Resin material, method for producing the same, and use thereof

Abstract

This invention relates to the field of resin technology for bottle caps, and discloses a resin material, its preparation method, and its application. The resin material contains ethylene-butene copolymer resin, a halogen absorbent, a fluoropolymer, and an adsorbent, wherein the density of the ethylene-butene copolymer resin is 0.948-0.962 g / cm³. 3 The melt flow index is 1-8 g / 10 min at 190℃ and 2.16 kg load, and the proportion of oligomers with a molecular weight below 1000 is less than 0.8 wt%. The adsorbent is at least one of type 3A molecular sieve, type 4A molecular sieve, type 13X molecular sieve, type ZSM-5 molecular sieve, and ZIF series metal-organic framework compounds. According to the technical solution of the present invention, by effectively controlling the content, type, and proportion of ethylene-butene copolymer resin, halogen absorbent, fluoropolymer, and adsorbent in the resin material, the resin material can possess both excellent processing performance and physical and mechanical properties while meeting the low-odor food hygiene requirements.
