Abstract
The present invention relates to a kind of high calcium powder coal ash microporosity corebrick that is used for body of wall and roof heat insulation and preparation method thereof, this brick is the hollow casing of being made by high-calcium fly ass, pozzolana particle, saturated wet saw end and binding agent, and is filled with the core material of being made by pitch, vegetation chip or plastic foam fragment in it is hollow.Its making method is that with high-calcium fly ass, pozzolana particle, saturated wet saw end, binding agent and water carry out mixing and stirring; Vegetation chip or plastic foam fragment and pitch are heated back extrusion moulding respectively; Above-mentioned compound is sent into the moulding of vibrating in the mold, take out seasoning after the moulding.
That the present invention has is rational in infrastructure, technology is simple, cost is low, be easy to advantages such as construction, high insulating effect.
Description
The present invention relates to a kind of high calcium powder coal ash microporosity corebrick that is used for body of wall and roof heat insulation and preparation method thereof.
It is reported, the lagging material that is used for body of wall and roofing at present generally is loose fill type insulant (pearlstone, expanded vermiculite, sawdust and rice husk etc.) or loose fill type insulant goods, promptly the goods of different shape are made in the loose fill type insulant gluing together with cement, pitch, water glass etc., or with packed loose fill type insulant of plastics etc.Above-mentioned lagging material ubiquity has the inconvenience construction, heat insulation effect is poor, weak points such as intensity is low, in order to develop flyash, in recent years the someone developed " naturally-cured powdered coal ash brick " that be used for masonry panel made with flyash, sandstone, slag, slag, cement, lime, gypsum etc. (publication number is: 1046149A) and " the two hollow bricks of flyash non-bearing " that are used to be incubated though this brick is both economical, heat-insulating property is poor.
The objective of the invention is in order to overcome above-mentioned deficiency, provide a kind of rational in infrastructure, cost is low, be easy to the construction, high insulating effect, simple high calcium powder coal ash microporosity corebrick of manufacture craft and preparation method thereof.
Technical solution of the present invention is, in order to reduce cost, improve heat insulation effect and intensity, adopt high-calcium fly ass, pozzolana particle, saturated temperature sawdust and binding agent are made hollow casing, and are filled with the core material of being made by pitch and vegetation chip or plastic foam fragment in it is hollow.Its making method is as follows: high-calcium fly ass, pozzolana particle, saturated wet saw end, binding agent and water are carried out mixing and stirring.The weight percent at its high-calcium fly ass, pozzolana particle, saturated wet saw end is 40-65%: 58-32%: 2-3%, and water and binding agent account for the 5-15% and the 15-25% of above-mentioned compound weight respectively; Pitch and vegetation chip or plastic foam fragment are heated back extrusion moulding respectively.The weight ratio of its pitch and vegetation chip is 1: 5-7.The bituminous Heating temperature is 180-200 ℃, and the vegetation chip stirs baking under 80-100 ℃ condition, and moisture content is evaporated fully, replaces the vegetation chip also can toast as adopting the plastic foam fragment; Above-mentioned compound is sent into the moulding of vibrating in the mold, take out seasoning after the moulding.More than said vegetation chip be straw or rice husk or sawdust or wood shavings.Said binding agent is polyvinyl formal or Vinyl Acetate Copolymer.Said plastic foam fragment is polyvinyl chloride or polystyrene tailing.Said pitch is coal-tar pitch or petroleum pitch.
The micro molding process of this brick is, the one, and brick makes the water evaporates in the saturated wet saw end cause that the sawdust retraction volume dwindles and forms micro-pore in the process of seasoning.The 2nd, pozzolana particle itself just has countless micropores, for above-mentioned reasons, make the enclosure structure of high-calcium fly ass corebrick that variation take place, change the state that does not have contact between the particle each other, formed the porous three-dimensional grid structure that overlaps with high-calcium fly ass, binding agent, pozzolana particle, sawdust.
The present invention compared with the prior art, made the hollow casing of micropore corebrick owing to adopt high-calcium fly ass, pozzolana particle, vegetation chip and binding agent, and in it is hollow, be filled with the core material of making by pitch, vegetation chip or plastic foam fragment, therefore it is not only rational in infrastructure, cost is low, and heat insulation effect and intensity, (intensity reaches more than the 5MPa) have been improved effectively.In addition, the making method of this brick is also fairly simple.
Describe several specific embodiment of the present invention in detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of high calcium powder coal ash microporosity corebrick.
Fig. 2 is the making processes figure of high calcium powder coal ash microporosity corebrick.
Referring to Fig. 1, high calcium powder coal ash microporosity corebrick is the porous hollow shell 1 made by high-calcium fly ass, pozzolana particle, sawdust and polyvinyl formal and is made of the core material 2 that coal-tar pitch, rice husk are made.Its making method is (referring to Fig. 2), with 560 kilograms high-calcium fly asses, 798 kilograms pozzolana particle, 42 kilograms saturated wet saw end, 70 kilograms water, 210 kilograms polyvinyl formal drops in the stirrer and mixes, and puts into mold on the rotation diagram dish by hopper then.The weight percent at its high-calcium fly ass, pozzolana particle, saturated wet saw end is 40%: 57%: 3%.Water and polyvinyl formal account for 5% and 15% of above-mentioned compound weight respectively.Coal-tar pitch put in the heating kettle heat, be heated to 180 ℃, rice husk is put in the heating kettle, under 80-100 ℃ condition, stir baking, its moisture content is evaporated fully, then the coal-tar pitch of fusing and the rice husk after the oven dry are sent into by 1: 7 weight ratio and carried out extrusion in the extrusion machine, the compound that squeezes out enters in the mold on the rotating-disk.The mold that raw material is housed is by the shaking table moulding of vibrating, and takes out to be put into by artificial form removal after the moulding of vibrating and transports warehouse-in on the baby track car and carry out seasoning.
Embodiment 2
