Abstract

The invention relates to the field of lead storage battery plastic shells, particularly to an anti-corrosion high-toughness lead storage battery plastic shell, which comprises an organic-inorganic composite plate arranged on the inner side of the plastic shell, and a plastic shell body covering the outer side of the organic-inorganic composite plate, wherein the plastic shell body comprises the following components in parts by weight: 80-100 parts of an ABS resin, 10-25 parts of organic resin toughened glass fiber, 3-10 parts of chlorinated polyethylene, 10-15 parts of a flame retardant, 1-5 parts of a flame retardant synergist, 1-3 parts of a compatilizer and 0.1-0.5 part of a lubricant, and the organic-inorganic composite plate comprises the following components in parts by weight: 100 parts of glass micro-sheet, 35-50 parts of flaky cubic boron nitride, 15-30 parts of an epoxy resin and 0.05-0.1 part of a curing agent. According to the invention, the defect that the mechanical property of the lead storage battery is continuously reduced along with the prolonging of the service time due to the fact that the lead storage battery in the prior art is not corrosion-resistant is overcome, the lead storage battery has good toughness and impact resistance, the corrosion resistance is good, and the use safety of the plastic shell can be ensured for a long time.

Description

technical field [0001] The invention relates to the field of plastic cases for lead storage batteries, in particular to an anti-corrosion plastic case for lead storage batteries with high toughness. Background technique [0002] Lead-acid battery (VRLA) is a battery whose electrodes are mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution. In the discharge state of the lead-acid battery, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the charging state, the main component of the positive and negative electrodes is lead sulfate. [0003] A lead-acid battery is generally composed of five major parts, which are: positive electrode, negative electrode, separator, electrolyte and battery case. The battery casing has the function of protecting the internal components of the battery from being broken by external collisions and electrolyte leakage. However, the materials in th...
