Abstract

The invention discloses water-based non-cured rubber asphalt waterproof paint, and relates to the field of waterproof paint. The water-based non-cured rubber asphalt waterproof paint comprises the following components by weight: 2-12 parts of engine oil, 2-20 parts of aromatic oil, 3-7 parts of naphthenic oil, 1-5 parts of SBR, 1-3 parts of SBS, 25-40 parts of asphalt, 1-6 parts of tackifying resin, 0.5-2 parts of a plasticizer, 2-4 parts of an asphalt emulsifier, 30-40 parts of water, 3-10 parts of filler, 0.1-0.5 part of a dispersion agent, 5-25 parts of latex and 1-10 parts of tackifying emulsions. According to the technical scheme, when the water-based non-cured rubber asphalt waterproof paint is adopted for construction, heating is not needed, instantaneous forming is achieved, construction can be conducted on a wet substrate, and the water-based non-cured rubber asphalt waterproof paint has very excellent adhesive strength and self-healing performance, is energy-saving and environmentally friendly, and can improve the comprehensive waterproof quality of a building and can shorten a construction period; and a material has an excellent creep property and excellent stripping quality, adhesion and heat resistance.

Description

technical field [0001] The invention relates to the field of waterproof coatings, in particular to a water-based non-curing rubber asphalt waterproof coating and a production process thereof. Background technique [0002] Non-curing rubber asphalt waterproof coating is a kind of waterproof coating with "never curing" performance. This product has the characteristics of high solid content, strong adhesion, good creep performance, good self-healing performance and good fatigue resistance. The development has been particularly rapid in the past few years. However, in the actual application process, the material needs to be heated to a very high temperature to reach a hot melt state before construction. On the one hand, the high-temperature heating caused the reduction of the material properties, and on the other hand, the construction site was full of smoke, which caused damage to the health of workers. At the same time, there are also potential safety hazards such as explosi...
