Abstract

The invention provides a water-based binder applied to a waterproofing project of a building structure. The water-based binder is prepared from the following raw material components in parts by weight: 30 to 45 parts of emulsified asphalt, 10 to 20 parts of neoprene latex, 10 to 20 parts of chlorinated paraffin, 8 to 25 parts of filler, 15 to 25 parts of VAE (Vinyl Acetate-Ethylene Emulsion), 0.4 to 0.6 part of silane coupling agent, 0.2 to 0.5 part of defoamer, 0.3 to 0.6 part of emulsifier and 0.2 to 0.4 part of fungicide. According to the water-based binder provided by the invention, good binding property is realized, the binding property strength on a dry base surface is 1.0 to 1.2MPa (100 percent cohesive failure), and the binding property strength on a moisture base surface is 1.0 to 1.1MPa (100 percent cohesive failure). The water-based binder provided by the invention is high in high-low-temperature resistance.

Description

technical field [0001] The invention relates to a water-based adhesive used in waterproof engineering of building structures and a preparation method thereof, belonging to the field of waterproof materials. Background technique [0002] Waterproof membranes are widely used in domestic and foreign buildings due to their simple structure, less maintenance workload, long service life, and long-term waterproof effect in one construction. However, when there are cracks in the building base or deformation of the building structure, it is still easy to cause the waterproof layer to crack. In areas with complex structures, it is difficult to achieve full stickiness, which leads to the phenomenon of water stringing. At this time, an adhesive is required for bonding. [0003] Adhesives are important raw materials used in building structure waterproofing projects. The adhesive is not only the bonding layer between the cladding material and the layer, which can maintain the bonding a...
