Abstract

The invention discloses modified polycarbonate plastic for packaging. The modified polycarbonate plastic comprises the following components in percentage by weight: 65-75 percent of polycarbonate, 10-20 percent of polystyrene, 5-10 percent of nanometer titania, 3.5-6.5 percent of nano silica, 3-6 percent of a silane coupling agent, 3.5-5.5 percent of carbon black, 1.5-4.5 percent of an antioxidant, 2.5-4.5 percent of a lubricating agent and 1.5-3.5 percent of a flame retardant. According to the mode, the modified polycarbonate plastic for packaging disclosed by the invention has high impact resistance, high transparency and high ultraviolet resistance and can be applied to automotive glass or LED and other packaging materials with high transparency requirements.

Description

technical field [0001] The invention relates to modified plastics, in particular to a modified polycarbonate plastic for packaging. Background technique [0002] Polycarbonate has excellent physical and mechanical properties, excellent impact resistance, high tensile strength, bending strength and compression resistance; small creep, stable size, colorless and transparent, good heat resistance and low temperature resistance. However, polycarbonate is prone to stress cracking, and has poor weather resistance and wear resistance. In order to take advantage of the advantages of polycarbonate during use, various modified polycarbonates have also appeared on the market. [0003] With the development of science and technology, especially the rapid development of automobiles or LEDs, the packaging requirements for automotive glass or LEDs are becoming more and more stringent. The existing packaging materials have low transparency, heat resistance and wear resistance. It meets its...
