Embodiment 1

[0027] Embodiment 1: A special ABS material for battery casing, each component and mass fraction in the raw material are as shown in Table 1, wherein, the content of acrylonitrile in the styrene-acrylonitrile resin is 5% of the content of the styrene-acrylonitrile resin 25%-35%, the melt index of styrene-acrylonitrile resin under the test condition of 200℃×5kg is 2.5g / 10min, the brominated flame retardant is brominated epoxy resin, and the antimony-based flame retardant is trioxide Diantimony, the toughening agent is powdered nitrile rubber, and the antioxidant is tetrakis [β-(3,5 di-tert-butyl-4-hydroxyphenyl) propionate] pentaerythritol ester.

[0028] The manufacturing process of the ABS material specially used for battery shells, according to the proportions of the components in Table 1, weighed the components of the formula amount, added them to the high-speed mixer and mixed them evenly, then sent them into the twin-screw extruder, and the twin-screw extruder The tempera...

Embodiment 2

[0029] Example 2: A special ABS material for battery casings. The difference from Example 1 is that the components and mass fractions in the raw materials are shown in Table 1. Among them, the ABS high rubber powder has a rubber content of 50-65%, the antimony-based flame retardant is antimony pentoxide, and the antioxidant is β-(-4-hydroxy-3,5-di-tert-butylphenyl)propionic acid n- Octadecyl ester, the processing aid is ethylene bis stearamide.

Embodiment 3

[0030] Embodiment 3: A special ABS material for battery casings. The difference from Embodiment 1 is that the components and mass fractions in the raw materials are shown in Table 1. Wherein, the antimony-based flame retardant is sodium antimonate, the antioxidant is tris(2,4-di-tert-butylphenyl) phosphite, and the processing aid is magnesium stearate.

Abstract

The invention discloses a special ABS material for a storage battery case. The material comprises the following ingredients by mass percentage: 20-35% of ABS high glue powder, 35-60% of styrene-acrylonitrile resin, 5-20% of a brominated flame retardant, 3-6% of an antimonic flame retardant, 2-6% of a flexibilizer and 0.2-1% of an antioxidant. The material has the following advantages and effects that: the styrene-acrylonitrile resin and the ABS high glue powder serve as the major raw materials; the flame resistance is significantly improved by adding the brominated flame retardant and the antimonic flame retardant; the corrosion resistance and heat resistance of the special ABS material for the storage battery case are improved by adding the antioxidant; when the special ABS material for the storage battery case is prepared into a storage battery, the material can meet operating requirements of the storage battery; a service life of the storage battery is prolonged.

Description

technical field [0001] The invention relates to the field of molding materials, in particular to an ABS material specially used for battery shells. Background technique [0002] A storage battery is a device that directly converts chemical energy into electrical energy. It is designed to be rechargeable and rechargeable through a reversible chemical reaction. It belongs to a secondary battery. The shell of the battery is filled with electrolyte and polar plates, and the battery will continue to generate heat during charging and discharging, so the shell of the battery needs to have high heat resistance and flame retardancy. Secondly, the drop and impact of the battery during use may damage the battery casing, so the battery casing also needs to have better impact resistance. [0003] Early storage batteries were mainly made of hard rubber, which was hard and brittle with poor impact resistance. ABS material is a polymer material with high strength, good toughness and easy ...
