Beschreibung
Zusammenfassung:	The invention discloses an EVA (Ethylene-Vinyl Acetate copolymer) water stop and a preparation method therefor. The EVA water stop is prepared from the raw materials in parts by mass: 100 parts of EVA, 10-15 parts of ethylene propylene terpolymer rubber, 40-80 parts of composite reinforcer, 1-8 parts of vulcanizing agent and 1-3 parts of vulcanizing accelerator. The EVA water stop is prepared through the processes of blending, vulcanizing, shaping and the like. The EVA water stop has the characteristics of high tensile strength, aging resistance, corrosion resistance and the like and is applicable to projects such as infrastructure projects, underground facilities, tunnels, sewage treatment plants, water conservation and subways.
