Background technology
With the aggravation of Development of Urbanization speed, urban surface is progressively by the water preventing ability such as building and various concrete
Material is covered, and waterproof regional percentage is significantly increasing, and its coverage rate of some areas is more than 80%.Due to the draining in city
Worse and worse, many cities one run into heavy rain to ability, and its rainwater on road surface can not quick seepage, it is easy to cause urban waterlogging.Cause
This, to solve urban surface hardening problem, builds high-quality natural living environment, safeguards balance of city ecosystem, environmental protection
Building material product-water-permeable brick arise at the historic moment, and be developed rapidly.At present, the conventional raw material of water-permeable brick is prepared main
There are waterworks sludge, many term red muds, gold tailings, flyash, glazed ceramic, concrete etc..And prepared by these raw materials
Water-permeable brick is typically necessary the high temperature sintering through 1000~1400 DEG C, wastes fossil fuel, and produces industrial waste gas and causes air
Pollution.
At present, in order to avoid energy waste and atmosphere pollution that high temperature sintering is caused, occur in that it is non-burning brick, it is but unburned
Brick is mainly that depended on pressure is compressing, and its internal bond strength is low, causes non-burning brick mechanical performance be not as excellent as fired brick, although
Non-burning brick mechanical performance can be improved by improving compressing pressure, but the increase of pressure can cause non-burning brick internal holes again
The reduction of gap rate, and then influence non-burning brick water permeability.
Therefore, a kind of baking-free water-permeable brick not only with good mechanical performance but also with excellent water penetration is invented to Building wood
Material preparing technical field has positive meaning.

Stone, immediately with liquid nitrogen spraying 10~15min of freezing processing, freezing processing is crushed after terminating, and it is 1~2mm's to filter out particle diameter
Basalt particle；
（2）Sonic oscillation is handled after above-mentioned basalt particle and dopamine solution are mixed, and is separated by filtration and is obtained filter residue；
（3）Mixed liquor is obtained after above-mentioned filter residue, sodium metasilicate and water are mixed, pH of mixed is adjusted to 5.0~5.5 with hydrochloric acid, then
To mixed liquor heat temperature raising, after 1~2h of stirring reaction, filtering, isolated modified filter residue；
（4）Mashing is handled after pericarp and water are mixed, and mixed serum is obtained, by gained mixed serum sealing and fermenting, fermentation ends
After filter, isolated ferment filtrate；
（5）Above-mentioned modified filter residue and Portland cement and bed-silt stirring is mixed to get compound, then will mixing
After material and above-mentioned ferment filtrate are by waiting mass ratio well mixed, 5~10min is stood at 30~40 DEG C, adobe material is obtained；
（6）Above-mentioned adobe material is injected in stainless steel mould, compacting obtains adobe, then by brick bat drying, you can obtain unburned ring
Protect water-permeable brick.
