Embodiment Construction
[0028] The high-performance thermoplastic polyolefin waterproof membrane with high waste rubber powder content of the present invention will be further described below in combination with examples and comparative examples.
[0029] The raw material formulas of waste rubber powder-based thermoplastic elastomer implementation cases 1-10 of the present invention are listed in Table 1. Unless otherwise specified, the data in Table 1 are all parts by mass. The waste tire rubber powder with an average particle size of 200 μm was purchased from Jiangyin Anqiang High Wear-resistant Rubber Powder Co., Ltd.; the polypropylene with a yield strength > 24 MPa was selected from Yanshan Petrochemical K8303, Shanghai Petrochemical GM 160E and Maoming Petrochemical EPS30R, with a melt index > 5g / The 10-minute polypropylene uses Shanghai Petrochemical M2101R and Yanshan Petrochemical K9020; SEBS uses Formosa Plastics 6150; phenolic resin chooses HY-2045 from Shanxi Rubber Auxiliary Factory; fo...
