Technical field
It the utility model is related to thermal insulation fire-resistant article technology, more particularly to a kind of refractory brick.
Background technology
Refractory brick abbreviation firebrick.For the refractory material with definite shape and size.Can to divide by process of preparing
Be divided into be fired into bricks, unburned brick, fused cast refractories (molten-cast brick), refratory insulating brick；It can be divided into standard size brick, common by shape and size
Brick, Idiotype turn etc..It can be used as building kiln and the high temperature construction material and structural material of various Thermal Equipments, and at high temperature
It is amenable to various physicochemical changes and mechanism.
Refractory brick is insulation material more commonly used in high-temperature firing stove, and common refractory brick is mostly just in the market
Cuboid, the cube structure of rule.The class formation can not meet the fire resisting demand for special shape requirement.Especially kiln,
The chimney of the occasions such as tile stove, or charging aperture, observation panel etc.；The class formation can not meet the fire resisting for special shape requirement
Demand.Especially flow through pipeline of hot fluid etc..And such pipeline generally need to additionally set cooling system, structure is more multiple
Miscellaneous, manufacturing cost is higher, maintenance difficult.
Utility model content
The utility model purpose is to provide a kind of refractory brick, have the porosity is high, bulk density is small, fire resisting effect is good,

A kind of refractory brick, including refractory brick body, the refractory brick body are column construction, and the refractory brick body is from inside to outside
Including the first flame retardant coating, vacuum heat-insulating layer, the second flame retardant coating and heat-insulation layer；Described the first flame retardant coating, vacuum insulation panel,
Bonded and formed by lightweight clay between four layers of two flame retardant coatings and heat-insulation layer；The first described flame retardant coating is provided with multiple from interior
Outwards run through the through hole of the refractory brick body.
Further, it is also coated with flame-retardant coating layer on the first described flame retardant coating inner surface.
Further, the first described flame retardant coating is formed for high-alumina lightening refractory material.
Further, described vacuum heat-insulating layer is by the inorganic fibre mat after the inorganic fibre mat of several stackings and stacking
Integral surface is covered with aluminium foil film and vacuumized and forms.
Further, the inorganic fibre mat includes glass fibre, ultra-fine fibre glass and ultra-fine rock wool.
Further, second flame retardant coating is that high-alumina lightening refractory material is formed so that refractory brick have the porosity it is high,
Bulk density is small, fire resisting effect is good, high mechanical strength, thermal conductivity factor are small, service life length.
Further, the heat-insulation layer be lightweight air hardening refractory castable form so that refractory brick have higher-strength,
It is strong compared with low thermal conductivity, smaller Linear change rate, heat insulation effect.
The beneficial effects of the utility model are：
1st, the refractory brick body design is applied in kiln into column construction, it is only necessary to which 3 to 4 pieces with regard to that can surround a stove
Body, it is easy to operate, not time-consuming it is effortless, quick, cost is low.
2nd, this refractory brick uses double-deck flame retardant coating, and than existing stove, refractoriness provides several times, and in two layers of flame retardant coating
Between thermal insulation layer is set so that the second flame retardant coating fire resistance is not influenceed by the first flame retardant coating, and thermal insulation layer also has fire resisting
Property.
3rd, being bonded between every layer and formed by lightweight clay so that body of heater keeps preferable globality and air-tightness for a long time,
Also so that there is body of heater elevated temperature strength height, corrosion resistance, resistance to high velocity air to wash away.
4th, the first flame retardant coating is provided with multiple through holes for running through the refractory brick body from inside to outside, can be passed through in the through hole
Cooling agent, such as water, the temperature of hot fluid is reduced, play a part of cooling.
5th, fireproof coating is scribbled in the first flame retardant coating inner surface so that the fire resistance of first layer flame retardant coating, which has been got back, to be carried
It is high.
