Abstract

The invention discloses a flame-retardant glass fiber-reinforced HDPE / PA1010 alloy material with a high CTI value and a high GWIT value. The alloy material comprises the following components: by weight, 23 to 41% of HDPE, 22 to 41% of PA1010, 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 compatilizer, 0.1 to 1% of an anti-oxidant and 0.1 to 1% of an oxide. A preparation method for the alloy 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 200 to 220 DEG C and screw revolution is 30 to 40 Hz. The alloy 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 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 a HDPE / PA1010 alloy material, in particular to a flame-retardant glass fiber reinforced HDPE / PA1010 alloy material with high CTI value and high GWIT value. Background technique [0002] Nylon (Nylon), Chinese name polyamide, English name Polyamide (referred to as PA), is a general term for thermoplastic resins containing repeated amide groups -[NHC0]- on the main molecular chain. Its name depends on the specific number of carbon atoms in the synthetic monomer, such as: nylon-6, 66, 1010, 610. It has high crystallinity and obvious melting point; high surface hardness, wear resistance, small friction coefficient, self-lubrication and noise reduction. It has good low temperature performance and certain heat resistance (it can be used below 100 degrees). Non-toxic, odorless, non-mildew, self-extinguishing, good weather resistance, but poor dyeing. High Density Polyethylene (HDPE for short) is a non-polar thermoplastic resin with...
