Abstract

The invention relates to the technical field of lead-acid storage batteries, and provides a lead-acid battery flame-retardant plastic shell and a preparation method thereof, which solve the problems that the heat resistance and thermal stability of the existing lead-acid battery plastic shell are poor, the lead-acid battery plastic shell is easily decomposed at high temperature to generate discoloration, the performance is degraded, the hydrogen chloride toxic gas is released, and the flame retarding performance is limited. The preparation raw materials comprise 100 parts by weight of ABS resin, 40 to 60 parts by weight of PVC resin, 15 to 30 parts by weight of nitrile rubber, 10 to 14 parts by weight of a flame retardant filler, 6 to 10 parts by weight of biomass powder, 15 to 25 parts byweight of a flame retardant modification agent, 3 to 5 parts by weight of an antioxidant, 2 to 3 parts by weight of an anti-aging agent, and 8 to 11 parts by weight of stearic acid. The plastic shellhas the advantages of high flame retardancy, low specific gravity, and high strength and toughness.

Description

Technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a flame-retardant plastic case of lead-acid batteries and a preparation method thereof. Background technique [0002] After more than 100 years of development, lead-acid batteries have matured and the cost is relatively low. Lead-acid batteries have been widely used in many economic fields such as transportation, communications, electric power, military, and navigation, and have become an indispensable chemical power source. As an important component of lead-acid battery, plastic case of lead-acid battery plays a role of supporting important battery components such as plate, separator and electrolyte. It is required to have good chemical corrosion resistance, high stability and high Strength and good machining performance. [0003] In the prior art, the plastic case of lead-acid battery often uses ABS resin and PVC resin as the main raw materials. The plastic case of lead-a...
