Abstract
The present invention provides a kind of aldehyde remover and preparation method thereof for removing fur free formaldehyde, which includes following components: reactant, and 1~4 part；Surfactant, 0.2~0.5 part；Solvent, 0.5~1.0 part；PH adjusting agent, 0.2~0.5 part；150~15 parts of water.Fur formaldehyde scavenger provided by the invention forms a kind of carbanion by reactant under neutral or weak base, reacts under certain temperature and pH with formaldehyde and generates hydroxy compounds.Fur formaldehyde scavenger provided by the invention not only except effect of formaldehyde is good, but also will not destroy the feel and performance of skin.
Description
Technical field
The present invention relates to field of material technology more particularly to a kind of fur formaldehyde scavenger and preparation method thereof.
Background technique
Formaldehyde is cheap and easy to get and function admirable, is widely used on leather and fur production, can be used as leather fur tanning agent,
Fixative.The resin material of some production furs also contains formaldehyde, or some materials may decomposite first in products storage
Aldehyde.Formaldehyde is volatile, has strong impulse effect to the smell of people, eyes and mucous membrane etc., can also cause the mistake of certain human bodies
Quick reaction.After formaldehyde sucking or infiltration human body, body immunity can be caused to decline, even result in gene mutation, cause cancer, it is right
Human body causes great damage.Many countries are very strict to the content of formaldehyde limitation in fur goods.As child clothing, toy limit
Amount is lower than 30mg/kg；The furnishings limitation 75mg/kg of adult's contact skin.And common fur goods is often higher than 100mg/
kg.Therefore, it is necessary to invent a kind of aldehyde remover that can be removed fur free formaldehyde and not destroy fur quality.
