Problems solved by technology

[0003] In the prior art, ABS resin is often used as a raw material for the lead-acid battery plastic case, and the lead-acid battery plastic case is made by injection molding, but the weather resistance and chemical stability of the ABS resin are poor, and its mechanical properties are also poor. After a period of use, there is usually a sharp decline in performance, deterioration of mechanical properties, hard and brittle materials, etc. It is difficult to meet the relevant requirements of current lead-acid battery manufacturing.

Abstract

The invention belongs to the technical field of lead-acid storage batteries, and discloses a high-strength plastic case of a lead-acid storage battery. The plastic case is prepared from ABS resin, PVCresin, nitrile butadiene rubber, reinforcing fibers, modified mica, modified white carbon black, an antioxidant, an antiager, stearic acid, a solvent and the like through injection molding. The reinforcing fibers are zirconium titanate fibers subjected to surface modification. The plastic case has high mechanical strength and impact strength, good toughness, high tensile strength and flexural modulus, good thermal stability, and good resistance to high voltages.

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a high-strength molded case of lead-acid batteries. Background technique [0002] After more than 100 years of development, the related technologies of lead-acid batteries have become mature and the cost is relatively low. They are widely used in many economic fields such as transportation, communication, electric power, military, and navigation, and become an indispensable chemical power source. As an important part of the lead-acid battery, the plastic case of the lead-acid battery plays the role of carrying the important parts of the battery such as the plate, the separator and the electrolyte. It is required to have good chemical corrosion resistance, high stability, high Strength and good machinability. [0003] In the prior art, ABS resin is often used as a raw material for the lead-acid battery plastic case, and the lead-acid battery plastic case is made by in...
