Abstract
The present invention discloses one kind of surfactant for after compounding to washing powder and the washing powder therewith. The surfactant is prepared with flaky MES, and through freeze drying, crushing and sieving, and the washing powder with the surfactant is produced through after compounding the surfactant into washing powder. The present invention applies MES as one new kind of surfactant with high performance/cost ratio and high cost superiority successfully in washing powder, and has wide application foreground.
Description
Technical field
The present invention relates to a kind ofly be applied to the tensio-active agent in allotment of labor's skill behind the washing powder, and contain the washing powder of this tensio-active agent.
Background technology
MES (alpha-sulfo fatty acid methyl ester sodium salt) adopts natural reproducible raw material Oleum Cocois, palm wet goods glyceride stock is through sulfonation, the product that obtains after the neutralization, it is a kind of well behaved tensio-active agent, has excellent lime soap dispersing power, low irritant and favorable biological degradability, compare with the tensio-active agent of present use and on cost performance, to possess suitable advantage, and has an environment protection significance, be used for substituting oil by product alkyl benzene sulphonate (ABS) such as LAS (Sodium dodecylbenzene sulfonate) Application and Development at aspects such as washing composition and personal care articles, the common problem that the solution industry is relied on for a long time oil is significant, has broad prospects in the washing sector application.
Yet MES still is being in space state aspect the washing sector application at present, and its major cause is:
1) owing to each side reasons such as technology, equipment, funds, the MES raw material still can not be produced at home on a large scale, and has only the MES product of chip solid at present.
2) if MES is applied to allotment of labor's skill before the washing powder, because high temperature, the high alkalinity of the washing powder slip of allotment of labor's skill before the washing powder, MES can issue unboiled water and separate in high temperature, high alkalinity condition, influence final product quality, and MES has certain influence to the rheological of washing powder slip, is applied to join before the washing powder have technical difficulty in the production.
3) if MES is applied to allotment of labor's skill behind the washing powder, though avoided high temperature, overbasic influence, but because its outward appearance is a sheet, be not inconsistent with the washing powder powdery appearance, and owing to the viscosity of MES itself and 50～60 ℃ of characteristics that just are in molten state, if only carry out simple crushing process, then can't solve the blockage problem that occurs in the shattering process.
4) even the broken powdery MES that comes out because itself is mobile poor, is difficult to blanking in feed bin, cause blockage phenomenon, can't keep and reach the requirement of joining the stable processing technique blanking behind the washing powder.
Summary of the invention
The objective of the invention is at the problems referred to above, a kind of tensio-active agent is provided, this tensio-active agent contains the MES of powdery form, may be used on behind the washing powder in allotment of labor's skill.
Another object of the present invention is that a kind of washing powder further is provided, and it contains well behaved tensio-active agent MES.
The technical scheme that realizes first purpose of the present invention is as follows: a kind of tensio-active agent is made by the method that comprises the steps:
A, sheet MES is carried out lyophilize handle, the treatment time is no less than 8 hours, and freezing temp is not higher than 20 ℃;
B, the sheet MES that handles through lyophilize is carried out break process, shattering process feeds cryodesiccated air, and air themperature is not higher than 20 ℃;
C, the processing of sieving.
The above-mentioned lyophilize treatment time is preferably 8～24 hours.
The stability that be to keep MES, above-mentioned MES after break process can add solid-state zeolite or soda ash and mix after the processing of sieving again.The add-on of solid-state zeolite or soda ash is 0～50% of a mixture total weight amount.
In the above-mentioned treatment step that sieves, the size of sieve is 10～150 orders.
The technical scheme that realizes second purpose of the present invention is as follows: a kind of washing powder, except that containing conventional washing powder original washing powder, also contain the tensio-active agent that obtains via the present invention's first purpose technical scheme.
In above-mentioned washing powder, the powdery MES in the tensio-active agent accounts for 3～10% of washing powder gross weight.
Washing powder of the present invention is joined raw material after also can containing other conventional washing powder, as anion surfactant, nonionogenic tenside, washing assistant, spices etc.
The present invention successfully is applied to MES behind the washing powder in allotment of labor's skill, solved the problem that MES but can't be applied at China washing powder as a kind of novel surfactant of excellent performance, because MES compares with the tensio-active agent of present use and possess bigger advantage on performance and price, have broad prospects in the washing sector application.
Embodiment
One, preparation contains the tensio-active agent of MES
1) sheet MES is placed the refrigeration chamber 8～24 hours of freeze drying plant, freezing temp is not higher than 20 ℃, enters MES temperature before broken below 20 ℃;
2) the sheet MES after the lyophilize enters blanking bin and arrives the crusher in crushing system, and the air of the required feeding in broken ingress will become dry refrigerated gas and just can enter crusher through being cooled to below 20 ℃;
3) through the powdery MES after the fragmentation with certain granules degree, put into mixing tank, being mixed with other two kinds of solid material zeolites or soda ash, (add-on of zeolite accounts for 0～50% of gross weight, the add-on of soda ash be gross weight 0～50%), start mixing tank, mixing process needs to make it even more than 10 minutes;
4) mixing raw material is through processings of sieving of 10～150 purposes sieves, guarantees to obtain the mixture of even, no conglomeration, no lump.Mixture enters blanking bin, can be used in the ordinary production of washing powder.
Two, join behind the washing powder
Said mixture stablize blanking to the below belt system by feed bin, joins in the roller equipment after metering is delivered to, and joins raw material with the washing powder original washing powder, after other and mixes, and the powder that comes out from cylinder passes through and is packaged to be the washing powder finished product.Powdery MES accounts for 3～10% of washing powder gross weight.
Constant and all the other the composition unanimities of the thing total amount of remaining valid are partly filled a prescription as table 1 by the resulting finished powder of above-mentioned technology.
Table 1. washing powder product formula
| Prescription | LAS massfraction/% | MES massfraction/% |
| 1 | 100 | 0 |
| 2 | 80 | 20 |
| 3 | 60 | 40 |
Washing powder of the present invention and conventional washing powder in the market compare:
(1) formulation composition: the compound system detersive power by evidence MES and LAS is better than the LAS compound system, and the result is as shown in table 2.Because MES has good resistance to hard water, the addition of comparing auxiliary agent with general prescription can significantly reduce, and the result is as shown in table 3.
Table 2. washing powder promoting agent system is to the influence of detersive power
Table 3. water hardness is to the influence of washing powder detersive power
(2) formulation cost: contain MES prescription contain with now without phosphorus prescription compare cost by a relatively large margin 50～150 yuan/t of decline arranged.
(3) prescription quality: MES prescription is suitable with the fragrant non-phosphate performance formula, all shows well at aspects such as soil removability, foams.With following analytical data is example:
The MES prescription is suitable with the fragrant non-phosphate performance formula as can be seen.In addition the warehouse of some months heap presses test-results to show with adding face powder to compare and do not occurring aspect the caking than big-difference, can not have big caking risk.
Claims (1)
1, a kind of preparation method of tensio-active agent is characterized in that: this method is made up of following steps:
