Problems solved by technology

Organic infrared shielding additives derived from polycyclic aromatic amines and salts, such as N,N,N',N'-tetrakis(p-di-n-butylaminophenyl)-p-phenylenediamine and N,N,N ',N'-Tetrakis(p-di-n-butylaminophenyl)-p-benzoquinone-di-(hexafluoroammonium antimonate) can provide infrared absorption; however, these compounds generally lack the ability to withstand extrusion and Thermal and oxidative stability required for molding conditions without decomposition

Abstract

A composition is disclosed, comprising a polycarbonate resin, an inorganic infrared shielding additive, and carbon black, wherein an article prepared from the composition has the inorganic infrared shielding additive present at about 0.01 to about 1.0 grams per square meter, and carbon black present at about 0.001 to about 2.0 grams per square meter. The article prepared from the composition meets at least one scale requirement for European Norm EN 169 and / or EN 171, and is useful for preparing infrared shielding protective eyewear with low haze.

Description

Background technique [0001] The invention relates to a polycarbonate composition, in particular to a polycarbonate composition with infrared (IR) absorption, a preparation method and application thereof. [0002] Polycarbonate can be used in applications where good impact strength, low haze, and high transparency are desired. Protective goggles are in such applications where polycarbonate is suitable, including protective goggles designed to limit the exposure of the eyes to potentially harmful radiation. Included in this category are protective glasses for applications where moderate to high intensity infrared radiation is present, such as welding, casting work, blown glass, and other similar types of thermal processing. As a guideline for the performance of materials and products for infrared radiation protection glasses that block a certain amount of radiation, standards such as European Norm EN 166, EN 169, and EN 171 have been proposed. Both EN 169 and EN 171 include differen...
