Abstract
The present invention relates to a technology for preparing natural green soap powder by a cold method and a product thereof. The technology comprises the following steps: adding molten alcohol amide into raw oil sediment waste material at a normal temperature and a normal pressure; orderly adding sodium silicate and sodium hydroxide solution during stirring to carry out saponification; adding sodium carbonate to replenish saponification; uniformly stirring and slowly adding hydrogen peroxide to carry out bleaching and decolorization; orderly adding betaine, inorganic sodium salt and starch; drying and sieving to obtain a finished product after thorough and uniform mixing. The technology for preparing natural green soap powder by a cold method of the present invention makes use of the exothermic reaction of oil sediment and additives to complete saponification, so the technology has no need of soap boiling, alkali out or salting out, no three waste discharge and short reaction time. The product prepared by the technology of the present invention has good dispersivity, strong hard water resistance, no calcium soap generation, good biodegradation, and good applicability to both cold water and hot water.
Description
The present invention relates to daily chemical product, cold process preparation technology of particularly a kind of natural green soap powder and products thereof.
Existing soap powder is that raw material makes through saponification with animal oil or chemical industry oil generally, raw materials cost height not only, and need main equipments such as fluidized-bed, spraying, the production cycle of product is also longer, generally will be more than 10 hours.It is 87105105.2 application for a patent for invention that Patent Office of the People's Republic of China discloses application number on June 7th, 1989, providing a kind of is raw material is analysed preparation through twice saponification, twice alkali laundry powdered soap with the oiliness waste material behind the vegetable oil and fat refining, the used raw material of this technology is to still have the oiliness waste material of further putting forward the oil price value after the vegetable oil mill refining, and the preparation method of soap powder analyses and tablet forming technique for traditional repeatedly saponification, alkali, the production cycle of product needs about 60 hours approximately, and the talcum powder in the used subsidiary material is a water-insoluble, need consume a large amount of caustic soda simultaneously.In addition Patent Office of the People's Republic of China to disclose application number on December 28th, 1994 be 93107371.5; name is called natural phospholipid soap powder and the quick preparation technology's of single stage method thereof application for a patent for invention; though this technology has solved the problem of making soap powder fast; but do not solve discharge of wastewater problem in the soapmaking process; more and more pay attention to today of environment protection people, its process implementing is restricted.
The objective of the invention is to overcome in the prior art soap base decolouring bleaching difficulty, calcium soap bad dispersibility, blowdown can't solve and can not adapt to deficiency such as big production needs of continuity, is the cold process preparation technology of the natural green soap powder of raw material with the vegetable oil residue and provide a kind of.
Another object of the present invention provides a kind of product that adopts above-mentioned preparation technology to make.
The cold process preparation technology of natural green soap powder of the present invention comprises under normal temperature, the normal pressure, in raw material oil foot waste material, add alkylolamide, stir, continuation adds water glass successively under stirring condition and sodium hydroxide solution carries out saponification, add the yellow soda ash solid again and replenish saponification, stir the back an amount of hydrogen peroxide of slow adding and carry out bleaching, and then adding trimethyl-glycine, inorganic sodium and starch successively in the material after bleaching, thorough mixing evenly back drying, screening can obtain finished product.
Wherein, described raw material can also be an oleic acid.
Described alkylolamide can be single ethanol amide, quadrol or trolamine; Add-on is the 10-12% of raw material weight.
Described water glass is a catalyzer, and add-on is 6-8%.
The concentration of described sodium hydroxide solution is 30-38 ° of Be, and the solution add-on is the 10-15% of raw material weight.
Described yellow soda ash solid add-on is the 20-25% of raw material weight.
The concentration of described hydrogen peroxide is 27.5%-30%, and add-on is white in color fully with reactant and is as the criterion.
The add-on of described trimethyl-glycine is the 3-5% of raw material weight, mainly is used as dispersion agent and antistatic, foam enhancing auxiliary agent.
Described inorganic sodium can be yellow soda ash, sodium bicarbonate, sodium sulfate or water glass; Add-on is the 10-30% of raw material weight.
The dust removal of described starch is effective, and to the human body nonirritant, add-on is the 5-10% of raw material weight.
Among the preparation method of the present invention, the total reaction time of described adding alkylolamide, saponification and bleaching process is 20-60 minute.
Can also comprise among the preparation method of the present invention that product after the screening is carried out perfuming to be handled.
Contain alkylolamide, sodium soap, glycerine, trimethyl-glycine, starch, inorganic sodium and moisture in the natural green soap powder that adopts preparation technology of the present invention to make.
The cold process preparation technology of natural green soap powder of the present invention has changed traditional soap preparing process, utilized the thermopositive reaction of oil foot and additive to finish saponification, therefore need not soap boiling, alkali is analysed and saltout, three-waste free discharge, reaction times is short, finish continuously from being dosed into finished product, and be suitable for animal-plant oil and the greasy soap powder production of chemical industry equally.
The good product dispersibility that adopts preparation technology of the present invention to make, stability in hard water are strong especially, and no calcium soap produces, and biological degradation is good, and the hot water or cold water all is suitable for, moderate foam, and strong detergency, and without phosphorus, no benzene, thereby do not have any toxicity, side effect.
Further describe the present invention below in conjunction with embodiment
