Reactive self-adhered ethylene-propylene-diene monomer waterproof roll

Abstract

The invention relates to a reactive self-adhered ethylene-propylene-diene monomer waterproof roll which consists of a surface waterproof layer, a middle self-adhering layer and a bottom isolating layer, wherein the surface waterproof layer is formed by co-mixing ethylene-propylene-diene monomer rubber, zinc oxide, sulfur, stearic acid, highly wear-resistant carbon black, processing oil and an accelerator DM, the middle self-adhering layer is an active self-adhered sizing material which is formed by co-mixing asphalt, a softener, a tackifier, butyl rubber IIR (Isobutylene-Isoprene Rubber), butadiene styrene rubber, an activator and filler, and the bottom isolating layer is a PET (Polyethylene Terephthalate) thin film. As the middle self-adhering layer which contains asphalt and active macromolecular active components and has the active reactive self-adhered sizing material is arranged in the upper layer on the inner surface of the surface waterproof layer which takes ethylene-propylene-diene monomer as a main material, so that edges of the roll and the roll and the base layer of concrete are directly adhered by the middle self-adhering layer without any adhesives in match. The generated waterproof layer has a service life effect which is equal to that of a main body material, so that the roll is an ideal upgrading product of existing single ethylene-propylene-diene monomer waterproof roll.

Description

technical field [0001] The invention relates to the technical field of waterproof building materials, in particular to a reactive self-adhesive EPDM waterproof roll with good construction performance, mortise-and-mortise cross-linking between the waterproof layer and the base layer after construction, which is not easy to separate, and excellent durability. material. Background technique [0002] The well-known EPDM waterproofing membrane is a single-layer sheet material with excellent water-proof performance and all performance indicators can reach the national first-class waterproof material standard. It is currently widely used in the field of waterproofing engineering at home and abroad. High-grade rubber waterproof membrane. There is no need to use a heat source during construction, and a cold construction process using neoprene as an adhesive can be used. It has the characteristics of simple process, convenient construction, and the immediate working reliability of th...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the existing monolithic EPDM waterproofing membrane that requires special adhesives during construction, and the performance of the resulting waterproof layer is restricted by the adhesive, resulting in higher construction costs and long-term working life. The shortcomings that are difficult to guarantee, provide a reactive self-adhesive type that has an active reactive self-adhesive function between the overlapping edges of the sheet during construction, and between the sheet and the engineering base layer, and can generate a base-layer bonding effect with the same life as the main material.
