Water leakage manifestation type roof covering coating

Abstract

The invention discloses a water leakage manifestation type roof covering coating, and belongs to the field of roof waterproofness, the composite coating has the advantage of accurately displaying water leakage points by changing the composite coating, and when a waterproof material is damaged and cracks are generated, rainwater permeates downwards to wet powder pigment in a water absorption channel firstly, and then the water leakage points can be accurately displayed. When the roof leaks water, the rainwater permeates downwards into the shell of the water generating ball to dissolve the effervescent tablets to generate a large amount of carbon dioxide gas, and bubbles with colors are generated when the gas overflows outwards, so that the water leakage point is accurately displayed under the dual effects of the colors and the bubbles, and constructors can conveniently find the water leakage point timely and accurately; according to the roof water leakage early warning device, the effect of early warning is achieved before roof water leakage, roof water leakage is effectively avoided, in addition, a large amount of gas can further enable the composite coating to generate bumps, and water leakage points are further accurately displayed.

Description

technical field [0001] The present invention relates to the field of roof waterproofing, in particular to a water-leakage revealing roof covering coating. Background technique [0002] The waterproof membrane is mainly used for building walls, roofs, tunnels, highways, landfills, etc. It is a flexible building material product that can be rolled into a roll to resist external rainwater and groundwater leakage. There is no leakage connection between the building and the building, which is the first barrier of the entire project waterproofing and plays a vital role in the entire project. [0003] The roof is the enclosure and load-bearing structure that covers the uppermost layer of the house, and one of its main functions is to "shield from the wind and rain". Roofs can be divided into flat roofs and sloping roofs according to different drainage slopes. There was a time when the roof leakage rate remained high in housing construction, which seriously affected the use functi...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a leak-proof roof covering coating. Compared with the defect that the existing waterproof materials cannot accurately display the leak point, this design has the advantage of accurately displaying the leak point. When the material itself is damaged and cracks are generated, the effervescent tablet will generate a large amount of gas through the downward penetration of water, and at the same time, the penetration of water will wet the powder pigment, thus showing the leak point under the dual effects of color and air bubbles
