Abstract

The invention discloses a flame-retardant glass fiber-reinforced HIPS / PPO material with a high CTI value and a high GWIT value. The alloy material comprises the following components by weight: 23 to 41% of HIPS, 22 to 41% of PPO, 6 to 15% of a compound fire retardant, 3 to 10% of antimonony oxide, 20 to 30% of a glass fiber, 2 to 9% of a toughening agent, 0.1 to 1% of an anti-oxidant and 0.1 to 1% of an oxide. A preparation method for the material comprises the following steps: weighing the components in proportion, adding the weighed components into a high-speed mixer for mixing for 2 to 5 min, then carrying out discharging and finally carrying out extrusion granulation in a twin-screw extruder, wherein processing temperature is 220 to 240 DEG C and screw revolution is 30 to 40 Hz. The material provided by the invention has the advantages of a high CTI value, a high GWIT value, environment-friendliness and balanced comprehensive properties and can be used for low-voltage electronic capacitor shells, load break switches, carbon brush supports and molded case circuit breakers.

Description

technical field [0001] The invention relates to a HIPS / PPO alloy material, in particular to a flame-retardant glass fiber reinforced HIPS / PPO alloy material with high CTI value and high GWIT value. Background technique [0002] PPO is one of the five general-purpose engineering plastics in the world. It has the advantages of high rigidity, high heat resistance, flame retardant, high strength and excellent electrical properties. In addition, polyphenylene ether also has the advantages of wear resistance, non-toxicity, and pollution resistance. The dielectric constant and dielectric loss of PPO are one of the smallest varieties among engineering plastics, and they are hardly affected by temperature and humidity, and can be used in low, medium and high frequency fields. The load deflection temperature of PPO can reach above 190°C, and the embrittlement temperature is -170°C. As one of the world's five general-purpose engineering plastics, PPO material is non-toxic and has lo...
