Embodiment Construction

[0021] The present invention proposes long-life electrolytic cathode plate sealing strip polyethylene compounding material and its preparation method. The materials it adopts include: polyethylene resin, linear low-density polyethylene resin, antioxidant, metal passivator, flow modifier , Appropriate amount of coloring agent.

[0022] The polyethylene resin is copolymerized high-molecular-weight medium-density or 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.

[0023] 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.

[0024] The antioxidant is a hindered phenolic substance, and its function is to capture the free radicals formed by h...

Abstract

The invention provides a compound used for a long-service-life electrolysis cathode plate sealing strip and a preparation method thereof, belonging to the technical field of plastic processing and application and the technical field of wet electrolysis of metals such as copper. 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, 0.1-1 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 and smooth surface of the molded sealing strip.

Description

technical field [0001] The invention relates to a long-life polyethylene compound material for electrolytic cathode plate sealing strips and a preparation method thereof, which has the characteristics of long life and good toughness, and belongs to the technical field of plastic processing and 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 purpose of insulation and reg...
