Embodiment 1

[0014] To seal the battery, follow the steps below:

[0015] (1) Prepare the two components of the sealant according to the following raw materials in parts by weight: component A: 501 diluent 12-18, bisphenol A epoxy resin 52-68, component B: flexible epoxy resin 20 ~32. Compound amine epoxy curing agent 40~50; Stir components A and B separately;

[0016] (2) Before use, make a sealant by mixing component A: component B = 100: (40-50) according to the following weight-by-weight ratio;

[0017] (3) Put the sealant into a constant temperature box and heat it to make it flow, and pour the sealant into the extrusion pot;

[0018] (4) Correct the seat, put the battery tank flat in front of the front, squeeze the sealant into the glue tank of the battery tank with a squeeze pot, and move evenly, so that the sealant flows into the tank without leaving air holes to prevent acid leakage; The amount should be 0.3-0.6 mm higher than the glue tank;

[0019] (5) Check whether there are...

Embodiment 2

[0022] The difference between this example and Example 1 is that the two components of the sealant are prepared according to the following raw materials in parts by weight: component A: 501 diluent 14-16, bisphenol A epoxy resin 54-58 , B component: flexible epoxy resin 25 ~ 30, compound amine epoxy curing agent 45 ~ 48; and A, B two components were stirred evenly; (2) according to the following weight ratio before use A component: B component = 100: (45 ~ 50) combined to make a sealant; other steps are the same as the first embodiment.

Embodiment 3

[0024] The difference between this example and Example 1 is that the two components of the sealant are prepared according to the following raw materials in parts by weight: Component A: 501 thinner 15-18, bisphenol A epoxy resin 52-60 , B component: flexible epoxy resin 30 ~ 32, compound amine epoxy curing agent 40 ~ 45; and A, B two components were stirred evenly; (2) according to the following weight ratio before use A component: B component = 100: (40 ~ 45) combined to make a sealant; other steps are the same as the first embodiment.

Abstract

The invention relates to a sealing technology in the production of a storage battery, and concretely relates to a sealing method of the storage battery. The sealing method comprises the following steps: 1, preparing two components of a sealing gum according to a case that the two components comprises a component A and a component B, the component A comprises, by weight, 12-18 parts of a 501 diluent and 52-68 parts of a bisphenol A epoxy resin, and the component B comprises, by weight, 20-32 parts of a flexible epoxy resin and 40-50 parts of a composite amine epoxy hardener; 2, preparing the sealing gum by mixing the component A with the component B according to a weigh part ratio of 100:(40-50); 3, heating the sealing gum to make the sealing gum flow; 4, squeezing the sealing gum into a gum slot of a cell slot until that the height of the sealing gum is 0.3-0.6mm higher than the height of the gum slot; 5, checking that whether there are pores in the sealing gum, whether positions of an anode and a cathode are correct and stationary, and whether the anode and the cathode extend out of a cover bottom; and 6, covering with a battery cover, and continuously laying aside for 12-15h to make the sealing gum be complete dryness. The sealing method of the invention solves problems of the difficult guaranteeing of sealing performances of the storage battery and an acid leakage phenomenon of a terminal, wherein the problems exist in present technologies.

Description

technical field [0001] The invention relates to a manufacturing process of a battery, in particular to a glue sealing process in the production of the battery. Background technique [0002] The sealing of the battery output terminals is critical. At present, the terminal protective cover is directly inserted into the groove of the battery cover. The general method is to pour the sealant in the groove, and pour the sealant again after the protective cover is inserted and cured. However, the existing sealing methods are difficult to ensure the sealing performance of the battery, and sometimes cause acid leakage from the terminals. Contents of the invention [0003] The object of the present invention is to provide a sealing method for storage batteries. The present invention solves the problem that it is difficult to ensure the sealing performance of storage batteries in the prior art and sometimes causes acid leakage from terminals. [0004] The sealing method of the stor...
