Problems solved by technology

Adhesives for lead-acid batteries were mainly produced in Japan and Taiwan. Although the quality is excellent, the price is expensive. Some domestic manufacturers also use epoxy resin and ethylenediamine or T-31 to prepare their own. Although the cost is low, the finished product The pass rate is low, unable to meet the mass production of new lead-acid batteries

Abstract

The present invention relates to a lead accumulator epoxy resins sealant and preparation method thereof, particularly a cementing compound used on lead acid batteries sealing and adhesive bonding. The lead accumulator epoxy resins sealant includes A component and B component, the mass portion proportioning between A component and B component is as following: A:B = 2:1, wherein the raw material mass proportioning of A component is as following: bisphenol A epoxy resins 70-80, bisphenol F epoxy resins 10-15, butyl glycidyl ether 3-5, 2-methylphenol glycidyl ether 8-12, polyurethane 5-8, resin acceptor 0.1; and the raw material mass portion proportioning of B component is as following: aniline 400, polyoxymethylene 70-76, aminic acid 30, water 100-300, benzenemethanol 300-500, anti-oxidant 2, cure accelerator 20-35, and nonyl phenol 60.

Description

technical field [0001] The invention relates to an epoxy resin sealant for lead storage batteries and a preparation method thereof, in particular to an adhesive suitable for sealing and bonding lead storage batteries. Background technique [0002] With the increasing shortage of energy in the international community, a new generation of transportation tools - electric bicycles came into being. Because of their low price, lightness and beauty, and no exhaust pollution, they are gradually accepted by the general public. The current domestic annual output reaches 50 million. Foreign consumption is also gradually interested, so the annual demand for lead-acid batteries for mopeds is considerable. In addition, the demand for lead-acid batteries in related large-scale industries such as UPS lead-acid batteries and solar energy storage batteries has grown by leaps and bounds, and is growing at a rate of doubling every year. Adhesives for lead-acid batteries were mainly produced in...
