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-spraying quick-demulsifying solidification film formation creep waterproof coating and a preparation method thereof, belonging to the technical field of waterproof coating. The waterproof coating is formed from the components A and B by atomization mixing in air and dehydration curing, wherein the component A comprises the following components in percentage by weight: 5-20% of thermoplastic elastomer polymer, 20-50% of asphalt, 30-50% of water, 1-5% of emulsifier, 5-20% of rubber latex and 0-20% of filler; the component B consists of the following components in percentage by weight: 30-40% of demulsifier and 60-70% of water. The waterproof coating overcomes the shortcomings of a common elastomer, such as quick aging in a high-stress state for a long time, stretching fatigue and the like, and always keeps good viscosity and re-bonding ability; the problem of internal stress of a waterproof layer is thoroughly solved, so that the waterproof layer has the characteristics of strong sustained bonding ability, high elongation and low-temperature flexibility; the material has good adhesive property, good heat resistance and good low-temperature flexibility, and the creep property in a shear state can exceed 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...
