Abstract

The invention discloses a halogen-free flame-retardant and cold-resistant PC material suitable for a charging pile charging gun and a preparation method thereof. The material comprises the following components in percentage by weight: 92-94 percent of polycarbonate polydimethylsiloxane, 0.1-0.12 percent of a flame retardant, 4-6 parts of a toughening agent, 0.5-0.6 percent of an anti-dripping agent, 0.1-0.2 percent of a main antioxidant, 0.3-0.4 percent of an auxiliary antioxidant, 0.4-0.5 percent of a lubricating agent and 0.3-0.5 percent of a weather resistance agent. A polycarbonate polydimethylsiloxane block copolymer is excellent in low temperature resistance as a dimethylsiloxane segment is introduced; meanwhile, polydimethylsiloxane can promote PC carbon forming during combustion, has a good synergistic flame-retardant effect together with an additive type flame retardant agent and can effectively reduce the consumption of the additive type flame retardant agent. The halogen-free flame-retardant and cold-resistant PC material suitable for the charging pile charging gun is prepared by taking the polycarbonate polydimethylsiloxane as a main body and through the addition of the sulfonate flame retardant, the organic silicon type toughening agent, the anti-dripping agent, the antioxidant, the weather resistance agent, the lubricating agent and the melt blending of a double-screw extruder.

Description

Technical field [0001] The invention belongs to the field of polymer functional composite materials, and specifically relates to a halogen-free flame-retardant and cold-resistant PC material suitable for charging pile charging guns and a preparation method thereof. Background technique [0002] Electric vehicles have the characteristics of zero emissions, high energy efficiency, low noise, etc., and are strongly supported by national policies and are developing rapidly. However, the current electric vehicle charging infrastructure is not perfect, which limits the popularization of rechargeable vehicles. As a crucial part of the charging infrastructure for electric vehicles, charging guns have almost strict requirements on the materials used due to the particularity and difference of their use environment: good mechanical properties make them resistant to falling and rolling; excellent Low temperature resistance to meet the requirements of use under different climatic conditions;...
