Abstract

The composition of said invented environment-protecting type water-permeable brick is composed of (wt%) 75%-85% of bauxite granule material with 6-35 meshes, 7%-10% of clay fine powder with 250-300 meshes, 3%-6% of talcum powder and 4%-8% of bentonite. Said invented water-permeable brick is made up by using the above-mentioned materials in which the bauxite granule material is used as main material through the process of baking at high temperature. Said product has high strength, high hardness, strong bearing capacity and excellent water permeability, and its water-permeable rate can be up to 21mm/s.

Description

The permeable brick of environment-friendly type

(1) technical field

The present invention relates to a kind of floor tile that is used to lay the walkway, the permeable brick of particularly a kind of environment-friendly type.

(2) background technology

Mostly city side walk slab's road surface sclerosis at present is to adopt the method for laying marble, ornamental brick, cement brick to realize.Though the road surface of adopting above-mentioned materials to lay out has neat and artistic and the dust-proof effect, also comes with some shortcomings:

1, because its water-permeable extreme difference has directly been blocked the infiltration of rainwater, consequently causes the urban groundwater source to can not get replenishing, increased the weight of the arid phenomenon in city;

2, the reflection of road surface sunlight has increased the tropical island effect in city greatly;

3, very harmful to environmental protection, the plant protection in urban district, directly have influence on the growth of flowers, plants and trees.

(3) summary of the invention

Purpose of the present invention provides a kind of the have good water permeability and the permeable brick of environment-friendly type of reflection ray not with regard to being to overcome above-mentioned weak point of the prior art.

Purpose of the present invention can realize by following measure:

The each component ratio of weight and number of the permeable brick of this environment-friendly type is as follows: granularity is 6-35 purpose bauxitic clay particulate material 75%-85%, 250-300 purpose well as clay fines 7%-10%, talcum powder 3%-6%, wilkinite 4%-8%.

Granularity described in the present invention is a 6-35 purpose bauxitic clay particulate material, be with bauxitic clay directly after crusher in crushing, form by the vibratory screening apparatus screening again; It is to be used for the main raw material of grown place face brick.

Granularity described in the present invention is a 6-35 purpose bauxitic clay particulate material, be to add 4%-8% color dye additive by 250-300 purpose bauxitic clay powder 90%-96%, after mixing, moulding, oven dry, calcining, fragmentation forms again, and it is the auxiliary material that is used for producing colour floor tile; The concrete color of described color additive can be selected according to customer need; Described bauxitic clay contains AI ₂O ₃70%-80%.

Because permeable brick of the present invention is that employing 6-35 purpose bauxitic clay particulate material is main, form through high-temperature firing, this just makes product of the present invention remove to have high strength, high rigidity, supporting capacity is strong and characteristics anti-skidding, freeze proof, extinction, main is that it also has good water permeability (through actual measurement, its permeation rate can reach 21mm/s).That is, use floor tile of the present invention not only can solve influences pedestrian walking because of surface gathered water problem, supplementary question that also can fine solution urban groundwater source is regulated urban environment, for the growth of urban district green plants provides favourable condition.

(4) embodiment

The present invention is described in further detail below with reference to embodiment:

Embodiment 1:

A, to get granularity by ratio of weight and the number of copies be that 15 purpose bauxitic clay particulate material 80% (will contain AI ₂O ₃The bauxitic clay of 70%-80% is after crusher, twin rollers fragmentation, form by vibratory screening apparatus screening again), 250-300 purpose well as clay fines 7%, talcum powder 6%, wilkinite 7%, the water that adds above-mentioned gross weight 5%-8% stirs fully, and the time is about 30 minutes;

B, the compound that stirs is put into model shake moldedly under the pressure condition of 500-800 ton, the time is controlled at 10-15 second;

C, the adobe after being shaped sent in the baking room dries:

The loading of kiln calcining is carried out in d, the adobe after will drying, and temperature is controlled between 1250-1280 ℃, keeps getting final product in 100-120 minute.

The product that present embodiment is produced is not for the common floor tile of color.

Embodiment 2:

A, to get granularity by ratio of weight and the number of copies be that 300 purpose bauxitic clay powder 90%-96% add 4%-8% grass green dye additive, the water that adds above-mentioned gross weight 4%-8% stirs fully, after mixing, go into mold forming, and after drying, calcine by traditional technology, the broken again grass green bauxitic clay particulate material of making about 20 orders;

B, get grass green bauxitic clay particulate material 80%, 250-300 purpose well as clay fines 7%, talcum powder 6%, wilkinite 7% by ratio of weight and the number of copies, the water that adds above-mentioned gross weight 5%-8% stirs fully, and the time is about 30 minutes;

C, to get granularity by ratio of weight and the number of copies be that 15 purpose bauxitic clay particulate material 80% (will contain AI ₂O ₃The bauxitic clay of 70%-80% is after crusher, twin rollers fragmentation, form by vibratory screening apparatus screening again), 250-300 purpose well as clay fines 7%, talcum powder 6%, wilkinite 7%, the water that adds above-mentioned gross weight 5%-8% stirs fully, and the time is about 30 minutes;

D, get the bottom that 70% c puts into model by ratio of weight and the number of copies, get 30% b again and put into model in the mode that covers the c top, it is molded to shake under the pressure condition of 500-800 ton, and the time is controlled at 10-15 second;

E, the adobe after being shaped sent in the baking room dries:

The loading of kiln calcining is carried out in f, the adobe after will drying, and temperature is controlled between 1250-1280 ℃, keeps getting final product in 100-120 minute.

The product that present embodiment is produced is a colour floor tile.
