Reaction-enhanced pre-paved waterproof coiled material and preparation method thereof

Abstract

The invention provides a reaction-enhanced pre-laid waterproof roll and a preparation method thereof. The waterproof roll is composed of a reaction-enhanced combined protective layer, a self-adhesive layer, a main material layer, and / or an adhesive, and / or an isolating layer. Wherein the reaction type reinforced combined protective film is composed of polyvinyl alcohol, solid epoxy resin, modified epoxy resin, filler and auxiliaries, and the structure of the reaction type reinforced combined protective film is a non-woven fabric with the thickness of 0.5 mm-5 mm, a film with the thickness of 0.2 mm-2 mm or a layered structure with the thickness of 0.2 mm-5 mm formed by compounding the film and the non-woven fabric. The problems of foot sticking on the surface of the coiled material, difficulty in construction, reduction of bonding strength with post-poured concrete due to the action of rainwater, dust, silt and ultraviolet aging and the like in the building waterproof construction process can be avoided, the service life of the pre-paved waterproof material is prolonged, the waterproof safety of building engineering is greatly improved, resource waste is reduced, and the construction cost is reduced. Wide application prospects are realized.

Description

technical field [0001] The invention discloses and relates to the technical field of novel building waterproof materials, in particular to a reaction-enhanced pre-laid waterproofing membrane and a preparation method thereof. Background technique [0002] Construction safety is closely related to the national economy and people's livelihood, and has always attracted much attention. The same life span of building envelope materials and main structures has always been the focus of attention in the field of building safety. As a layer of protective outerwear for buildings, the performance of waterproof materials directly affects the service life of buildings. [0003] At present, there are many kinds of waterproof materials. According to different construction methods, waterproofing membranes can be divided into asphalt waterproofing membranes, synthetic polymer waterproofing membranes, pre-laid waterproofing membranes, wet-laid waterproofing membranes and self-adhesive waterpr...

AI Technical Summary

Problems solved by technology

Commonly used viscous reducing materials are usually sand or stones. The use of these materials can prevent the self-adhesive layer from sticking to a certain extent, but it will also reduce the adhesion between the waterproof membrane and the post-cast concrete to a certain extent. junction performance

Especially for the asphalt-based polyester tire pre-paved waterproofing membrane, sand is used as the adhesion-reducing layer material, which often makes the bonding strength between the waterproofing material and the post-cast concrete not meet the national standard requirements, which limits the application of this type of material. In addition, during the construction of pre-paved waterproof membranes, it is often encountered that post-cast concrete construction cannot be carried out immediately after laying, and the self-adhesive on the surface is exposed for a long time outside, affected by dust, sand, ultraviolet light aging, etc., and post-cast concrete Significant decrease in cohesive force, unsatisfactory anti-water channeling effect and other problems have seriously affected the application of pre-laid waterproof membranes

[0005] Therefore, a reaction-enhanced pre-applied waterproofing membrane was developed to improve the comprehensive performance of the pre-applied waterproofing membrane and expand the existing pre-applied waterproofing membrane. Its scope of application is of great significance
