Abstract

The invention relates to an environmental protective brick. The weight percent of the raw material components is 40-60 percent of goal gangue, 30-50 percent of shale and 3-20 percent of sludge. The making method of the environmental protective brick consists of the following steps: firstly, raw materials preparation: the coal gangue and the shale are evenly mixed for using after being grinded; secondly, material aging treatment; thirdly, forming: forming a green brick through an extruder; fourthly, drying: drying the green brick at 100-110 DEG C; fifthly, roasting: roasting the green brick at 1030-1050 DEG C, which is cooled then to obtain the environmental protective brick. The invention has the advantage of fully utilizing industrial and civil wastes which are abandoned and are harmful to the environment to produce construction-used environmental bricks according with requirements. The raw materials have the advantages of extensive sources and low cost. No coal is needed during the brick firing. Both the energy consumption can be lowered, and the cultivated lands can be protected.

Description

Environmental protection brick and manufacture method thereof

Technical field

The present invention relates to a kind of material of construction, particularly a kind of environmental protection brick and manufacture method thereof of utilizing the waste material preparation.

Background technology

Existing brick adopts the clay method for cooking to make mostly, therefore can destroy a large amount of farmlands, and the energy consumption height, has belonged to the stage of eliminating.

The disclosed a kind of production method of sludge baked brick that utilizes of Chinese patent literature CN1413939 A, it adopts mud and shale is raw material, the content of mud is generally 50～5%, commonly used is 50～30%, and the shale powder is its surplus, general particle diameter≤0.5mm, commonly used≤0.3mm, conventional base roasting.Its raw material that adopts is because the amount of mud is bigger, and the quality of mud is subject to the variation of environment, and the source is also unstable, so its cohesiveness and insufficient strength, and the quality of product is also unstable.

Summary of the invention

Technical problem to be solved by this invention is to overcome the above-mentioned deficiency of prior art and a kind of environmental protection brick is provided, and makes its better quality, and energy consumption is lower, and raw material is more extensive.

The present invention solves the problems of the technologies described above the technical scheme that is adopted:

The environmental protection brick, described raw material consists of weight %: coal gangue 40-60 shale 30-50, mud 3-20.

The manufacture method of above-mentioned environmental protection brick, form by following steps:

(1), feedstock production: coal gangue, shale pulverizing back and mud mixing and stirring is stand-by;

(2), the raw material ageing is handled:

(3), moulding: with forcing machine moulding adobe;

(4), drying: adobe is in temperature 100-110 ℃ drying;

(5), roasting: adobe is in temperature 1030-1050 ℃ roasting, after the cooling promptly.

Compared with prior art, the invention has the advantages that: make full use of environmentally harmful industry of depleted and civilian refuse and make the satisfactory environmental protection brick that is used to build, its raw material sources are extensive; cost is low; bake bricks without coal, can cut down the consumption of energy, can protect farmland again.

Embodiment

Below in conjunction with embodiment the present invention is described in further detail.

Embodiment 1:

The environmental protection brick, adopt following proportioning: coal gangue 60 shale 37 mud 3% make by the following method:

(1), feedstock production: coal gangue and shale raw material respectively through Mechanical Crushing, are sieved, shale and the coal gangue powder of particle diameter 0.3mm, shale, coal gangue and mud are mixed by proportioning and are made into compound;

(2), the raw material ageing is handled: the dried even water humidifying that is mixed, ageing 24 hours;

(3), moulding: with the forcing machine moulding adobe of the raw material after the ageing;

(4), drying: with the adobe seasoning at room temperature of forming 24 hours, in the time of 105 ℃ dry 8 hours then;

(5), roasting: go into the kiln roasting, roasting condition is: by heat-up rate is 150 ℃/hour, and maturing temperature is 1030-1050 ℃, and roasting was incubated 2 hours after 12 hours, and cooling promptly gets product.
