The present invention relates to a non-phosphorus detergent and a preparation method thereof. The detergent comprises the components of the following weight percentage: 3 to 5% of fatty alcohol-polyoxyethylene ether, 18 to 20% of sodium dodecylbenzene sulfonate, 10 to 14% of anhydrous sodium metasilicate, 13.5 to 16.5% of sodium bicarbonate, 14.5 to 17.5% of sodium carbonate, 0.5 to 2% of a copolymer of maleic acid and acrylic acid, 20 to 24.5% of sodium sulfate, 1.7 to 2.7% of sodium carboxymethylcellulose, 0 to 1% of an additional additive and 5% of water. When the detergent is prepared, the preparation method comprises: firstly dissolving the fatty alcohol-polyoxyethylene ether and the sodium dodecylbenzene sulfonate or sulfonic acid into the water uniformly; then orderly adding the copolymer of maleic acid and acrylic acid or sodium edetate, the sodium carbonate, the sodium sulfate and the sodium carboxymethylcellulose into a solution; drying after the solution is uniformly mixed and preparing the mixture into granular; finally mixing the mixture with the anhydrous sodium metasilicate and the sodium bicarbonate uniformly.
Description
What the present invention relates to is a kind of free phosphate detergent, particularly a kind of non-phosphide detergent, and preparation method thereof.
For solving the conventional washing agent, can cause water surrounding " eutrophication " as the tripoly phosphate sodium STPP in the washing powder commonly used after with the washes discharging, and a series of problem of environmental pollutions that caused, the free phosphate detergent that replaces tripoly phosphate sodium STPP with other proper composition is being studied widely and is being used.As replacing tripoly phosphate sodium STPP, every scourability of conventional washing agent is not subjected to or few affected alternative auxiliary agent, that uses at present mainly contains kind surplus 4A zeolite, Trisodium Citrate, compound sodium disilicate, metasilicate pentahydrate sodium, the anhydrous sodium metasilicate etc. ten.Wherein be preferably anhydrous sodium metasilicate aspect the comprehensive price ratios such as pH value, soil release characteristics, perviousness, dispersiveness, emulsifying property, rinsing, stability in hard water, acid resistance, active alkali and bactericidal properties.
Given this, the purpose of this invention is to provide a kind of free phosphate detergent, particularly a kind of non-phosphide detergent, and the preparation method of this washing composition with anhydrous sodium metasilicate replacement tripoly phosphate sodium STPP.
Free phosphate detergent of the present invention is in the tripoly phosphate sodium STPP, to cooperate interpolation can remedy anhydrous sodium metasilicate again and form jointly at insufficient maleic acid-acrylic acid copolymer (PAA) aspect the anti-performance of hard water or tetrasodium ethylenediamine tetraacetate (EDTA-4Na) composition in the agent of anhydrous sodium metasilicate replacement conventional washing.The weight of the said free phosphate detergent of the present invention is formed (%):
Fatty alcohol-polyoxyethylene ether 3-5
Sodium dodecylbenzene sulfonate 18-20
Anhydrous sodium metasilicate 10-14
Sodium bicarbonate 13.5-16.5
Yellow soda ash 14.5-17.5
Maleic acid-acrylic acid copolymer (PAA) 0.5-2
Sodium sulfate 20-24.5
Xylo-Mucine 1.7-2.7
Additional additives 0-1
Water 5.
Wherein particularly form (%) for well with following weight:
Fatty alcohol-polyoxyethylene ether 3-5
Sodium dodecylbenzene sulfonate 18-20
Anhydrous sodium metasilicate 10-14
Sodium bicarbonate 13.5-16.5
Yellow soda ash 14.5-17.5
Maleic acid-acrylic acid copolymer (PAA) 1.5-2
Sodium sulfate 20-24.5
Xylo-Mucine 1.7-2.7
Additional additives 0-1
Water 5.
Said maleic acid-acrylic acid copolymer can use tetrasodium ethylenediamine tetraacetate (EDTA-4Na) to replace in the above-mentioned composition.Washing composition weight after replacing with tetrasodium ethylenediamine tetraacetate form (%) can for:
Fatty alcohol-polyoxyethylene ether 3-5
Sodium dodecylbenzene sulfonate 18-20
Anhydrous sodium metasilicate 10-14
Sodium bicarbonate 13.5-16.5
Yellow soda ash 14.5-17.5
Tetrasodium ethylenediamine tetraacetate 0.5-0.7
Sodium sulfate 21.3-22.5
Xylo-Mucine 1.7-2.7
Additional additives 0-1
Water 5.
In above-mentioned free phosphate detergent, said Sodium dodecylbenzene sulfonate can also be replaced with sulfonic acid in the composition.When producing washing powder, said anhydrous sodium metasilicate serves as better to adopt granular feedstock in the composition, because of it need not granulation again with respect to Powdered anhydrous sodium metasilicate when producing washing powder, can prepare the back, can reduce production link and save energy, have bigger superiority.In addition, said additional additives in the composition, can be generally that white dyes, spices and tinting material etc. select for use as required in washing composition commonly used but nonessential additivity composition, so these compositions can use or not use as required.
The preparation method of the above-mentioned described free phosphate detergent of the present invention is, fatty alcohol-polyoxyethylene ether in the said raw material, Sodium dodecylbenzene sulfonate or sulfonic acid is evenly soluble in water, after again maleic acid-acrylic acid copolymer or tetrasodium ethylenediamine tetraacetate, yellow soda ash, sodium sulfate and Xylo-Mucine being added this solution successively and mixing, dry also make the powder shape, add anhydrous sodium metasilicate then, sodium bicarbonate mixes.In the preparation process, can also make appropriate selection to concrete operations mode wherein according to practical situation or needs.For example when preparation washing powder, when having spray-dired equipment and condition, after the weight concentration of the material solution behind the said uniform mixing can being adjusted into the slip of 55%-60%, nozzle by diameter～3 millimeter is 81 ℃-85 ℃ in 40-70 bar pressure and its inlet temperature, temperature out is to carry out spraying drying under 170 ℃-185 ℃ the condition, and powder granular products is chilled to the married operation that descends the step behind the normal temperature; Do not possess or when not wishing to carry out spraying drying, also the material solution behind the said uniform mixing can be dried the back and pulverize under 80 ℃ of-90 ℃ of temperature, and granularity is sieved on request, then the married operation that goes on foot down.In addition, when needs use as during selectable additivity added ingredients such as white dyes, spices and tinting material, solutions employed is the aqueous solution that is dissolved with white dyes and tinting material in advance in the time of can making the preparation of said each material solution; Fragrance component in the raw material then with the mixing step of powder granular products in add.The raw material sources that are appreciated that the above-mentioned washing composition of the present invention thus are extensive, and the preparation method is simple, and with needing extensive and stronger adaptability can both be arranged to different working conditions.
Below by being that the specific embodiment of representative is described in further detail foregoing of the present invention with washing powder.But this should be interpreted as that the scope of the above-mentioned theme of the present invention only limits to following example.
The weight % of each routine washing powder table composed as follows:
