Problems solved by technology

However, due to the creep characteristics of polymer materials, especially when the temperature of the medium electrolyte is high, creep phenomenon is more likely to occur, so that the insulating sealing strip of the above structure is not clamped tightly, and the sealing strip and the cathode plate have to be clamped. Apply sealant to the junction, which not only increases the cost, but also easily causes the electrolyte to penetrate into the cathode plate of the sealing strip due to the weak adhesion between the sealant and the sealing strip itself, so that the metal is restored to the sealing strip , under the action of mechanical force during peeling, the sealing strip is accelerated and destroyed
[0004] It can be seen that the sealing strip has defects such as poor toughness, poor sealing effect, short life, and easy aging.

Embodiment Construction

[0023] The technical solution of the present invention will be described below in conjunction with the examples.

[0024] The materials used in the invention include: polyethylene resin, linear low-density polyethylene resin, functional polymer, antioxidant, metal deactivator, flow modifier, and appropriate amount of coloring agent.

[0025] The polyethylene resin is a copolymerized high-molecular-weight high-density polyethylene, and the requirements for various performance indicators are: the comonomer is α-olefin, and its density is ≥ 0.940g / cm 3 , Melt flow rate ≤ 1.0g / 10min.

[0026] The linear low density polyethylene resin is a copolymer, the comonomer is α-olefin, and its density is ≤0.926g / cm 3 , Melt flow rate ≤ 2.0g / 10min. The purpose of adding linear low density polyethylene resin is to further improve the toughness of the composition.

[0027] The modified material of the functional polymer ethylene copolymer or polyethylene, the comonomer of the ethylene copol...

The components used for producing the electrolysis cathode plate sealing strip include 100 parts of polyethylene resin, 0.1-20 parts of linear low density polyethylene, 0.1-10 parts of functional polymer, 0.1-1 part of oxidization inhibitor, 0.05-1 part of metal deactivator, 0.1-5 parts of flow modifier and a proper amount of colorant according to weight parts. The compound has the characteristics of long service life, high adhesion strength with a cathode plate and smooth surface of the molded sealing strip.

Description

technical field [0001] The invention relates to a polyethylene compound material for electrolytic cathode plate sealing strips and a preparation method thereof, which has the characteristics of good bonding performance with the cathode plate and long service life, and belongs to the technical field of plastic processing application and the technical field of wet electrolysis of copper and other metals. Background technique [0002] At present, the industrial production of high-purity copper, manganese, and zinc mainly adopts the method of electrolysis. Among them, an important production part is the cathode plate. Negative charges are introduced through the electrodes, and divalent copper ions, manganese ions, and zinc ions are reduced on the cathode plate to form copper, manganese, and zinc, and then the cathode copper is stripped off by the stripping unit to form High purity metal. The cathode plate is mainly made of stainless steel or titanium. In order to achieve the pu...
