Sticking glue for sticking electrolytic zinc cathode plate insulation bar and production process of sticking glue

Abstract

The invention discloses sticking glue for sticking an electrolytic zinc cathode plate insulation bar and a production process of the sticking glue. The sticking glue consists of a component A and a component B, which are mixed according to a weight ratio of 1:1, wherein the component A comprises polyfunctional epoxy resin, HTBN (hydroxy-terminated butadiene-acrylonitrile), hydroxyl-terminated polysulfide rubber, talcum powder, an antioxidant, gas-phase silicon dioxide, barium sulfate and a defoaming agent, and the component B comprises polyamide, a talcum powder, a modified aliphatic amine curing agent, polyamine-thiourea polycondensate, an aminosilane coupling agent, a curing promoter, a flexibilizer, gas-phase silicon dioxide and a defoaming agent. By optically selecting and reasonably matching raw materials of different properties, the prepared sticking glue can be rapidly cured at the room temperature, the sticking strength of the sticking glue after being cured is high, and the sealing property is good; meanwhile, the sticking glue has excellent acid corrosion resistance, excellent aging resistance and excellent current impact resistance; and moreover, the sticking glue is low in cost, simple and convenient to construct, low in storage requirement, non-toxic, harmless and very suitable for sticking the electrolyte zinc cathode plate insulation bar.

Description

technical field

[0001] The invention relates to the technical field of insulation wrapping of electrolytic zinc cathode plates, in particular to an edge adhesive for bonding insulating strips of electrolytic zinc cathode plates and a production process thereof. Background technique

[0002] In the wet electrolytic zinc smelting process, in order to separate the cathode plate into two mutually independent electrodeposition surfaces, in order to facilitate the stripping of the electrolytic layer and avoid the short circuit between the cathode and the anode, it is generally necessary to bond on both sides of the cathode plate insulation strips. Because the insulating strip is in the environment of strong acid corrosion and current impact at about 50°C for a long time, and there will be strong mechanical vibration during mechanical stripping, the insulating strip is very easy to loose or fall off due to corrosion and vibration, and it will seriously affect the normal operation w...
