Abstract

The invention relates to a high-temperature-resistant binder. The high-temperature-resistant binder comprises the following components in percentage by weight: 35-40% of a sodium silicate water solution, 50-57% of kaolin with ultralow alkali metal content and 8-10% of kyanite powder. The preparation method comprises the following steps: adding the high-modulus sodium silicate and water into a high-speed dispersing machine according to a ratio, and fully dispersing; then adding kaolin with ultralow alkali metal content, and dispersing for 10 minutes at a high speed; finally adding the kyanite powder, slowly stirring for 1 minute, discharging, and finally sealing and packaging. The high-temperature-resistant binder disclosed by the invention is non-toxic and harmless, is friendly to a human body and environment, and is high in fire resistance and high in bonding strength, the bonding strength in any one temperature interval between the normal temperature and the highest use temperature is more than 2 MPa, the defect that most binders have no bonding strength at the temperature between 650 DEG C and 1000 DEG C is overcome, bonding between different materials can be realized; compared with an existing binder, the binder is more convenient to use, and the construction efficiency is improved.

Description

technical field

[0001] The invention belongs to the technical field of binder materials, and in particular relates to an inorganic composite binder for high temperature resistant materials. Background technique

[0002] Adhesives are used in the bonding and masonry of refractory materials in various high-temperature kiln masonry. The high temperature resistance of the adhesive is one of the important factors affecting the strength of refractory materials. The bond strength of the adhesive is one of the main factors affecting the structural integrity and tightness of the kiln. The bonding strength of ordinary adhesives comes from the soft clay in the ingredients, and the soft clay has no strength at all in the middle temperature range of 650-1000 °C because the crystal water has disappeared but has not yet reached the sintered state. Therefore, it cannot meet the requirements for use in the middle temperature section of a medium temperature kiln or a high temperature kiln. ...
