Description
Technical field
The invention belongs to technical field of air purification, and in particular to a kind of formaldehyde being mainly used for indoor green ordor removing is clear
Except agent.
Background technology
Formaldehyde can enhance the hardness of plank, and with insect prevention, corrosion-resistant as a kind of solvent with relatively strong bond
Effect, thus be widely used on furniture and finishing material.With further increasing for living standards of the people, interior decoration
Material application amount is growing day by day, and the exceeded phenomenon of Formaldehyde Concentration of Indoor Air is very universal, is generated to resident family's health serious
Threat.By toxicological analysis identification, formaldehyde is a kind of high toxicity protoplasm material, can damage the DNA in cell, is caused thin
The synthesis of non-program DNA, causes the gene mutation of cell in born of the same parents, has strong carcinogenesis to animal.
Currently, the method for removal formaldehyde is broadly divided into two class of Physical and chemical method both at home and abroad, Physical mainly utilizes object
The methods of reason absorption removal formaldehyde, price is low, applied widely, but except aldehyde is less efficient；Chemical method mainly by oxidation,
Decompose, complexing etc. reaction principles by develop formaldehyde catching agent come remove formaldehyde, purification air, this method have it is quick, kind
The feature that class is more, technical threshold is high, has been to be concerned by more and more people.However, this formaldehyde obtained using chemical method is caught
Agent is caught to be often possible to that new pollution problem can be brought.
Therefore, chemical method removes formaldehyde, and safety is the topic that user is concerned about the most.Current research shows biomass
For formaldehyde catching agent because deriving from natural biomass, big multipair environment and human body are nontoxic, and are easy to be biodegradable, while will not produce
The advantages that raw secondary pollution, is increasingly paid close attention to by researcher, has vast potential for future development.
Invention content
The object of the present invention is to provide formaldehyde scavengers that is a kind of safe efficient, while having ordor removing function again, reach peace
Entirely, green, quick, efficiently removal formaldehyde purpose, can promote and apply to the various formaldehyde removing needs of indoor and outdoor.
Therefore, the present invention provides following technical schemes：
A kind of formaldehyde scavenger, by weight percentage, the formaldehyde scavenger includes：Edible gelatin 0.1%-
1.0%, ispol 1% -5%, lemon extract 1% -3%, Flos Rosae Rugosae extract 1% -3%, chrysanthemum extract
1% -3%, phosphate mixt 0.1% -0.5%, remaining is water.
Further, the formaldehyde scavenger by 0.5% edible gelatin, 3% ispol, 1% lemon
Extract, 1% Flos Rosae Rugosae extract, 1% chrysanthemum extract, 0.5% phosphate mixt and 93% deionized water
Composition.
Specifically, the ispol refers to the mixture of low molecular weight active amino acid, such as glycine, third
Propylhomoserin, proline are mainly used for removing formaldehyde, can rapidly react with formaldehyde.In the present invention, three kinds of amino acid it
Between ratio be preferably 2：2：1.
Edible gelatin can cooperate with ispol to be reacted with formaldehyde, promote reaction efficiency, improve the removal effect of formaldehyde
Fruit.
Lemon extract, Flos Rosae Rugosae extract and chrysanthemum extract are obtained by the method preparation that low-temperature ultrasonic water extracts
, it, can quick covering smell wherein containing glucoside and polyphenol and Flavonoid substances, moreover it is possible to promote amino acid anti-with formaldehyde
It answers.
Phosphate mixt refer to comprising sodium tripolyphosphate, sodium pyrophosphate, calgon mixture, 1% it is water-soluble
Liquid pH value is 8.0, for adjusting solution ph to alkalescent, further promotes the efficiency of reaction, enhances the removal effect of formaldehyde.
On the other hand, the present invention also provides the preparation method of the formaldehyde scavenger, the method includes：
(1) by weight weighing edible gelatin, ispol, lemon extract, Flos Rosae Rugosae extract, chrysanthemum extraction
Deionized water is added in object；
(2) above-mentioned load weighted raw material is added in reaction kettle, is slowly added to phosphate mixt, stirs at normal temperatures,
Until dissolving；
(3) after standing, the formaldehyde scavenger of greenish transparent is obtained.
Preferably, in step (2), 25-40min, preferably 30min are stirred at normal temperatures.
Preferably, in step (3), 30min, preferably 30-40min are at least stood.
The formaldehyde scavenger that the present invention obtains is greenish transparent liquid, is sprayed by being atomized watering can when use.First
Aldehyde generates the methylol compound of solid powdery after encountering formaldehyde scavenger and is fixed on body surface, with clear water, that is, erasable
It wipes.
After each batch production, the shelf-life is about 2 years.
Beneficial effects of the present invention are：Remove all food-grades of agent prescription raw material, product pH value 6.5-8.5 it
Between, to human body, furniture surface without any injury, non-secondary pollution；Secondly, formaldehyde scavenger of the invention can be with formaldehyde in room
The lower rapid reaction of temperature, effectively removes rate up to 80% or more；Peculiar smell can quickly be covered and be eliminated；And reaction product is easy
It is dissolved in water, can be wiped and be removed with wet towel, is convenient to clean.
