NOVELTY - Acid and alkali corrosion resistant flame -proof plugging material comprises silicone oil, aluminum oxide, silicon dioxide, sodium fluorosilicate, calcium carbonate, sodium phosphate, calcium fluoride, carbon fluoride, silane coupling agent, foaming agent and binder. The preparation of acid and alkali corrosion-resistant flame -proof plugging material comprises (i) taking aluminum oxide, silicon dioxide, sodium fluosilicate, transferring to the platinum crucible to obtain the uniform glass melt, water quenching, drying and crushing to obtain the base glass particles, (ii) adding calcium carbonate and sodium phosphate, mixing and placing into the crucible, crushing and sieving to obtain the microcrystalline foam glass, (iii) taking the microcrystalline foam glass and fluorinated carbon, adding silane coupling agent to obtain the mixture and (iv) slowly adding the mixture into silicone oil and mixing uniformly to obtain the acid-alkali corrosion resistant flame -proof blocking material. USE - Used as acid and alkali corrosion resistant flame-proof plugging material. ADVANTAGE - The flame-proof blocking material has quickly foaming and expanding properties, tightly blocks the hole of the material, prevents further diffusion of smoke and flame and has good acid-alkali corrosion resistance and flame-proof performance and is connected with each other firmly, and whole structure is stable and has light weight characteristics.
