The present invention uses the chlorinated polyethylene elastomer whose chlorine content is 35+5% as the basic material, and adds a large amount of main filling agent: natural wollastonite powder, and then adds the accessory filling agents, white granular filling agent, plasticizer, stabilizing agent, etc., and further the above-mentioned materials are processed and formed in the conventional equipment. As the amount of addition of the wollastonite is up to 210-380 Phr, the tensile strength of the sheets made by use of the invented method is greater than or equal to 7.5 MPa, its extensibility is greater than or equal to 300%, right-angle tearing strength is greater than or equal to 30 N/mm, after hot-air aging at 80 de.c for 168h, its performance-maintained rate is greater than or equal to 80%. Those sheets are applicable to roof water-proofing and liners of water-storage system. |
