Self-adhering water-proof coiled material and processing method thereof

Abstract

The invention relates to a self-adhered waterproofing membrane, which includes creeping base material and matrix layer, wherein the creeping base material includes: 50-100 portion by weight of water; 15-40 portion by weight of water acrylamide; 0.02-0.5 portion by weight of water bis-acrylamide; 0.5-30 portion by weight of water triethanolamine; 10-30 portion by weight of 0.1-1.0 percent aqueous ammonia persulfate. The invention also provides a processing method for self-adhered waterproofing membrane, which includes the following steps: laying of matrix layer, the matrix material is flatly layered in the production groove, and is moistened by clean water; preparation of the creeping base material, each material is mixed according a certain proportion; forming and curing of the creeping base material, the mixed material is poured into the production groove to flat the liquid surface until the reaction is completed and the material is cured; laying of isolating film, an isolating film is laid on the surface of the cured material, followed by rolling up and packaging. The self-adhered waterproofing membrane of the invention has good bonding property with wet base surface, and the self-creeping of the invention can eliminate stress influence to base surface and also has self-healing function.

Description

technical field [0001] The invention relates to a waterproof material and a processing method thereof, in particular to a self-adhesive waterproof coiled material and a processing method thereof. Background technique [0002] Building waterproofing is very critical to the quality of the building. The usual waterproofing treatment is to lay waterproof membranes on the buildings. The existing waterproof membranes are mostly self-adhesive rubber asphalt waterproofing membranes. The composition formula of self-adhesive rubber asphalt waterproofing membranes ( parts by weight) is: [0003] No. 10 oxidized asphalt 45 [0004] 200 mesh talcum powder 40 [0005] SBS (Styrene-Butadiene-Styrene Block Copolymer) 5 [0006] SBR (styrene-butadiene rubber) 10 [0007] The processing method of this self-adhesive rubber asphalt waterproof membrane is: [0008] 1. Put the modified materials (SBS, SBR) and filler materials (talc powder) directly into and evenly disperse them into the asp...

AI Technical Summary

Problems solved by technology

[0011] 1. The adhesion to the wet base surface is not firm;

[0012] 2. The properties of the adhesive and the coil body are not synchronized, and the overlapping joints are prone to detachment when exposed to water;

[0013] 3. After being pierced by a hard object, the coil does not have the function of self-repair;

[0014] 4. If the coil is broken, the damaged part is easy to channel water under the coil;

[0015] 5. The coiled material with good bonding performance cannot resolve the stress transfer of the base layer, and the coil body is prone to local rapid aging and damage at the stress change of the base layer;

[0016] 6. The production equipment and steps are complicated, and the production materials need to be heated to a molten state;

[0017] 7. The amount of raw materials used in petroleum products is large
