Problems solved by technology

But another problem has arisen from this, that is, once the waterproof layer produces small holes or cracks in a certain part and leaks water, there will be water channeling under the waterproof layer, resulting in multiple leaks in the room, and it is difficult to find the leak. The source of the leakage brings great difficulty to the repair work

Abstract

The invention discloses a machine-sprayable rapid demulsification, solidification, film-forming and creeping waterproof coating and a preparation method thereof, which belong to the technical field of waterproof coatings. It is formed by dehydration and solidification after atomization and mixing of A and B components in the air. According to weight percentage, component A includes: thermoplastic elastomer polymer 5%-20%, asphalt 20%-50%, water 30%- 50%, emulsifier 1%-5%, rubber latex 5-20%, filler 0%-20%; B component is composed of demulsifier 30%-40% and water 60%-70%. The waterproof coating overcomes the disadvantages of ordinary elastomers such as rapid aging and fatigue caused by stretching in a high-stress state for a long time, and always maintains good viscosity and rebonding ability, completely solves the problem of internal stress in the waterproof layer, and makes the waterproof layer continue to stick. It has the characteristics of strong knot ability, high elongation rate and good low temperature flexibility. Its material has good bonding performance, good heat resistance, low temperature flexibility, and the creep performance under shear state is above 0.1N / mm.

Description

technical field [0001] The invention belongs to the technical field of waterproof coatings, and in particular relates to a non-curing waterproof coating capable of rapid demulsification, solidification, and film formation that can be sprayed by a machine and a preparation method thereof. Background technique [0002] 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 coil 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; Its water resistance is poor, and it is easy to cause waterproof failure due to degumming, so the bonding of po...
