Embodiment 1

[0023] The invention provides a special cement for building refractory materials for the furnace wall of a carbon roasting furnace. The special cement contains the following components: 40% of three-grade high-alumina clinker powder, 55% of special-grade high-alumina clinker powder, and the two are mixed Composite high-alumina clinker powder; 0.5% nano-silicon oxide, 1% silica fume, the two are mixed to form composite nano-powder; 0.5% potassium feldspar powder; 1% 925 cement as coagulant; 0.5% solid Aluminum dihydrogen phosphate, 0.5% solid sodium hexametaphosphate, and 1% solid water glass are mixed to form a composite chemical binder; 25% of water is added, and the above percentages are percentages by weight.

Embodiment 2

[0025] The invention provides a special cement for building refractory materials for the furnace wall of a carbon roasting furnace. The special cement contains the following components: 35% of three-grade high-alumina clinker powder, 30% of special-grade high-alumina clinker powder, and the two are mixed Composite high-alumina clinker powder; 2% nano-silicon oxide, 8% silica fume or silica powder, 15% aluminum powder, the three are mixed to form composite nano-powder; 1% silica powder; 1% soft raw material Clay; 1% potassium feldspar powder; 2% magnesia powder as coagulant; 1% liquid aluminum dihydrogen phosphate, 1% liquid sodium hexametaphosphate, 3% liquid water glass, the three are mixed to form a compound The chemical binding agent adopts an external addition method; for 4% external water, the above percentages are percentages by weight.

Embodiment 3

[0027] The invention provides a special cement for building refractory materials for the furnace wall of a carbon roasting furnace. The special cement contains the following components: 30% of three-grade high-alumina clinker powder, 40% of special-grade high-alumina clinker powder, and the two are mixed Composite high alumina clinker powder; 1% nano-silicon oxide, 5% silica fume or silicon micropowder, 4% aluminum micropowder, the three are mixed to form composite nanopowder; 2% silica powder or quartz powder; 1% Soft raw clay; 5% potassium feldspar powder; 5% 925 cement as coagulant; 2% liquid aluminum dihydrogen phosphate, 1% liquid sodium hexametaphosphate, 4% liquid water glass, the three are mixed Composite chemical bonding agent is formed, adopting the addition method of adding; 4% of adding water, the above-mentioned percentages are percentages by weight.

Abstract

The invention discloses a special daub for fireproofing materials of a building carbon calcinator wall and a production method of the special daub. The special daub comprises the following components in weight percentage: 65% to 95% of composite high-aluminum chamotte powder composed of two kinds or more than two kinds of high-aluminum chamotte powder; 2% to 35% of composite chemical bonding agent composed of aluminum phosphate salt, sodium ascorbyl phosphate and water glass; 5.5% to 15% of composite nanometer micro powder composed of nanometer silicon oxide, silicon micro powder or silicon ash and aluminum micro powder; 0 to 30% of high-temperature expanding agent composed of silica powder or quartz powder; 0.5% to 5% of high-temperature agglutinant composed of a potassium base or sodium base feldspar powder; and 1%-5% accelerating agent composed of one kind or two kinds of cement and magnesia powder. The special daub is specially used for building a wall body with the fireproofing materials of a carbon calcinator, and is particularly used for building a wall body with fireproofing materials of a large-scale carbon calcinator; and the special daub has the advantages of very strong pertinence and higher bonding strength.

Description

technical field [0001] The invention relates to the field of refractory materials, in particular to a special cement used for masonry of carbon roasting furnace wall refractory materials, especially flue wall refractory bricks or flue wall prefabricated parts (blocks) and a production method thereof. Background technique [0002] The Chinese patent announced a high-temperature cement and its preparation method [Patent No.: ZL88106450] and a water-adjusted high-temperature cement and its use method [Patent No.: ZL95100912.5]. The invention time of these two high-temperature cement was 15 ~18 years ago, compared with the ordinary clay fire clay used at that time, the use effect was significantly improved. But from the perspective of long-term use practice, they still have two major problems: [0003] The first problem is that the pertinence is not strong, it is inevitable to lose sight of the other, and the expected use effect cannot be achieved. As described in the patent s...
