Quartz fireproof material

Abstract

The present invention relates to the technical field of the high temperature resistance of pipelines, more particularly to a quartz fireproof material, which comprises, by weight, 135-169 parts of quartz sand, 10-20 parts of boric acid, 10-15 parts of a lignin-sugar composition, 15-20 parts of a phenol formaldehyde resin, 45-60 parts of zirconium oxide, 20-25 parts of magnesium silicate, 20-30 parts of sodium silicate, 90-125 parts of magnesium oxide, and 90-125 parts of calcium oxide. According to the present invention, with the application of the lignin-sugar composition to partially replace the phenol formaldehyde resin to be adopted as the binder of the fireproof material, the binding effect in the fireproof material field is good, and the lignin-sugar composition has advantages of low preparation cost, no residue of harmful substances such as free phenol, free aldehyde, and the like, and environmental protection; and the fireproof material has advantages of stable performance and long service life, and can be used in an alkaline environment for a long time.

Description

technical field [0001] The invention relates to the technical field of pipeline high temperature resistance, in particular to a quartz refractory material. Background technique [0002] Refractory materials are inorganic non-metallic materials with a refractoriness of not less than 1580°C. The refractoriness refers to the Celsius temperature at which a refractory conical sample can resist high temperature without softening and melting under no load. However, it is not possible to fully describe refractory materials only by the definition of refractoriness, and 1599°C is not absolute. It is now defined as a material whose physical and chemical properties allow it to be used in a high temperature environment is called a refractory material. There are many kinds of refractory materials, which are usually divided into ordinary refractory materials (1580-1770°C), advanced refractory materials (1770-2000°C) and super-grade refractory materials (above 2000°C) according to their re...

Problems solved by technology

[0003] Most of the binders for refractory materials disclosed in the prior art use phenolic resins. Those skilled in the art know that phenolic resins have the advantages of high bonding strength and heat resistance as a refractory binder, but the refractory materials prepared by it are not only expensive High, also contains free phenols, free aldehydes, etc., which is not conducive to environmental protection

[0004] Refractory materials are widely used and play an irreplaceable role in the fields of iron and steel, non-ferrous metals, glass, cement, ceramics, petrochemical, machinery, boilers, light industry, electric power, military industry, etc. There are very few refractory materials, and the existing refractory materials under alkaline conditions basically do not have a long service life
