Abstract

The invention discloses lead acid storage battery positive electrode lead paste and a preparation method thereof. The lead acid storage battery positive electrode lead paste is prepared from the following ingredients in parts by weight: 70 to 90 parts of lead powder, 0.01 to 0.1 part of adhesive-free carbon fiber, 0.01 to 0.1 part of basalt fiber, 0 to 0.8 part of 4BS seed crystals, 5 to 12 parts of lead tetraoxide, 2 to 8 parts of antimonous oxide, 1 to 5 parts of polyester fiber, 2 to 6 parts of triniobium aluminum, 2 to 7 parts of sulfuric acid, 6 to 8 parts of hydrosulfate,3 to 6 parts of nanometer silicon dioxide, 15 to 20 parts of nucleocapsid acrylic acid elastic emulsion, 0.5 to 1.5 parts of carboxymethyl cellulose, 0.35 to 1.05 parts of chemical-resistant modifying agents and 9 to 13 parts of pure water. The adhesive-free carbon fiber addition technology is used, and the adhesive-free carbon fiber can enhance the adhesion effect of the lead paste; in addition, the lead paste low-acid content technology is used, so that the battery deep circulation service life is greatly prolonged; through the addition of the nucleocapsid acrylic acid elastic emulsion and the nanometer silicon dioxide, the weathering performance of the lead paste is improved; the perfluoroalkyl acrylic acid series additives are introduced to be used as chemical-resistant modifying agents, so that the anti-corrosion performance of the lead paste is greatly improved.

Description

technical field [0001] The invention relates to the field of storage batteries, in particular to a lead-acid storage battery cathode lead paste and a preparation method thereof. Background technique [0002] With the attention of various countries on climate change and the gradual improvement of people's awareness of environmental protection, the voice of reducing vehicle exhaust emissions is also getting higher and higher. Pollutants emitted by motor vehicles mainly include hydrocarbons (HC), nitrogen oxides (NOx), carbon monoxide (CO), particulates (PM) and other harmful substances, which will have a direct impact on global climate change, environmental pollution, and human health. Reducing vehicle exhaust emissions has basically become the common understanding of the world's major economies. [0003] The micro-hybrid idling start-stop car has obvious practical significance in terms of saving fuel, reducing greenhouse gas, and toxic and harmful gas emissions. According t...
