AI Technical Summary

Problems solved by technology

ABS resin has high mechanical strength and good processability, but its flame retardancy is poor. Therefore, most ABS resins used in lead-acid battery shells have been modified by flame retardancy, and their strength is generally difficult to meet the requirements after modification. Reinforcement and toughening modifications are also required
ABS resin used alone has poor flame retardancy and strength. Although PC used alone has high mechanical strength and impact resistance, it has high cost and poor processability, and is prone to internal stress.

Description

technical field [0001] The invention relates to a lead-acid storage battery casing. Background technique [0002] Most of the shell materials of lead-acid batteries are ABS, and PP is used in automobiles. [0003] Lead-acid battery is a chemical power source with large output and wide application, which is widely used in various fields such as communication, automobile, and energy storage. Since the shell of the lead-acid battery requires acid and alkali resistance, high strength and good processability, the lead-acid battery for communication usually uses ABS resin as the basic raw material. ABS resin has high mechanical strength and good processability, but its flame retardancy is poor. Therefore, most ABS resins used in lead-acid battery shells have been modified by flame retardancy, and their strength is generally difficult to meet the requirements after modification. Reinforcing and toughening modifications are also required. ABS resin used alone has poor flame retar...
