Title:
HIGH-SLIP-RESISTANCE PRE-PAVED WATERPROOF COILED MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/222283
Kind Code:
A1
Abstract:
The present invention relates to a high-slip-resistance pre-paved waterproof coiled material and a preparation method therefor. The pre-paved waterproof coiled material comprises a base material layer, an adhesive layer and an anti-sticking layer, which are sequentially laminated; the base material layer comprises an upper layer and a lower layer; the upper layer and the lower layer are prepared by co-extrusion of a first material and a second material; the raw material formula of the first material comprises matrix resin and polyolefin elastomer; and the raw material formula of the second material comprises polyolefin elastomer. According to the present invention, by configuring the base material layer as a structure having the upper layer and the lower layer, preparing the upper layer and the lower layer by means of co-extrusion, and preparing the lower layer by using the polyolefin elastomer as a main raw material, the pre-paved waterproof coiled material not only has a high static friction coefficient, achieves an excellent anti-slip effect, is convenient to construct, but same also has excellent mechanical properties, there is a larger bonding force with a lap joint. In addition, the upper layer and the lower layer of the base material layer are prepared by means of co-extrusion, and the processing technology of the pre-paved waterproof coiled material is simple.
