    摘要： There are disclosed methods and compositions for room temperature hardening of phenolic resole resin refractory compositions containing a magnesium oxide hardening agent alone or together with an organic ester. The resin is a low viscosity, low molecular weight resin having a high free phenol content. The magnesium hardening agent has a surface area of at least 20 square meters per gram. The compositions provide adequate working times and room temperature hardening within 24 hours.

    摘要： A binder solution of a phenolic novolak resin in solvent, preferably furfuryl alcohol containing at least one chemical agent such as amines containing one to five, preferably two to four, nitrogen atoms, glycerine or mixtures thereof. Preferably, the binder solution contains about 0.2 to about 1.5 weight percent water. The binder solution is for binding refractory objects, preferably those containing doloma (calcined dolomite) aggregate. Methods of mixing these ingredients and using the mixture are also disclosed. Bricks made from the doloma aggregate mixed with the binder solution show good ambient temperature green strength and enhanced modulus of rupture after curing and coking.

    摘要： There are disclosed methods and compositions for retarding the room temperature gelation and eventual hardening of phenolic resole resins when such resins are mixed with lightburned magnesium oxide or magnesium hydroxide hardening agents with or without an ester functional hardening agent. Retardation of gelation and hardening is achieved by incorporating into said mixture a retarder compound such as one which decreases the solubility of magnesium in said mixture. Additionally, hardening at higher temperatures, thermal curing, coated abrasives, polymer concrete, and other methods and compositions of this invention are disclosed.

    摘要： A binder composition of a phenolic novolac resin and a (lower) alkoxylated triazine-formaldehyde resin curing agent is disclosed. The triazine resins have sufficient carbon atoms in the alkoxy groups so as to provide a curing agent having a water solubility of less than 15%. The binder cures at high temperatures so as to provide improved flow and prolonged workability to the composition. The compositions are useful in refractory applications having a need for high temperature curing agents such as for maintenance and repair within refractory vessels by gunning/spraying, manufacture of electrodes by the Soderberg method, and for use in blast furnace tap holes.
