Description
Technical field
The present invention relates to a kind of environmentally protective water-permeable bricks for purifying air and preparation method thereof, belong to the permeable of urban construction
Brick technical field.
Background technology
In recent years, since the serious urban waterlogging that heavy rain triggers annoyings the various regions common people, sponge city has become city
Sponge urban construction scheme has been formulated in idea of development and the important symbol of construction mode transition, existing more than the 130 a cities in the whole nation.It will
Sponge city is built, a kind of effective approach is exactly to be laid with big face in urban road, residential area, park plaza and parking lot
Long-pending water-permeable brick.
In addition, with increasingly increase of the rapid development and the people of automobile industry to vehicles demand, vehicle exhaust
As an important sources of urban air pollution.Wherein, in vehicle exhaust mainly there is harmful components：NOX, HC compounds,
CO、SO2, particulate matter etc., the vehicle exhaust largely discharged has become the public hazards of environmentally protective urban environment.For numerous sponges
Some porous pavements in city do not consider to play the popularity of its laying come the effect of reaching purification air.Other
Road surface, it is contemplated that purify the purposes of air, and cannot meet the needs of sponge urban water-through, city is still caused under rainstorm weather
City's waterlogging.A kind of physical absorption, is a kind of reversible physical action, will be released in situ after adsorption saturation in existing purification air
It puts, causes the pollution of bigger instead;It is another kind of effectively to be degraded using photocatalyst medium, but in view of time of contact is short and light
The two factors are difficult to ensure that according to intensity, and this method still remains the problem of efficiency is low.Therefore, it is empty to prepare a kind of energy high-efficient purification
The water-permeable brick of gas is of great significance for the sponge city for building environmental type.
The content of the invention
The invention mainly solves the technical problem of providing a kind of environmentally protective water-permeable bricks for purifying air, can ensure
On the premise of efficient permeability rate, vehicle exhaust and air-borne dust are effectively absorbed, harmful substance therein of degrading, and for a long time
Keep the effect of high-efficient purification air.
A kind of environmentally protective water-permeable brick for purifying air proposed by the present invention includes the raw material of following parts by weight：Overlay film bone
400-500 parts of material, 20-30 parts of bonding material, 5-8 parts of curing agent, 2-3 parts of adjuvant, 40-50 parts of activated carbon fiber, nanometer two
50-60 parts of titanium oxide.
In the present invention, the overlay film aggregate uses the natural siliceous sand of particle size 0.180-0.425mm, the overlay film bone
Material carries out overlay film using hot method, and preheating temperature is 130-180 DEG C, and the overlay film time is 1-2min, and curing agent is methenamine solution.
In the present invention, the adhesive substance is using one kind in E-12F thermosetting epoxy resins, E-12R, E-12 or E-20
Or it is a variety of, wherein：The epoxide number of E-12F thermosetting epoxy resins is 740-870, and the epoxide number of E-12R is 900-1000,
The epoxide number of E-12 is 740-1100, and the epoxide number of E-20 is 450-560.
In the present invention, the curing agent be alicyclic curing agent or modified aliphatic curing agent, the alicyclic curing agent
For 593 type of polyamines class, polyamines class H-113 types or polyamines class T-31 types, the modified aliphatic curing agent is by alicyclic solid
Some hydrophilic radicals are added in agent to prepare, the hydrophilic radical is any in hydroxyl, carboxyl or sulfonic group.
In the present invention, the adjuvant is polystyrolsulfon acid, and molecular formula is (C8H8O3S）nIt is a kind of large hydrophilic molecular
Class additive can make test block effectively extend its permeable timeliness while outstanding water permeability is shown.
In the present invention, the activated carbon fiber is phenolic aldehyde base ACF, and fibre diameter is 9-11 μm, specific surface area 1000-
2300m2/ g, external surface area are 1-1.2 m2/ g, average pore size 1.5-3.0nm.ACF not only has large amount of adsorption, also has
Absorption and desorption rate are fast, have the advantages that good adsorption capacity, adsorption layer are thin to low concentration substance, capable of purifying air.
In the present invention, the nano-titanium dioxide for diameter less than 100 nanometers, appearance for white loose powder, have
There is very strong " Superhydrophilic ", be not easy to form droplet on its surface, hydrocarbon can be acted under visible light illumination,
The harmful substance that degrading activity carbon fiber is adsorbed, remaining inorganic substances can be clean with rain drop erosion, reach automatically cleaning effect.
The making step of the environmentally protective water-permeable brick of the purification air is as follows：
1）Precoated sand is weighed according to formula to pour into agitated kettle, then sequentially adds uniformly mixed activated carbon fiber and nanometer two
Titanium oxide, bonding material, curing agent and adjuvant stir 4-6 minutes, obtain uniformly mixed mixture；
（2）Again by step（1）Obtained uniformly mixed mixture in a mold suppress by uniform distribution, application 10-20MPa pressure
60-120 seconds, obtain water-permeable brick test block；
（3）Finally gained water-permeable brick test block is sent to 50-70 DEG C of thermostatic curing stove, curing time is 50-70 minutes.
The beneficial effects of the invention are as follows：
（1）Raw material needed for the water-permeable brick of air is environmentally protective, which can meet sponge city for can purify prepared by the present invention
The requirement of city's pavior brick high intensity, high water-permeability energy and anti-skid wearable.
（2）The present invention is by active carbon fibre peacekeeping nano-TiO2It is combined with each other, it is better than the effect of homogenous material, it compensates for
The shortcomings that adsorption saturation of activated carbon fibre is non-degradable.Become irreversible for the adsorption reaction of harmful substance, reach " absorption-
The effect of degradation-elimination " can keep the effect of high-efficient purification air for a long time.
（3）The sand base water-permeable brick purification air significant effect of the present invention can effectively purify the NO of motor vehicle exhaust emissionX、HC
The pernicious gases such as compound, CO, while also have certain effect to absorbing air-borne dust, road ambient enviroment can be significantly improved, it can
The citizen such as park, parking lot, residential communities, square activity area is layed in extensively, to building environmental type sponge city tool
It is of great importance.
