Description

A kind of washing powder not containing zeolite and phosphorus

The present invention relates to washing composition, more specifically relate to a kind of do not have zeolite, without phosphorus environment-protection detergent powder.

Both at home and abroad to the environmental issue pay attention to day by day, a lot of American-European countries have prohibited phosphorus at present, and areas such as China's Coastal Areas and Dian Chi, Chaohu, Taihu Lake, river Han basin have implemented to prohibit phosphorus.Washing composition major part on the domestic market is phosphorous now, and phosphorous washing powder not only destroys water quality but also contain carcinogens.China's washing powder is produced about 2,000,000 tons of total amounts per year, calculate with average 15% phosphate content, there are every year 300000 tons of P contained compounds to be discharged in the surface water approximately, because of phosphorous too much, China lake nearly all is in the rich state of supporting at present, because a large amount of phosphorous washess enter rivers and lakes, destroy water quality, produce threat to environmental quality.

Environment-protection detergent powder is to replace tripoly phosphate sodium STPP (five sodium) to produce non-phosphide detergent with the 4A zeolite substantially at present.European patent by retrieval, the patent No. is 356974 (1990), technical scheme is: 4A zeolite 22.7kg, N, N-two sodium-acetate alanine sodium 9kg, Sodium dodecylbenzene sulfonate 5.7kg, Sodium peroxoborate 18.2kg, two Magnesium Silicate q-agent 0.9kg, carboxymethyl cellulose 0.55kg, yellow soda ash 10.9kg, sodium-chlor 2.5kg, fatty alcohol-polyoxyethylene ether 4.3kg, sodium disilicate 5.45kg, sodium sulfate 19.8kg.Chinese patent CN 1232867A, " a kind of non-phosphide detergent and preparation method thereof ", its technical scheme is: sodium laurylsulfonate 15-40 part, yellow soda ash 40-80 part, carboxymethyl cellulose 1-10 part, sodium sulfate 120-180 part, bubble flower alkali 110-140 part, Phenylsulfonic acid 4-35 part, fluorescence white flushing agent 0.5-1 part, Sumizyme MP 0.5-4 part, essence 0.3-0.5 part, sodium lauryl sulfate 0-8 part, fatty acid alkyl alcohol amide 0-5 part, ethoxylated dodecyl alcohol 0-3 part.Another technical scheme is: promoting agent 18%, 4A zeolite 3%, MR3%, alkali 10%, water glass 12%, VBL0.1%, process water 5%, saltcake (surplus is assigned to 100%).More than the effect of three kinds of softening waters undesirable, and water insoluble.On technology, the main mode that the eighties China produces washing powder is the high tower spraying, and the main mode in the nineties later stage is an agglomeration granulation mode.But two kinds of methods all have its shortcoming: so far, be on technology, satisfy twenty Pius XI on the prescription and record to three requirements greatly of washing powder: environmental protection is without phosphorus; Investment in fixed assets is few; Aspects such as comprehensive cost is low also are nowhere near.Existing problem concentrates on several aspects: 1, replace phosphoric acid salt with the 4A zeolite and exist cost height (than the phosphorus powder height is arranged) and water insoluble.2, the investment of agglomeration prilling process is high, and product is not expanded.3, high tower mode energy consumption is big, invests relatively also bigger.4, functional structure and the combination and compatibility in the prescription is unreasonable.

The purpose of this invention is to provide a kind of no zeolite, non-phosphide detergent, adopted tween to replace anion active agent, reduced susceptibility hard water to the hard water good stability, prescription is reasonable, and technology is easy, and cost is low, the washing clothes strong detergency is to water body and body harmless.

The objective of the invention is to realize by following technical measures:

Prescription of the present invention does not adopt the 4A zeolite to replace five sodium softening waters, but improves formulation composition according to function, makes various raw materials that a kind of rational compatibility be arranged.Reduce the usage quantity of the promoting agent (as Sodium dodecylbenzene sulfonate) of being afraid of hard water on the one hand, and increase some hard water there is stable tween, as fatty alcohol-polyoxyethylene ether, coconut oil diethanol amide, alkylphenol polyoxyethylene, increased the usage quantity of auxiliary agents such as yellow soda ash that the softening water function is arranged and water glass on the other hand, thereby broken away from dependency this sequestrant of five sodium.Its prescription is as follows:

Fatty alcohol-polyoxyethylene ether 3-4%

Polyoxyethylenated alcohol sodium sulfate 2-5%

Alkylphenol polyoxyethylene 3-4%

Coconut oil diethanol amide 2-4%

Sodium dodecylbenzene sulfonate 2.5-3.5%

Soda ash 18-20%

Water glass 6-12%

Carboxymethyl cellulose 2%

Sodium sulfate anhydrous.min(99) 35-55%

Whitening agent 0.1-0.3%

SPC-D 6-10%

Sumizyme MP 0.2%

Essence 0.2%

With above-mentioned preceding four kinds of raw materials heating, temperature is controlled at 50-60 ℃, be easy to mix, then these liquid starting materials and other powder raw material are evenly fallen in proportion feeding mouth, temperature is controlled at 148-152 ℃, go out the first road product after stirring agglomeration, SPC-D and essence and the first road product are carried out static uniform mixing after again, just obtain a kind of washing powder of not containing zeolite and phosphorus.

The present invention compared with prior art has the following advantages and effect, and technology is easy, and cost is low, and consumption is few, the washing clothes strong detergency, and speed is fast, and to water body and body harmless, it is glossy, soft, comfortable to wash the back clothing.
