Abstract
The formaldehyde absorbent is used to absorb formaldehyde released by indoor decorating material and no-ironing fabric. The formaldehyde absorbent consists of formaldehyde absorbing matter, filming agent, water and supplementary material. The formaldehyde absorbent has no color, no smell and no harm, reacts with formaldehyde to produce stable chemical compound, and is suitable for use in household.
Description
Patent of the present invention relates to a kind of chemicals that is used to absorb formaldehyde, particularly furniture, the floor that produces at the various artificial boards of various usefulness; Paint, coating; And fabric external evaporable free state the formaldehyde chemicals and the manufacture method that absorb.
Formaldehyde is a kind of colourless easily molten irritative gas, and formaldehyde can absorb through respiratory tract, and its aqueous solution can absorb through digestive tract.
Modern scientific research shows that formaldehyde has very big negative effect to health.Abnormal flavour and sense of discomfort when being 0.1 milligram/cubic metre, indoor content are just arranged; 0.5 can stimulate eyes to cause during milligram/cubic meter sheds tears; When reaching 230 milligrams/cubic metre in the air, can cause death at once.
Long-term contact low dosage formaldehyde can cause chronic respiratory tract disease, women's menoxenia, pregnancy syndrome, causes that neonate body constitution reduces, chromosomal abnormality, even causes nasopharyngeal carcinoma.The formaldehyde of high concentration is all toxic to nervous system, immune system, liver etc.But it also exciting eye conjunctiva, respiratory mucosa and producing shed tears, watery nasal discharge, cause conjunctivitis, pharyngolaryngitis, asthma, bronchitis and allergic disease.Formaldehyde also has teratogenesis, carcinogenesis.
Formaldehyde pollution at present mainly is to be discharged by house decorative material and wash-and-wear fabrics.After the house decoration, adopt gravity-flow ventilation to eliminate the influence of formaldehyde, need one or two months usually, in addition finishing finish half a year after indoor formaldehyde still surpass national standard, brought great inconvenience for people's family life.
How eliminating in the evaporable patent of formaldehyde of report comprises Chinese patent 1359992,2451216, United States Patent (USP) 4501628, HOII P 7812336, Russ P 2151630 in early days.Wherein Chinese patent 1359992 has been described and has a kind ofly been eliminated the method for formaldehyde with acetic acid and chitosan, and the efficient that this method is eliminated formaldehyde is low, and owing to use acetic acid, this product has the acetic acid taste when using, and brings new pollution.Chinese patent 2451216 is a utility model patent, utilizes the solid material in the machinery to eliminate formaldehyde.United States Patent (USP) 4501628 has been described and has been adopted ammonia to eliminate the method for formaldehyde emission.HOII P 7812336 has been described a kind of method that adopts albumen to eliminate the excess formaldehyde in the plywood.Russ P 2151630 has been described a kind of method that adopts biodegradable method to eliminate formaldehyde in the air.
The objective of the invention is to propose efficiently a kind of, colorless and odorless, nontoxic liquid chemical preparation is eliminated air, floor, the hazardous substance formaldehyde that furniture etc. exist.This product can spray, and brush to use, also can be in the material surface film forming of volatilization formaldehyde easily, and as at plywood, painted surface forms the protecting film of layer of transparent, and lasting sealing absorbs the formaldehyde that evaporates.And the material that forms behind this product and the formaldehyde generation chemical reaction is that character is highly stable, to the nontoxic material of human body.
The formaldehyde absorbent Main Ingredients and Appearance that the present invention describes comprises that formaldehyde absorbs composition, film former, water, and other auxiliary composition.
The formaldehyde that the present invention adopts absorbs composition, for can with the chemical substance of formaldehyde generation Manny radical reaction (Mannich Reaction), comprise 2-amino-2-methyl propanol, the isobutene. succimide, N-hydroxy-succinamide, 2-amino-5-chlorobenzophenone, the 5-aminolevulinic acid, etc.The preferential 2-amino-2-methyl propanol of selecting.
The film former that the present invention adopts can be, xanthan gum, and sodium alginate, polyvinylpyrrolidones etc. are preferentially selected xanthan gum.
Other auxiliary composition comprises antioxidant, essence.
Using method is with above-mentioned formaldehyde absorbent, is sprayed in the air, perhaps is sprayed on the floor, and treat after the natural drying on the surface of furniture, forms the very thin hyaline membrane of one deck on floor and furniture, the formaldehyde that sealing and absorption come out.In the process of cleaning wash-and-wear fabrics, drip 10 milliliters of these formaldehyde absorbent, soaked 15 minutes, clean up the purpose that can reach place to go formaldehyde.In practical application effect and test, it is remarkable that this formaldehyde absorbent absorbs the formaldehyde effect.
Preparation method is seen embodiment.
Embodiment one:
Under the state of 80 ℃ of heating, 40 gram xanthan gum are added in the 916 gram water, stir dissolving.Be cooled to room temperature, add 40 gram 2-amino-2-methyl propanol and 4 gram ascorbic acid again, stir, can obtain formaldehyde eliminating agent.
Embodiment two:
Under room temperature state, 35 gram polyvinylpyrrolidones are added in the 916 gram water, stir dissolving.Add 45 gram isobutene. succimides and 1 gram essence again, 3 gram ascorbic acid stir, and can obtain formaldehyde eliminating agent.
Claims (2)
1, a kind of formaldehyde absorbent is characterized in that absorbing composition by formaldehyde, film former, and water, and auxiliary composition is formed.
According to the requirement of right 1, it is characterized in that 2, its formaldehyde absorbs composition, for the material of formaldehyde generation Manny radical reaction (Mannich Reaction).
