Closed-hole type sound insulation and thermal insulation refractory plate and preparation method thereof

Abstract

The invention discloses a closed-hole type sound insulation and thermal insulation refractory plate and a preparation method thereof. The closed-hole type sound insulation and thermal insulation refractory plate comprises a basic material layer, an intermediate layer, a surface material layer, a surface glaze layer, a decorative layer and a protective glaze layer, the intermediate layer is arranged above the basic material layer, the intermediate layer is internally provided with uniformly arranged holes, and the holes are each of a unique closed-hole structure. The closed-hole type sound insulation and thermal insulation refractory plate has the properties of fire resistance, flame retardance, acid and alkali resistance of traditional ceramic products, and has the characteristics such aslight weight, sound insulation and thermal insulation. Glazed waste mud in the ceramic industry and difficult-to-handle polishing recycled materials are used as main raw materials to prepare green energy-saving products, waste materials are utilized, the decoration needs are met, the building load is reduced, and comprehensive consumption of building ceramics on resources, energy and social resources is reduced. The thermal expansion coefficients and the shrinkage ratios of basic materials, intermediate materials and surface materials are close to each other, the interlayer stress can be reduce, the flatness of the closed-hole type sound insulation and thermal insulation refractory plate is ensured, deformation in a later stage is avoided, and the production quality of the closed-hole typesound insulation and thermal insulation refractory plate is enhanced.

Description

technical field [0001] The invention relates to the technical field of utilization of building ceramic waste, in particular to a closed-cell sound-insulation and heat-resisting refractory plate and a preparation method thereof. Background technique [0002] The ceramic industry will produce a large amount of polishing waste in the process of grinding and polishing. This kind of polishing waste has a very fine particle size and is dispersed after air drying. It is easy to fall everywhere with the wind, which will seriously threaten the health of the surrounding people and cause The compaction of the surrounding land leads to serious environmental pollution, and the landfill of polishing waste not only consumes manpower and material resources, but also pollutes the groundwater quality. According to statistics: on average, about 1.5 kg of brick chips will be formed for every square meter of polished brick produced. At the same time, the loss of abrasive tools is about 0.6 kg. I...
