Abstract

The invention discloses an aging-resistant easy-welding thermoplastic polyolefin waterproof roll material and a preparation method thereof. The aging-resistant easy-welding thermoplastic polyolefin waterproof roll material consists of the following raw materials in parts by mass: 40-60 parts of polyolefin elastomer, 20-40 parts of polypropylene, 10-30 parts of filling masterbatch, 0.2-0.5 part ofantioxidant, 0.2-0.6 part of light stabilizer, and 1-4 parts of titanium dioxide. The aging-resistant easy-welding thermoplastic polyolefin waterproof roll material is prepared through a two-step method, and the preparation method comprises a first step of raw material extrusion granulation and a second step of particle press polish molding. The prepared thermoplastic polyolefin waterproofing rollmaterial has excellent aging resistance and long-term weather resistance, has good high and low temperature performance, is easy welding, has good waterproof performance, is not easy to crack, is green and environmentally friendly, has good construction performance, and can be applied to areas with larger environment temperature changes.

Description

technical field [0001] The invention relates to an aging-resistant and easy-to-weld thermoplastic polyolefin waterproof coiled material and a preparation method thereof. Background technique [0002] With the popularization and development of various modern buildings and related technologies, the demand for waterproof materials in the field of construction engineering is increasing, and the quality requirements for them are also getting higher and higher. With the introduction of single-ply roofing systems in Europe and the United States and rapid development at home and abroad, its supporting waterproof membranes are also developing continuously, and have gradually become the mainstream of waterproof membrane development. As a new type of waterproof membrane, thermoplastic polyolefin waterproof membrane is mainly composed of hydrocarbons and does not contain other chemical elements. It has the weather resistance of EPDM waterproof membrane and the performance of PVC waterpr...
