Description

Form the method for agglomerated particle
The field
The present invention relates to form the method for agglomerated particle, specifically, the present invention relates to form the method for the agglomerated particle that contains polymkeric substance.
Background
Agglomerated particle in cleaning composition, the especially agglomerated particle in laundry composition will contain the acidic substance that exist in process of production usually.For example, production process can be used the acid activity form of anion surfactant, and it is neutralized in process of production.And the tensio-active agent that some anion surfactant can be used as pre-neutralization in some occasion adds, the tensio-active agent of this pre-neutralization can be unavailable, and quality is insecure or undue costliness, therefore, typical production process adds the acid activity material, therein with its neutralization.
Some material, for example polymkeric substance adds in the agglomerated particle usually so that soil dispersion character, antiredeposition character, fabric-conditioning character etc. to be provided.In addition, some high-melting-point liquid comprises that some polymkeric substance, tensio-active agent soup compound, suds booster etc. also can add in the agglomerated particle so that additional required character to be provided, and for example washs character, brightens character, foam levels adjusting etc.And the kind of polymkeric substance and high-melting-point polymer is overlapping, does not have one group to be other complete subgroup.Therefore, any or their combination can be present in the agglomerated particle.One type the polymkeric substance that is particularly useful for agglomerated particle is a modified polyamine polymers, and this modified polyamine polymers provides one or more required as discussed above character usually.Specifically, this modified polyamine polymers can for example provide soil dispersion, antiredeposition and the fabric-conditioning character of improvement, and the polyamine polymer of modification can contain and for example is connected in the additional charged of polymer backbone or charged group not.
Agglomeration process produces agglomerated particle, and it contains many concentric layers, is similar to onion.Common polymkeric substance can add in the agglomeration process or when agglomeration process finishes with the acid activity material and add with liquid vehicle.These methods obtain the uniform distribution of polymkeric substance in the different layers of whole " onion " respectively, or polymkeric substance is concentrated in the extexine of " onion ".
The required character of these polymkeric substance depends on the character of their molecular weight and coupled any modification group usually.Above-mentioned character is normally with concentration dependent, and the concentration of polymkeric substance is big more, and effect is big more.Yet, this polymkeric substance, especially modified polyamine polymers, it produces normally expensive.Therefore, they use with quite low concentration usually.Therefore, need to add the polymkeric substance of effective concentration, also keep the sufficiently low formulation cost of this concentration with increase cleaning composition within reason.
The particle cleaning composition that contains high-melting-point liquid lumps or agglomeration in storage process usually easily, and no matter from the still reason of performance attractive in appearance, the particle of this caking is undesirable.For example compare with free flowing granule, agglomerated grain needs the long time to dissolve usually.Dissolving or incomplete dissolved particle also can not left over unwanted film or remnants on the dirt-carrying body.
Therefore, people still need a kind of polymkeric substance is not increased formulation cost to keep polymer property, unrestricted flow character and performance profile concentration to add the method for agglomerated particle, also need high-melting-point liquid added agglomerated particle and keep the method for acceptable unrestricted flow character simultaneously.
General introduction
We find now the acid activity material that exists some polymkeric substance of can degrading in agglomeration process, cause them to be decomposed into the fragment of lower molecular weight, and they are providing obviously not too effective aspect the required polymer property.Therefore this polymkeric substance is called " acid-sensitive sensitive polymeric " in this article.In addition, we find that now high-melting-point liquid can add in the agglomerated particle and keeps acceptable unrestricted flow character simultaneously.Therefore, the present invention relates to a kind of improvement method that forms agglomerated particle, described agglomerated particle contains the acid activity material and is selected from the core substance of acid-sensitive sensitive polymeric, high-melting-point liquid and their mixture.When having acid-sensitive sensitive polymeric, the method for this improvement is by the inner degraded that reduces acid-sensitive sensitive polymeric of the alkalescence that it is concentrated into agglomerated particle, the polymer property that is maintained, unrestricted flow character and performance profile and do not increase formulation cost.When high-melting-point liquid was used for herein, the method for improvement was by being concentrated to it inner unrestricted flow character that keeps agglomerated particle of particulate.
The present invention relates to form the method for agglomerated particle, it contains provides at least a alkaline matter, be selected from acid-sensitive sensitive polymeric, high-melting-point liquid and the core substance of their mixture and the step of at least a acid activity material.Alkaline matter and core substance add in the mixing tank, and agglomeration therein contains inside and outside agglomerated particle with formation, add the acid activity material subsequently in mixing tank.In core substance adding alkaline matter that will be all basically before the acid activity material that surpasses about 50% adds mixing tank, core substance is concentrated to the inside of agglomerated particle.
By reading disclosure and appending claims, those skilled in the art will know these and other feature of the present invention, aspect and advantage.
Describe in detail
According to the present invention, we find that agglomerated particle can use acid activity material and acid-sensitive sensitive polymeric simultaneously, the degraded of also having avoided the acid in time of acid-sensitive sensitive polymeric to cause.The method of improving has reduced degraded, thereby has improved the validity of a certain amount of acid-sensitive sensitive polymeric in the cleaning composition.Owing to do not need to add the degraded of extra acid-sensitive sensitive polymeric with the compensation expection, the method for improvement can also keep polymer properties profile and benefit and reduce formulation cost simultaneously.When high-melting-point liquid was used for this paper, present method had also obtained having acceptable unrestricted flow character, for example agglomerated particle of the caking of Jiang Diing.
All percentage ratios, ratio and ratio are by agglomerated particle weight, except as otherwise noted.All temperature be degree centigrade (℃), except as otherwise noted.The document of all references is listed this paper in as a reference.
The term " alkyl " that is used for this paper is meant straight or branched, saturated or undersaturated alkyl; except as otherwise noted; alkyl preferably saturated or two keys undersaturated, preferably have one or two pair key, being included in the term " alkyl " is the moieties of acyl group.
The revolution that is used for term " RPM " the expression per minute of this paper.
According to the present invention, we recognize and some material that for example high-melting-point liquid, the acid-sensitive sensitive polymeric specific question relevant with their mixture can be avoided by the core that they is added agglomerated particle, and this material is called " core substance " hereinafter.According to the present invention, we recognize acid, the acid activity material that in common agglomeration process, exists some polymkeric substance of can degrading especially, thus reduce their effects in cleaning composition.Therefore, this polymkeric substance is referred to herein as " acid-sensitive sensitive polymeric ".Although do not plan to be limited to theory, we believe that the acid activity material can react to cause its degraded with acid-sensitive sensitive polymeric, for example reacts to reduce the character of acid-sensitive sensitive polymeric in cleaning composition, for example soil dispersion character with active group.In addition, the acid activity material can with the reaction of acid-sensitive sensitive polymeric skeleton, with its hydrolysis with resolve into less fragment, they are obviously not too effective in cleaning composition.
Method of the present invention has also reduced the unwanted polymerization of acid-sensitive sensitive polymeric.Although do not plan to be limited to theory, but we believe that some acid-sensitive sensitive polymeric can not form homopolymer or multipolymer with catering to the need when being exposed to acid, and polymkeric substance effect and the performance in the final composition can be destroyed or be reduced in to this undesirable polymerization process.
Though at common detergent composition neutral and alkali material is excessive, we were surprised to find after agglomeration process is finished several hours, and (for example about 20-50%) may not exclusively neutralize at quite most acid activity material.Therefore, we find can need several days with the neutralization fully that becomes at the acid activity material that the agglomerated particle outside exists, or in some cases, never neutralization fully.Therefore, we recognize when the acid activity material that exists is neutralized at once that it is acid that the acid activity material that exists still keeps for a long time after agglomeration process is finished in the particulate outside in the inside of agglomerated particle.In this process, if acid-sensitive sensitive polymeric is dispersed in the whole particle, the acid activity material that exists in the outside of agglomerated particle these acid-sensitive sensitive polymerics of can degrading.
In agglomeration process, at first the component of Jia Ruing is concentrated to particulate inside usually, subsequently the component of Jia Ruing appear at that particulate is concentric, in the skin successively.Method of the present invention is before the acid activity material that surpasses 50% adds mixing tank, and all core substances add in the alkaline matter basically.After core substance adds in the mixing tank, add remaining acid activity material, after agglomeration process proceeds to all components adding.
When core substance contained acid-sensitive sensitive polymeric, the method for this improvement was by being concentrated to acid-sensitive sensitive polymeric the very alkaline inside of agglomerated particle, and promptly the inside of " onion " has reduced degraded.Although do not plan to be limited to theory, we believe that the inside of agglomerated particle provides alkaline environment, and it prevents acid-sensitive sensitive polymeric because the degraded that acid causes.In addition, we believe since acid-sensitive sensitive polymeric everywhere by the excesses of basic substances encircle, DeR drops to minimum; Therefore, any acid activity material that exists with acid-sensitive sensitive polymeric, it have an opportunity with acid-sensitive sensitive polymeric reaction before, with excessive alkali substance reaction, be neutralized basically immediately.
In addition, method of the present invention protects acid-sensitive sensitive polymeric to avoid remaining in the acid activity material of agglomerated particle outside.In the agglomerated particle of the inventive method preparation, the inside of containing acid-sensitive sensitive polymeric is surrounded by many layer alkaline matter layers, and the layer of these encirclements also protects acid-sensitive sensitive polymeric to avoid the degraded of acid activity material.Therefore, because acid-sensitive sensitive polymeric is concentrated in particulate inside, the middle layer that any acid activity material that remains in the particle outside must be by many alkaline matters is reaching, and then the degradation acid sensitive polymer.Because outside acid activity material was neutralized before arriving acid-sensitive sensitive polymeric equally, the embracing layer of alkaline matter provides the extra play of protection.
The method of improving also provides additional effect.For example, because acid-sensitive sensitive polymeric is normally expensive, the present invention adds less acid-sensitive sensitive polymeric by needs and has reduced formulation cost so that identical beneficial effect to be provided.On the contrary, because effective effect of this acid-sensitive sensitive polymeric depends on their concentration in cleaning composition usually, method of the present invention has been improved the general effect of certain density acid-sensitive sensitive polymeric.
When core substance contained high-melting-point liquid, method of the present invention also provided the surprised advantage of producing the free flowing powder of the caking susceptibility with reduction.This feature is very to need in the particle cleaning composition, because it has improved the attractive in appearance and solubility curve of composition.Although do not plan to be limited to any theory, we believe that it is distributed in the whole particle when high-melting-point liquid adds in the typical agglomeration process, yet in this particle, high-melting-point liquid can for example be diffused into the particulate surface in time in storage process.When this thing happens, the particle thickness that becomes itself trended towards and other particle caking, and this further produces caking, has reduced the unrestricted flow character of composition, thereby caused the performance and the solvability that reduce.Yet we are surprised to find when this high-melting-point liquid is concentrated in the inside of agglomerated particle by method of the present invention now, keep acceptable unrestricted flow character.Although do not plan to be limited to theory, but we believe when it is concentrated in the inside of agglomerated particle rather than is dispersed in the whole particle, the less surface that is diffused into of high-melting-point liquid, and this generation has the particle of acceptable unrestricted flow character, it is not too sticking, not too trends towards caking and reunion.In addition, when high-melting-point liquid when still being acid-sensitive sensitive polymeric, this method has reduced the degraded of sour initiation by the outside that reduces acid-sensitive sensitive polymeric and be diffused into agglomerated particle.Agglomerated particle itself by method preparation of the present invention can be used as cleaning composition, or can mix with other component to form cleaning composition.
In the method for the invention, provide at least a alkaline matter, its neutralizing acid active substance.Alkaline matter can be the material of any cleaning composition that is used for, especially laundry composition.Alkaline matter is selected from basic metal and alkaline earth metal carbonate, phosphoric acid salt, silicate, layered silicate, oxyhydroxide and their mixture usually.

Method of the present invention comprises adding core substance and alkaline matter and agglomerant therein step in mixing tank.The type that is used for the mixing tank of this paper comprises the soup compound mixing tank of the batch type of commercially available acquisition, for example V-mixing tank, ploughshear mixer, Fukae mixing tank etc.Method as herein described can be carried out in single mixing tank or a plurality of as required mixing tank.Specifically, moderate-speed mixers and super mixer are that this paper is preferred.
Moderate-speed mixers of the present invention is to have rotatable central shaft and some usually radially mixing tanks of the arms of extension.Be used for when of the present invention, " moderate-speed mixers " is such mixing tank, and wherein central shaft preferably is lower than about 500RPM to be lower than about 750RPM, more preferably less than the speed rotation of about 250RPM.The preferred moderate-speed mixers that is applicable to this paper is Loedige KM " colter ", and the KM mixing tank has rotary middle spindle and some arms that is extended by central shaft, has the triangle interconnecting piece that is called " plough " at the end of arm.But in mixer chamber the less blade of some high speed rotating that extend by mixer wall.Certainly, other moderate-speed mixers also can be used among the present invention, is obtained by the various sources that comprise Schugi.Equally usefully double-screw mixer is commercial as Eirich, O ' Brien and the sale of Drais mixture.The mean residence time of agglomerated particle was generally about 0.5 minute-Yue 15 minutes in moderate-speed mixers, and preferred about 2 minutes-Yue 10 minutes, more preferably from about 3 minutes-Yue 8 minutes.
The super mixer that is used for this paper can be the obtainable super mixer of any commerce/fine and close device, for example Schugi mixing tank/cyclone agglomerator or Loedige CB mixing tank.Other mixing device can be used for the present invention, can comprise conventional double-screw mixer.These and other super mixer can be obtained by many sources commercial.Be used for when of the present invention, " super mixer/fine and close device " is to have central shaft speed at least about 750RPM, more preferably at least about 1000RPM with most preferably at least about the device of 1200RPM.Being used for preferred super mixer of the present invention/fine and close device is K-G/Schugi mixing tank-cyclone agglomerator, and Schugi mixing tank-cyclone agglomerator has the centre rotational axis that has a plurality of revolving vanes that extended by central shaft and flexible outer rubber wall to prevent the particle plugging on the wall outside.The mean residence time of agglomerated particle was generally about 0.1 second-Yue 50 seconds in super mixer, and preferred about 0.1 second-Yue 30 seconds, more preferably from about 0.1 second-Yue 15 seconds.
The acid activity material that is used for this paper is usually in about 65% by the about 10%-of agglomerated particle weight, and preferably about 12%-is about 45%, and more preferably from about the content of 15%-about 35% exists.
Core substance and especially a kind of acid-sensitive sensitive polymeric very lower concentration provide, and therefore can be difficult to be dispersed in the whole mixing tank.Therefore, in preferred embodiments, provide carrier before agglomeration step, to disperse or dissolve core substance to form premixture.Since core substance normally solid or thick liquid with because core substance adds with relative low concentration, carrier help core substance is dispersed in whole particle; Be each particle within it portion contain core substance.Carrier is liquid normally, can only maybe can play dual purpose as carrier.Wherein form premixture if acid-sensitive sensitive polymeric is dispersed in, carrier is preferably non-acid, for example water.What be equally applicable to this paper is nonaqueous carrier or basic supports.
In some cases, even can cause degraded, before agglomeration process, need or mixing acid sensitive polymer and acid activity material very easily.When for example mixing tank only contained a single liquid feeding pipeline, this can take place.Therefore, in embodiments of the invention, we are surprised to find the acid activity material and itself can be used as carrier.The degraded of finding acid-sensitive sensitive polymeric is with concentration dependent and relevant with the time.Therefore, the concentration of existing acid activity material and/or acid-sensitive sensitive polymeric is big more, and DeR is fast more.Equally, the time that acid activity material and acid-sensitive sensitive polymeric exist together is long more, and it is big more to degrade.
Therefore, acid activity material itself can be used as the carrier of core substance in the method for the invention.If core substance is acid-sensitive sensitive polymeric, then very need to reduce the reaction kinetics and the degraded of acid-sensitive sensitive polymeric.Therefore, be no more than about 50% acid activity material, preferably be no more than about 25% acid activity material, the acid activity material more preferably no more than about 10% should add in the premixture.For reducing reaction times and reaction kinetics, premixture must add in the mixing tank as early as possible.Therefore, if acid activity material and acid-sensitive sensitive polymeric mix the formation premixture, premixture should preferably add in about 15 minutes in the mixing tank of agglomeration step at about 60 minutes that form premixture.In the more preferred of the inventive method, acid-sensitive sensitive polymeric is dispersed in the acid activity material to form premixture, in fact it immediately, the time of promptly about 0.1-10 second is with alkaline matter agglomeration in mixing tank.This can finish at second mixing tank of preceding outlet line or the syringe of static mixer and input agglomeration mixing tank by for example being provided with two liquid feeding pipelines and one.Therefore acid-sensitive sensitive polymeric can be dispersed in the acid activity material in this second mixing tank, and is injected into immediately in the agglomeration mixing tank.This method is particularly useful for continuous agglomeration method.
If exist, thereby must provide enough carriers to make acid-sensitive sensitive polymeric disperse easily, preferred dissolution is therein to form premixture.The weight ratio of carrier and core substance is generally at least about 1: 1 in premixture, and preferred about 1: about 8: 1 of 1-.
In preferred embodiments, method of the present invention is used for continuous agglomeration method.In typical method, at least one syringe contains core substance, and preferred acid sensitive polymer and at least one other syringe contain the acid activity material.For example, if use single agglomeration mixing tank with at least two liquid feeding pipelines, then first feeding line can contain acid-sensitive sensitive polymeric (separately or in premixture), and when alkaline matter adds fashionablely continuously, acid-sensitive sensitive polymeric is injected in the cyclone agglomerator continuously.When particle agglomeration and when becoming big, they move through mixing tank at " dirty ", and they run into second feeding line at this.Second feeding line is injected remaining acid activity material continuously, so agglomerated particle will contain the acid-sensitive sensitive polymeric that is concentrated in its inside.
In another preferred embodiment of continuation method, two isolating agglomeration mixing tanks are connected in series.Acid-sensitive sensitive polymeric adds in the alkaline matter in the first agglomeration mixing tank.Formed particle is pumped into the second agglomeration mixing tank subsequently, adds the acid activity material therein, and agglomeration process is a successive.
