3 parts, 7.5 parts of silica, 7.5 parts of floating bead, 5 parts of binding agent.
One of preferred embodiment as the present invention, the bonding agent is the composite caking agent containing SiO2.
The invention also discloses a kind of production method of light fire brick, it is characterised in that comprises the following steps：
(1) flyash 60-90 parts, perlite 5-10 parts, wood chip 2-4 parts, silica 5-10 parts, floating bead 5-10 parts are added and stirred
Mix first dry-mixed 1-3 minutes in machine；
(2) and then bonding agent 4-6 parts and water are added, the content of the water of mechanical pressing is the 15-20% of batch mixing.Knock off shaping
The content of water be 20-30%；
(3) pressure dual-side is used after mixing, the aftershaping of slow pressurization；
(4) is placed one day after being molded, is then dried processing, elder generation's low temperature during drying, after be gradually heating to 100-120 DEG C
Fully dry；
(5) dried adobe burnt product in pushed bat kiln or tunnel cave.
One of preferred embodiment as the present invention, dry-mixed time optimal is 2 minutes in the step (1).
One of preferred embodiment as the present invention, the temperature in the step (4) are 110 DEG C.
One of preferred embodiment as the present invention, the pushed bat kiln or tunnel cave include following processing step：
(1) cold stage, i.e. room temperature~300 DEG C or so；This stage mainly excludes mechanical bond water and absorption in adobe
Water；Due to adobe, to enter stokehold once excessively dry, and flyash is poor material, therefore this stage can be rapidly heated；
(2) the oxygen stage, i.e., 300 DEG C~950 DEG C；More than 600 DEG C, charcoal element oxidation, to ensure charcoal element fully burning and gas
Discharge, this stage will slowly heat up and suitably be incubated, and otherwise can cause the black core of product；
(3) high temperature is burnt till the stage, i.e., 950 DEG C~1150 DEG C；This stage flyash produces liquid phase, in combination with the nothing in agent
Also there is liquid phase in sizing SiO2, and adobe is shunk, and produces bond strength；This stage programming rate should be slow.
The present invention compared with prior art the advantages of be：The present invention is green, makes full use of flyash to develop brick body not
Only total utilization of PCA provides a kind of new approach, and is a kind of compensation to the brick-making raw material of growing tension, has
Very big economic and social benefit.Inventive article appearance color is uniformly beautiful, and corner is neat, flawless and collapses mistake phenomenon, breaks
Covering weave is uniform, and clay light-weight brick national standard is above in terms of thermal conductivity factor and intensity.
