paving, it is difficult to ensure that the waterproof layer will produce small cavities or micro-cracks in a certain part, causing water leakage and water channeling, which seriously affects the quality of construction projects. Therefore, the research...

AI Technical Summary

Problems solved by technology

[0006] At present, the existing waterproof materials are all film-forming and molding products. The shortcomings are: 1. The coating film is not suitable for structural deformation. The limitation of extensibility cannot adapt to the cyclic deformation of the base layer, resulting in damage to the waterproof coating film; second, the adhesion between the coating film and the base layer decays too fast, such as the adhesion between the coating film and the base layer is not firm or the rapid attenuation and the base layer fall off, the coating It will lose the waterproof and anti-corrosion function, resulting in leakage and water channeling, which seriously affects the use effect of the waterproof coating film.
