Background technology

For most of people, no matter to work, studying or living, people's most of the time is all spent indoor.Although topsoil is familiar with by people already to the harm of HUMAN HEALTH, to just having transferred to gradually in the harm of room air pollution to HUMAN HEALTH to twentieth century people's since mid-term attention.The kind of room air pollution is many, source of pollution are more extensive, and influence factor is also very complicated, and is often more serious than outdoor to the harm that HUMAN HEALTH causes.IAQ (indoor air quality) research has become a new important component part in the environmental science, causes people's extensive concern in recent years more.

Indoor environment is that people contact one of frequent, the closest external environment, and people have the time more than 80% to spend indoor approximately, with duration of contact of indoor air pollutants more than outdoor.Weak crowds (healthy weak population) such as therefore, the quality of IAQ (indoor air quality) can be directly connected to everyone health, and is especially old, weak, sick, residual, young, pregnant.Cause the major cause of indoor pollution, the one, because the source and the kind of indoor pollutant increase day by day.Along with growth in the living standard, the kind of the consumption of household fuel, the usage quantity of edible oil, cooking dish and quantity are all constantly increasing; Along with increasing of Chemicals, the civil nature chemical products such as various material of construction, finishing material, wood-based plate furniture that can volatilize objectionable impurities in a large number enter family, thus people in the kind of indoor contact objectionable impurities and quantity than showed increased in the past.The 2nd, because the airtight degree of buildings increases, indoor pollutant is difficult for diffusion, has increased the chance that the crowd contacts with pollutent.Along with world energy sources day is becoming tight, comprise that many countries of developed country all attach great importance to save energy, many buildingss all are designed and build very airtightly.Use the room of air-conditioning also to reduce entering of resh air requirement so that the amount of saving energy as far as possible.Therefore, had a strong impact on indoor ventilation.Because indoor pollutent can not in time be discharged outdoorly, causes a large amount of accumulations indoor, and outdoor oxygen causes indoor oxygen content on the low side normally in the inlet chamber.

This shows that indoor pollution is bigger to people's hazardness.Yet, still do not have cheapness at present and effective means and device prevent and the decontamination chamber internal contamination.

Summary of the invention

The present invention is intended to effectively prevent and the decontamination chamber internal contamination; the protection people's is healthy; can organically combine in indoor culture, physical culture, recreation with people and provide a kind of; energy active adsorption and decomposition harmful substances in air; room air is purified, is easy to make and the MULTILAYER COMPOSITE type nano-coating material of cheap tool air-cleaning function.The present invention also aims to provide the purposes of this coated material.

For achieving the above object, the invention provides a kind of MULTILAYER COMPOSITE type nano-coating material of tool air-cleaning function, this material is made of basic unit and the nano photo-catalytic material layer in basic unit, described basic unit is that the nano titanium oxide of 10～100nm mixes and to form by gac, nontoxic rubber cement and particle diameter, and described nano photo-catalytic material layer is that the nano titanium oxide of 10nm～30nm is formed by nontoxic rubber cement and particle diameter.

Gac is powdery or fibrous activated carbon, and nontoxic rubber cement is nonpoisonous emulsion, lacca glue.

The present invention also provides the purposes of the MULTILAYER COMPOSITE type nano-coating material of this tool air-cleaning function, and this coated material is used to make body building combination mat or purifying air wall chart.

Contribution of the present invention is that it is for preventing from and the decontamination chamber internal contamination, purify the air of a room to provide a kind of effective means.Because MULTILAYER COMPOSITE type nano-coating material of the present invention is made of the active carbon layer with good adsorption properties and little, nano photo-catalytic top layer with photocatalysis; therefore obnoxious flavour and material in not only can absorbed air; and can be by indoor fluorescent lamp light action in photocatalyst layer; adsorbed obnoxious flavour and material continuous and effective are decomposed; reach long-acting purifying air purpose, protect indoor environment and people healthy effectively.Simultaneously, because coated material of the present invention can be made into the motion combination mat, or be coated on sweat shirt outside and indoor and outdoor wall, the road surface, or be made into wall chart, so have multiple functions such as environmental protection and motion, body-building, art with art and value of environmental protection.
