Abstract

The non-phosphorus disinfecting wash powder is prepared from non-ionic surfactant, sodium polyacrylate, sodium carbonate, dicarbonate, pentahydrated sodium metasilicate, sodium sulfate, hibitane, deionized water and esence through mixing and features no environmental pollution, high detergency, high disinfecting effect, and no crrosion to metal ware.

Description

Sterilizing phosphorous-free washing powder and its prodn. method

The present invention relates to a kind of sterilization, non-phosphide detergent and preparation method thereof.

At present, the washing powder of domestic production is mostly allocated the phosphoric acid salt of higher proportion into, so washes has caused river course, lake water eutrophication after discharging, has greatly influenced vegeto-animal growth in the water, has destroyed ecotope.National environmental protection department was once detected the river in Beijing, two cities, Guangzhou, found that its eutrophication degree is quite serious.Fa Da American-European countries expressly provides already and limit or ban use of phosphoric acid salt in the synthesis of detergent product in the world, and substituting with non-phosphide detergent has phosphorus washing powder, and this is a developing direction.In addition, if in washing process, can kill bacterium on the clothing, virus then more can be subjected to human consumer's welcome, reduce people to patient's clothing disinfectant trouble and difficulty.The disinfectant detergent powder of selling mostly is the product of chloride or doped quaternary ammonium salt on the existing market, its hypochlorous acid smell of the disinfectant detergent powder of chlorine-containing agent people that chokes very much, and pungency is big, and flushing is totally serious to the clothing damage; Contain the disinfectant detergent powder of quaternary amine, sterilisation effect is poor, and the somebody has allergic phenomena after using, and the effect of decontamination contaminant releasing is good inadequately.

The objective of the invention is to improve the shortcoming of prior art and a kind of without phosphorus, nontoxic, free from extraneous odour is provided, non-stimulated to human body, to the strong washing powder of the undamaged pollution-removing disinfecting ability of fabric.

The object of the present invention is achieved like this, selects following composition and weight percent thereof for use

Nonionogenic tenside 8-15%

Molecular weight is 2,000,000-5,000,000 0.8-1.2%

Sodium polyacrylate (or CMC and EDTA)

Yellow soda ash 10-30%

Tubulicid 0.2-2%

Sodium bicarbonate 5-15%

Deionized water 4-6%

Metasilicate pentahydrate sodium 5-20%

Sodium sulfate 20-50%

Essence is an amount of

Wherein, Tubulicid is a disinfection sanitizer, and traditional view thinks that it can not use (the 47th page of practical Disinfection with the washing powder compatibility, the People's Medical Officer Press publishes), the solubleness of Tubulicid in water is 1.9%, and the sterilization rate of its aqueous solution is 43.4%, the present invention's one confrontational notion, use Tubulicid to make disinfectant detergent powder, in the present invention's prescription, its water solubility is brought up to more than 30%, and sterilization rate reaches 99.99%.Nonionogenic tenside is selected polyoxyethylene nonylphenol ether (Tx-10) for use or with the mixture of polyoxyethylene nonylphenol ether and fatty alcohol-polyoxyethylene ether (AEO9), Tx-10 in its mixture: AEO9=1: 08-1, it is the main component of washing for (weight ratio): yellow soda ash, sodium bicarbonate work the effect of washing that helps, and improve detersive power; Starso suspends spot, leaves fabric; Sodium polyacrylate (molecular weight is 2,000,000)-5,000,000 reduces water hardness, and throwing out arranged, its available EDTA(Calcium Disodium Versenate salt) and the CMC(Xylo-Mucine) substitute, EDTA: CMC=1: the 1(weight ratio) but EDTA complexing calcium, magnesium ion, reduce water hardness, CMC can prevent that spot from depositing again; Sodium sulfate (Sodium sulfate anhydrous.min(99)) can reduce the pH value of solution, helps clarification, helps and wash, and the synergistic effect of various compositions makes this product in this prescription in a word, and promptly sterilization and disinfection is effective, and the decontamination contaminant releasing ability is strong again.

Its preparation method is that at first nonionogenic tenside and the deionized water mixing that 45-55% is measured is heated to 50 ℃-130 ℃, adds Tubulicid and fully stirs postcooling to 40 ℃-50 ℃ of heat preservation for standby use; Secondly, the sodium polyacrylate (perhaps carboxymethyl cellulose and Calcium Disodium Versenate salt) and the nonionogenic tenside of surplus are stirred, be warmed to 40 ℃-50 ℃, usefulness such as insulation; Again, admittedly expect yellow soda ash, sodium bicarbonate with all the other all, sodium sulfate, metasilicate pentahydrate sodium mix, at last nonionogenic tenside, deionized water, Tubulicid mixed solution and sodium polyacrylate (perhaps carboxymethyl cellulose and Calcium Disodium Versenate salt), nonionogenic tenside stirs liquid and mixes, and is sprayed on the solid material, and essence in the mixing (can not adding as non-civil goods) is product of the present invention.

Product of the present invention gives anti-Academy of Medical Sciences environmental health and sanitary engineering institute detection proof through China, nontoxic, to eyes and skin nonirritant, no mutagenesis, no cumulative toxicity effect, so but life-time service and harmless is washed the tool non-corrosiveness to metal, be suitability disinfecting cleaning articles for use (annex 1) extensively and safely and effectively, proof detects in the Beijing Inst. of Textile Science, and product of the present invention is to not influence of fabric, and the influence of colour fastness is met national standard (annex 2); Shoudu Inst. of Pediatrics uses proof, the bacterium product wash degree height that originally disappears, and to the clothing non-corrosiveness, free from extraneous odour is to the killing effect obvious (annex 3) of bacterium.
