Abstract

The invention relates to a high anti-slip pre-paved waterproof coiled material and a preparation method thereof.The pre-paved waterproof coiled material comprises a base material layer, an adhesive layer and an anti-sticking layer which are sequentially arranged in a stacked mode, the base material layer comprises an upper layer and a lower layer, and the upper layer and the lower layer are prepared by co-extrusion molding of a first material and a second material; the raw material formula of the first material comprises matrix resin and a polyolefin elastomer; the raw material formula of the second material comprises a polyolefin elastomer. The base material layer is arranged to be of a two-layer structure including the upper layer and the lower layer; the upper layer and the lower layer are prepared through co-extrusion, and the lower layer is prepared by taking the polyolefin elastomer as a main raw material, so the pre-laid waterproof roll has a high static friction coefficient, an excellent anti-sliding effect is provided for the pre-laid waterproof roll, and construction is convenient and fast; and the adhesive also has excellent mechanical properties and relatively large bonding force with a lap joint edge. The upper layer and the lower layer of the base material layer are prepared through co-extrusion, and the processing technology of the pre-laid waterproof roll is simple.

Description

technical field [0001] The invention belongs to the technical field of waterproof building materials, and in particular relates to a high-slip-resistant pre-paved waterproof coiled material and a preparation method thereof. Background technique [0002] The currently known polymer pre-laid waterproof membrane usually uses a polymer sheet as a carrier, a hot-melt pressure-sensitive adhesive as an adhesive layer, and sand and gravel as an anti-sticking layer on the surface. These products are overlapped with each other to form a reliable waterproof effect. They are constructed in the form of pre-paved and anti-adhesive, and are widely used in engineering fields such as basements, underground pipe galleries, subways or tunnels. [0003] However, at present, the sheet carrier of polymer pre-paved waterproofing membrane is usually mainly modified high-density polyethylene, which directly contacts the cement floor during construction. Due to the high crystallinity of polymer polye...
