Description
Technical field
The present invention relates to a kind of floor board block.
Background technology
The expert thinks, after " coal smoke type ", " photochemical fog type " polluted, it was the 3rd pollution period of sign that the modern is just entering with " room air pollution ".According to statistics, the whole world nearly half people be in the room air pollution, and indoor environmental pollution has caused 35.7% breathing problem, 22% chronic lung disease and 15% tracheitis, bronchitis and lung cancer.Investigation shows that the modern on average has 90% time live and work indoor.The degree of room air pollution then exceeds several times than outdoor in the modern city, and more alarming is that children are than the easier harm that is subjected to room air pollution of adult.A investigation from the BJ Children's Hospital has ninety percent infant family once to fit up in half a year in the leukemia children that this institute sees and treat patients.The expert infers that in view of the above the hazardous substances in the indoor hardware fitting may be a major incentive of childhood lymphoblastic leukemia.The World Health Organization announces that the whole world has 100,000 people to die from asthma because of room air pollution every year, and 35% is children wherein.According to statistics, Chinese children asthma morbidity rate is 2%～5%, and wherein 1 to 5 years old children's morbidity rate is up to 85%.Comprehensive survey shows that building and ornament materials, ventilation and air conditioning system, office equipment and household electrical appliance etc. are IAQ (indoor air quality) most important " recessive killers ".Along with the development of polymer chemistry, present constructional materials is replaced by high performance plastics and iron and steel gradually by in the past post and panel structure.Insulation materials, house decorative material, coating and various furniture, wall, floor surface oil plant, elegant in appearance, the economical and practical chemical article of also many uses.National health, construction and environmental administration once carried out a house decorative material selective examination, found that the material with toxic gas pollution accounts for 68%, these ornament materials can volatilize the volatile organic compound of kind more than 300, as formaldehyde, trichloro-ethylene, benzene, dimethylbenzene etc., in case enter family, will cause various diseases, comprising 30 several diseases such as respiratory tract, alimentary canal, Neurology, vision, hypertension, wherein formaldehyde, benzene, trichloro-ethylene etc. are known carcinogens.Building self also may become the pollution sources of room air.A kind of is to have added chemical substance in the building operations, and the antifreezing agent that adds when for example north of china in winter is constructed oozes out toxic gas ammonia.Another kind is the radon that is formed by the radioactive substance in stone material, floor tile, the ceramic tile in underground and the building, and this is a kind of natural radioactive gas of colorless and odorless, and is very harmful to human body.In increasing modern office equipment and household electrical appliance inlet chamber, consequent air pollution, noise pollution, electromagnetism involve that electrostatic interference, ultraviolet radiation etc. give people healthyly brings very important influence.Air-conditioning is universal day by day in the modern life, causes human body, room and air conditioner at last in the circulating system of a sealing of indoor formation, as easy as rolling off a log microorganisms such as bacterium, virus, mould is multiplied in a large number.In addition, cook and the metabolism of Indoor Combustion such as smoking and human body self and the volatilization of various domestic refuses also are the sources of room air pollution.Oil smoke in the kitchen and the smog composition in the cigarette are extremely complicated, have analyzed more than 3800 kind of material at present.They exist with gaseous state, aerosolized in air, and wherein gaseous material accounts for 90%, have many materials to have carcinogenicity in gaseous material.Even (green) constructional materials or ornament materials of environmental protection, though they self or the hazardous substances that discharges be up to standard, they do not have the function of removing indoor hazardous substances.
Summary of the invention
The objective of the invention is for solving the constructional materials or the ornament materials of existing environmental protection, though they self or the hazardous substances that discharges be up to standard, they do not have the problem of removing indoor hazardous substances function, and a kind of floor board block that has active carbon is provided.First kind of technical scheme of the present invention is by wearing layer 1, decorative layer 2, substrate layer 3, balance layer 4, active carbon 5 and ventilative interlayer 6 are formed, fixedly connected with the end face of decorative layer 2 in the bottom surface of wearing layer 1, fixedly connected with the end face of substrate layer 3 in the bottom surface of decorative layer 2, the bottom surface of substrate layer 3 is provided with groove 9, the end face of balance layer 4 is fixedlyed connected with the bottom surface of substrate layer 3, have groove 9 corresponding through holes 10 on the balance layer 4 with substrate layer 3 bottom surfaces, active carbon 5 is fixed in the through hole 10 of the groove 9 of substrate layer 3 bottom surfaces and balance layer 4, and the end face of ventilative interlayer 6 is fixedlyed connected with the bottom surface of balance layer 4.Second kind of technical scheme of the present invention is made up of wearing layer 1, decorative layer 2, substrate layer 3, balance layer 4, active carbon 5, ventilative interlayer 6 and quiet layer 7, fixedly connected with the end face of decorative layer 2 in the bottom surface of wearing layer 1, fixedly connected with the end face of substrate layer 3 in the bottom surface of decorative layer 2, fixedly connected with the end face of balance layer 4 in the bottom surface of substrate layer 3, fixedly connected with the end face of quiet layer 7 in the bottom surface of balance layer 4, have first through hole 8 on the quiet layer 7, active carbon 5 is fixed in described first through hole 8, and the end face of ventilative interlayer 6 is fixedlyed connected with the bottom surface of quiet layer 7.The third technical scheme of the present invention is made up of wearing layer 1, decorative layer 2, substrate layer 3, balance layer 4, active carbon layer 11 and ventilative interlayer 6, fixedly connected with the end face of decorative layer 2 in the bottom surface of wearing layer 1, fixedly connected with the end face of substrate layer 3 in the bottom surface of decorative layer 2, fixedly connected with the end face of balance layer 4 in the bottom surface of substrate layer 3, active carbon layer 11 is fixed on the bottom surface of balance layer 4, and ventilative interlayer 6 is fixed on the downside of active carbon layer 11.
Active carbon is a kind of very little microstructure object, a lot of micropores are arranged in the crystal, this makes active carbon that very big inner surface be arranged, its developed area is 500～1700 meters squared per gram, the micropore capillary tube that this quantity is very many has very strong adsorption capacity, can fully contact with airborne various pernicious gases, and play absorption, filtration and catharsis.The present invention contains active carbon, can improve indoor air quality with there being the pernicious gas in the room on this floor to adsorb timely, filter and remove.That the present invention has is simple in structure, processing and fabricating convenient, the lasting advantage of absorption, filtration and scavenging action of pernicious gas.
