Abstract

The invention discloses a polyolefin elastomer waterproof roll and a preparation method thereof. The polyolefin elastomer waterproof roll comprises the following components: polyolefin resin and a supported auxiliary agent, wherein the polyolefin resin comprises rubber, polypropylene, a polyolefin elastomer, an initiator and an assistant cross-linking agent; the supported auxiliary agent comprises a carrier and an auxiliary agent, and the auxiliary agent comprises at least one of an antioxidant, an anti-ultraviolet agent, a flame retardant and a pigment. The polyolefin elastomer waterproof roll provided by the invention is stable in performance, has excellent aging resistance, weather resistance, cracking resistance and weldability, is particularly suitable for waterproofing of various roofs, and has a wide market prospect.

Description

technical field [0001] The invention relates to the technical field of building waterproofing, in particular to a polyolefin elastomer waterproofing coiled material and a preparation method thereof. Background technique [0002] In recent years, the third-generation single-layer roof waterproofing system represented by polyolefin elastomer waterproofing membranes has begun to appear. It combines the advantages of EPDM waterproofing membranes and PVC waterproofing membranes, and can effectively solve various problems. The engineering leakage problem of a kind of use environment. [0003] However, at present, the production technology and product quality of such waterproof membranes in my country are still relatively backward, and there are still certain gaps in the aging resistance, weather resistance, crack resistance and weldability of polyolefin elastomer waterproof membranes compared with foreign countries, which seriously affects Promotional use of products. The present...
