Composite rib material for glass fiber partition plate of storage battery

Abstract

The invention discloses a composite rib material for a glass fiber partition plate of a storage battery. The composite rib material is prepared by mixing and stirring polyvinyl chloride (PVC) paste resin, light calcium carbonate, a foaming agent, a catalyst, a white oil and a plasticizer, wherein the mass ratio of the PVC paste resin, the light calcium carbonate, the foaming agent, the catalyst, the white oil and the plasticizer is (100-150):(20-50):(2,500-3,500):(2,000-3,000):(10-20):(40-70), the catalyst is preferably aluminum stearate, and the plasticizer is preferably dioctyl phthalate. By adding the light calcium carbonate, the hardness of a product after the composite rib material is plasticized for forming a rib is increased; by adding the aluminum stearate as the catalyst, the PVC paste resin can be effectively prevented from degradation in a hot environment, and the stability of the product is ensured; by adding the foaming agent, a large amount of slim holes are generated after roasting the composite rib material, and the porosity of the product is improved; and when the composite rib material is used for the glass fiber partition plate of the storage battery, electrolyte absorption is promoted.

Description

technical field [0001] The invention relates to the production field of accumulator accessories, in particular to a composite rib material used for accumulator glass fiber separators. Background technique [0002] At present, with the development of science and technology, in order to cope with the limitations of petrochemical energy as a non-renewable energy source, the electric vehicle industry using lead-acid batteries as the power source is in a period of vigorous development. Lead-acid battery is a kind of battery with mature technology, safety and environmental protection. During the assembly and production process of lead-acid battery, a separator needs to be sandwiched between the positive and negative plates. As an important part of the battery, the separator needs to It has the following properties: ① The separator of the battery used for starting, ignition and lighting is used as the electrolyte storage, and must be able to absorb enough electrolyte to ensure the ...
