Method for preparing calcium-aluminum-silicon (CAS) glass ceramics by quickly sintering waste lamp tube glass

The invention discloses a method for preparing calcium-aluminum-silicon (CAS) glass ceramics by quickly sintering waste lamp tube glass, belonging to the building decorative material field. The method comprises the following steps of: (1), melting, water-quenching, grinding and screening the waste lamp tube glass to obtain glass powder; (2), adding proper quick lime to satisfy CAS glass ceramics component requirement; and (3), pressing and molding the uniformly-mixed powder material and sintering the powder material in a quick warming furnace to obtain the CAS glass ceramics. By taking the waste lamp tube glass powder as a main material and using the quick sintering process to process the CAS glass ceramics, the method has the characteristics of low material cost, low sintering temperature, short sintering time and high bending strength of the bending strength, and the like, achieves environment protection, energy saving, high added value and large-scale recycling of the waste lamp tube glass, and has notable
