Abstract

The invention discloses a sintered water permeable brick with a smooth and mildew-proofing surface. The water permeable brick is prepared from the following raw materials in parts by weight: 40-43 parts of sludge of a sewage plant, 6-7 parts of rice husks, 4-5 parts of potassium feldspar powder, 5-6 parts of pulverized fuel ash, 3-4 parts of bamboo powder, 8-10 parts of activated pozzolana, 19-21 parts of fluorite tailings, 4-5 parts of noan-silicon carbide, 2-3 parts of sodium carboxymethyl cellulose and 3-4 parts of light magnesium oxide. According to the sintered water permeable brick, the fluorite tailings, palm fibers, nano-silicon carbide and other ingredients are added to serve as aggregate ingredients of a brick blank, so that the tensile strength and crack resistance of a brick body can be enhanced, and the porosity of the brick body is further improved; the bamboo powder added into the brick is turned into a bamboo charcoal ingredient by means of sintering, so that the water permeable brick has excellent antibacterial and mildew-proofing effect. The manufactured water permeable brick has an attractive appearance and smooth surface, and integrates strength, water permeability and corrosion resistance into a whole.

Description

The sintering brick permeable to water that a kind of any surface finish is not easily gone mouldy

Technical field

The present invention relates to building material technical field, particularly relate to the sintering brick permeable to water that a kind of any surface finish is not easily gone mouldy.

Background technology

Sponge city refers to that city as sponge, can have good " elasticity ", water suction when raining, retaining, infiltration, water purification, discharged by the water stored and be used when needing in conform change and reply natural disaster etc.In sponge Process of Urban Development, the systematicness of natural precipitation, surface water and groundwater should be planned as a whole, coordinate each links of water circulation use such as feedwater, draining, and consider its complicacy and chronicity.As everyone knows, road surface, existing urban street mostly adopts the fluid-tight material such as cement concrete, pitch, stone material, ceramic tile to lay and forms, and this hard surface is inadaptable trend of building sponge urban pavement.

Water-permeable brick has good water-permeable and performance of keeping humidity, can alleviate " city desertification " and " tropical island effect " problem that city is brought due to hard surface well, is conducive to keeping city water balance; Natural precipitation can be absorbed by water-permeable brick rapidly, and permeates the ground through earth's surface, in good time recharge of groundwater position; Water-permeable brick can be eliminated or reduce excess surface water, and while generation Benefit of Flood Preventation, numerous urban pollutant is not moved by flowing water and causes more large-area environmental pollution; After rainfall terminates, the moisture in water-permeable brick is discharged into again in air gradually, regulates earth's surface temperature and humidity, alleviates city " tropical island effect ", safeguard the earth's surface eubiosis; Water-permeable brick has sound-absorbing and antiskid function simultaneously, can improve security and the comfortableness of walking, absorbs vehicle and travels the noise produced, and creates quiet comfortable traffic environment.Pervious floor tile can be widely used in the laying on the road surfaces such as house, garden, park, square, walkway and light duty traffic highway, can produce good society, environment and ecologic effect.

For a long time, the sludge treatment of Sewage Plant is an environmental issue always.Sludge landfill fundamentally can not solve the pollution problem of mud to environment, and the cost that the regeneration of mud is recycled is very high, and therefore the recycling of mud is considered to most economical rational disposal options.Sewage plant sludge is except containing except a small amount of organic composition, and the inorganic componentss such as most of silicon-dioxide, aluminium sesquioxide, ferric oxide are similar with clay component, and cohesiveness is better, thus can make the raw material of the material of construction such as brick, cement clinker, haydite.For a long time, clay brick as the maximum most important materials for wall of building trade consumption, not only can damage farmland, a large amount of soil every year, and destroy ecotope always, so this is made building material, is a kind for the treatment of process of economical rationality.

Summary of the invention

The object of the invention is exactly the defect in order to make up prior art, provides the sintering brick permeable to water that a kind of any surface finish is not easily gone mouldy.

The present invention is achieved by the following technical solutions:

The sintering brick permeable to water that any surface finish is not easily gone mouldy, is made up of the raw material of following weight part: sewage plant sludge 40-43, rice husk 6-7, feldspar in powder 4-5, flyash 10-12, water glass 10-12, red mud 11-13, re-dispersible glue powder 3-4, monkey grass 5-6, bamboo powder 3-4, active pozzolans 8-10, fluorite tailings 19-21, nanometer silicon carbide 4-5, Xylo-Mucine 2-3, light magnesium oxide 3-4.

The sintering brick permeable to water that described a kind of any surface finish is not easily gone mouldy, be made up of following concrete steps:

(1) by sewage plant sludge seasoning, pulverization process crosses 200 mesh sieves, obtains mud powder stand-by; By the mud powder of half amount, rice husk, feldspar in powder mixing, add appropriate water, put into stirrer and stir into pug with the speed of 120 revs/min, controlling water content is 20%, then send into extruding pelletization in tablets press and obtain mud granule, controlling grain graininess is 10 orders;

(2) mud granule is put into loft drier, sinter to send in resistance furnace after the temperature drying of 100 DEG C, be warming up to 800 DEG C, be incubated 60 minutes, then continue to be warming up to 1100 DEG C, be incubated 60 minutes, obtain porous mud granule;

(3) monkey grass is shredded mix with fluorite tailings, put into pulverizer and pulverize, cross 10 mesh sieves, obtain mixing coarse aggregate; By red mud, bamboo powder, light magnesium oxide, active pozzolans mixing, put into mixer, continue to add the Xylo-Mucine being dissolved in 3 times of water gagings, pugging is stirred with the speed of 300 revs/min, then material is sent into granulation in tablets press, more obtained particle is pulverized, cross 200 mesh sieves, mix with the mud powder of surplus, obtain mixing fine aggregate;

(4) by above-mentioned mixing coarse aggregate, mixing fine aggregate, water glass and the mixing of all the other remaining components, add appropriate water mix even, control water content 15%, mixing fine aggregate is made to be wrapped in mixing coarse aggregate surface equably, form blank, then blank is put into dry-pressing formed machine dry-pressing formed, control pressure is 30MPa, again the base substrate made is placed in thermostatic drying chamber at the temperature of 105 DEG C dry 8 hours, finally send into sintering (first rapid temperature increases to 500 DEG C in resistance furnace, then 600 DEG C are warming up to the speed of 4 DEG C/min, continue again to be warming up to 1150 DEG C, it is 300 minutes that total firing time controls), cool rear taking-up and get final product.
