Problems solved by technology

However, after injection molding of polycarbonate, the transparent lampshade has a large internal stress. When the lamps using the transparent lampshade are used in high-temperature and high-humidity environments such as offshore platforms, petrochemical plant areas, and oil depots, the transparent lampshade is prone to damage due to internal stress. Cracking due to stress, leading to lamp failure

Abstract

The invention provides a Makrolon composite material. The Makrolon composite material comprises, by weight, 100 parts of Makrolon and 3-5 parts of butyl acrylate-butadiene copolymer. By the adoption of the Makrolon composite material, stress cracking can be prevented. The invention further provides a lamp which uses the Makrolon composite material.

Description

【Technical field】 [0001] The invention relates to a polymer material, in particular to a polycarbonate composite material and a lamp using the polycarbonate composite material. 【Background technique】 [0002] Polycarbonate (PC) is an almost colorless glassy amorphous polymer with good optics, so it is often used to make transparent lampshades for lamps. However, after injection molding of polycarbonate, the transparent lampshade has a large internal stress. When the lamps using the transparent lampshade are used in high-temperature and high-humidity environments such as offshore platforms, petrochemical plant areas, and oil depots, the transparent lampshade is prone to damage due to internal stress. Cracking due to the stress, causing the lamp to fail. 【Content of invention】 [0003] In view of the above situation, it is necessary to provide a polycarbonate composite material capable of preventing stress cracking and a lamp using the polycarbonate composite material.
