Description
Technical field:
The present invention relates to chemical industry field, particularly a kind of living beings are except formaldehyde, the composition of benzene homologues and method for making.
Background technology
Formaldehyde is often used to manufacture glue class or coating is used on clamping plate or furniture, and its spill-out increases along with the rising of temperature, and formaldehyde concentration in confined space can accumulate, and the formaldehyde remaining in indoor can reach several years or many decades, and Long Term Contact can be carcinogenic.Subacute benzene poisoning can be there is after sucking higher concentration benzene in a short time, occur the symptoms such as dizzy, headache, weak, insomnia, paramenia, and alpastic anemia, acute leukemia can occur, show as the anaemia developed rapidly, hemorrhage, infection etc.The harm of benzene poisoning to health is summed up as 3 kinds: carcinogenic, disable, teratogenesis tire.Therefore, effectively remove and become problem in the urgent need to address by automobile or indoor formaldehyde, benzene pollution.
Now commercially existing a lot of formaldehyde scavenger and benzene homologues scavenger occur, from angles of product, existing formaldehyde scavenger and formolite reaction are comparatively slow, and elimination efficiency is low, DeGrain; Main component is the formaldehyde scavenger of rudimentary amine, although formaldehyde removing effect is better, self has certain toxicity, easily to environment in production and use procedure, easily causes secondary pollution to room; Benzene homologues and formaldehyde belong to different types of material, and existing scavenger majority is good to a kind of elimination effect of material, do not have which kind of scavenger all to have good elimination effect to these two kinds of materials.
From production angle, existing formaldehyde, benzene homologues scavenger manufacturing equipment and complex process, production cost is high.
State Intellectual Property Office's application number 201010265170.4 application documents disclose a kind of composite long-acting formaldehyde scavenger and preparation method thereof, to decide reactant with CARB OXYMETHYL-CHITOSAN and urea, utilize the film forming of CARB OXYMETHYL-CHITOSAN, close down the formaldehyde of outside slowly-releasing in object, it utilizes the micromolecular permeability of urea and diffusivity, the urea of part gos deep into catching free formaldehyde in it, but its permeability is undesirable, and separately it does not have elimination effect to benzene homologues.
Summary of the invention
The present invention is directed to the problems referred to above, provide a kind of living beings except formaldehyde, the composition of benzene homologues and method for making thereof, multiple harmful element can be removed simultaneously, there is no toxic and side effect; Penetrate into the better effects if catching free formaldehyde in material, realize the quick-acting catching formaldehyde, have benzene homologues simultaneously and well dispel effect, act on lastingly long-acting.
The invention provides the composition of a kind of living beings except formaldehyde, benzene homologues, said composition forms primarily of the component of following weight portion:
More than 95% deacetylation shitosan 2-6 urea 4-10 dodecyl sodium sulfate 2-6 sodium phosphate trimer 2-5 nanometer anion powder 2-5.
The present invention, on the basis of original shitosan and urea, adds nanometer anion powder, dodecyl sodium sulfate, sodium phosphate trimer three kinds of components; Nanometer anion powder is adsorbent, and releasing negative oxygen ion has osmosis to interior of articles, can catch free formaldehyde, improves and removes the long-lasting of formaldehyde; Dodecyl sodium sulfate, sodium phosphate trimer have good removal effect to benzene homologues, also play dispersion moisture-keeping function simultaneously, the better effects if that the living beings of preparation remove formaldehyde, the composition of benzene homologues removes formaldehyde, also good removal effect is had to benzene homologues, and have no side effect, in addition, deacetylating degree of chitosan of the present invention is high, better with formolite reaction.
Further improvement, described composition also comprises the thickener that parts by weight are 1-3 part, described thickener be selected from gellan gum, polyvinyl alcohol, honeybee vinegar one or more, selected thickener can improve the speed that living beings are reacted except the composition of formaldehyde, benzene homologues and formaldehyde and benzene homologues.
The JFC bleeding agent that parts by weight are 0.05-0.15 part is also comprised in described composition, adding of JFC bleeding agent can impel living beings to remove formaldehyde, the composition of benzene homologues penetrates into interior of articles, better scavenging action is played to the material such as formaldehyde and benzene homologues of interior of articles, removing more thorough.
Described composition also comprises the sodium chloride of citric acid that parts by weight are 0.5-1.5 part and 2-5 part, and the sodium chloride added improves the adsorbent removing speed of composition PARA FORMALDEHYDE PRILLS(91,95) and benzene homologues.
Described composition also comprises the defoamer that parts by weight are 0.1-0.3 part, and described defoamer is selected from silicone based defoamer.
Described composition also comprises 2% acetum of 30-55 part and the water of 35-60 part.
Preferably, this pharmaceutical composition is prepared from by the component of following weight portion:
Acetum 50 water 50 of more than 95% deacetylation shitosan 4 thickener 1 dodecyl sodium sulfate 4 sodium phosphate trimer 4 nanometer anion powder 3 citric acid 1 sodium chloride 3 urea 6JFC bleeding agent 0.1 defoamer 0.22%.
The present invention additionally provides the preparation method of pharmaceutical composition on the other hand, and the method step is as follows:
(1) more than 95% deacetylation shitosan is incorporated the acetum of 2%, be stirred to and be dissolved into solution A completely;
(2) thickener is added in the hot water of 80 DEG C 3/5ths to be stirred to and dissolve completely, be cooled to room temperature and form solution B;
(3) dodecyl sodium sulfate, sodium phosphate trimer being incorporated in remaining water when stirring, adding JFC bleeding agent, defoamer forms solution C;
(4) when stirring, in solution C, adding solution A and solution B, then add urea, nanometer anion powder, reconcile about pH=6-7 with citric acid, add sodium chloride, continue stirring 1 hour, ageing 3 hours, obtained described composition.
Living beings of the present invention, except the composition of formaldehyde, benzene homologues is except formaldehyde, benzene homologues successful, effectively remove multiple harmful element; Living beings of the present invention, except permanently effective, the non-secondary pollution of composition, safe and reliable of formaldehyde, benzene homologues, use very convenient.
Living beings of the present invention remove formaldehyde, the composition of benzene homologues is removed formaldehyde and had long-lasting; As long as by living beings except the composition of formaldehyde, benzene homologues is coated on the body surface of likely release formaldehyde and the benzene homologues such as body of wall, furniture, textile.
Living beings of the present invention reach 38 months except the composition action time of formaldehyde, benzene homologues, act on lastingly long-acting.And the equipment of generation and generating process are very simple, production cost is low.
