Technical Field
The invention belongs to the technical field of building materials, and particularly relates to a clay plate curtain wall reinforcing agent, a preparation method and application thereof.
Background
The ceramic plate curtain wall is a green building material prepared from natural minerals through vacuum high-pressure extrusion molding and high-temperature firing. Compared with the current mainstream practical glass curtain wall in China, the ceramic plate curtain wall and the heat insulation material are matched for use, so that the energy consumption of the building can be greatly reduced, the heat insulation and sound insulation effects are good, and the installation is firm. However, the ceramic plate curtain wall blank has poor air permeability and higher organic matter content, so that the ceramic plate curtain wall has long firing period, lower continuous kiln output and higher ceramic plate curtain wall price, and the ceramic plate curtain wall is greatly limited to be popularized and applied, thereby effectively improving the firing speed and reducing the firing period of products. The main solution for reducing the firing period is to greatly improve the strength of the ceramic plate curtain wall, and the key is to select a high-temperature reinforcing agent.
Patent CN1974487A is prepared by selecting B 2 O 3 、K 2 O and CaF 2 And (3) waiting for chemical raw materials, gradually forming a three-level reinforcing agent, and ensuring that the product has higher strength under the precondition of effectively reducing the sintering temperature of the ceramic. However, the use of the flux material can cause larger thermal stress to be generated in the clay plate curtain wall in the rapid cooling process, so that the strength of a sample is greatly attenuated instead, even the product is burst, or the strength attenuation phenomenon is generated in the later storage and transportation processes, so that the strength of the product cannot be effectively improved by singly improving the melt content in the high-temperature sintering process. Patent CN109650724a reduces the ceramic firing cycle by firing with lithium-containing compounds or the minerals spodumene and sojourn, etc. as raw materials to form a low coefficient of thermal expansion and low viscosity high temperature flux. Patent CN105236993A is Li 2 O、P 2 O 5 、B 2 O 3 And TiO 2 The high-temperature flux with low thermal expansion coefficient and low viscosity is formed for high-temperature melting of the raw materials, and is mixed with the ceramic bond for use. Lithium-containing compounds or mineral spodumenes and B 2 O 3 On the one hand, a large amount of melt phase is formed at a high temperature stage to promote sintering, and on the other hand, the addition of the components leads to the formed melt phase with a lower thermal expansion coefficient, so that the thermal stress generated in the curtain wall in the rapid cooling process can be greatly reduced, and the strength is greatly improved. Therefore, how to prepare a ceramic plate curtain wall reinforcing agent which can generate a certain amount of low thermal expansion coefficient in the sintering process of the ceramic plate curtain wall and realize large-scale mass production of the ceramic plate curtain wall reinforcing agent is important.
