Abstract
The invention discloses a tar-based ground material to purify air, which comprises the following parts: 1%-15% tourmaline, 1%-20% optical catalytic material, 20%-50 % emulsified tar and 40%-70% quartz sand. The invention removes harmful organics and automobile tail gas effectively, which improves air quality and releases anion to eliminate peculiar smell without secondary pollution.
Description
Technical field
The present invention relates to a kind of earth material, specifically a kind of asphalt base ground material capable of purifying air.
Background technology
The human habitat pollution situation is on the rise in recent years, motor vehicle exhaust goes out a large amount of harmful organic substances and oxynitride, various finishing material also volatilize many harmful organic substances, reduce the Air quality that people are rely and breathed greatly, bring grave danger for human life and health, develop green technology efficient, energy-conservation, non-secondary pollution and be subjected to people's attention day by day.
Purposes such as after the nano titanium dioxide photocatalysis effect was revealed in 1972, that the free radical that utilizes nano titanium dioxide photocatalysis to produce is used for was antibiotic, purifying air and water purification are considered to a revolution in environmental protection field.The nanometer photocatalytic air purifying technology is primarily aimed at gas such as volatility organic pollutant such as NOx, SOx, formaldehyde and benzene in vehicle exhaust and the air, and nano-photocatalyst material can be converted into CO with these harmful dusty gass under photocatalysis
2And H
2O, thus reach the purpose that purifies air.
Negative ion is a kind of charged gaseous ion in the air, and it is one of sign of weighing the Air quality quality.Airborne negative ion can suppress effectively, kill airborne virus, bacterium, reduces the propagation of various transmissible diseases, eliminates pellet, thereby reaches the effect that purifies air.Negative ion can also stimulate the human body hemopoietic function effectively in addition, brings high blood pressure down, and improves cardio-pulmonary function, promotes cell metabolism, strengthens body immunity.
Tourmalinite is the anion-generating material that is most widely used at present, it be a kind of be the silicate minerals of the ring texture of feature, chemical constitution complexity with the boracic, be characterized in having piezoelectricity and pyroelectricity, under the situation of temperature, pressure change, can cause tourmalinite crystalline potential difference, make ambient air generation ionization, the electron attachment of being hit is in contiguous water and oxygen molecule and make it be converted into negative aeroion.The negative ion that takes place moves in air, gives bacterium, dust, smoke particles and water droplet etc. with negative charge transport, and electric charge combines with these particulates, can reach the purpose that purifies air.
Emulsified bitumen is a kind of common material of construction, and it has excellent extensibility, good adhesivity, the weather resistance on road surface, certain ventilation property and self-styled, and aqueous, environmental protective.Mixing tourmaline powder and nano-photocatalyst material with negative ion releasing function and purifying air effect in the emulsified bitumen slurry, make it possess the function that purifies air, is one of functional architecture Development of Materials direction.
Summary of the invention
The object of the present invention is to provide that a kind of raw material sources are extensive, technology is simple, lower-cost asphalt base ground material capable of purifying air, it can effectively be removed obnoxious flavour, sterilization, dedusting, purify air, improve Air quality, cost is moderate, and is easy to use, preparation technology is simple.
The object of the present invention is achieved like this:
A kind of asphalt base ground material capable of purifying air, it is the slurry like material that is formed through mixed preparing by emulsified bitumen, quartz sand, tourmalinite and nano-photocatalyst material, and its each component concentration is (by weight percentage): tourmalinite 1～15%, nano-photocatalyst material 1～20%, emulsified bitumen 20～50%, quartz sand 40～70%.
Described tourmalinite particle diameter is 60～400nm.
Described nano-photocatalyst material is rutile type nano titanic oxide or nanometer anatase titania or amphitypy blended nano titanium oxide.
Described emulsified bitumen is the building water-proof raw material.
Described quartz sand particle size is 80～120 orders.
The present invention compares with other earth material, and its difference is that it has air purification effect and negative ion releasing function.Its air purification effect mainly is that the photocatalysis by the photocatalyst nano titanium oxide produces, it not only PARA FORMALDEHYDE PRILLS(91,95), benzene series obnoxious flavour good Degradation is arranged, and can be with NOx a large amount of in the motor vehicle emission tail gas and SO
2Remove Deng gas cyaniding and final formation acid, therefore the effect that significantly purifies air is arranged, also have the function of disinfection simultaneously.In addition, the present invention introduces the tourmalinite with negative ion releasing function in asphalt base ground material, by to the tourmalinite technical finesse, make this material have stronger negative ion release performance, when purifying air, effectively discharge negative ion, greatly improve air quality.
Photocatalyst titanium dioxide of the present invention is owing to having adopted technical finesse, and is lower to the UV-irradiation requirement, even visible light can excite its activity.The present invention has adopted the tourmalinite with negative ion releasing function in addition, can effectively improve Air quality, thereby not only can be used for the various places of indoor and outdoor, as large-scale square, shopping center etc., also be applicable in the underground space environment, as underground parking, subway station, market place builet below the ground etc.
Embodiment
Acetylene used in the present invention (A) is the electric stone of super-refinement, nano-photocatalyst material (B) is rutile type nano titanic oxide, nanometer anatase titania or amphitypy blended nano titanium oxide, pitch (C) is emulsified bitumen, and used quartz sand (D) particle diameter is 80～120 orders.
Preparation technology is as follows:
1, component C is placed mixing machine (with the conical twin-screw mixer best results), start mixing machine, stirred 15～30 minutes, make its homodisperse;
2, add component A, B component and component D more successively in proportion, start mixing machine, stirred 1～2 hour, stop behind the thorough mixing;
3, with the slurry finished product loading barrel packaging that mixes.
Provide following embodiment in conjunction with content of the present invention
Because the difference of application scenario, air conditions also can change to some extent, therefore provides various prescriptions, uses according to practical situation, and various prescriptions are listed in the table below:
