Composition for preparing Ethylene Vinyl Acetate Copolymer, Ethylene Vinyl Acetate Copolymer, and Method of manufacturing thereof

摘要

The invention discloses a composition used for preparing an EVA copolymer cross-linked in trace amount, the EVA copolymer and a preparation method of the EVA copolymer. The composition comprises gel or fisheye which is provided with high fusion tension and lowest probability. The composition comprises 50-500 pm one kind or various kinds of organic peroxides which are selected from dialkyl peroxides crosslinking agent, alkyl group peroxy esters crosslinking agent and peroxy ketals crosslinking agent and have one-minute half-life period temperature of 130 DEG to 190 DEG C. the composition also comprises 50-250 ppm common crosslinking agent, 100-1500 pm diluents and 50-600 ppm antioxidant and ethylene-vinyl acetate (EVA) with melt index (MI) of 8-25g/10min and with 26%-28wt% of vinyl acetate (VA).
