Description
Technical Field
The invention belongs to the technical field of coatings, and particularly relates to an insulating wear-resistant coating capable of being used for a common plate substrate, an aluminum electrolytic cell cover plate or an aluminum electrolytic cell shell, and a preparation method and application thereof.
Background
The coating is a multifunctional material which can play a role in protecting or endowing a special function and the like when being coated on the surface of an object. The insulating wear-resistant paint is endowed with insulating wear-resistant functions.
With the development of society, various types of devices are increasing, and insulation materials and insulation technologies for the devices are receiving increasing attention. Wherein, for the cover plate of the aluminum electrolytic cell and the shell of the aluminum electrolytic cell, the insulating material and the insulating technology directly influence the safety and the reliability of the operation equipment, and play a vital role in technical and economic indexes and the operation life.
At present, the cover plate of the electrolytic cell is usually a common aluminum alloy cover plate, and the shell of the electrolytic cell is an iron shell. In order to prevent the connection between the cell cover and the cell casing from being electrically energized during the operation of the electrolytic cell, measures are often taken which mainly comprise: (1) an insulating material is arranged outside the bottom of the slot cover plate close to the slot shell, but the insulating material can cause exposed damage along with the deformation of the slot cover plate; (2) the insulating bricks are arranged between the bottom of the cell cover plate close to the cell shell and the cell shell, but the positions of the insulating bricks can be changed continuously along with the use of the cell cover plate, thereby increasing the workload of an electrolysis worker.
In addition, the contact part of the edge of the tank cover plate and the electrolytic tank is easy to wear, and how to increase the insulativity between the bottom of the tank cover plate and the tank shell and the wear resistance of the tank cover plate and the tank shell is a technical problem to be solved urgently.
Chinese patent CN106011933A discloses a novel aluminum cell sealing heat-preservation cell cover plate, wherein a large-area cell cover plate formed by sequentially and seamlessly assembling an A-type cell cover plate and a B-type cell cover plate is described, and corner cell cover plates seamlessly assembled with the large-area cell cover plate are arranged on two sides of the large-area cell cover plate; the cover plates of the A-type groove and the B-type groove respectively comprise assembled aluminum profiles positioned at two sides of the groove cover plate and a supporting aluminum profile positioned in the middle of the groove cover plate; an upper aluminum plate and a lower aluminum plate are fixedly riveted between the assembling aluminum profile and the adjacent supporting aluminum profile, and a heat-insulating layer is filled between the upper aluminum plate and the lower aluminum plate. According to the technical scheme, the service cycle of the cover plate is prolonged on the basis of sealing and heat preservation, the sealing and heat preservation effect is good, the strength is high, the weight is light, the service life is long, and the insulation effect is good. However, the technical solution cannot avoid the damage of the insulation layer and the insulation caused by the deformation of the slot cover plate.
Chinese patent CN201358313Y discloses a novel aluminum cell hood trough cover plate insulation structure, which is constructed by an aluminum cell upper horizontal hood steel plate, a hood trough cover plate and an upper hood insulation member. According to the technical scheme, the smoke hood insulation component constructed on the upper horizontal smoke hood steel plate is used for insulation for one time, and two insulations at the upper end and the lower end of an original smoke hood groove cover plate are replaced. The technical scheme has the advantages of simple structure and manufacture, reduced manufacturing cost, and adaptation to the working conditions of low voltage, large current and high temperature resistance of the electrolytic cell, but the insulation structure is relatively complicated, and wastes time and labor.
At present, the research on the insulating material is still a weak link, an effective technical means is lacked, and the research and development of an insulating wear-resistant material which is environment-friendly, low in economic cost, convenient and fast to construct and excellent in using effect is urgently needed.
