Embodiment 1

[0042] Please see figure 1 and figure 2 , a polymer self-adhesive waterproof membrane wet-laying process provided in the embodiment of the present application, comprising the following steps:

[0043] Include the following steps:

[0044] S1: Clean the surface of the base layer and fully wet the base layer, but there should be no clear water;

[0045] S2: laying a layer of hot-melt pressure-sensitive adhesive film on the surface of the base;

[0046] S3: Lay the first coil on the hot-melt pressure-sensitive adhesive film;

[0047] S41: after the laying of the first coil is completed, respectively uncover the isolation films of the third lap, the fifth lap and the sixth lap on the first coil;

[0048] S42: Uncover the separation film of the first lap, the second lap and the fourth lap on the second coil;

[0049] S43: The first overlapping edge of the second coil is overlapped with the third overlapping edge of the first coil; the second overlapping edge of the second coi...

Abstract

The embodiment of the invention provides a high-molecular self-adhesive waterproof coiled material wet laying process. The process comprises the following steps that S1, the surface of a base layer iscleaned, the base layer is sufficiently wet, but bright water is not allowed; S2, a layer of hot-melt pressure-sensitive adhesive film is laid on the surface of the base layer; S3, a first coiled material is laid on the hot-melt pressure-sensitive adhesive film; S4, a second coiled material is in lap joint with the first coiled material and is pressed in the laying direction so that the second coiled material can be laid on the hot-melt pressure-sensitive adhesive film; S5, after the first coiled material and the second coiled material are laid, the lap joint is covered and sealed by using sealing adhesive tape; and S6, after the first coiled material and the second coiled material are laid, the air at the bottom is exhausted by using roller pressing, and the flatness of the laying surface is guaranteed. According to the laying process, the first coiled material is in lap joint with the second coiled material, in particular, the lap joint edges are connected with the lap joint edges,so that a certain shielding effect on the lap joint is achieved, in cooperation with the sealing adhesive tape at the top, the purpose of preventing leakage is further guaranteed, and the waterproof effect is further achieved.

Description

technical field [0001] This application relates to the technical field of building construction, in particular, to a wet laying process of polymer self-adhesive waterproof membrane. Background technique [0002] The main raw material of the wet-laid waterproof membrane is active substances, and at the same time, appropriate amount of auxiliary materials, anti-aging agents, accelerators and other additives are added, and it is made by mixing and calendering. Waterproof products, the material contains special active substances that can react with cement mortar or plain cement slurry to achieve full adhesion with the base surface or the main body of the structure. [0003] The existing patent CN201510414621 is a wet-laying construction process of polymer self-adhesive waterproof membrane. There will still be some leakage in the waterproof membrane. Contents of the invention [0004] The purpose of the embodiments of the present application is to provide a wet-laying process...
