Description
Technical field
The present invention relates to the preparation method of a kind of seepage brick, belong to construction material preparing technical field.
Background technology
Seepage brick, is also water-permeable brick, Dutch brick, and the many employings of its raw material environment-friendly materials such as brick powder, slag, flyash that give up are
Primary low shapes, and its wearability is good, has good water penetration and water-retaining property, and antiskid function is strong, and it is not only with hard surface one
Sample can be beautified the environment, and has more preferable environment utilitarian function.When raining, rainwater can be penetrated into brick by seepage brick automatically
Beneath until earth's surface, recovery as far as possible, become subsoil water;When becoming a fine day, penetrate under brick or be retained in the water inside brick and can evaporate
In air, adjusting air humidity, reduces atmospheric temperature.
Traditional method uses bulky grain skeleton and cement composition or uses artificial treatment sand and high polymer binder to form.Water
Mud water-permeable brick or permeability rate is the highest, otherwise water permeability is permissible, but comprcssive strength is the highest, and this two aspects performance difficulty is taken into account;With
High polymer binder, artificial treatment sand water-permeable brick cost are high, it is impossible to promote on a large scale.And with flyash as primary raw material, preparation
Going out intensity is 30~90MPa, and porosity is the seepage brick of 40~50%.Although improve its intensity and increasing to a certain extent
Its porosity big, the problem solving grain composition, but this seepage brick porosity is high, intensity is low, infiltration coefficient is big, water conservation
Coefficient is little.
Summary of the invention
The technical problem to be solved: can not simultaneously hold concurrently for the seepage brick made with cement or bulky grain skeleton
Turning round and look at water permeability and comprcssive strength so that it is the problem that cannot promote on a large scale, discarded building flitch is mainly entered by the present invention
Row basification, obtains alkali and processes wood powder, after itself and dry gelatinized starch are stirred mixing and ball milling, with poly-vinyl alcohol solution
Stirring mixing, carries out fermentation process, is placed in mould being dried, and obtains the wood powder starch backbone that ferments, is then placed on
In brick mould, and its top layer is poured the mixture of mud and the water processed, carry out standing solidification, i.e. can be seeped water
Brick.The present invention is by by wood powder and starch blending and fermentation process, by microorganism to starch and the difference of wood powder corrosion rate,
Make wood powder remaining form micro hole structure, subsequently as skeleton, serosity is injected into skeletal internal, subsequently high temperature carbonization wood
Powder, after taking out carbon dust with oxygen reaction, can prepare simultaneously, and seepage brick intensity prepared by the present invention is high, and water permeability is good,
Can promote the use of on a large scale.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
(1) choose discarded building flitch, cleaned and naturally dry, subsequently comminution by gas stream sieving, prepare 65~70 mesh wooden

Heating 1~2h, filters subsequently and collects filter cake, is dried 6~8h at 130~150 DEG C, is prepared into alkali and processes wood powder;
(2) 1:5 in mass ratio, mixes corn starch with deionized water stirring and is placed in beaker, water-bath at 70~85 DEG C
Heating 25~30min, after its gelatinizing completes, continues Heat preservation rotary evaporated to dryness, collects and is dried gelatinized starch, subsequently
1:5 in mass ratio, processes wood powder by the alkali of dry gelatinized starch with above-mentioned preparation and is placed in ball grinder, 250~300r/min
Lower ball milling 1~2h, is prepared into ball milling mixed-powder;
(3) 1:5 in mass ratio, mixes the stirring of mass concentration 10% poly-vinyl alcohol solution and ball milling mixed-powder, 200~
After under 300W, sonic oscillation processes 10~15min, being placed in mould, under 5~10MPa after compacting, then sealing and fermenting processes 15
~20 days, after fermentation to be sealed completes, mould is placed at 85~100 DEG C and is dried 10~12h, be prepared into fermentation wood powder starch bone
Frame, standby;
(4) 1:10 in mass ratio, mixes the stirring of pond sludge and deionized water, under 200~300W ultrasonic disperse 20~
After 30min, sieve with the screen cloth of 60~80 mesh, collect lower floor mud and be placed at 95~100 DEG C being dried 6~8h, subsequently
Dry lower floor mud is placed in ball grinder, sieves after ball milling 3~5h under 650~700r/min, be prepared into 100~120 mesh
Mud granule;
(5) fermentation wood powder starch backbone prepared by step (3) is placed in rustless steel brick mould, 1:2 the most in mass ratio, will
Deionized water mixes with mud granule stirring and pours to fermentation wood powder starch backbone top layer, treats uniformly to be paved with rustless steel brick mould
After tool, more at room temperature standing solidification 20~24h, the demoulding subsequently is placed at 1000~1050 DEG C being fired into brick, natural cooling
A kind of seepage brick can be prepared into room temperature.
The seepage brick porosity prepared by the present invention reaches more than 75.6%, and intensity is up to 60~95MPa, and infiltration coefficient reaches
3.56×10-2More than cm/s, 25 freeze-thaw cycle, comprcssive strength loss rate≤16%, water-retaining property is more than 0.7g/cm3。
