In finishing, part adhesive etc. contains formaldehyde, and how to remove formaldehyde turns into a problem urgently to be resolved hurrily.
Bovine serum albumin, be a kind of globulin in cow's serum, containing 583 amino acid residues, comprising functional group
It can be acted on formaldehyde, CN101007203B reports a kind of amino acid type formol release agent and preparation method thereof, but single
Bovine serum albumin easily occurs to go bad, and causes other environmental pollutions.Titanium dioxide as a kind of excellent photochemical catalyst, to human body without
Evil, has been widely used in catalytic degradation formaldehyde field, CN103537294B reports a kind of tungstic acid of degradation of formaldehyde and answered
Close titanium dioxide optical catalyst.Chemical synthesising technology is that a kind of one kind that inorganic material is compound with organic, biomaterial is effective
Technology, it is widely used to the fields such as synthesizing bionic material, multifunctional material.Bovine serum albumin and inorganic catalysis material are answered
Close, prepare removing formaldehyde formulations and be rarely reported.
Therefore, one kind that exploitation green, environmental protection, high-efficient cleaning have become except formaldehyde formulations in environmental friendly material field is urgent
Demand.
The content of the invention
It is an object of the invention to：A kind of preparation method for removing formaldehyde formulations is provided, with reference to Measurement for Biochemistry and nothing
Machine, organic chemistry procedures, rapid batch prepare titanium oxide, manganese oxide and oxidation Magnesium coumpoud oxide, bovine serum albumin, dodecane
Base benzene sulfonic acid sodium salt, polyethylene glycol, the removing formaldehyde formulations of ethanol and water.
Technical scheme：First, in a certain amount of water, bovine serum albumin, surfactant sodium dodecyl base are added
Benzene sulfonic acid sodium salt and dispersant polyethylene glycol, water-bath temperature control, stirring, obtain solution A；Secondly, in a certain amount of ethanol, salt is added
Acid, under stirring condition, butyl titanate, anhydrous Manganese chloride and anhydrous magnesium chloride is slowly added to successively, stirring hydrolysis, obtains solution B；
Solution A and solution B are mixed, under water bath condition, stand reaction, while sodium hydroxide solution is added dropwise, adjusts pH value, agitation grinding
For a period of time, obtain uniformly removing formaldehyde formulations.
The present invention compared with prior art, has remarkable advantage：The removing formaldehyde formulations combine inorganic titanium dioxide, oxidation
Manganese, the formaldehyde degradation by photocatalytic oxidation process performance for aoxidizing Magnesium coumpoud oxide, compound bovine serum albumin, can effectively remove formaldehyde.
