Abstract
A process for preparing a granular detergent composition comprises a first step of preparing a liquid component comprising a structurant. A second step comprises admixture of the liquid with a solid component in a granulator. An optional third step comprises drying and/or cooling. The structurant is incorporated in an amount such that the liquid component is pumpable at temperatures of 50 DEG C or more but causes sufficient solidification to form a free-flowing granulated product.
Description
Invention field
The present invention relates to prepare the method for granular detergent composition or composition by mixing.Specifically a bit say that the present invention relates to the continuous preparation method of the sort of detergent composition.And, the present invention relates to the granular detergent composition that makes with method of the present invention.
Background of invention
In general, the method for preparing washing agent powder has two kinds of main types.First kind, comprise that spraying drying and aqueous washing composition slip place spray-drying tower.Second type method comprises that the dry type of various components is mixed, and randomly adds liquid, and for example the liquid of non-ionic type carries out agglomeration.A kind of method in back is more suitable in the powder of the relative high-bulk-density of preparation.Mainly be because the slip chemical constitution that is used for spray process influences the tap density of particulate product significantly.Have only the content that relatively increases more closely knit sodium sulfate, could increase tap density significantly.But sodium sulfate does not have clean effect, and therefore, the over-all properties that this powder is in the suds has descended.
In the past few years, about producing the mechanical stirring method of high-bulk-density detergent powder, several suggestions appearred.For example, EP-A-265203 discloses the liquid surfactant composition, includes the sodium salt or the sylvite of alkyl benzene sulphonate (ABS) or alkylsurfuric acid, the nonionogenic tenside of ethoxylation and water.The water yield does not exceed 10% (weight percent).Such liquid surfactant composition, may be directed onto on a kind of solid particulate sorbing material, for example be sprayed onto on the powder binder that a kind of porous spraying drying crosses, this base-material has low bulk density, activity is very little, or non-activity, the detergent powder base-material that its result forms has increased tap density.
EP-A-507402 discloses a kind of preparation liquid surfactant method for compositions, and said composition contains a kind of anionic ion type tensio-active agent, a kind of nonionic surface active agent, and the content of water is quite low.The principle of method is to neutralize corresponding to the acid of aniorfic surfactant with strong neutralizing agent, for example, by adding these two kinds of materials in fluid, cause final product to contain the low water content of expectation, this fluid comprises nonionic surface active agent, and it is solvent or thinner as the aniorfic surfactant that has neutralized.This method is to carry out continuously, is preferably in the loop reactor and carries out.
EP-A-420317 discloses a method for preparing granular detergent composition or composition continuously, and composition that this method makes or composition have higher density than what spray-drying process made.Method is formed agglomeration in super mixer by three steps; Multiviscosisty in middling speed granulating thickener makes material be in yielding state; Dry and/or the cooling (for example in thermopnore) of product.In super mixer, the precursor of the liquid acids of anion surfactant is neutralized by the alkaline inorganic material of solid, water soluble (for example yellow soda ash) in position.To small part by sour neutralization reaction heat release, be higher than under 40 ℃ of temperature, obtain the flexible type state of material.
EP-A-544365 discloses a kind of preparation method of particulate composition, and equipment used is identical with the EP-0420317 description, perhaps granulates with batch formula in addition.In this case, the sodium salt of alkylsurfuric acid or sylvite mixture, for example primary alkyl sulfate and oxyalkylated nonionogenic tenside, the liquid phase that is used to granulate in the super mixer.In order to obtain to have the detergent powder of good powder properties, need to control poly-additive process by obvious increase liquid viscosity.For this reason, in the liquid surfactant composition, add one or more compositions.The example that improves the viscosity composition is water and lipid acid and stoichiometric alkaline matter (for example caustic soda), and during the amount of these alkaline matters is enough to and lipid acid, the result forms soap.
The auxiliary agent that for example contains when the powder that will form contains the phosphoric acid salt detergent builder is a tripoly phosphate sodium STPP, and existing blending means just has some shortcomings, is unfavorable for producing that water content is low, the free flowing powder product of good fluidity.These shortcomings, part may be because phosphate builder particle carrier fluid amount is low.The typical problem that runs into comprises owing to what the hydration of heat release and crystal arch formation produced and forms the lump problem.Yet, in last product, tend to form soft particle, because wet particle surface adhesive power is low, grain pattern is poor, powder characteristics deficiency.
A.Naviglio and A.Moriconi (" production of detergents-a kind of new, at a low price, energy-conservation, cooling and drying means "; soap/makeup/chemical characteristic, in September, 1987) a kind of method for preparing granulated detergent with turbine type reactor and rotary drum nodulizer has continuously been described.The dry type neutralization reaction takes place in the turbine type reactor, simultaneously solid [the solid for example: tripoly phosphate sodium STPP, alkaline powder (for example yellow soda ash) of preparing burden therein; Liquid: caustic solution, straight chained alkyl sulfonic acid, lipid acid].Adopt special air diffuser, make powder and liquid keep suspended state, and reach the blended purpose.Use freezing air, to eliminate the heat that discharges in the reaction process.Reactor has a screw, so that be transformed into agglomeration step continuously.In rotary drum, be sprayed onto on water glass or the nonionogenic tenside, for agglomeration creates conditions.This method has been separated neutralization/hydration and agglomeration step.The method that adopts airflow to suspend may stop the formation of hydration tripoly phosphate sodium STPP bulk.Because the low loading capacity of tripoly phosphate sodium STPP, it is inappropriate that the spraying nonionic surface active agent prepares the high detergent powder of activity substance content.
Summary of the invention
Owing to comprise tripoly phosphate sodium STPP or other have low carrier fluid capacity and (or) but problem that the solid of hydration produces now be resolved by new method, method is simpler, adopts the reactor and the mixer apparatus of routine in this area exactly.When other kind solid of processing, its superiority is arranged also.The present invention is made of this method, prepares a kind of liquid component with a kind of constituent, so that under the temperature when this liquid component forms, can aspirate with pump, then at low temperatures, mix, under this temperature, this constituent causes the curing of mixture with a solids component.
International monopoly explanation No.95/32276 discloses a method, and wherein " liquid " composition is deployed into (preferably aqueous) paste, and under 70 ℃, its viscosity is granulated with solids component between the 5-100 pool then.Yet this method not open about utilize phosphate builder and have similar carrier fluid amount and (or) other inorganic salt problem of hydration, so they fail to solve the problem that is solved by the present invention.And they do not provide the convenience that can aspirate this liquid component with pump, do not mention the scheme that makes product that low relatively humidity be arranged yet.For example, method of the present invention also has some beyond thought superiority when using various detergent builder, as making auxiliary agent with zeolite, and the particulate product that makes, it is compared with product up to now, has low relatively humidity.Because humidity is low, follow-up batching can be used percarbonate bleach, and this is from the environment protection angle, and it is better than using perborate.
The particulate product that the result obtains, compressing tablet again is by breaking tenacity (P
Max) and E modulus (E
Mod) measure, this small pieces have very high hardness.These parameters can randomly be used for characterizing the solidified adulterant in the nodulizer.
Like this, on the one hand, the invention provides the method for preparing granular detergent composition, method comprised for three steps, and the first step preparation contains the liquid component of constituent; In second step, liquid component and solids component mix in nodulizer; The 3rd step, randomly dry and (or) cooling; Add an amount of constituent, make liquid component under the temperature of 50 ℃ or higher (for example 60 ℃ or higher), can aspirate with pump, but second and (or) the 3rd step can cause sufficient curing, formed the free flowing granule product.
Second aspect the invention provides composition or composition by the granulated detergent of the inventive method preparation.Detailed description of the preferred embodiments
Particulate product by the inventive method preparation can be considered to free-pouring, and (DFR) is preferably more than 90mL/S if it has dynamic flow velocity.Normally, dynamic flow rate can be measured like this, allows the flow of powder of known volume cross one and is with graduated metering-orifice and pipe.Powder through the time between two photosensors by record automatically, calculate dynamic flow rate by the volume that flows through and the flowing time of record.
By the granular detergent composition of the inventive method preparation, may be final product form, can directly sell the human consumer.They also may mix with other ingredient composition as powder binder or additive again.No matter what situation, the tap density of this granular detergent composition may be 550g/L.Preferred, minimum is 650g/L.But these products productions come out, and also may be low bulk densities.
The preferred embodiment of the inventive method and composition can characterize with intensity and the E-modulus measured, and tested sample is taken from: (a) Tableted compositions of being produced by this law; And/or (b) compressing tablet that forms of liquid component cooled and solidified.
Intensity (hardness) can be measured with Instron pressure instrument.Pressed powder can carry out in punch press and pressing mold, and acting on the lip-deep peak pressure of compressing tablet is 10 tons, the compressing tablet diameter 9mm of formation, high 16mm.For the curing that obtains with present method liquid component, its contact solids component before, the diameter of compressing tablet is 14mm, high 19mm.
Small pieces (powder or liquid component) place between a retaining plate and the maneuvering board destroyed.The speed of maneuvering board is transferred to 5mm/min, and the Measuring Time that it causes is about 2 seconds.The pressure curve record on computers.Obtain peak pressure (pressure when small pieces are broken) like this, calculate the E-modulus by rate of curve.
For particulate product, P
MaxMinimum value, preferably 0.5MPa, most preferably 2MPa; E
ModThe minimum value of (E-modulus), 20MPa preferably, and 50MPa most preferably.Yet, for the liquid that has solidified, 20 ℃ the time, preferred P

Liquid component preferably prepares in shearing dynamic mixer, and these compositions are carried out pre-mixing, simultaneously in and the precursor of anionic acid.Dynamic mixer preferably places on the loop that heat exchanger is housed, to eliminate the heat that neutralization reaction discharges.
In introducing upper and lower literary composition of the present invention, " Structurant " is meant any one composition, and liquid component is solidified, and therefore can granulate well, even under the very low situation of solids component carrier fluid amount.
" Structurant " may classify as like this some materials, and they are considered to implement its structure (curing) effect, a kind of during mechanism of action subordinate is listed as several: recrystallization (for example silicate or phosphoric acid salt); Create thin solid particulate network (for example silicon-dioxide or clay); And on molecular level to the influential material of steric effect (for example soap or polymkeric substance), as usually as the material of detergent builder.One or more constituents may be used.
Soap is being represented a class preferred construction composition, especially when liquid component includes liquid nonionic type tensio-active agent.In many cases, the mean chain length of expectation soap is greater than the chain length of liquid nonionic type tensio-active agent, but less than the twice of latter's mean chain length.
If necessary.Solids component may be dissolved in or be scattered in the liquid component.The content of the routine of main component is as follows in the liquid composition:
Preferably, liquid nonionic type tensio-active agent, the weight ratio that accounts for substantial liquid component is 10% to 98%, more preferably is to account for 30% to 70% of weight ratio, and is particularly preferred, is to account for weight ratio 40% to 50%; Aniorfic surfactant preferably accounts for weight ratio 98% to 10%, more preferably accounts for weight ratio 70% to 30%, particularly preferably is to account for weight ratio 50% to 40%.The total amount of constituent preferably accounts for 2% to 30% of liquid composition weight percent, and preferred weight percent 5% to 20% or 5% to 15% of accounting for is particularly preferred, accounts for weight percent 10% to 15%.In general, liquid composition best (though not being hard and fast rule) contains some liquid nonionic type tensio-active agents at least.Available other organic solvent replaces liquid nonionic type tensio-active agent, or both share but generally speaking.
Liquid component should be in fact non-water preferably.That is to say that wherein the weight percent of aqueous total amount is no more than 15% of liquid phase, preferably be no more than 10%, generalized case is 5% to 8%, particularly 6% to 7%.
Generally speaking, 3% to 4% the water that accounts for liquid composition weight is the by product of reaction, and remaining water is the solvent of alkaline matter.Wish that very except the solvent as alkaline matter, liquid composition is anhydrous, perhaps just the water of trace exists as impurity.
Wish very much, the reaction of precursor and basic material by suitable acid, as alkali metal hydroxide, for example reaction of NaOH, some or all aniorfic surfactant of formation in liquid composition on the spot.Because the latter must be made into the aqueous solution usually, so will introduce some water inevitably.And the reaction of alkali metal hydroxide and acid precursor also generates some water as by product.
Though any basic metal inorganic materials can be as the usefulness of neutralization, the water-soluble alkaline inorganic materials is preferred.Another kind of preferable material is a yellow soda ash, it can use separately, also can be used in combination with one or more water-soluble inorganic materials, for example is used in combination with sodium bicarbonate or water glass.Yellow soda ash as mentioned above can provide necessary alkalescence to washing process, and in addition, it can also be as the auxiliary agent of washing composition.In the case, the present invention as unique or main auxiliary agent, is a superiority with yellow soda ash when preparing washing agent powder.Therefore, the carbonate of adding is than needed more more significantly in order to the acid anion surfactant precursor that neutralizes.
Liquid component randomly includes the dissolved solid and/or is scattered in solid particulate in small, broken bits in the liquid phase.Unique restriction is to have dissolved or dispersed solids material, and under 50 ℃ or higher temperature, liquid component should be able to aspirate with pump, perhaps under 60 ℃ or higher temperature, for example 75 ℃, should be able to aspirate with any speed.Preferably, be lower than under 50 ℃ of temperature, it is a solid, and preferably at 25 ℃ or more under the low temperature, it is a solid.In general, under the shear rate that pump is taken out, the viscosity of the liquid component that available pump is taken out is not more than 1 pool.
In mixing tank, constituent causes curing, preferably produces adulterant and small pieces, and intensity as previously mentioned.Generally, the temperature during granulation is higher than 10 ℃, preferably is higher than 20 ℃, but will be lower than certain temperature, and under this temperature, adulterant is produced, and with in the pump suction nodulizer.
If solids component includes phosphate builder, perhaps form by it basically, when solids component and liquid component being put together when mixing, liquid component is from 0.25: 1 to 0.5: 1 to the ratio of solids component.If solids component includes the aluminosilicate auxiliary agent, perhaps to form by it basically, this ratio is preferably from 0.4: 1 to 0.7: 1.

About the used equipment of the mix stages of preparation process (be liquid component with solids component mixes after), the same solid component mixing of liquid component, preferably in super mixer/density degree device, carry out, form the granulated detergent material at first mixing step.
Randomly,, may then carry out for second step and mix, in a middling speed pellet fabrication device/density degree device, carry out from the granulated detergent material that first mixing step obtains.High-bulk-density product if desired, in this stage, it can be made into or remain on needed flexible type state.Under any circumstance, the product of first mixing step or second mixing step can be cooled and/or drying then.
At the first step mixing step, preferably 5 to the 30 seconds residence time in super mixer/density degree device.At any second (randomly) mixing step, rest on the interior time of moderate-speed mixers/thickener preferably from about 1 to 10 minute.Implement present method, continuous mode preferably, but also may be by high shear rate or low shear rate model, batch formula is carried out.
At first mixing step, the solids component of raw material with the method for super mixer/density degree device, thoroughly mixes with liquid dispensing.Such mixing tank provides high-octane power of agitator, in a short period of time, reaches completely and mixes.
About super mixer/density degree device, we preferentially adopt Lodige (trade mark) CB30 circulator.This device is mainly big by one, and the fixed hollow garden post of diameter 30cm is formed horizontal positioned.Therein, a rotation axis is arranged, dissimilar blades is housed above.Its rotating speed 100 and 2500rpm between, the consistency of raw material and the particulate size of expectation are depended in the selection of rotating speed.The effect of axle blade is to make to reach sufficient mixing at this stage blended solid and liquid.The average residence time is depended on the position of rotating speed, blade and the spillway of axle a bit.The super mixer that suitable effect is arranged in detergent powder production of other type/density degree device also can be hopeful to be used.For example, Shugi (trade mark) nodulizer or Drais (trade mark) K-TTP 80 may be used.
At first mixing step, material composition is in super mixer/density degree device, and in the quite short time, about 5-30 second, by thoroughly evenly, preferred condition is that raw material becomes or remains on the yielding state that limits later.
Under the situation of producing the high-bulk-density product, behind first mixing step, if the Betengent product that obtains remains suitable porous, do not select this product is kept the long period in super mixer/density degree device, improve tap density, and can be randomly through second mixing step, the washing composition material was handled 1-10 minute in a moderate-speed mixers/density degree device again, preferably 2 to 5 minutes.In this second procedure of processing, grasp such condition, powder is become, or maintain the deformable state.As a result, the particle hole will further reduce.The main difference of this step with the first step is that mixing velocity is low, the retention time in mixing tank long (1-10 branch), and this is a conditions needed to making powder become deformable.
The second optional mixing step can successfully carry out in Lodige (trade mark) KM300 mixing tank (also claiming Lodige Poughshare).This device mainly is made up of the fixedly garden post of a hollow, and individual rotation axis is arranged in the middle of it.On the axle plow-shape blade is installed.The velocity of rotation of rotating shaft is 40-160rmp.Randomly, adopt one or several fly-cutter, prevent too much caking.Another suitable machine of this step usefulness is that for example Drais (trade mark) K-T 160.
Yet, not with high-speed mixing density degree machine, next use isolating middling speed caballing degree machine again, but, divide two kinds of speed operations with a machine, can obtain identical effect.At first use at a high speed,, then use middling speed, reach the purpose of granulation/density degree in order to mix/the density degree.Suitable machine comprises Fukae
FS-G series; The Diosna of Germany Dierks and Sohne company
V series; The Pharma Matrix of Britain T.K.Fielder company limited
The Fuji of Japan Fuji Sangyo company
VG-C series; The Roto of Italy Zanchetta and Co.Srl
, and Schugi
The Flexomix granulator.
For the ease of using, to handle and store, the detergent powder of density must be in free-flowing.Therefore, if necessary, in the end a step, powder can be dried or cool off.This step can carry out with known method, for example, (dry, cooling) on the thermopnore device or in an air elevator (cooling) carry out.If powder only needs to cool off this step, just more favourable, because the machine that needs is just simple relatively with more economically like this.
In order to produce the product of high-bulk-density, at any second optional mixing step, and preferably also at first mixing step, detergent powder should become yielding state, so that obtain best density effect.Super mixer/density degree device and/or the close device of middling speed pellet fabrication device/thickening can make particulate material distortion effectively, and its method is that the particulate porosity is obviously reduced, or remain on low-levelly, and the result has increased tap density.
By the detail description example, the present invention is carried out more detailed explanation.
