Description
Technical field
The present invention relates to formaldehyde removing technical field, particularly relate to the preparation method of a kind of pure plant household formaldehyde scavenger.
Background technology
Inevitably using formaldehyde in the making of indoor hardware fitting and work progress, formaldehyde is a kind of colourless gas having intense stimulus type abnormal smells from the patient.After sucking high-concentration formaldehyde, can occur that the serious of respiratory tract stimulates and edema, eye twinge, headache with internal protein bound, induce bronchial asthma.Often suck a small amount of formaldehyde, chronic poisoning can be caused, mucous hyperemia, skin irritation disease, allergic dermatitis keratinization and fragility, nail matrix finger tip pain occur, anemia of pregnant woman sucks for a long time and may cause newborn teratogenesis, even dead, man sucks for a long time and may result in man's sperm deformity, death, sexual disorder, serious may result in leukemia, pneumothorax, reproductive performance lacks, and General Symptoms has headache, weak, cardiopalmus, has a sleepless night, loses weight and autonomic nervous dysfunction etc..
Minimizing technology for indoor pollution formaldehyde is more the most on the market, has physisorphtion, photocatalytic method, electrocatalytic method, small-molecule chemical formaldehyde adsorbent etc..Prior art is carried out except formaldehyde often through following prior art: 1, utilize the amino of ammonia or aminoderivative to react with formaldehyde, to reach except aldehyde purpose；2, utilize formaldehyde to have the feature of reproducibility, occurred by oxidizing species oxidation reaction to oxidize the formaldehyde into into organic acid therewith, to reduce the content of free formaldehyde；3, the porous, inorganic adsorbing material such as NACF, activity white clay, kieselguhr, bentonite, graphite is utilized to reach except aldehyde purpose；4, utilize Flos Jasmini Sambac, Flos Lonicerae, Flos Hibisci Mutabilis, Folium Mori etc. for raw material, synthesize a kind of environment-friendly type except aldehyde product；5, catalytic degradation class methanal trapping agent.These methods have certain defect, and physisorphtion easily causes secondary pollution；Photocatalysis needs ultraviolet, however indoor a lot of place cannot provide sufficient sunlight to irradiate and at night face photocatalytic degradation method invalid；Electrocatalytic method needs power supply and apparatus expensive to be easily damaged；It addition, a lot of small-molecule chemical formaldehyde adsorbents itself are poisonous and are difficult to store, unstable with the compound that formaldehyde generates, at room temperature just can decompose, easily cause secondary pollution.
Have now found that Aloe and there is the function absorbing the harmful gass such as indoor formaldehyde, carbon monoxide, sulfur dioxide, after protein in Aloe gel is hydrolyzed, aminoacid in hydrolyzate can be good at capturing formaldehyde molecule, and environmentally safe, except secondary pollution also will not be produced after aldehyde, there is good development prospect.The most also there are some plant formaldehyde scavengers, but complex manufacturing technology, and cost is high, is not suitable for industrialized mass.
