Abstract

The invention provides waste sagger repairing coating and a use method thereof. The waste sagger repairing coating is prepared from the following raw material components in parts by weight: 30 to 70 parts of fused white corundum powder, 1 to 10 parts of mullite powder, 8 to 30 parts of binding clay, 0 to 5 parts of spodumene, 1 to 5 parts of zirconium oxide, 5 to 25 parts of alpha-Al2O3 micro powder, 1 to 20 parts of magnesium aluminate spinel powder, 2 to 8 parts of sol, 1 to 5 parts of a binding agent, 0.1 to 1 part of a water reducing agent and 16 to 22 parts of water. The using method of the waste sagger repairing coating comprises the steps of preparing the repairing coating, polishing a waste sagger and repairing the waste sagger to obtain a regenerated new sagger. The repaired waste saggar not only can be put into use again, but also is high in strength, high in corrosion resistance and good in thermal shock resistance. The recycling rate of the waste saggars is increased, and the problems of stacking difficulty and environmental pollution are reduced to a great extent.

Description

technical field

[0001] The invention relates to the technical field of recycling waste saggers, in particular to a paint for repairing waste saggers and a method for using the same. Background technique

[0002] As a new generation of green and environmentally friendly products, lithium-ion batteries have been widely used in new energy vehicles, which can effectively alleviate the energy crisis. Lithium-ion battery cathode materials have a crucial impact on the energy density and cycle life of lithium-ion batteries, and are an important part of lithium-ion batteries. The lithium battery cathode material must be roasted at a high temperature in a kiln during the production process. The specific process is to use a sagger as a raw material (specifically including lithium salts (such as LiCO 3 、LiNO 3 and LiOH·H 2 O, etc.), manganese salts (such as MnCO 3 and Mn(NO 3 ) 2 etc.), manganese oxides (such as electrolytic MnO 2 , Mn 2 o 3 and Mn 3 o 4 etc.) and nickel-coba...
