Description
Technical field
The present invention relates to a kind of water-purifying material, particularly a kind of to human body safety, broad-spectrum antimicrobial, can kill unwanted bacteria in the water, remove chlorine residue, removing heavy metals, material and preparation method thereof purifies water.
Background technology
Town water be mainly derived from tap water, pure water etc.Tap water is concentrated by municipal tap water company and is supplied with, generally speaking, the quality of water quality is decided by the water quality of central water supply, the individual can't select, although Running-water Company and each waterworks all guarantee good water source, all done processing such as filtration, clarification, sterilization in the production process,, supplied with the civic tap water and met national domestic water standard through water quality detection, monitoring.But disinfection by chlorine itself may form halogenated hydrocarbon compound and feed water again and caused pollution, even tap water quality itself is qualified, but the very long pipe network of flowing through after dispatching from the factory, just give the user, some pipeline is long neglected and in disrepair, causes the outer pollutent of pipe to infiltrate, and tap water is polluted once more.At present, people generally believe, tap water is the mode of infection of objectionable impurities, in fact, people's breathing and skin absorption also may make the people absorb these objectionable impuritiess during shower, and domestic water is more through all respects of our daily life exactly, for example, shower water, kitchen water, clothes water for cleaning, health washing water.The water of particularly taking a shower, owing to directly contact with skin with the hair of human body, its purifying problem also should cause people's attention.
Antiseptic-germicide can be divided into natural, organic and inorganic three major types.Inorganic antiseptic mainly contains silver zeolite, silver-colored silica gel, active carbon of silver etc.Organic antibacterial agent has quaternary ammonium salt, guanidine class, organometallic compound etc.But the pharmaceutical chemicals of organic or inorganic antibacterial finishing agent easily causes environmental pollution and the key Kang Jun of human body is had certain damaging effect.And natural antibacterial agent is broadly divided into animal class, plant class, mineral substance mainly from the extract of crude substance, and all there is advantage in broad-spectrum antimicrobial at aspects such as security, persistence, thermotolerances, so its application and research more and more are subject to people's attention.
Golden cypress, the coptis, Root of Chinese Barberry are natural phant, its antibiotic effective ingredient is a h bark of a cork tree alkali, has a broad antifungal spectrum, in vitro tests to streptococcus aureus, streptococcus pneumoniae, diphtheria corynebacterium, Streptococcus viridans, dysentery bacterium (except Song Nei Shi), Hemolytic streptococcus, meningococcus, vibrio cholerae, anthrax bacillus all effectively or stronger restraining effect arranged, Bacillus subtilus, bordetella pertussis, tetanus bacillus also there are restraining effect, influenza virus, ameba, Leptospira, some dermatophytes are also had certain restraining effect.
At present, antibiotic water-purifying material mainly is an inorganic antibacterial material on the market, mostly is greatly to carry silver-colored inorganic antibacterial material.Along with the raising of health of people consciousness with to the attention of health, the development trend that pure natural plant type antibacterial water filtering material will Cheng Weiwei.
Chinese patent CN1544342 discloses a kind of nano water purifying material, preparation method and application of removing virus and bacterium, with the macromolecular material is that weighting agent, nano material are filtering bodies, high molecular nanometer water-purifying material and this preparation methods that can effectively handle the bacterium in the water, virus.The main component of material is the oxidation-hydroxide phase of aluminium: 35%～65%, and glass fibre: 15%～35%, Mierocrystalline cellulose: 15%～30%, wherein the particle diameter of oxidation-aluminium hydroxide is 20～80nm, specific surface area 200～750m
2/ g.
