Abstract

The invention provides ceramic powder comprises the following components in parts by mass: 30-60 parts of metakaolin, 10-30 parts of potassium / albite, 10-30 parts of low-melting-point glass powder, 30-50 parts of zinc borate, 5-15 parts of fumed silica and 0.5-2 parts of a surface modifier. According to the particle size effect of ceramic sintering, the particle size of a filler is refined, and meanwhile, the particle size among the components is also homogenized, so that the effect of sintering into ceramic is obviously improved. In addition, by adding self-made low-melting-point glass powder, the ceramic forming performance of the ceramic polyolefin at medium temperature and high temperature is improved, the strength of the ceramic powder and a PVC board after ceramic forming is higher,and a ceramic body formed by sintering has fewer cracks and is small in deformation.

Description

technical field [0001] The invention belongs to the field of processing and application of inorganic composite powder, and relates to the research and development of a polymer-based refractory material, in particular to a vitrified powder and its application in the prepared refractory PVC board after it is blended with PVC resin . Background technique [0002] Porcelain powder is an inorganic composite powder that can quickly form porcelain in a wide temperature range (400-1000°C). It is very different from traditional ceramic powder. The sintering characteristic of traditional ceramic powder is temperature High (≥1200°C), long holding time, and relatively strict requirements on heating rate and sintering atmosphere, it is not suitable for application in extreme environments (such as fire). According to the principle of liquid phase sintering, the original ceramic powder is improved to improve the performance of low-temperature porcelain formation, so as to meet the needs o...
