Description

A kind of antibacterial corrosion resistant novel water permeable floor tile

Technical field

The present invention relates to building material technical field, particularly relate to a kind of antibacterial corrosion resistant novel water permeable floor tile.

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 a kind of antibacterial corrosion resistant novel water permeable floor tile.

The present invention is achieved by the following technical solutions:

A kind of antibacterial corrosion resistant novel water permeable floor tile, 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, perlite abandoned mine powder 12-14, cerium dioxide 7-8, tourmalinite 2-3, ammonium chloride 0.6-0.7, Vanay 2-3, vinyl acetate resin emulsion 1.5-2, discarded vitrified brick 20-22.

The antibacterial corrosion resistant novel water permeable floor tile of described one, 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) perlite abandoned mine powder is put into pulverizer to pulverize, cross 200 mesh sieves, the mud powder mixing of surplus, obtains mixing fine aggregate; Tourmalinite is put into pulverizer pulverize, cross 200 mesh sieves, mix with cerium dioxide, put into mixer, add Vanay, vinyl acetate resin emulsion, send into granulation in tablets press after stirring 15 minutes with the speed of 500 revs/min, obtain composite grain; Continue to put into pulverizer after waste gas vitrified brick is put into crusher fragmentation, obtain the particle of 3 millimeter, the brick particle that will give up mixes with above-mentioned composite grain, obtains mixing coarse 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.

Advantage of the present invention is: the present invention adopts sewage plant sludge as main component, can solve the reluctant problem of mud, reach the requirement of energy-conserving and environment-protective; The present invention is when disposing of sewage factory's mud, adopt double sintering technique, first the mud of half amount is sintered, again second half is added in the preparation of adobe respectively with the form of fine powder, by again sintering, the structure of through hole layer by layer can be formed, be conducive to the porosity improving brick body, thus can permeability rate be improved.

Tourmalinite, cerium dioxide add in the preparation of adobe by the present invention, have certain antibacterial, germicidal action; Employing vinyl acetate resin emulsions etc. are as tackiness agent, and the green brick forming plasticity made is good, and the adobe compactness after sintering is good, and porosity is high, antibacterial, corrosion-resistant, and raw materials cost is low, and technique is convenient to control.
