Abstract

The invention discloses a flame-retardant glass fiber-reinforced ABS / PA66 alloy material with a high CTI value and a high GWIT value. The alloy material comprises the following components: by weight, 22.5 to 41% of ABS, 22.5 to 41% of PA66, 6 to 20% of a compound fire retardant, 3 to 15% of antimonony oxide, 20 to 30% of a glass fiber, 2 to 10% of a compatilizer, 0.1 to 1% of an anti-oxidant and 0.1 to 1% of a metallic oxide. In preparation of the alloy material, all the components are added into a high-speed mixer for mixing for 2 to 5 min, and then discharging and extrusion granulation are carried out, wherein extrusion temperature is 220 to 255 DEG C and screw revolution is 30 to 40 Hz. Compared with the prior art, the alloy material provided by the invention has the advantages of a high glow wire temperature, a high tracking index, environment-friendliness, balanced comprehensive properties and the like and can be extensively 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 an ABS / PA66 alloy material, in particular to a flame-retardant glass fiber reinforced ABS / PA66 alloy material with high CTI value and high GWIT value. Background technique [0002] ABS resin features: the resin has good comprehensive properties, high impact strength, chemical stability, and good electrical properties; it has good fusion properties with plexiglass, and can be made into two-color plastic parts, and the surface can be chrome-plated and spray-painted; it has high impact resistance. , high heat resistance, flame retardant, enhanced, transparent and other grades; fluidity is a little worse than HIPS, better than PMMA, PC, etc., and good flexibility; Nylon (Nylon), Chinese name polyamide, English name Polyamide (referred to as PA), It is a general term for thermoplastic resins containing repeating amide groups—[NHCO]—on the main molecular chain. Its name depends on the specific number of carbon atoms in the synthetic...
