Abstract
What the present invention relates to is to produce the used wedding agent of magnesia carbon refractory.Now not only remaining carbon is low for used wedding agent, and the refractory materials poor heat resistance made from its, and the life-span is short.The invention provides a kind of high softening-point oxidized bitumen resin modified phenol resin wedding agent.In order to make the magnesia carbon refractory of steel melting furnace furnace lining, the present invention can improve folding strength, ultimate compression strength, ablation resistance and the life-span of refractory materials.
Description
What the present invention relates to is to produce the used wedding agent of magnesia carbon refractory.
The used wedding agent of magnesia carbon refractory has pitch, resol, resole, powdered phenol-formaldehyde resin and resin modified phenol resin at present.These wedding agents not only remaining carbon are low, and the refractory materials poor heat resistance made from its, and the life-span is short.
In order to overcome the shortcoming of prior art, the present invention adds the high softening-point oxidized bitumen in the resol according to certain proportioning, the liquid wedding agent of a kind of high softening-point oxidized bitumen modified phenolic resins that obtains through technological process such as batch mixing, intensification, stirring, the degassing, insulation, cooling.
The present invention is a kind of liquid of good fluidity at normal temperatures, and the remaining carbon height all has good perviousness, wetting property to refractory oxide and graphite.And behind the high temperature cabonization, can form embedded structure again, so the bonding strength height, resistance to thermooxidation is good.
The oxidized bitumen that the present invention is used, softening temperature are that 150-190 ℃ of purity is 100%.
The resol that the present invention is used is under an acidic catalyst effect, through addition and polyreaction, can be made into the resin that molecular-weight average is 400-800.It can be dissolved in solvent and itself is non-sclerous, so storage period is long.Wedding agent behind the oxidized asphalt modification must add an amount of solidifying agent, just can make it change chain-like structure into by linear structure, thereby forms the high goods of intensity.
The present invention has improved the carbon residue rate after refractory materials burns till, and because the carbonization of wedding agent has increased carbon in conjunction with density, has improved folding strength, ultimate compression strength, ablation resistance and the life-span of refractory materials.
The present invention easily realizes suitability for industrialized production, and not only material source is abundant, and technology is easily manufactured, and tooling device is common.The benefit that enforcement of the present invention brings for society for enterprise surely.
Embodiment:
Prescription
Material weight part
Resol 100
Oxidized bitumen 60-90
Solvent 80-100
Technological process
1. resol is added in the reactor, heat up, stir, outgas.
2. after outgasing one hour, continue to heat up, add oxidized bitumen then, treat that oxidized bitumen dissolves fully after, stop heating, insulation 30-60 branch.
3. solubilizing agent after lowering the temperature.
4. be cooled to the room temperature blowing.
Claims (2)
1, the used wedding agent of a kind of magnesia carbon refractory is characterized in that: with high softening-point oxidized bitumen modified phenolic resins, and the liquid wedding agent that process batch mixing, intensification, stirring, the degassing, insulation, process for cooling process are made.
2, high softening-point oxidized bitumen according to claim 1 is characterized in that: softening temperature is 150-190 ℃.
