Abstract

The invention discloses a high-toughness and high-rigidity ABS composite material special for a storage battery shell, a preparation method and application thereof. The composite material comprises the following components by weight: 10-20 parts of ABS resin; 10-25 parts of ABS high rubber powder; 40-55 parts of styrene-acrylonitrile resin; 4-8 parts of wollastonite; 16-25 parts of a flame retardant; and 0.3-1 part of an antioxidant; wherein the wollastonite is fibrous wollastonite. The ABS composite material disclosed by the invention has high rigidity and high toughness, the flexural modulusis greater than 2300MPa, the toughness is greater than 21kJ/m<2>, and the ABS composite material can be applied to a storage battery shell.

Description

technical field [0001] The invention relates to the field of engineering plastics, and more specifically relates to a special high-toughness and high-rigidity ABS composite material for battery casings and a preparation method and application thereof. Background technique [0002] A storage battery is a device that directly converts chemical energy into electrical energy and is widely used. Batteries usually have fire protection requirements, so the casings of batteries are usually made of flame-retardant plastics. During transportation, storage, and use, batteries may encounter impacts, drops, etc. Therefore, there are high requirements for the toughness of battery casing materials, and generally need to pass the drop hammer impact test. Another problem that exists in the use of batteries is that due to the long power-on time, vulcanization of the plates, excessive viscosity of the electrolyte, or too little electrolyte, the battery shell bulges and deforms, which affects ...
