Sheet metal conveying release agent and preparation method thereof

Abstract

The invention discloses a metal plate conveying isolation agent and a preparation method thereof. According to key points of the technical scheme, the metal plate conveying isolation agent is preparedfrom the following components: graphite, a dispersant, a suspending agent, an abrasion-resistant agent, an alkaline regulator, a preservative and water; the dispersant is prepared from sodium polyacrylate, sodium carboxymethylcellulose and gum; the suspending agent is prepared from microcrystalline cellulose and activated carbon; and the abrasion-resistant agent is carbon black. Through the dispersant and the suspending agent, the dispersity and high-temperature stability of the graphite can be improved; through cooperation of the carbon black and the gum, an isolation film formed on the surface of a copper plate has good abrasion resistance and is not prone to falling off either, the copper plate and a conveyor belt can be prevented from adhering, and thus the condition of a drawing stamp generated between the copper plate and the conveyor belt is reduced; and the raw materials are safe and low in toxicity, and the isolation agent is environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of release agents, more specifically, it relates to a release agent for conveying metal plates and a preparation method thereof. Background technique [0002] In the process of processing metal sheets (such as copper sheets), it is necessary to use high-temperature-resistant conveyor belts to transport high-temperature metal sheets. Because the temperature of copper sheets is very high, the temperature of both copper sheets and conveyor belts is relatively high during transportation. , resulting in easy adhesion between the metal sheet and the conveyor belt during transportation, so that the copper sheet cannot automatically fall off the conveyor belt, which affects the transportation effect; therefore, it is necessary to apply a layer of lubricating oil on the lower surface of the copper sheet The release agent makes it easier to separate the copper plate from the conveyor belt. [0003] In order to meet t...

[0002] In the process of processing metal sheets (such as copper sheets), it is necessary to use high-temperature-resistant conveyor belts to transport high-temperature metal sheets. Because the temperature of copper sheets is very high, the temperature of both copper sheets and conveyor belts is relatively high during transportation. , resulting in easy adhesion between the metal sheet and the conveyor belt during transportation, so that the copper sheet cannot automatically fall off the conveyor belt, which affects the transportation effect; therefore, it is necessary to apply a layer of lubricating oil on the lower surface of the copper sheet Release agent, so that the copper plate and the conveyor belt can be separated more easily

[0003] In order to meet the needs of production, the release agent must meet the following requirements: firstly, the release agent must have good high temperature resistance and isolation effect, and secondly, when the copper plate is separated from the conveyor belt, the copper plate cannot produce scratches with the conveyor belt, and when using this When using a release agent, it is necessary to minimize the volatilization of harmful gases; however, the existing release agents cannot meet the above conditions at the same time, so it is necessary to develop a new release agent
