Abstract

The invention discloses an ecological floor tile and a manufacturing method thereof. The ecological floor tile consists of a base layer and a surface layer, wherein the surface layer is adhered to the base layer through gradual distribution and vibration extrusion formation. Through a high-pressure steaming process, the manufactured ecological floor tile product has enough physical and mechanical properties, and reaches the requirements of national standard. The ecological floor tile product can be sold on the same day of production so as to alleviate the product occupation and accumulation on a storage yard and to accelerate the business capital turnover; and therefore, the waste utilization is achieved, the environment pollution is also reduced, the environment is beautified, and the requirements of circular economical development are met.

Description

A kind of ecological floor tile

Technical field:

The present invention relates to ecomaterial field, being specifically related to a kind of ecological floor tile for laying walkway, road surface, square etc. and preparation method thereof.

Background technology:

In recent years, China is in more than the 30 year time of reform and opening-up, carry out the urban construction of maximum-norm in the world, urban architecture density is too high, urban pavement mostly is non-ecomaterial, can not absorb water, store and discharge water, the havoc air ecological circulation of urban region, surface water ecological circulation, causes urban heat land effect.Because road surface can not absorb water, at rainy weather, rainwater not only can not infiltrate earth's surface in time to complete water cycle, and easily builds up and too fastly cause the phenomenon such as water logging street, water product path, easily causes traffic accident.Beijing, capital on the 23rd June in 2012 heavy rain causes whole city's traffic paralysis, is exactly case history.Therefore, earth material must have ecological property, the rainy day can absorb water, retaining, permeable, can Ecological water cycle be kept like this, can ensure that again surface gathered water amount is little, be conducive to ensureing the safety of traffic and unobstructed.

Summary of the invention:

The object of this invention is to provide a kind of porosity and be greater than 50%, water-intake rate ecological floor tile being greater than 30% and preparation method thereof.

The present invention is achieved by the following technical programs:

Described bottom prepare the raw material that material comprises following component and mass fraction: the slag granules after domestic garbage burning electricity generation: 40 ~ 50%; Gravel particle: 10 ~ 20%; Levigate sand: 5% ~ 15%; Lime: 5 ~ 15% and water: 5 ~ 10%;

Described surface layer prepare the raw material that material comprises following component and mass fraction: the bottom ash after domestic garbage burning electricity generation: 30 ~ 50%; Rubble: 30 ~ 40%; Levigate sand: 5 ~ 15%; Lime: 5 ~ 15%; With water: 5 ~ 20%.

Described ecological floor tile porosity is greater than 50%, and water-intake rate is greater than 30%.

Another technical scheme of the present invention, the preparation method of described ecological floor tile comprises the following steps:

1) prepare burden: by the slag granules by mass percentage after 40 ~ 50% domestic garbage burning electricity generations, 10 ~ 20% gravel particles, 5% ~ 15% levigate sand, 5 ~ 15% lime and 5 ~ 10% water mix and blend, obtain eco-concrete; By by mass percentage 30 ~ 50% domestic garbage burning electricity generation after bottom ash, 30 ~ 40% rubble, 5 ~ 15% levigate sand, the lime of 5 ~ 15% and the water of 5 ~ 20% be mixed into low slump concrete;

2) shaping: first bottom batching to be stirred in injection mould sequentially, vibrations compacting, and then after surface layer batching is stirred, inject vibrations extruding formation product base substrate in mould;

3) steam-cured: by the ecological pavement adobe demoulding of extrusion molding, and code piles up on steam pressure car, at 190 ~ 210 DEG C, high-pressure steaming and cultivating 8h under 1.5 ~ 1.8MPa condition, after cooling, namely obtain ecological pavement brick.

The present invention has the following advantages compared with prior art:

(1) adopt high-pressure steaming and cultivating technique, the oxide compounds such as the silicon-dioxide in waste can fast speed and calcium hydroxide generation chemical reaction and solidify, and the ecological pavement brick product of generation possesses enough physical and mechanical properties, and the requirement that is up to state standards;

(2) adopt high-pressure steaming and cultivating technique, reduce product curing cycle, product can be sold the same day, reduced product stockyard and took, and accelerated business capital turnover;

(3) utilize waste for raw material production, reduce the consumption of natural resources, both accomplished utilization of waste material, and can environmental pollution be reduced again, beautify the environment, meet recycling economy development.

Embodiment:

Below further illustrate of the present invention, instead of limitation of the present invention.

Embodiment 1:

(1) design the total layout of high-pressure steaming and cultivating ecological pavement brickwork skill, concrete permeable brick production technique and high-pressure steaming and cultivating technique are organically combined;

(2) by the slag granules by mass percentage after 40 ~ 50% domestic garbage burning electricity generations, 10 ~ 20% gravel particles, 5% ~ 15% levigate sand, 5 ~ 15% lime and 5 ~ 10% water mix and blend, obtain the eco-concrete preparing described bottom; Slag granules after described domestic garbage burning electricity generation and gravel particle are as aggregate, and described levigate sand and lime are as gelling material;

(3) by mass percentage 30 ~ 50% domestic garbage burning electricity generation after bottom ash, 30 ~ 40% rubble, 5 ~ 15% levigate sand, the lime of 5 ~ 15% mix with the water of 5 ~ 20% after, stir and obtain the low slump concrete slip preparing described surface layer;

(4) first bottom batching is stirred in injection mould sequentially, vibrations compacting, and then after surface layer batching is stirred, inject vibrations extruding formation product base substrate in mould;

(5) again by the ecological pavement brick Bear-grudge demoulding of extrusion molding, and code piles up steam pressure car, pushes autoclave, at 190 ~ 210 DEG C, high-pressure steaming and cultivating 8h under 1.5 ~ 1.8MPa condition, namely obtains ecological pavement brick after cooling.

Ecological pavement brick physicals detected result

By grade of compressive strength Cc30, and the ecological pavement brick that the ratio of the length of side and thickness is less than 5 detects, reference standard: JC/T945-2005, and measured actual result sees the following form:

Test item	Ultimate compression strength	Wear resistance	Water-retentivity	Coefficient of permeability k15	Freeze proof rate of loss R
						Standard limited value	＞30Mpa	Mill hole length < 35mm	＞0.6g/cm ²	＞1.0x10 ²cm/s	＜20%
