Abstract

The invention provides graphite fireproof binder. The binder is prepared from graphite powder, adhesive, curing agent, enhancer, dispersing agent, toughening agent and water. The invention further provides a preparation method of the graphite fireproof binder. Compared with the traditional graphite mending agent, the graphite fireproof binder not only can accomplish the mending on the graphite structural element, but also can guarantee the stability of the structure under a high-temperature working condition; the fireproof adhesive is simple in preparation method, non-harsh in condition, low in environment requirement, and strong in applicability. The graphite fireproof binder provided by the invention cannot react with the molten metal, and has more extensive application space on the graphite adhesion, and the current status that the high-temperature graphite mold can be formed only through the traditional machining process is changed.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a graphite refractory adhesive and a preparation method. Background technique [0002] Due to the limitation of repairing and bonding materials, the molding of high temperature resistant graphite molds is mainly completed by machining, which results in a lot of material waste and a long processing cycle. [0003] As a material with high thermal stability, graphite is very suitable for use as a mold material for ultra-high temperature metal melting. In the process of being used as an ultra-high temperature metal smelting mold, a repair agent will be required according to the working conditions. In the prior art, CN105713513A discloses an alloy additive for casting repair. The raw materials include waste engine oil, silicone resin, polyether ether ketone, epoxy soybean oil, nitrile rubber, carrageenan, hydrogenated castor oil, zeolite powder, asbestos Powder, microp...
