Abstract
The invention discloses a shale compound sintered brick. The brick is made from the following raw materials with weight percentages: 30-98% of shale, 0-40% of slag and 2-50% of light aggregate. The production technology comprises the following steps: the shale is crushed, the crushed shale is evenly mixed with the light aggregate, or the crushed shale is evenly mixed with the slag and the light aggregate to obtain a mixture; the mixture obtained in the step two is added with water and evenly mixed to obtain adobe stock, the water accounts for 5-30% of the weight of the mixture; the adobe stock obtained in the step three is made into green brick; the green brick is dried; the dried green brick is piled and sintered in a kiln. The sintered brick leaves a large amount of air holes after the brick body is sintered, the air holes prevent heat bridges from forming, therefore, the brick has good thermal insulation property and the specific weight of the brick body is greatly reduced. The sintered brick can be used for making bearing and non-bearing walls.
Description
Technical field
The present invention relates to a kind of shale composite sintering brick and production technique thereof.
Background technology
Shale composite sintering brick is used widely in existing material of construction, but this shale composite sintering brick generally all is to be mixed and made into shale and waste residue, it can utilize the fluid-tight characteristics of shale to make the brick good waterproof performance of firing and waste residue is utilized reach the fundamental property of building brick, its heat-insulating property mainly realizes by on the brick body hole being set, and therefore inevitably exists heat bridge to make its heat-insulating property limited.
Summary of the invention
The object of the present invention is to provide a kind of shale composite sintering brick and production technique thereof that can effectively improve heat preservation and insulation.
This shale composite sintering brick provided by the invention is made by following raw materials by weight percent:
Shale 30-98, waste residue 0-40, light-weight aggregate 2-50.
Above-mentioned light-weight aggregate comprises one or more in glass bead, expansionization perlite, expanded vermiculite, float stone, haydite, the granular polystyrene.
Above-mentioned waste residue comprises: one or more in metallurgical slag, slag, flyash, red mud, the building waste
The production technique of above-mentioned shale composite sintering brick provided by the invention comprises the steps:
1. pulverize shale and/or waste residue;
2. shale and light-weight aggregate after will pulverizing stir, and shale after perhaps will pulverizing and waste residue and light-weight aggregate stir and obtain compound;
3. the compound that step 2 is obtained adds entry and stirs and obtain the adobe material, and the weight of water accounts for the 5-30% of described compound weight;
4. the adobe material that step 3 is obtained is pressed into adobe;
5. with brick blank drying;
Adobe piling after the oven dry, go into klining knot.
The raw material of vitrified brick of the present invention can leave a large amount of pores owing to adopted light-weight aggregate behind brick body sintering, these pores will be blocked the formation of heat bridge, thereby make brick that good thermal and insulating performance be arranged, and brick body proportion is also reduced greatly.Vitrified brick of the present invention can be suitable for making load-bearing and non-bearing wall body.
Embodiment
Shale composite sintering brick of the present invention is to be that the shale of 30-98, the waste residue of 0-40, the light-weight aggregate of 2-50 are made by weight percent; wherein light-weight aggregate comprises one or more in glass bead, expansionization perlite, expanded vermiculite, float stone, haydite, the granular polystyrene, and waste residue comprises: one or more in metallurgical slag, slag, flyash, red mud, the building waste.According to raw material of the present invention and production technique, the contriver has done following enforcement.
Embodiment one: get weight ratio and be 90% shale and 10% glass bead, produce by following technology:
1. shale powder is broken to particle diameter all less than 0.2mm;
2. shale of Fen Suiing and the glass bead resulting mixture that stirs;
3. add entry and be stirred into the adobe material in the mixture that step 2 obtains, wherein water accounts for 15% of mixture weight.
4. the adobe material that step 3 is obtained is pressed into adobe;
5. with brick blank drying;
Adobe piling after the oven dry, go into klining knot.Sintering temperature is 950 ℃.
7. product kiln discharge
Product performance energy behind the kiln discharge:
Density: 1.22g/cm
3
Ultimate compression strength: 21.3MPa
Thermal conductivity: 0.23W/m.K
The thermal conductivity of vitrified brick of the present invention is very low as can be seen from the performance of product, its thermal and insulating performance is very good, and the low quality of density is light, the ultimate compression strength height, therefore as bearing wall still be non-load bearing wall all be very suitable, other embodiment has also fully confirmed this point.
Other embodiment sees Table one, and their production craft step is identical (also will pulverize if waste residue is arranged in the component of these embodiments) but component is different with processing parameter:
