Problems solved by technology

[0003] Although the existing asphalt waterproofing membranes also have a certain degree of elongation, when there are cracks in the base of the building or deformation of the building structure, it is still easy to cause the waterproof layer to crack.
Moreover, in areas with complex structures, it is difficult to achieve full adhesion, resulting in water channeling
Some of the raw materials of the existing non-curing rubber asphalt waterproof coatings are expensive, some materials are not environmentally friendly, the modifiers used have potential safety hazards, and the VOC content is high, which directly restricts the use and promotion of non-curing waterproof coatings.

Abstract

The invention discloses non-curing rubber asphalt waterproof coating and a preparing method thereof, and relates to the technical field of waterproof coating. The coating includes, by mass, 44-54 parts of asphalt, 15-25 parts of naphthenic oil, 2-5 parts of a modifier A, 3-6 parts of a modifier B, 3-6 parts of a modifier C, 2-4 parts of rosin resin, 5-10 parts of SBR, 10-20 parts of ground calciumcarbonate, 1-2 parts of an antioxidant and 2-4 parts of a thickener, with the modifier A being modified polypropylene wax H430. The coating has a creep property and a self-healing property, is non-curing after long-term contact with air, can permanently maintain elastic-plastic colloid, has characteristic of high self-healing capability, instant adhesion after contact, difficult stripping, excellent integrated performance, a low cost and a reduced VOC content, can seal basement layer cracks and capillary openings and can adapt to complex construction operation surfaces.

Description

technical field [0001] The invention relates to the technical field of waterproof coatings, in particular to a non-cured rubber asphalt waterproof coating and a preparation method thereof. Background technique [0002] Due to its mature technology, high level of industrialization, stable performance, convenient construction and simple maintenance of equipment, modified bitumen waterproofing membrane is widely used in domestic and foreign construction. Asphalt waterproof membrane (referred to as asphalt membrane) is a layer of waterproof layer laid on the surface of the building, or between the building base and the decorative surface. An important technical means of service life. Asphalt waterproofing membrane is widely used in industrial and civil buildings at home and abroad because of its simple structure, less maintenance workload, long service life, and long-term waterproofing effect in one construction. [0003] Although the existing asphalt waterproofing membrane al...
