Description
Technical field
The invention belongs to chemical field, be specifically related to a kind of environment-friendly highly efficient formaldehyde scavenger, this removing
Agent is primarily adapted for use in removes formaldehyde free in room air, artificial board, wallpaper and textile.
Background technology
Formaldehyde is a kind of colourless, readily soluble irritative gas, the strong poisonous substance matter being well recognized as, the murder by poisoning to human body
There is strong toxicity, be defined as suspicious teratogenesis, carcinogen by World Health Organization (WHO) (WHO).Formaldehyde can be through exhaling
Suction road absorbs, and by making tissue active oxygen increase, lipid peroxidation, affecting the immune system of body
Damage body etc. mode, cause bronchial asthma etc.；Formaldehyde also has stimulation to skin mucosa, can draw
Play allergic dermatitis, mottle, skin necrosis etc.；Except, formaldehyde also has strong carcinogenecity, can cause
Rhinocarcinoma, leukemia etc..And, high-concentration formaldehyde is to respiratory system, nervous system, immune system, liver all
There is harm.As can be seen here, the formaldehyde of formaldehyde especially high concentration, can seriously jeopardize health, it has to
People is allowed to pay much attention to.
The formaldehyde of the harm person, is mainly derived from following several approach:
One, comes from the indoor formaldehyde pollution that house fitting causes
The People's Republic of China (PRC) " formaldehyde sanitary standard in indoor air " (GB/T 16127-1995) specifies,
The acceptable concentration upper limit occupying indoor formaldehyde amount is 0.08mg/m3, but concentration of formaldehyde average out to after general house decoration
0.2mg/m3, reach as high as 0.81mg/m3, severe overweight.
Its two, come from artificial board, formaldehyde pollution that finishing material, textile middle reaches separate out
Formaldehyde, as industrial chemicals, can be used for synthesizing various binding agent, coating or textile auxiliary.With formaldehyde it is
All kinds of chemical products of Material synthesis, such as the plywood used in finishing, the artificial board such as particieboard, wallpaper,
The finishing material such as wall paper and paint, or textile etc., the formaldehyde of residual the most all can be had to dissociate
Come.
For above-mentioned two class formaldehyde pollution, in the market formaldehyde scavenger products, generally according to physical absorption
Or the processing mode of chemisorbed eliminates removing residue formaldehyde, but following technological deficiency can be there is:
(1) using physical absorption, such as activated carbon, bamboo charcoal etc., adsorbance is limited, and uses inconvenience, warp
Often need to change, form secondary pollution；
(2) chemisorbed is used, although process effect of formaldehyde good, but the compound poison added in scavenger
Property relatively big, inadequate environmental protection, as the Chinese invention patent of Application No. 201410542797.8 discloses a kind of first
, containing hydrazides (hydrazine class compound has formaldehyde removing effect), in using, there is free hydrazine in aldehyde scavenger,
Poisonous, environmental pollution can be caused after life-time service, and affect the user health in room；
(3) using effect of part commercially available prod can be limited by applied environment, in most formaldehyde scavengers
A kind of indoor first is disclosed containing titanium dioxide, the such as Chinese invention patent of Application No. 201210279279.2
Aldehyde pollution cleanup catalyst, containing titanium dioxide, grass acid dihydrazide etc., owing to titanium dioxide is ultraviolet catalytic
Agent, therefore under natural light or no light condition, the removal effect of formaldehyde is extremely limited, and has application limitation.
In sum, how the weak point of formaldehyde scavenger on existing market is improved, develop one
Kind efficiently, the formaldehyde scavenger of environmental protection, be those skilled in the art's technical barriers of being badly in need of solving.
Summary of the invention
