Problems solved by technology

Mentioned in the description of this document, the technical problem to be solved is the water channeling and water channeling of "sandwich biscuit type" between the self-adhesive membrane waterproof layer and the base layer (or structural layer) in the wet laying method in the prior art. Water leakage can also solve the hollowing of the waterproof layer caused by workers' irregular construction operations
The non-curing rubber asphalt coating in the above scheme needs to be applied after heating, and the solvent in the construction environment has a large amount of volatilization, which requires high fire protection; the surface of the base must be dry, and construction cannot be carried out under wet conditions
[0003] The improved technical solution in the prior art also includes the use of hot-melt adhesives to bond waterproof membranes, but the use of hot-melt adhesives also requires heating, and the requirements for the cleanliness and dryness of the waterproof construction surface are higher, and the construction process is cumbersome.
[0004] In addition, although the joints of the coiled material have been treated with waterproofing, after a long period of use, water seepage is prone to occur at the joints, which further affects the bonding stability between the coiled material and the substrate

Abstract

The invention discloses a construction method of a water-borne non-curing coating and coiled composite waterproof system. The construction method comprises the following steps: S1, spraying a water-borne non-curing coating on a base material layer; S2, pasting a waterproof coiled material on the surface of the coating of the S1. According to the construction method of the water-borne non-curing coating and coiled composite waterproof system, firstly spraying the water-borne non-curing coating on the base material surface, forming a whole waterproof layer with no joint on the surface of the base material, and then directly bonding the waterproof coiled material on an upper end of the water-borne non-curing coating by using adhesion property of the water-borne non-curing coating, so as to increase the rigidity of the waterproof system. Compared with the prior art, no heat treatment is needed in the construction process, and the dry and humidity degree of the construction surface is not required, so that cold construction and construction in rainy day can be realized.

Description

technical field [0001] The invention relates to the technical field of waterproof construction, in particular to a construction method of a composite waterproof system of water-based non-curing paint and coiled material. Background technique [0002] Non-curing rubber asphalt water-based non-curing coatings and coatings have good adhesion, extensibility, self-healing properties, good low-temperature flexibility, and can achieve seamless construction in waterproof construction. It is a new type of asphalt waterproof material. In the current roofing and underground waterproofing works, there are relatively clear regulations on the above-mentioned waterproofing materials, building waterproofing structures, construction methods, and project acceptance. CN103465540A discloses a construction method of a non-curing rubber asphalt coating and coiled material composite waterproof layer, which includes heating the non-curing rubber asphalt coating to a specified temperature, and apply...
