Preparation method of the present invention is:
(1), broken raw material, respectively clay, fine coal charcoal, vegetable fibre are carried out fragmentation, vegetable fibre is generally the straw or the wood chip of paddy and wheat, corn etc., the length after the fragmentation is 3mm-5mm,
(2), batch mixes, weight ratio by clay, fine coal charcoal, vegetable fibre is prepared burden and is stirred, earlier clay, fine coal charcoal, vegetable fibre are delivered in the roll crusher broken 3-5 minute, be transported in the biaxial rneader again, this moment is for improving the quality of building block (brick), can add an amount of paper pulp, the concentration of paper pulp is 3-5%, stirs after 5-10 minute, is delivered in the roll crusher and stirs, time is 3-5 minute
(3), compression moulding, utilize single-lead-screw extruding briquetting machine to be pressed into holllow building block (brick) base substrate, building block (brick) base substrate hole ratio is at 20-60%,
(4), cool base, adopt the method for the cool base of nature, also can adopt heating or add method such as wind and carry out cool base,
(5), sintering, adopt common clay brick sintering method to carry out sintering building block (brick) base substrate and get final product.
Clay among the present invention can adopt shale to substitute, and the fine coal charcoal can adopt spoil to substitute.
Among the present invention owing to be hollow sintered building block (brick), saved effectively raw material usage quantity, reduced cool base, sintering time, reduced the required energy of sintering, reduced the deadweight of building, cost reduction, the shock resistance of building are improved, holllow building block (brick) compares with solid block (brick) that also to have a thermal conductivity low in addition, and soundproof effect is good, good heat insulating, advantages such as Heat stability is good.
Added the fine coal charcoal among the present invention, the fine coal charcoal is the waste in industry, the life, its surface-area is big after break process, help activeconstituents and participate in reaction, the utilization of slurry reaction hydration heat is abundant, the hydration heat of slip is evenly distributed, and the base substrate sclerosis of making is obviously accelerated, and also makes building block (brick) intensity, splitting resistance among the present invention reach advantages such as Heat stability is good well.
Be added with vegetable fibre among the present invention, increased the hole ratio of building block (brick), alleviated the weight of building block (brick), reduced at the required energy of sintering process, also make the water-intake rate of building block (brick) little in addition, drying shrinkage shape do not occur, splitting resistance is good, thermal resistance coefficient ren is big, insulation, sound-proofing properties are good.
Added an amount of paper pulp among the present invention,, reduced the usage quantity of clay to increase the plasticity of batching.
Description of drawings
Accompanying drawing is the structural representation of building block among the present invention (brick).
Embodiment
Below the present invention is further described:
A kind of light thermal-insulation sintered building block (brick) is to be the hollow brick that raw material is made by clay, fine coal charcoal, vegetable fibre, and wherein, the weight ratio of described each composition is:
Clay: 30%-60% fine coal charcoal: 35%-50% vegetable fibre: 0,73%-3,56%, surplus is a water.
The usage quantity of each moiety can be with reference to following table:
| Clay | The fine coal charcoal | Vegetable fibre | |
| Prescription scheme one | 48％ | 49％ | 3％ |
| Prescription scheme two | 60％ | 39％ | 1％ |
| Prescription scheme three | 35％ | 50％ | 4％ |
| Prescription scheme four | 50％ | 47％ | 3％ |
| Prescription scheme five | 50％ | 35％ | 4％ |
