Problems solved by technology

The polymer coatings currently used all use water-emulsified emulsion-based water-emulsion coatings. It uses cold construction, but its solid content is low, generally not exceeding (60-70%), and the thickness of each coating must be cured Conditions are limited, it is impossible to be very thick, and the film needs to be painted multiple times. Under humid conditions, the water in the emulsion cannot be volatilized, so it cannot be cured, which is very inconvenient
To meet the requirements of waterproof technical specifications, the thickness must be painted multiple times, which greatly affects the efficacy
limited scope of use

Abstract

The invention belongs to the technical field of waterproof coatings, and in particular relates to a rapid macromolecule machine-sprayable demulsification solidification filming waterproof coating and a preparation method thereof. The rapid macromolecule machine-sprayable demulsification solidification filming waterproof coating consists of a component A and a component B, wherein the component A consists of the following components in percentage by weight: 25-35% of macromolecule, 20-40% of water, 1-5% of an emulsifying agent, 20-50% of rubber latex and 0-5% of packing; the component B consists of the following components in percentage by weight: 30-40% of a demulsification agent and 60-70% of water. The waterproof coating can be rapidly demulsified and dehydrated to form a coating waterproof protecting layer which is excellent in waterproof property, after the coating is sprayed, the coated layer is dried into a film, the high elasticity, the low temperature flexibility and the aging resistance of a rubber material are maintained, and the coating has the advantages of high puncture force resistance, water permeation prevention, temperature resistance, freezing resistance, chemical corrosion resistance, cracking resistance and the like.

Description

technical field [0001] The invention belongs to the technical field of waterproof coatings, in particular to a polymer machine-sprayable rapid demulsification and solidification film-forming waterproof coating and a preparation method thereof. Background technique [0002] The current waterproof materials are mainly waterproof membranes and waterproof coatings. [0003] Modified asphalt membranes, such as SBS and APP membranes, which are more popular in the waterproof material market at present, require flame spray guns to carry out on-site surface melting, require open flames, have high technical requirements, and easily cause the surface hot melt adhesive to coke. The width of the membrane is only one meter, and there are many overlaps during laying. Due to the shape requirements of the base layer, it needs to be cut, and the amount of overlap is increased, which is likely to cause hidden dangers of joint waterproofing; self-adhesive asphalt waterproof membranes have weak ...
