Abstract
The invention discloses a powerful binder for a refractory brick, and relates to a binder in the field of refractory materials. The powerful binder consists of the following components in parts by weight: 5-10 parts of phenolic aldehyde varnish, 5-20 parts of phenolic resin, 2-5 parts of hexamethylenetetramine, 40-65 parts of magnesia powder, 5-10 parts of clay powder and 10-20 parts of wetting agent. The powerful binder for the refractory brick disclosed by the invention has good cohesiveness with the refractory brick as well as perfect cohesive force; meanwhile, the settling time is short, and the construction time can be remarkably saved.
Description
Technical field
The present invention relates to a kind of binding agent of fire resisting material field, be specially a kind of Powerful binder for refractory brick.
Background technology
Magnesia carbon brick is a kind of conventional refractory brick, has that refractoriness is high, anti-slag invades the advantages such as performance is good, resistance to heat shocks is strong, as furnace lining material widespread use on all kinds of steel melting furnace.Magnesia carbon brick is produced and is adopted compression moulding, the pressure that the shaping needs of big brick are larger more, therefore shaping more difficult, usually builds by laying bricks or stones between single magnesia carbon brick with the masonry that binding agent carries out boning to be formed bulk.The environment used due to magnesia carbon brick is usually harsher, therefore requires higher equally for the cohesive strength of binding agent, refractoriness and the performance such as anti-slag, resistance to fouling.Existing high-temperature agglomerant is mainly the organic binder bond of silicates, phosphoric acid salt and Sulfates mineral binder bond and resene, and mineral-type binding agent has good thermotolerance and antioxidant property, but its viscosifying power is poor, and workability is bad.And general organic resin class binding agent has excellent adhesive property at normal temperatures, but at high temperature viscosifying power sharply declines, and refractory brick is all applied in high temperature environments usually, this just requires that its binding agent used must bear high temperature, and still there is higher cohesive force and good anti-erosion, thermal shock resistance in high temperature environments, and existing high-temperature agglomerant is this requirement do not reached.
Summary of the invention
Object of the present invention is just to provide a kind of Powerful binder for refractory brick, for the bonding between the refractory brick such as magnesia carbon brick or other siliceous brick, high alumina brick, magnesia chrome brick, solves the existing general binding agent problem that cohesive strength is not high in hot environment.
To achieve these goals, technical scheme of the present invention is: a kind of Powerful binder for refractory brick, counts it by weight and consists of: phenolic varnish 5 ~ 10 parts, 5 ~ 20 parts, resol, hexamethylenetetramine 2 ~ 5 parts, magnesia powder 40 ~ 65 parts, clay powder 5 ~ 10 parts and wetting agent 10 ~ 20 parts.
Described wetting agent is ethanol or ethylene glycol.
The preparation method of described binding agent is: first phenolic varnish, resol, hexamethylenetetramine and wetting agent are undertaken mixing by described weight part, stir after add the magnesia powder of described weight part again and clay powder stirs.
Binding agent of the present invention can be used for the bonding of magnesia carbon brick, also can be used for the bonding between the refractory brick such as siliceous brick, high alumina brick, magnesia chrome brick.
Beneficial effect: the cohesiveness between binding agent of the present invention and refractory brick is good, has extremely strong cohesive force, and under its normal temperature and high temperature, the cohesive strength of self is all higher, and it is after 1600 DEG C of high temperature burn 3 hours after testing, and its folding strength can reach 40MPa.And binding agent of the present invention can in 15 ~ 20 minutes rapid solidification, dramatically saves on the time of construction.In addition, binding agent of the present invention also has good anti-erosion effect, in the bonding of magnesia carbon brick, is not vulnerable to the erosion of molten steel in steel melting furnace, not easily oozes steel phenomenon.Wherein, the present invention is using magnesium oxide and clay as the refractory powder of binding agent, magnesium oxide is as the main refractory aggregate of binding agent, there is good high thermal resistance and corrosion-resistant property, and be easy to make magnesia carbon brick or other refractory brick bonding, clay can improve the cohesive force of binding agent inside, improves the self-strength of binding agent.Phenolic varnish and resol have excellent high thermal resistance and cohesiveness, play main cohesive action, can make to be bonded together securely between refractory powder and refractory brick, ethanol or ethylene glycol can by refractory powder moistened surfaces, thus effectively bond with refractory brick under phenolic varnish and resol effect, also make each component of binding agent to mix equably simultaneously.Hexamethylenetetramine mainly plays sclerization, strengthens the cohesive strength of binding agent and improves the thermal shock resistance of binding agent.
