Problems solved by technology

[0003] The existing process of producing porous ceramics by foaming technology, but because there are a large number of closed pores inside the ceramic material, when exposed to a continuous flame, the gas in the closed pores expands, causing stress on the closed pores, and when it reaches its limit, it will Cracking, the entire foamed ceramics fall apart, lose integrity, lose its partition wall effect, and also lose its fire protection effect

Abstract

The invention discloses an anti-cracking porous ceramic material and a preparation method thereof. The ceramic material is prepared from the following raw materials in parts by weight: 30 to 40 parts of potassium feldspar, 20 to 30 parts of albite, 3 to 5 parts of manganese mud, 8 to 12 parts of yellow mud, 3 to 5 parts of talc, 0.2 to 0.4 part of silicon carbide, 0.4 to 0.6 part of adhesive, 0.2 to 0.4 part of interface agent, 0.5 to 1 part of plant ash and 0.8 to 1 part of titanium dioxide. Silicon carbide is used as a foaming material, and manganese mud is added at the same time. The porous ceramic material prepared from titanium dioxide, an adhesive, plant ash and other raw materials has greatly improved fire resistance, and reduces the phenomenon of internal cracking of pores; the physical and chemical properties of the ceramic are enhanced through aging treatment, and the surface layer of the ceramic is coated with an interface agent, so that the anti-cracking capability of the ceramic is further enhanced.

Description
