Abstract

The invention belongs to the technical field of lead storage battery materials and provides a halogen-free shell body material for a lead storage battery and a preparation method. The halogen-free shell body material for the lead storage battery is prepared from the following raw materials in parts by weight: 60 to 80 parts of ABS (Acrylonitrile Butadiene Styrene), 20 to 25 parts of polypropylene, 0.5 to 5 parts of a halogen-free flame retardant, 0.8 to 2.0 parts of an antioxidant, 1.7 to 2.5 parts of a dispersant, 3 to 6 parts of a toughening agent and 1 to 3 parts of a lubricant. The halogen-free shell body material for the lead storage battery has relatively good strength, good impact resistance, ageing resistance and acid resistance and good flame-retarding performance and is suitable for a lead acid battery shell body to use.

Description

technical field [0001] The invention belongs to the technical field of lead storage battery materials, and in particular relates to a halogen-free casing material for lead storage batteries and a preparation method thereof. Background technique [0002] Existing lead-acid battery casing materials are usually produced by common ABS materials, which are relatively good in strength, impact resistance, and aging resistance. However, due to the poor fire resistance of this material, it is easy to burn. Therefore, flame retardant requirements are put forward for the lead battery shell material. The flame retardant technology is to meet the needs of social safety in production and life, prevent fires, and protect people's lives and property. A science developed. In recent years, it has attracted the attention of all walks of life. [0003] At present, for ABS flame retardant materials, most of them are non-environmentally friendly flame retardant materials, that is, brominated fl...
