High-porosity thin microporous composite ceramic plate and preparation method thereof
The invention discloses a high-porosity composite ceramic plate, which is composed of a matrix layer, a transition layer and a nano metal particle surface layer, the transition layer is a combinationlayer of the surface layer and the matrix layer and is used for forming a transition plane between a microbubble material and the metal particle surface layer, and the matrix layer structure containscombined closed pores with alternate large and small pores. And a cured metal coating is attached to the upper surface of the matrix layer, so that the matrix layer has antibacterial and bacteriostatic properties and photocatalytic degradation performance of organic pollutants. The ceramic plate is formed by secondary foaming and firing and comprises a low-temperature pre-foaming stage and a medium-high-temperature foaming stage, wherein the pre-foaming is completed by a granular organic foaming agent, and the medium-high temperature foaming is completed by a composite inorganic foaming agent.The prepared composite ceramic plate is high in closed porosity, low in heat conductivity coefficient and low in volume density, and the preparation method can effectively reduce the firing temperature and shorten the firing time.
本发明公开了一种高致孔率的复合陶板，由基体层、过渡层及纳米金属颗粒表层构成，所述过渡层为表面层与基体层的结合层，用于形成微泡材料与金属颗粒表层之间的过渡平面，所述基体层结构中含有大小气孔相间的组合闭气孔。上表面附着固化金属涂层，具有抗菌抑菌和有机污染物的光催化降解性能。本发明所述陶板采用二次发泡烧制而成，包括低温预发泡阶段和中高温发泡阶段；其中预发泡由颗粒型有机发泡剂完成，中高温发泡由复合型无机发泡剂完成。所制得复合陶板闭气孔率高、导热系数低、体积密度低，制备方法可有效降低烧制温度和减少烧制时间。
