Dynamic-vulcanization thermoplastic polyolefine waterproof roll material and preparation method thereof

Abstract

The invention provides a dynamic-vulcanization thermoplastic polyolefine waterproof roll material and a preparation method thereof. The roll material is characterized by comprising a main body layer and a reinforcing layer arranged according to the need. The main body layer is made of a dynamic-vulcanization thermoplastic polyolefine elastomer. The reinforcing layer comprises a middle reinforcing layer and a surface back-lining layer arranged according to the need. The dynamic-vulcanization thermoplastic polyolefine waterproof roll material has good processing property and excellent mechanical property and has the advantages of great tensile strength, good size stability, strong perforation resistance capability, good ultraviolet resistance and small specific gravity, main body welding seaming realized during the construction, convenient construction, recyclability of corner leftover material, and the like.

Description

1. Technical field: [0001] The invention relates to the field of building materials, in particular to a dynamically vulcanized thermoplastic polyolefin waterproof coiled material and a preparation method thereof. 2. Background technology: [0002] With the popularization and development of modern building technology and new building material technology, the demand for waterproof materials in the field of construction engineering is increasing, and the quality requirements are also getting higher and higher, thus providing a broad scope for the promotion and application of new polymer coils At present, the relatively mature polymer membranes in China mainly include EPDM vulcanized membranes and polyvinyl chloride (PVC) waterproof membranes. However, EPDM vulcanized coils are non-polar and difficult-to-stick materials, so its bonding problem has always been a problem for the popularization and application of this material. This year, the country has developed a matching butyl ...

AI Technical Summary

Problems solved by technology

However, EPDM vulcanized coils are non-polar and difficult-to-bond materials, so its bonding problem has been hindering the popularization and application of this material. This year, the country has developed a matching butyl rubber adhesive. The belt solves the above problems, but the relatively high price of butyl rubber adhesive tape still affects the application and development of EPDM vulcanized membranes; the relative price of polyvinyl chloride (PVC) waterproof membranes is relatively low , can be welded on the body, and there is no bonding problem, but polyvinyl chloride (PVC) waterproof membranes also have fatal flaws, that is, plasticizers are easy to migrate and leak technically, which eventually leads to limited popularization and application
