Description
Technical field
The present invention relates to formaldehyde scavenger technical field more particularly to a kind of long-acting VOC removings applied to carpet for automobile
The preparation method of agent.
Background technique
VOC is the english abbreviation of volatile organic compounds (volatile organic compounds), world health
Organize (WTO) to total volatile organic compounds (TVOC) is defined as: fusing point lower than room temperature and boiling point between 50 ~ 260 DEG C
Volatile organic compounds general name.The main component of VOC has: hydro carbons, halogenated hydrocarbons, oxygen hydrocarbon and nitrogen hydrocarbon, it includes: benzene series
Object, organic chloride, freon series, organic ketone, amine, alcohol, ether, ester, acid and petroleum hydrocarbon compound etc..Interior VOC mainly comes
Derived from carpet in car, roof felt, instrument board plastic plate, seat and other decoration glue, wherein the interior carpet used, interior
The VOC volatile quantity of crest blanket and top felt is higher, this is directly related with binding material phenolic resin used in its manufacturing process,
The synthesis material that phenolic resin adhesive uses is formaldehyde, if reaction is not exclusively, free formaldehyde, the portion can be contained in adhesive
Divide formaldehyde to will increase the VOC of automotive interior, and contains in the materials such as plastics, fabric, material of paint, thermal insulation material that automobile uses
Organic solvent, additive and auxiliary agent etc. are discharged into car, also will increase the VOC value of automotive interior.Due to vapour interior space compared with
Small, good airproof performance, thus in automobile influence of the exceeded VOC to human body than VOC exceeded in room to the extent of injury of human body more
Greatly.
A kind of method of catalysis oxidation removal formaldehyde of United States Patent (USP) US 5,585,083 invention, inventor will
The platinum of 12wt% is supported on tin oxide as catalyst, and using the oxygen in air as oxidant, the catalysis oxidation of PARA FORMALDEHYDE PRILLS(91,95) is removed
There is good effect.The advantages of this method is that do not have the consumption of additional energy source that can reach low-temperature catalyzed degradation first in reaction
The effect of aldehyde.The rare earth oxide or complex rare-earth oxidate containing valuable metal of Chinese patent CN 1698932A gold-supported are catalyst, gold
Content when being 3wt.%, the effect of preferable catalytic degradation formaldehyde can be also obtained at a temperature of 100 DEG C or so.But two special
Benefit all employs the expensive noble metal such as platinum and gold, and the price is very expensive for catalyst.102198404 B of Chinese patent CN
The silver-carrying nano manganese dioxide-catalyst of offer, using the manganese dioxide molecular sieve of silver-colored carried with doped as activating component, the catalyst
It catalysis oxidation formaldehyde can react at low temperature, by formaldehyde, complete oxidation is carbon dioxide and water under cryogenic, to go
Except formaldehyde.The patented method technique is more complex, and industrialization difficulty is larger.104984757 A of Chinese patent CN discloses one kind
The preparation method of formaldehyde quick removal agent, the formaldehyde quick removal agent equally use the higher metallic silver of price, and in order to
Reinforce removal effect, uses molecular sieve as strong adsorbent, while the product can not be made as liquid, quick removal effect is still
It is to be improved.
The above patented product uses limited time simultaneously, is unable to reach the effect of long-acting removal VOC, therefore the present invention proposes
A kind of preparation method of the long-acting VOC scavenger applied to carpet for automobile.
