Anti-fouling ceramic tile with sound absorption/absorption function and preparation method thereof

Abstract

The invention discloses an antifouling ceramic tile with a sound absorption / adsorption function. The antifouling ceramic tile with the sound absorption / adsorption function is composed of an intermediate layer and an outer wrapping layer, wherein the intermediate layer and the outer wrapping layer are both of a porous structure. The intermediate layer is nested in the outer wrapping layer, the outer wrapping layer is composed of a surface layer and a groove-shaped bearing layer, and the outer wrapping layer wraps the intermediate layer. The thickness, pore diameter and porosity of the intermediate layer are all greater than that of the outer wrapping layer. The invention further discloses a preparation method for the antifouling ceramic tile with the sound absorption / adsorption function. According to the antifouling ceramic tile with the sound absorption / adsorption function and the preparation method thereof, a nested structure is adopted, the porosity of the intermediate layer is higher than that of the outer wrapping layer, The sound absorption, adsorption and antifouling functions are realized effectively, and the antifouling ceramic tile is high in strength and easy to pave andpaste. The preparation method is simple, raw materials are easy to obtain, formed pug is good in plasticity and ductility, and easy to form and sinter, products are stable in quality and quite good inperformance, and the progress and application development of functional ceramic tile technology is facilitated.

Description

technical field [0001] The invention relates to the technical field of building ceramic materials, in particular to a ceramic brick with sound absorption / adsorption function and a preparation method thereof. Background technique [0002] With the improvement of living standards, people put forward higher requirements for interior decoration, not only requiring architectural tiles to have a good decorative effect, but also hoping to have other functions, such as self-cleaning, anti-fouling, adsorption, noise reduction, etc. At present, the most commonly used sound-absorbing materials are porous materials (such as glass wool, slag wool, foam plastics, asbestos wool, felt, wood wool board, soft fibers, microporous sound-absorbing bricks, etc.), which are mainly divided into three types in terms of shape: There are three types of fibers, foams and particles. Inorganic fibers mainly include glass wool, glass wool, slag wool, rock wool and their products, etc. These inorganic mat...

Problems solved by technology

However, the preparation method of this composite structure is too cumbersome, and because it adopts a multi-layer structure, it is loose and has low strength; at the same time, it needs to use adhesives, which increases the possibility of indoor pollution

[0004] In addition, although the porous structure of the above-mentioned sound-absorbing materials can also be used as an insulation or adsorption layer, most of them are currently multi-layer composite, and the composite effect is only simple composite; at the same time, once the dust enters the brick Difficult to remove from the body, poor anti-fouling performance

Therefore, this type of ceramic tile in the prior art does not take into account the functions of sound absorption, adsorption and anti-pollution, and structurally, the structure of multi-layer superposition is still not changed.
