Abstract

The invention relates to a PVC (polyvinyl chloride) combination for a storage battery shell and a preparation method thereof, belongs to the field of material science and in particular relates to an injection molding heat-resisting PVC combination and a preparation method thereof, wherein the combination is applicable to producing the storage battery shell. By virtue of adopting PVC resins with low polymerization degree, and combining specific compound heat-resisting modifiers, size stabilizers and full-ester impact modifiers, the PVC combination which has higher vicat softening temperature and superior impact property is produced. Compared with the prior art, the PVC has the following advantages: by virtue of adopting the heat-resisting modifiers with specific components and combining the size stabilizers, the heat-resisting performance of the PVC resins is improved, and therefore the PVC combination for the storage battery shell provided by the invention has higher vicat softening temperature, and by virtue of adopting the full-ester impact modifiers, the material has superior impact property, and meanwhile the anti-photoaging performance is prevented from being reduced.

Description

technical field [0001] The invention discloses a polyvinyl chloride composition for battery casings and a preparation method thereof, belonging to the field of material science, and relates to an injection-molded heat-resistant polyvinyl chloride composition and a preparation method thereof, and the composition is suitable for producing battery casings. Background technique [0002] With the rapid development of the automobile and electric vehicle industry, the battery consumption is increasing. The service conditions of the battery require that the outer casing of the material must have a high heat distortion temperature, flame retardancy and light and heat aging resistance. At present, the main materials of the battery casing are polypropylene and ABS resin. Due to the poor flame retardancy of polypropylene and ABS resin, flame retardant modification must be carried out during use. Polyvinyl chloride resin itself has flame retardant properties, but its heat distortion tem...
