Description
Technical field
The present invention relates to one kind except formaldehyde spray and preparation method thereof.
Background technique
Construction material, furniture, artificial board, various binder coating and synthesis textile in interior decoration etc. can be released
Put a variety of gaseous pollutants, seriously pollute indoor environment, wherein formaldehyde be most typically in indoor environment, most serious pollutant it
One.The harm of Long Term Contact low dosage formaldehyde has: causing chronic respiratory disease, nasopharyngeal carcinoma, colon cancer, brain tumor, leukaemia etc.
Disease.With the raising that health environment-friendly is realized, people more pay close attention to the harm of Formaldehyde Pollution of Indoor Air.
The existing carbaldehyde Method that removes mainly includes following several: (1) biological enzyme: microorganism can produce by procreation itself
The organic matter of sources of odor especially formaldehyde can be thoroughly decomposed into titanium dioxide under the double action of microorganism and enzyme by biological enzyme
Carbon and water.But enzyme has the service life, and the incubation period of formaldehyde is up to 3~15 years, this means that is needed repeatedly using biological enzyme
It administers, if will fail after a period of time only with disposable spray finishing, is not able to satisfy the deenergized period of removal formaldehyde.(2) light
Membrane by accelerant process: can have formaldehyde present in the local constant analyst of light by visible-light activated photocatalyst, but
It is that catalyst particles breathe nocuousness to people, and have chemical attack harm.Therefore, it is direct to need a kind of safe and efficient, low price spray
Be sprayed on indoor formaldehyde rise on remove formaldehyde.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of safe and efficient, low price except formaldehyde spray and its preparation
Method.
The technical scheme of the invention to solve the technical problem is: a kind of remove formaldehyde spray, by following raw material and
Its mass percentage composition: surfactant 5~10%, methanal trapping agent 5~15% and surplus are water.
The surfactant is the combination of one or more of acrylic acid, dipropylene and polyvinyl alcohol.
The methanal trapping agent be the ratio of carboxyl chitosan and amino acid hydrochloride salt 2~4:1 in mass ratio mix and
At.
The amino acid hydrochloride salt is lysine hydrochloride, glutamic acid hydrochloride, histidine hydrochloride and cysteine
The combination of one or more of hydrochloride.
The above-mentioned preparation method except formaldehyde spray, comprising the following steps:
(1) methanal trapping is obtained after mixing the ratio of carboxyl chitosan and amino acid hydrochloride salt 2~4:1 in mass ratio
Agent is then added in the water of part, and the first mixed liquor is mixed evenly to obtain；
(2) surfactant is added in remaining water, stirs evenly to obtain the second mixed liquor；
(3) the second mixed liquor is added in the first mixed liquor, is stirred evenly to get formaldehyde spray finished product is removed, wherein respectively
Ingredient percent composition is as follows: surfactant 5~10%, methanal trapping agent 5~15% and surplus are water.
The surfactant is the combination of one or more of acrylic acid, dipropylene and polyvinyl alcohol.
The amino acid hydrochloride salt is lysine hydrochloride, glutamic acid hydrochloride, histidine hydrochloride and cysteine
The combination of one or more of hydrochloride.
Compared with the prior art, the advantages of the present invention are as follows: the present invention provides one kind and removes formaldehyde spray and preparation method thereof,
Its methanal trapping agent used is that carboxyl chitosan is combined with propylhomoserin hydrochloride with certain proportion, and carboxyl chitosan easily shows poly-
The property of electrolyte can promote imine group and formaldehyde on amino acid hydrochloride salt that nucleophilic addition occurs, generate and stablize
Mannich base.The free amine group being had in carboxyl chitosan molecule under the influence of the acidic-group on amino acid hydrochloride salt easily at
Salt keeps its amino characteristic more significant in cationic property, the absorption of promotion carboxyl chitosan PARA FORMALDEHYDE PRILLS(91,95) and nucleophilic addition, and two
Person, which mutually promotes, eliminates formaldehyde.
In conclusion the present invention is a kind of except formaldehyde spray and preparation method thereof, the formaldehyde spray that removes of production is sprayed on room
It is interior, as long as touching the formaldehyde that finishing material and furniture release, reacts rapidly, completely remove formaldehyde；Without additional light, electricity etc.
Under the conditions of energy consumption and chemical reagent, quick adsorption decomposing formaldehyde molecule is realized, the high-efficient, purification capacity with purifying formaldehyde
Greatly, the advantages that without secondary pollution.
