Composition and process for preparing nir shielding masterbatch and nir shielding masterbatch and application thereof

摘要

Disclosed herein is a method for preparing a near infrared shielding masterbatch. The method includes the steps of preparing and compounding a composition, and then pelletizing the compounded composition. The composition includes at least one metallic ionic compound powder in an amount of about 1-25 wt%, a cross-linking agent in an amount of about 0.1-5 wt%, a thermoplastic polymer in an amount of about 67-98.7 wt%, an initiator in an amount of about 0.1-1 wt%, and a dispersing agent in an amount of about 0.1-2 wt%.
