Abstract

The present invention relates to a water permeable ceramic brick and a production process thereof, which belongs to the technical field of ceramic wall and floor bricks. The water permeable ceramic brick is particularly suitable for the pavement of the drainage systems of squares, roads and other public places for rain water leakage quickly. The water permeable ceramic brick which is prepared from waste wall and floor brick grains as main raw materials solves the problems of high water permeable rate, high respiratory performance, high wear resistance, etc. The present invention has the technical scheme that (by weight percent) 70 to 90 wt% of waste wall and floor brick grains, 8 to 20 wt% of feldspar powder, 1 to 5 wt% of cellulose and 1 to 5 wt% of wood dust are ground, sieved, mixed, added with a proper amount of water, uniformly stirred, made into a blank, dried, sintered for 100 to 140 minutes at the firing temperature of 1100 to 1300 DEG C and cooled to form the water permeable ceramic brick. Because of the advantages of high water permeable rate, high respiratory performance and high wear resistance, the water permeable ceramic brick can become a mechanical pavement material in the mode of ecological benefit and environmental protection.

Description

A kind of ceramic water-permeable brick and production method thereof

Technical field

The present invention relates to the floor tile technical field, particularly a kind of ceramic water-permeable brick and production method thereof, it need to be specially adapted to the paving of public place water exhaust system such as rapid square, the road two that leaks rainwater is close to, stadium.

Background technology

At present, when building public places such as station, square, playground, road, all must consider the problem of the row of letting out rapidly to rainwater, thus below the square, road two is close to and all designed water exhaust system, as waterways etc.Generally all be to lay the concrete fragment of brick that has bakie on these gutter covers, or, be used to drain ponding just building the piece floor drain every one section long distance on the closely knit concrete fragment of brick paving.Because some rubbish all can be accumulated in road, square at ordinary times, add when heavy rain is near, the strong wind of following with many deadwoods, lose leaf and blow off to road, square, rainwater with these residual branches lose leaf, rubbish dashes to the ground leak and often stop up scupper, causes low-lying place ponding serious, can't the row of letting out, existing a large amount of rubbish, residual leaf etc. enter the waterways from scupper before stopping up, in the course of time, the waterways that can result in blockage has seriously weakened the water exhaust system function.

Summary of the invention

In order to address the above problem, need provide a kind of high permeability rate, high respiratory, attrition resistant ceramic water-permeable brick and production method thereof.

Technical scheme of the present invention is such: a kind of ceramic water-permeable brick, and it is a raw material with useless wall floor tile grain, Feldspar Powder, Mierocrystalline cellulose, wood chip, forms by following prescription sintering;

Prescription (by weight percentage):

Useless wall floor tile grain 70-90

Feldspar Powder 8-20

Mierocrystalline cellulose 1-5

Wood chip 1-5

Water is an amount of

It is undertaken by following processing step:

1. prepare burden: wall floor tile grain crushing screening 4-60 order will give up; The wood chip 20-60 order that sieves; Mierocrystalline cellulose obtains viscosity 400-600 degree with the water logging bubble of 10 times of weight; Feldspar Powder crushing screening 200-250 order; Add useless wall floor tile grain, Feldspar Powder, Mierocrystalline cellulose, wood chip by prescription, add an amount of water again and stir;

2. base: size is squeezed into base in accordance with regulations;

3. dry: at the roller kiln inner drying, its drying temperature is 100-130 ℃, and be 50-70 minute time of drying, and dry back moisture content is below 0.5%;

4. calcining: firing temperature is under 1100-1300 ℃ the condition, to calcine 100-140 minute;

5. cooling discharge divides grade packaged.

Ceramic water-permeable brick and production method thereof that the present invention proposes, it is that the raw material sintering forms with waste ceramic wall floor tile grain, Feldspar Powder, Mierocrystalline cellulose, wood chip, ceramic waste material is a main raw material, thereby has the unusual effect of utilization of waste material, protection environment.During high temperature sintering, bond mutually behind the waste ceramic wall floor tile grain melt surface, become the main body of the permeable brick of porous ceramics.The adding of Feldspar Powder helps base substrate waste ceramic wall floor tile grain melt surface more than 1000 ℃ the time, and fills its space, improves the intensity of product.Mierocrystalline cellulose mainly acts on the moulding of base substrate and the bonding of low thermophase.Fire into ashes when the effect of wood chip is high temperature, in the brick body, stay a large amount of spaces, thereby improved the permeability rate and the respiratory of product greatly.Simultaneously, above-mentioned ceramic water-permeable brick is to form the porous ceramics floor tile by boning between its particle and the particle after floor tile raw material punching press of coarse particles waste ceramic wall and the high-temperature calcination, so product surface is a kind of uneven surface of unartificial processing, has good skidproof effect.This ceramic water-permeable brick also has heat insulation, sound absorption function, can be applicable to the heat insulation double pumping equipment of top of building, the sound insulation of interior of building, heat insulation metope.

Utilize its high water-permeability and high respiratory, ceramic water-permeable brick has become the function surfacing material of the ecological and environmental protection mode of tool.If organic medium soilless culture grass blanket is planted above this ceramic water-permeable brick, because the permeable brick of this layer can be kept good the earth water cycle function, can rapidly rainwater be soaked into when being the rainy day in the earth, and when fine, can adopt for plant coming on the moisture content " suction " of the earth, keep a kind of ecotope of organic cycle, both have the glossy and green meadow of a slice, have the straightway water exhaust system of a slice again, also can prevent fault sag.
