A kind of insulating material and its application of electrolytic inter-tank tutoring electric board

Abstract

The invention belongs to the field of insulating materials and particularly relates to an insulating material of an inter-groove assistant current-conducting plate for electrolysis and an application of the insulating material. The insulating material is prepared from the following components in percentage by weight: 55-63% of chloroprene rubber, 14-15% of modified PVC resin, 0.6-1.2% of an accelerant DM, 1-4% of an activating agent ZnO, 1-4% of an activating agent MgO and 18-21% of a reinforcing agent carbon black. The insulating material is used for preparing the inter-groove assistant current-conducting plate for electrolysis. According to the invention, mixing of rubber is carried out by adding a corresponding chemical assistant to obtain a semiproduct forming material; the semiproduct forming material is attached to a copper current-conducting plate subjected to surface sandblasting through brushing of an adhesive so as to vulcanized and compounded in a vulcanizing process to obtain an integrated structure which is applied to the inter-groove assistant current-conducting plate for electrolysis so as to form an inter-groove conducting device with a bump type main current-conducting plate. On the premise that guaranteeing constant distance between poles and uniform and stable inter-polar current by the conducting device are ensured, the pressure-resisting breakdown-resisting capacity of the insulating material is of more advantage and the insulating material further has excellent acid corrosion resistance and flame retardance.

Description

technical field [0001] The invention belongs to the field of insulating materials, in particular to an insulating material for an inter-tank guidance electric plate for electrolysis and an application thereof. Background technique [0002] Such as figure 1 As shown, in the prior art, the inter-tank auxiliary electric plate structure for electrolysis is composed of an insulating partition plate 1, a cathode auxiliary conductive plate 2 and an anode auxiliary conductive plate 3 through vulcanization and compounding into one structure, and the insulating partition plate 1 is divided into a bottom The insulation area 11 and the middle boss partition area 12, the cathode sub-conductive plate 2 and the anode sub-conductive plate 3 cover both sides of the insulating partition plate 1 respectively. [0003] At present, the insulating material used in the insulating partition plate 1 of the inter-tank counseling electric plate for electrolysis is T 2 -Y 4 Rubber / plastic composites...

AI Technical Summary

Problems solved by technology

[0003] At present, the insulating material used in the insulating partition plate 1 of the inter-tank counseling electric plate for electrolysis is T 2 -Y 4 Rubber / plastic composites, where they fall short: T 2 -Y 4 The rubber / plastic insulating material cannot guarantee that the insulation, acid resistance and flame retardancy of the bottom insulating area 11 meet the requirements when the thickness is less than 11mm. Since the thickness of the cathode auxiliary conductive plate 2 and the anode auxiliary conductive plate 3 is 4mm, the two auxiliary electric plates The total thickness of the side is greater than 15mm

Therefore, to guarantee T 2 -Y 4 The pressure resistance and breakdown resistance of rubber / plastic insulating materials meet the requirements of electrolytic production, but there are certain limitations on its size and thickness, which makes it difficult to form the boss of the main conductive plate in the inter-slot conductive device.
