Abstract
The invention discloses a high-wind speed resistance capacity wear-resistant fiber surface coating. The high-wind speed resistance capacity wear-resistant fiber surface coating is characterized by mainly comprising the following raw materials in percentage by mass: 15 to 20 percent of alumina particles with the particle diameter of 4 to 20 mu m, 50 to 60 percent of mullite particles with the particle diameter of 0.1 to 1mm, 25 to 35 percent of aluminum sol with the content of 5 to 10 percent, and 0.2 to 0.5 percent of adhesive. By improving a process and a formula, the wind speed resistance capacity of the surface coating is improved to 60 meters/second, and the surface coating can be cured when being dried at the temperature of 105 DEG C; and the high-wind speed resistance capacity wear-resistant fiber surface coating is greatly superior to common surface coatings, and the performance of the high-wind speed resistance capacity wear-resistant fiber surface coating is greatly improved.
Description
Technical field
the present invention relates to refractory fibre production field, especially a kind of high resistance wind speed fiber surface coating that resistance to wears.
Background technology
at present, the refractory materials application aspect of various kilns, is widely used ceramic fiber block as refractory insulating layer at home, and ceramic fiber possesses special good performance, and its shrinking percentage is little, and thermal conductivity is low, good heat insulating.But under the Special use environment of high wind speed (60 meter per second), as in some kilns of high wind speed, because the quality of ceramic fiber own is softer, surface fiber will be dispelled and fly by high wind speed, can cause the environment in stove deteriorated so on the one hand, also can make on the one hand thermal insulation layer loosening, erosion gradually, insulation layer thickness reduces, and causes the decline of the heat-insulating and energy-saving effect in overall kiln.For addressing this problem, on domestic market, just there is the topcoating of refractory fibre.It,, take refractory fibre and refractory powder as main component, adds peptizer, after chunk surface spraying, can form very hard layer protective layer, has certain wind resistance speed, erosion-resisting performance.But the at present domestic topcoating generally using, its Performance Ratio of resistance to wind speed is more limited, is approximately 30 meter per second left and right, such topcoating, while using in passivation stove and AP stove, because wind speed reaches 60 meter per seconds, so still easily dispelled the loosening loss that causes thermal insulation layer.To this, have client to adopt refractory brick to carry out substitution tables coating materials, but due to refractory brick price be topcoating 2-3 doubly, so can not generally solve cheaply above problem.
therefore, in the urgent need to researching and developing a kind of topcoating that can tolerate high wind speed, guarantee the lasting result of use of kiln inner thermal insulating layer under high wind speed, improve the service efficiency of lagging material, and solve the puzzlement in client's use cost.
Summary of the invention
the present invention seeks to: the invention provides one easy to use, moulding onset effect is fast the above wind speed of the anti-60m/s of energy, erosion-resisting refractory ceramic fibre topcoating.Be specially adapted to, in the continuous furnace, forge furnace, forging furnace of metallurgy industry, be conducive to protect the thermal insulation layer of ceramic fiber, improve furnace service life.
technical scheme of the present invention is:
a kind of high resistance wind speed fiber surface coating that resistance to wears, it is characterized in that, mainly by the composition of raw materials of following quality percentage composition, formed: the alumina particle 15%-20% of particle diameter 4-20um, the mullite particle 50%-60% of particle diameter 0.1mm-1mm, the aluminium colloidal sol 25%-35% of content 5%-10%, caking agent 0.2%-0.5%.
product chemical composition (after dry), Al2O3 content 70%-80%, Al2O3+SiO2 content > 99%.
further, described binding agent is polyacrylamide
product of the present invention drops into the technical process manufactures such as mix and blend by batching-blending in of fibers-particle stirring-colloidal sol stirring-additive.As the fire-resistant powder of main material, hardness that will consideration itself, also will consider resistivity against fire, has used mullite particle and the alumina particle of several different-grain diameters.
meanwhile, as dispersion solvent, we have adopted the main chemical compositions solvent similar with powder, make it dispersed better in whole solvent, are not easy to occur sedimentation and the caking that becomes dry.
advantage of the present invention is:
the high wind resistance wear-resistant surfaces of the present invention coating, adopts special formulation ratio, and use temperature is the heating permanent line velocity of variation (1400 ℃ × 24h)≤0.5% under 1400 degree, at 105 ℃, is dried the rear intensity that just can reach anti-60 meter per second wind speed.Product of the present invention, by process improving and formula improvement, is increased to 60 meter per seconds by the wind resistance speed ability of topcoating, and dry plastic under 105 degree, is far superior to common topcoating, is a very large lifting in performance.
