Heat-resistant flame-retardant ceramic slurry, aluminum plastic film and preparation method thereof

The invention discloses a heat-resistant flame-retardant ceramic slurry, an aluminum plastic film with a ceramic slurry coating and a preparation method thereof. The heat-resistant flame-retardant ceramic slurry is prepared from the following raw materials in percentage by mass: 2%-30% of solid matter and 70%-98% of dispersant, wherein the fixed substance is prepared from the following raw materials by mass percentage: 75 to 95 percent of ceramic material and 5 to 25 percent of adhesive. The invention improves the flame retardancy of the aluminum plastic film by coating a layer of high-temperature resistant ceramic slurry coating on the surface of the aluminum plastic film used as the outer package of the soft-clad battery, thereby improving the safety performance of the lithium ion battery. In addition, the ceramic slurry coating on the aluminum-plastic film has the ability of neutralizing acids in the electrolyte, so that the battery enhances the corrosion resistance of the electrolyte. 本发明公开了种耐热阻燃陶瓷浆料、具有该陶
