Abstract
A micropore hollow brick is disclosed. The micropore hollow brick comprises a clay brick main body and micropores formed after straw stalk is combusted. The straw stalk is mixed in the clay brick main body or on surfaces of the clay brick main body. The micropore hollow brick is prepared by selecting materials, mixing, molding a green brick, firing, drawing, and the like. The micropore hollow brick has a sound insulation effect and is simple in manufacturing process.
Description
Technical field
The invention belongs to building materials field, be specifically related to a kind of microporous hollow brick and preparation method thereof.
Background technology
Loam brick is artificial small-sized bulk for building, also by title clinker brick.Solid clay brick is one of the most ancient in the world constructional materials, and from Shaanxi Qin Shihuang Tomb to Ming Qing Great Wall, Beijing, it has passed on Chinese nation's building civilized history of several thousand.So far, it is still the constructional materials that compatriots' inner feelings is liked.Divide by hole ratio: (hole ratio is equal to or greater than 25%, and the size in hole is little and the brick that quantity is many, and be usually used in weight bearing area, strength grade is higher for solid brick (being less than the brick of 25% without hole or hole), porous brick.Hollow brick (hole ratio is equal to or greater than 40%, and the size in hole is large and brick that quantity is few, and be usually used in non-weight bearing area, strength grade is on the low side).
Loam brick with clay (comprising the powder such as shale, gangue) for primary raw material, form loam brick fall throwing face through pug process, shaping, dry and roasting, China has formulated square and microscler brick successively in the Spring and Autumn and the Warring States Periods, the technology of Qin Han dynasty brickmaking and production scale, quality and pattern variety all take shape, and be referred in the world " Qin brick and Han tile ".Common brick is of a size of 240 millimeters × 115 millimeters × 53 millimeters, by compressive strength (newton/square millimeter, N/mm2) size is divided into these 6 strength grades of MU30, MU25, MU20, MU15, MU10, MU7.5, loam brick is gathered materials on the spot, low price, durable in use, also have the advantages such as fire prevention, heat insulation, sound insulation, the moisture absorption, use extensively in civil construction project, useless queen closer also can do concrete gathering materials.For improve unselected clay fragment of brick little, from great, that consumption soil is many shortcoming, the future development of forward lightweight, high strength, hollow, bulk.Sand lime brick with the lime of proper proportion and quartz sand, sand or packsand, through levigate, add water mix and stir, semidry method is compressing and form through steam press maintenance.Fly ash brick is primary raw material with flyash, mixes the cementitious materials such as colliery powder or clay, forms, can make full use of industrial residue through batching, shaping, dry and roasting, saving fuel.
Summary of the invention
The technical problem to be solved in the present invention is loam brick of the prior art is solid construction, does not have the defect of soundproof effect in order to solve solid brick, provides a kind of microporous hollow brick and preparation method thereof, realizes the object of sound insulation.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of microporous hollow brick, the micropore formed after obstructing burning by loam brick body and straw forms, and described straw stalk is blended in loam brick body interior or surface.
The preparation method of microporous hollow brick, comprises the following steps: select materials, mixing; Green brick forming; Fire; Kiln discharge.
Implement a kind of microporous hollow brick of the present invention and preparation method thereof and there is following beneficial effect: because straw stalk is mixed in clay; when firing, straw stalk fires due to high temperature and incinerates; in loam brick, just define micropore, achieve the sound insulation function of loam brick, and preparation technology is simple.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, technical scheme of the present invention is further illustrated:
Fig. 1 is the structural representation of a kind of microporous hollow brick of the present invention.
Detailed description of the invention
Embodiment one
A kind of microporous hollow brick, the micropore 2 formed after obstructing burning by loam brick body 1 and straw forms, and described straw stalk is blended in loam brick body interior or surface.
The preparation method of microporous hollow brick comprises the following steps: select materials, and clay and straw obstruct gets the raw materials ready by 100:5; Mixing, is mixed in clay by straw stalk; Green brick forming; Fire, in sintering procedure, straw stalk fires due to high temperature and incinerates, in loam brick, form micropore; Kiln discharge, the loam brick that inner or surface has micropore is formed, and the hollow brick internal structure change fired in this ratio is little, has stronger bearing capacity, can be used as exterior wall and can also be used as interior wall.
Embodiment two
A kind of microporous hollow brick, the micropore 2 formed after obstructing burning by loam brick body 1 and straw forms, and described straw stalk is blended in loam brick body interior or surface.
The preparation method of microporous hollow brick comprises the following steps: select materials, and clay and straw obstruct gets the raw materials ready by 100:10; Mixing, is mixed in clay by straw stalk; Green brick forming; Fire, in sintering procedure, straw stalk fires due to high temperature and incinerates, in loam brick, form micropore; Kiln discharge, the loam brick that inner or surface has micropore is formed, the hollow brick fired in this ratio, and internal capillary is many, and bearing capacity is not enough, can only be used as interior wall and use.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite not departing from structure of the present invention; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
Claims (2)
