Abstract

The invention provides a slag wall brick and a preparation method of the slag wall brick, and relates to a preparation process technology of the wall brick. Through mixing a modifying plasticizer and an enhancing curing agent with slag uniformly, compression resistant bricks are prepared through cutting with a brick making machine or hollow wall-filling blocks are prepared by compression molding. Due to the adoption of the method, the land source can be saved; the bricks are unfired, so that the energy is saved; the bricks can be manufactured easily and fast; the pollution and emission are avoided, so that the preparation method is environment-friendly; the compressive strength of the brick provided by the invention is higher than that of a sintered brick; the brick is water-proof, acid and base resistant and aging resistant; the utilization of was materials is realized, and the cost is low, so that the brick is the replacement of a traditional sintered brick, and is an effective measure for solving the slag accumulation problem.

Description

A kind of slag wall-building brick and preparation method thereof

Technical field

The present invention relates to the fabricating technology of wall-building brick, relate in particular to a kind of slag wall-building brick and preparation method thereof.

Background technology

Along with the exploitation expansion of metallic ore industry, ore quantum of output is increasing, and slag storage capacity is also in company with more and more, and the development to Metal mining that increases of slag brings difficulty, the fast development of puzzlement Mineral industry.It is unsatisfactory that current metallic ore cleans the slag cyclic utilization rate of discharging, and by storing, piles up, and fills out hole, and it is to occupy cultivated land on the one hand that hole is filled out in accumulation, affects grain quantum of output, dwindles acreage under cultivation.When rainy, easily with rainwater, flow into farmland, lake on the other hand, cultivate to periphery peasant and make troubles, flow into Gou Tang lake, also can polluted water resources, make clear water become muddy water, aquaculture is affected by it, be unfavorable for the development of ecotope, greatly develop Metal mining, just must rationally solve the flow direction of slag, recycle slag soil just must hold water, make it be converted to valuable wealth, turn waste into wealth, for emerging social construction used.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of slag mound that can solve and puts land occupation, and a difficult problem for influence ecological environment is also for building construction increases building material, reduces building cost and a kind of slag wall-building brick and the using method thereof developed.

Technical problem to be solved by this invention realizes by the following technical solutions:

A slag wall-building brick, is characterized in that, adopts modification fluidizer and strengthen solidifying agent to mix with slag, makes resistance to compression brick or compression moulding make hollow and fill out wall building block through brickmaking machine cut formation of lots, and it is to be made by the raw material of following weight proportion:

Modification fluidizer 60-150 part

Strengthen solidifying agent 1-2.5 part

Slag 850-940 part.

Described modification fluidizer is by 97% part of silicate cement, 1.5% part, magnesium sulfate, 1.5% part of mixture mixing of boron.

Described enhancing solidifying agent is to be 0.3% part of mixture mixing of borax by 90% part of polyvinyl alcohol, 6% part, flour, 4% part of isocyanic ester, linking agent.

4, a kind of prepare slag wall-building brick method, preparation process is as follows:

A, take each raw material by weight;

B, slag is put into and pulverized in mixing machine by proportioning deal, modification being plastified to drug puts into and pulverizes in mixing machine by proportioning deal again, pulverizing powdered mixes, to solidify again and strengthen drug by proportioning deal, depending on humidity, add water and be spilled in right amount and pulverize in mixing machine material, mix, be transported to excision forming in brick press, dry to obtain finished product slag wall-building brick, or be transported to compression moulding in pressure brickmaking and make slag Hollow brick.

(1) below by weight

900 parts, slag is put into and pulverized in mixing machine, then by 98 parts of inputs of modification fluidizer, start is pulverized and is mixed, mass dryness fraction eighty per cant dry more than, as appropriate lower than the eighty per cant dry siccative that adds, siccative is calcium bentonite.

(2) by polyvinyl alcohol 90% umber, join in the water of 10 times, be warming up to 95 degree, after particle dissolves completely, be cooled to 60 degree and add 0.25% part of borax, stir and slowly add 6% part of modified wheat flour, be warming up to 90 degree, (object improves the waterproof weather resistance of polyvinyl alcohol to add 4% part of isocyanide ester, flour and borax had carried out water-repellent modifiedly to polyvinyl alcohol above, and isocyanic ester can not add, and 95 degree heat up, high-speed stirring, drop to normal temperature: strengthen solidifying agent.Strengthen 2 parts, solidifying agent (solid content), depending on the humidity of slag, add water appropriate, put into pulverize in stirrer slag and be uniformly mixed, be transported in brick press, excision forming makes slag wall-building brick, also can be transported in pressure brick press the molded slag Hollow brick that obtains of the pressure-off of shaking.

Beneficial effect of the present invention is: can economize the land resource, energy-conservation unburned, manufacture simple and quick, without dirty without row's environmental protection; Ultimate compression strength is higher than vitrified brick, waterproof, and antiacid alkali, ageing-resistant; Utilization of waste material, cost is low, is the substitute of conventional sintering brick, is also to solve slag to pile up difficult effective measure.

Embodiment

For technique means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with the example of embodiment, the present invention is described in further details.

Embodiment mono-

850 parts, slag, 150 parts of modification fluidizers, put into and pulverize in mixing machine, are crushed into powder and mix, to strengthen again solidifying agent 1 part (solid content) and look humidity, add water appropriate, put in slag mix, mix, be transported in brick press mould, excision forming makes slag wall-building brick, dries, and gets product.

Embodiment bis-

By 900 parts, slag, 98 parts of modification fluidizers, put into and pulverize in mixing machine, be crushed into powder and mix, to solidify and strengthen drug 2 parts (solid content) depending on humidity, to add water appropriate, and put in pan mill and mix, humidity remains on eighty per cant dry left and right, be transported to compression moulding in pressure brick press, dry to obtain slag Hollow brick finished product.
