Abstract
A kind of free phosphate detergent, be characterized in adopting silica xerogel (being precipitated silica) to substitute the main auxiliary agent tripoly phosphate sodium STPP that has now in the washing composition, thereby the phosphorus-containing wastewater of having avoided existing washing composition to produce pollutes " crossing extensive use of chemical fertilizer " that environment causes, and save a large amount of ground phosphate rock, silica xerogel can substitute tripoly phosphate sodium STPP and not reduce washing effect at 1: 2 in washing powder.The production method of washing composition of the present invention is simple, and is with short production cycle, and raw material is easy to get, and low cost product is a kind of comparatively ideal free phosphate detergent.
Description
The invention provides a kind of free phosphate detergent.
Washing composition that generally uses such as washing powder are to adopt tripoly phosphate sodium STPP as main washing auxiliary detergent at present, though it has the effect of washing that helps preferably, but the washes that it caused produces " crossing extensive use of chemical fertilizer " to the discharging waters to be polluted, people once worked out some non-phosphorus washing assistants and made washing powder as substitute tripoly phosphate sodium STPP with 4A molecular sieve (zeolite) for this reason, though it can not produce phosphorus-containing wastewater, but the exchange capacity of itself and calcium ion is lower, then there is not exchange capacity with magnesium ion, thereby can only substitute tripoly phosphate sodium STPP with 1.5: 1, and cost an arm and a leg so far can't industrialization.Recently once the someone proposes a kind ofly to be generated a kind of white meal that mainly is made of sodium aluminate, water glass by reaction and substituted tripoly phosphate sodium STPP as non-phosphorus washing assistant by aluminum oxide or aluminium hydroxide, sodium hydroxide, water glass, but this method need and be controlled certain temperature and time by a few step reactions, technology is complicated, and the production cycle is longer.
The purpose of this invention is to provide a kind ofly easyly be easy to get, cost is lower and washing effect is good free phosphate detergent.
Main points of the present invention are with the tripoly phosphate sodium STPP in the alternative present washing composition of silica xerogel (being precipitated silica), and silica xerogel can substitute tripoly phosphate sodium STPP at 1: 2.Free phosphate detergent composition of the present invention is that polyoxyethylene sodium alkyl sulfate, Xylo-Mucine, Witco 1298 Soft Acid, citric acid and water stir by machinery and closes by silica xerogel, soda ash, sodium sulfate nonionogenic tenside, the white fine particulate material of granulating and forming.The composition range of washing composition of the present invention is (weight %, down together):
Silica xerogel 10-20
Soda ash 18-25
Sodium sulfate 38-48
Nonionogenic tenside 8-13
Polyoxyethylene sodium alkyl sulfate 0-4
Xylo-Mucine 1-2
Witco 1298 Soft Acid (sodium) 0-5
Citric acid 0-4
Water 3-7
Can adopt Witco 1298 Soft Acid or its sodium salt, washing effect is constant.Wherein silica xerogel also can adopt the silica gel that additive method makes to substitute.
For making product of the present invention have whitening effect and having certain fragrance, also can in prescription, add an amount of whitening agent and essence, the former is generally 0.1-0.2% at add-on, and the latter is 0.03-0.05%.
Optimum formula of the present invention is (weight %):
Silica xerogel 15
Soda ash 23
Sodium sulfate 38
Fatty alcohol-polyoxyethylene ether 11
Xylo-Mucine 1
Witco 1298 Soft Acid (sodium) 2
Polyoxyethylene sodium alkyl sulfate 3
Citric acid 2
Whitening agent 0.1
Essence 0.03
Moisture 5
Fatty alcohol-polyoxyethylene ether in the above-mentioned prescription is nonionogenic tenside.
Main preparation flow of the present invention is as follows:
Material metering → machinery stirs and closes → the attached polymer molding granulation → check, packing
Production method of the present invention is at first solid materials to be measured, earlier with silica xerogel, soda ash consumption 1/2nd, the sodium sulfate consumption 1/2nd, Xylo-Mucine, citric acid, whitening agent input stir in the machine of closing, again remaining soda ash, sodium sulfate input are stirred and stir certain hour in the machine of closing, be preferably in about half an hour.And then liquid material measured, and drop in the kneading machine and knead evenly.By certain liquid-solid ratio agglomeration granulation on existing agglomeration granulating and forming machine, can obtain white fine particulate detergent composition at last.
Production method of the present invention is simple, with short production cycle, main detergent builder-the silica xerogel that is adopted is easy to get, thereby product cost is low, be easy to suitability for industrialized production, and silica xerogel can reach 1: 2 and substitute tripoly phosphate sodium STPP in washing powder, and do not reduce washing effect, the present invention has not only avoided the pollution of phosphorus-containing wastewater to environment, but also can save a large amount of ground phosphate rock, simultaneously provide a kind of detergent composition that adopts new washing auxiliary detergent again, its decontamination index reaches the QB510-84 standard.
Enumerate three embodiment below, see following table for details:
The preparation manipulation method of above-mentioned three kinds of proportioning examples as hereinbefore, these three embodiment examination and test of products results show that its decontamination index is respectively 1.47,1.27,1.12, as seen press soil removability the best of example 1 proportioning products obtained therefrom in this three example, example 2, example 3 are taken second place.
