Abstract

The invention discloses the production technologies that the insulation strip of smelting industry electrolytic cell cathode plate, liquid level insulating layer, stripping mouth integral die vulcanize.The production technology be first produce these insulation strips, liquid level insulating layer, remove mouth material be can be corrosion-resistant, the polymer that chemical crosslinking generates reticular structure itself can occur, and the Kai Muluoke (Chemlok) that these polymer can be also covered with applying in advance on cathode plate is chemically crosslinked, cathode plate together with insulation strip, liquid level insulating layer, stripping mouth firm connection, is become indivisible entirety by this chemical bond.Core of the invention is this negative plate insulation bar of production, liquid level insulating layer, stripping mouth, refers to the processing method that integral die vulcanizes in vulcanizer.To change in the past with linear molecule polymer (plastics) cold bonding on cathode plate, simple physical bond, which inevitably has the gap, causes acid solution to leak into, cathode plate corrosion cause to be glued polymer fall off, jackknifing, need the situation for expending a large amount of manpower and materials repairs.Cathode plate produced by the invention is substantially not required to repair, has saved a large amount of manpower and materials, substantially increases the service life of cathode plate.

Description

The integral die sulfurization technology of negative plate insulation bar, insulating layer
Technical field
The present invention relates to the negative plate insulation bar of the metals such as smelting industry electrolytic zinc, copper, lead, nickel, liquid level insulating layer, strippings The production technology of mouth integral die vulcanization.
Background technology
Insulation strip, liquid level insulating layer, stripping mouth are all to use the methods of cold bonding, injection, insulation on existing cathode plate Item and insulating layer are also all plastics (such as PP, PE) extrusion moldings using linear structure, then on cathode plate and insulation strip Sticky surface adhesive for spraying or resin, then they are bonded together by hand.Since artificial governing factor is big, inevitably bond not Jail has the gap, and acid solution, which easily penetrates on cathode plate, corrodes, in addition this bonding force is single physical adhesion, with Temperature change is expanded with heat and contract with cold so that adhesive loosening failure, causes insulation strip, insulating layer to fall off, in addition this linear structure is exhausted The easy heat ageing of edge strip so that the brittle easy fracture of insulation strip, cathode plate can not work, with the insulation strip that this plastics are raw material production The adhesive method generally existing above problem by hand will expend a large amount of manpower and materials repair insulation strips, insulating layer in smeltery, A large amount of cathode plate causes to scrap because of periphery seriously corroded.
Invention content：
The object of the present invention is to provide a kind of corrosion-resistant, heat-proof aging and chemistry interlinkage generation network structure can occur Polymer, and a kind of process polymer and the vulcanization of cathode plate integral die is provided, equipment is used in technic index Instrument control is different from the simple of passage in the past to ensure insulation strip, liquid level insulating layer, stripping mouth and cathode plate seamless combination Physics cold bonding method.
Also to be resistant to strong acid burn into resistance to for the polymer of reticular structure that chemistry interlinkage generation consolidates that can occur of the present invention itself Heat ageing.These polymer have butadiene acrylonitrile rubber, ethylene propylene diene rubber, butyl rubber, chlorosulfonated polyethylene etc., in order to increase corrosion resistance Plastics such as polyvinyl chloride, polypropylene, polyethylene etc. can be also selected to be used in combination therewith.General proportion is that rubber is 70 parts (mass ratioes), Plastics are 30 parts (mass ratioes), and crosslink agent DCP etc. is then added, polymer semi-finished product are made.The present invention is most importantly：Cathode Insulation strip, liquid level insulating layer on plate, stripping mouth be with made of the vulcanization of cathode plate integral die.This production method technique skill Art is the first structure design according to cathode plate and production and processing mold, it is ensured that insulation strip, liquid level insulating layer, the geometric form for removing mouth Shape and size meet requirement.It places the mould into and is heated to set point of temperature in vulcanizer, so that it may above-mentioned for use is gathered It closes and is successively put into die cavity after object semi-finished product sanction item is weighed with cathode plate, it is netted that press cure makes polymer generation chemical crosslinking be formed Structure and polymer are chemically crosslinked with the polar group for vulcanizing the preceding Kai Muluoke (Chemlok) coated on cathode plate, Firm chemical chain is formed to combine.This chemical chain is more much bigger than simple physical bond intensity, and peel strength reaches 4.5Mpa.
The technical process of the present invention is such：First the roller temperature of control mixing facilities makes butadiene acrylonitrile rubber mould no more than 60 DEG C Change, is then warming up to 120 DEG C again, then put into polyvinyl chloride, is allowed to mix well, be subsequently added into reinforcing agent, anti-aging agent and friendship Join agent etc., it is for use that last slice cuts required size.Vulcanizer temperature is controlled at 155 DEG C ± 5 DEG C, first carries out physics to cathode plate And chemical treatment, coating Kai Muluoke (Chemlok) are placed into die cavity and are heated, after temperature reaches mould temperature, place into and cut Good rubber and plastic polymer is forced into 9Mpa pressure, and vulcanization time is 25 minutes can depanning.Insulation strip, liquid on cathode plate Face insulating layer, stripping mouth just machine simultaneously.
The present invention process conditions be：
Kneading machine roller temperature is controlled in softened rubber at 60 DEG C, is warming up to 120 DEG C, after mixing well when plastics are added, roller Temperature control system adds reinforcing agent carbon black, anti-aging agent, activating agent, vulcanizing agent etc. at 60 DEG C.The technique item of integral die sulfidization molding Part is that vulcanizer plate temperature (mold temperature is same) is 155 DEG C ± 5 DEG C, and vulcanizer pressure is 9Mpa.Sulfurizing time (is formed steady Gu the reticular structure time) it is 25 minutes.In accordance with the technical process and process conditions and raw material proportioning of the present invention, through integral die sulphur Insulation strip, liquid level insulating layer, stripping mouth on the cathode plate of change.Its every physical mechanical property is as follows：1, it is 120 DEG C in temperature Ageing oven in 72 hours aging coefficients be 0.96.2,72 hours weight loss at a temperature of 40 DEG C are immersed in 75% sulfuric acid It is 0.3%.3, it is 4.5Mpa with the peel strength of metallic cathode plate.
Specific embodiment：
Implementation ratio：30 activating agent (zinc oxide) of butadiene acrylonitrile rubber 70 (mass parts) polyvinyl chloride, 5 plasticizer (stearic acid), 2 reinforcement 60 anti-aging agent RD 2 of agent (spray carbon black) sequentially adds after weighing above-mentioned raw materials and is kneaded uniformly, cuts into item, then with cathode Plate is put into carries out whole vulcanization in vulcanizer together in mold.The peel strength of polymer and metallic cathode plate reaches 4.5Mpa forms firm not strippable entirety.
Following table is example 2-8, lists raw material proportioning, process conditions and physical mechanical property index：
Insulation strip, liquid level insulating layer, stripping mouth heat-proof aging on cathode plate caused by above-mentioned technical process, corrosion resistant Erosion, with cathode plate seamless combination, acid solution can not leak into negative plate insulation region without being corroded.Therefore, the insulation of cathode plate Since item, liquid level insulating layer, stripping mouth are scrapped overall process substantially to cathode plate using and need not be repaired, and a large amount of people have been saved Power material resources, meanwhile, also greatly improve the service life of cathode plate.
