Abstract

The invention belongs to the technical field of polyester materials used for charging piles, and more specifically relates to a high-temperature-resistant high-moisture-resistant halogen-free flame-retardant polyester composite material, and a preparation method thereof. The high-temperature-resistant high-moisture-resistant halogen-free flame-retardant polyester composite material comprises following raw materials, by weight, 40 to 60 parts of a polyester resin, 2 to 6 parts of a compatibilizer, 0.1 to 0.2 part of an antioxidant, 0.5 to 1.0 part of a hydrolysis inhibitor, 10 to 20 parts of aphosphinate flame retardant, 0.5 to 1.0 part of a flame retardant synergistic agent, 0.5 to 1.5 parts of an ester interchange inhibitor, 0.5 to 1 part of a chain extender, 10 to 30 parts of glass fiber, and 0 .5 to 1.0 part of other additives. Under double 85 test conditions, in 1000h, the high-temperature-resistant high-moisture-resistant halogen-free flame-retardant polyester composite materialpossesses high CTI characteristics, the material mechanical properties are relatively stable, flame resistance is maintained, and no precipitate is generated on the surface of the high-temperature-resistant high-moisture-resistant halogen-free flame-retardant polyester composite material.

Description

technical field

[0001] The invention relates to the technical field of polyester materials for charging piles, in particular to a high-temperature and high-humidity resistant halogen-free flame-retardant polyester composite material and a preparation method thereof. Background technique

[0002] Comparative Tracking Index (CTI for short) is the highest voltage value at which the surface of an insulating material can withstand 50 drops of electrolyte (0.1wt% ammonium chloride aqueous solution) without forming leakage traces, and the unit is V. That is to say, CTI is the highest voltage value at which 50 drops of conductive liquid are dripped on the surface of insulating plastic without carbonization short circuit under the condition of electrification. Generally speaking, the higher the CTI value of the insulating plastic, the better its leakage resistance.

[0003] With the improvement of people's living standards and the continuous pursuit of convenient transportation, the...
