Description
Technical field
The present invention relates to environmental protection technical field more particularly to a kind of formaldehyde scavenger and preparation methods.
Background technique
Formaldehyde can form formaldehyde-protein complex, make protein denaturation, eyes clinically occur in conjunction with protein
Shouting pain, respiratory tract such as seriously stimulate and have a headache at the symptoms.Trace formaldehyde can generate dichloride methyl ether with hcl reaction in air and cause
Cancer object.High-concentration formaldehyde is all toxic to nervous system, immune system, liver etc., and can cause leukaemia, is potential strong cause
One of mutation-ure.
Wood-based plate includes density board, lumber core, glued board etc., and density board is also referred to as fiberboard, be with wood fibre or other
Plant fiber is raw material, applies Lauxite or other applicable adhesive after impregnating in water, through defibrator process, mat formation, hot pressing and
At artificial board.Due to having used urea formaldehyde resin adhesive in plate, thus foreign gas formaldehyde can be released.Wood-based plate is released
The formaldehyde source put: (1) free formaldehyde of reaction in Lauxite synthesis is had neither part nor lot in；(2) formaldehyde discharged when adhesive solidifies；
(3) formaldehyde that plate glue-line is generated by acidic moisture hydrolysis contains a certain amount of methylol and shakiness in Lauxite
Determine methene chain, slowly releases formaldehyde.This formaldehyde namely in indoor furniture will discharge completely needs nearly 10 years originals
Cause.It can be seen that formaldehyde is to generate remaining impurity after Lauxite, as long as removing the impurity in wood-based plate adhesive,
The volatilization of formaldehyde can effectively be inhibited.
The method of existing purifying formaldehyde mainly has: 1. room ventilation；2. plant absorption method, effect is too slow, and effect is unknown
It is aobvious；3. physisorphtion mainly adsorbs harmful substance using certain substances for having adsorption capacity, reaches the mesh for eliminating indoor pollution
's.The porous material such as active carbon, molecular sieve of common high-ratio surface makees adsorbent.4. photocatalyst method, common catalyst are
TiO2, by night it is unglazed limited so that formaldehyde removal efficiency is lower under physical condition；5. negative aeroion technology, mainly
Select have obvious fuel factor rare mineral stone be raw material, be added in materials for wall, when being contacted with air, ionized air and
Moisture in air generates anion, can polarize, and discharge outward, plays the role of purifying air；6. chemical method is
Nucleophilic addition occurs for short-term effective method, the substance and formaldehyde that hydroxyl, sulfydryl or amino group are such as had by chemical reagent
Reaction achievees the purpose that remove formaldehyde in air.
The compound of formaldehyde scavenger mainly exists in form of an aqueous solutions at present, or separately as aqueous formaldehyde scavenger
Sprinkling for plaque surface is handled, itself cannot form a film, and the formaldehyde scavenger of oil-soluble, and use process can be at
Film is mainly closed rather than removes formaldehyde, and after close membrane destruction, most of formaldehyde is still dispersed into room air.
Therefore the present invention study it is a kind of can be attached to furniture surface and continue PARA FORMALDEHYDE PRILLS(91,95) decomposed and be easy to be stripped
Formaldehyde scavenger.
Formaldehyde scavenger provided by the invention is lower using simply, requiring use condition, and applicability is wider, is especially suitable for
Family uses.
