A refractory material generally refers to an inorganic material that can withstand temperatures above 1580 °C. They are building kiln, combustion chambers and other building materials that require high temperature resistance. Generally made of quartz sand, clay, magnesite, dolomite, etc., it is a component inorganic coating with temperature resistance of -80-1800 °C and thermal conductivity of 0.03W/mK, which can suppress high temperature objects. And the heat radiation and conduction heat of low temperature objects, can maintain 70% of heat for high temperature objects without loss. In addition, the high temperature resistant thermal insulation coating is also characterized by insulation, light weight, convenient construction and long service life. It can also be used as an inorganic material for high temperature and acid and alkali resistant glue, and the attached object is firm. Such as refractory cement, magnesium bricks, etc. In a broad sense, inorganic refractory and heat-resistant materials mean that these compounds have high hardness, good brittleness, good chemical corrosion resistance, and a melting point of more than 1500. For example, high-temperature glass is also a refractory material.
The heat resistant polymer can be used as a high temperature resistant film insulating material, a high temperature resistant fiber, a high temperature resistant coating, a high temperature resistant adhesive, and the like. According to the time of high temperature resistance, it is divided into instant high temperature resistant materials and long time high temperature resistant materials. The former can withstand a few seconds to a few minutes at 1000 to 10000 °C. The ablative material is also a high temperature resistant material. For example, at 300 to 600 ° C, it can maintain its mechanical strength, chemical resistance and the like in the air.
