Abstract

The invention discloses an aluminum foil reinforced TPO butyl rubber self-adhesive waterproof coiled material with a backing. The invention relates to the field of self-adhesive polymer waterproof coiled materials, and aims to provides the aluminum foil reinforced TPO butyl rubber self-adhesive waterproof coiled material with the backing. According to the aluminum foil reinforced TPO butyl rubberself-adhesive waterproof coiled material with the backing, high-elasticity polyester fibers are compounded on a TPO base material, the fibers can be well bonded with mortar and other conventional bonding materials, the construction efficiency is greatly improved, and resource waste is reduced; the aluminum foil reinforced TPO butyl rubber self-adhesive waterproof coiled material with the backing sequentially comprises an isolation layer, a self-adhesive layer, a base material and the backing from top to bottom, and the backing is made of high-elasticity polyester fibers. The invention furtherprovides a preparation method of the aluminum foil reinforced TPO butyl rubber self-adhesive waterproof coiled material with the backing.

Description

technical field [0001] The invention relates to the field of self-adhesive polymer waterproof coiled material, in particular to an aluminum foil reinforced TPO butyl adhesive self-adhesive waterproof coiled material with a backing and a preparation method thereof. Background technique [0002] In recent years, the polymer waterproof membrane represented by TPO self-adhesive waterproof membrane has many advantages such as no pollution, long life, recyclability, reflection and energy saving, good flexibility, excellent welding performance, etc., and its momentum has developed rapidly. More and more people are willing to use TPO self-adhesive waterproof membrane. The polymer self-adhesive TPO waterproofing membrane not only has strong constructability, but also can be permanently bonded with the concrete structure layer, and there is no hidden danger of water channeling in the middle, forming a perfect waterproof system, which greatly improves the reliability of the waterproof ...
