One-way water-permeable foamed ceramic regenerated material and preparation method thereof

Abstract

The invention discloses a unidirectional water-permeable foamed ceramic regenerated material and a preparation method thereof, comprising a foamed ceramic layer, a porcelain stone interface layer and a porcelain particle water-permeable layer which are sequentially stacked and fired simultaneously. The invention effectively combines the water-permeable porcelain particle layer with the water-impermeable foamed ceramics. When used as a ground material, the surface is wear-resistant, water-permeable and water-conducting, and non-slip. It is the preferred material for hydrophobic and anti-slip in public places and pedestrian passages; as a wall material When in use, it has sound insulation and sound absorption, heat preservation, fire resistance and burn resistance, and can meet the multifunctional requirements of partition walls in many public places at the same time.

Description

Technical field [0001] The present invention belongs to the technical field of building materials, specifically relates to a one-way permeable foam ceramic recycled material and a preparation method thereof. Background [0002] The production of lightweight foam ceramic partition board and insulation board has lightweight, thermal insulation, compression resistance, anti-folding, fireproof, waterproof, sound insulation and other functions, and has the effect of environmental protection and energy saving, can be used as a building wall material or used for external wall decoration, to achieve the goal of building weight reduction and energy saving. However, in the actual application process, the characteristics of the product and the requirements of the application scenario do not match the situation from time to time. [0003] Due to the brittleness and density of foamed ceramics and the close relationship between thermal insulation performance, so that the products of a single d...

AI Technical Summary

Problems solved by technology

[0003] Due to the brittleness of foamed ceramics and the close correlation between density and thermal insulation performance, products with a single density and structure cannot be directly applied to building structures, such as: 1) Thermal insulation board products: The thermal conductivity of existing products is lower than 0.055w / m·k foamed ceramics, its density is less than 200Kg / cubic, its compressive strength is less than 1Mpa, the fire resistance and penetration resistance of 10 cm thick is less than 1 hour, and the sound insulation is 30db, which cannot meet the strength and sound insulation of building wall materials, etc. 2) Partition wall panel products: The density of the existing products is 400Kg / cubic, the compressive strength is greater than 6Mpa, the thermal conductivity is higher than 0.12w / m·k, and the fire resistance and penetration resistance of 10cm thick are less than 2 hours. Unable to meet the national building exterior wall insulation and fire resistance limit industry standard requirements

3) The brittleness of foamed ceramics makes the nail holding power of the product insufficient and easy to loosen

The surface of the product has low wear resistance, is easy to scratch, and is easy to fall off ash

When used as a building material, it is difficult to install and there are potential safety hazards

[0004] In summary, the advantages of foamed ceramics with a single density and structure are not prominent in practical applications, their weaknesses are magnified, and their strengths are covered up, which leads to the development of the entire industry encountering bottlenecks when entering the application field. Therefore, it is necessary to develop a multifunctional Multi-structure foamed ceramic products overcome the above defects and eradicate potential safety hazards to meet market needs
