Abstract

The invention belongs to the technical field of high molecular materials, and relates to a PET material for energy-saving lamp holder and a preparation method of the PET material. The material comprises the following components in parts by weight: 60-80 parts of PET, 10-30 parts of glass fiber, 0.3-0.6 parts of a lubricating agent, 0.3-0.6 part of an antioxidant, 0.2-0.7 part of a nucleating agent and 10-12 parts of a fire retardant. The material disclosed by the invention has the characteristics of high strength, good flame retardant property, high temperature resistance, easy forming and the like, is suitable for manufacturing of energy-saving lamp holder, and is widely applicable in the market due to the lower cost.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a PET material for an energy-saving lamp lamp holder and a preparation method thereof. Background technique [0002] Polyethylene terephthalate (PET) is an engineering plastic with excellent comprehensive properties. PET has excellent mechanical properties, high rigidity, high hardness, good toughness, impact resistance, friction resistance and creep resistance. Good chemical resistance, soluble in cresol, concentrated sulfuric acid, nitrobenzene, trichloroacetic acid, chlorophenol, insoluble in methanol, ethanol, acetone, alkanes, etc. It itself is mainly blown into various bottles, used as containers, and spun into fibers. As an engineering plastic, it can replace nylon and polybutylene terephthalate in the electronic appliances and automobile industries. [0003] The lamp holders of energy-saving lamps on the market are mainly made of aluminum alloy, nylon, and PBT,...
