Description
Technical field
The invention belongs to the daily article for washing technical field, be specifically related to a kind of modified alta-mud and a kind of washing powder.
Background technology
At present, fabric softener product major function raw material generally all adopts cats product.The softener prescription is generally simple cats product formulation composition, belongs to the submissive product of rinsing type.Its service requirements can not be used simultaneously with the washing composition of anionic surfactant system, need add separately in the fabric rinsing stage.
Have stronger electrical function between cats product and the anion surfactant, on the one hand, the anion/cation tensio-active agent mixed system of certain blending ratio has high surface, and is as shown in table 1 below.
Table 1: the micelle-forming concentration cmc of mixed surfactant and lowest surface tension γ
Cmc(25 ℃)
| Surfactant system | cmc/mol.dm -3 | γ cmc/mN.m -1 |
| 1∶1C 8N(CH 3) 3Br-C 8SO 4Na | 7.5*10 -3 | 23 |
| C 8N(CH 3)3Br | 0.26 | 41 |
| C 8SO 4Na | 0.13 | 42.5 |
| 1∶1C 10N(CH 3) 3Br-C 10SO 4Na | 4.5*10 -4 | 22 |
| C 10N(CH 3)3Br | 6.0*10 -2 | 40 |
| C 10SO 4Na | 3.2*10 -2 | 38 |
| 1∶1C 8N(C 2H 5) 3Br-C 8SO 4Na | 8.2*10 -3 | 27 |
| 1∶1C 10N(C 2H 5)3Br-C 10SO 4Na | 20.*10 -3 | 27 |
On the other hand, the mixed system of anion/cation tensio-active agent often is separated more than cmc concentration, even occur precipitating, make the tensio-active agent inactivation, give the composite difficulty of bringing of anion/cation tensio-active agent for this reason, be difficult to develop and have compliance function, wash and protect two-in-one washing powder product.
The technician is through the years of researches accumulation, grasped certain anion/cation surfactant compound technology, composite as: mol ratio such as non-, as to contain polyoxyethylene chain or macromole type cats product application, add amphoterics, add nonionogenic tenside, seek suitable the moon/non-/ positive ternary built surfactant system, or the like.And fabric softening functional type cleaning product major technique realization approach has at present:
1, anion surfactant.Tallow alcohol vitriol for example---be mainly used to wash wool and cotton yarn.Contain a certain amount of free alcohol in the tallow alcohol vitriol, the free tallow alcohol is adsorbed on the fabric, and is soft.But effect is not as following 2 and 3.
2, cats product.The washing composition of band compliance function generally adopts cats product, nonionogenic tenside compound system, and its product is based on liquid product.Though this series products can reach submissive effect, clean effect is undesirable.
3, amino-modified silicone.Similar with cats product, amino in alkaline aqueous solution positively charged, can not with the composite use of anion surfactant, and price comparison height.
In view of the major technique characteristics of above-mentioned fabrics compliance function type cleaning product, the compliance function type cleaning product of anion/cation surfactant compound system also seldom in the market.How to overcome the difficult point of anion/cation surfactant compound in the washing powder---should make cats product play the compliant fabric effect, can not allow the anion/cation tensio-active agent strong interaction take place and inactivation again, influence the product detersive power, be still those skilled in the art's emphasis research topic.
Summary of the invention
First purpose of the present invention is to provide a kind of modified alta-mud, and it is equipped with cats product, can as after join raw material and be applied in the washing powder product of anion/cation surfactant compound system.
Another object of the present invention is to provide a kind of and has compliance function, washes and protect two-in-one washing powder.
For reaching first purpose, the present invention adopts following technical scheme: a kind of modified alta-mud, it is characterized in that, and form by the cats product of wilkinite and macromole sterie configuration.
With the carrier of wilkinite, mainly be to have utilized bentonitic special property among the present invention as cats product: 1, absorption cats product, avoid it directly to contact with the washing powder powder; 2, in the aqueous solution, slowly release cats product, make the exposure concentration of itself and anion surfactant be unlikely to too high; 3, utilize the cation exch ange adsorption performance of wilkinite in the aqueous solution, make cats product in the wilkinite have the balance of a desorption and absorption, make the cationic surfactant concentration in the solution can be relatively stable; 4, after the wilkinite water-swelling, its laminate structure edge can be in conjunction with OH
-, it is slow to make that it discharges cats product speed when high pH value, and release cats product speed is fast during low pH value.Because washing soln is in washing process, the pH value is to change toward low from high, that is to say that cats product is accelerated at the last stages aqueous solution release rate of washing, makes the submissive effect of product more outstanding; 5, wilkinite has certain submissive effect to fabric itself, but after the cats product modification water-soluble and dispersed can variation, itself has reduced the submissive effect of fabric, wilkinite mainly plays carrier function among the present invention.
The cats product that wilkinite carries adopts the macromole sterie configuration, utilizes bigger sterically hindered of macromole cats product, weakens the interaction between the anion/cation tensio-active agent, avoids the inactivation of tensio-active agent as far as possible.
Further, the preferred smectite content that adopts of the present invention is 65～95%, pH is 7～9, expansion doubly is the wilkinite of 30～50ml.
Further, the present invention preferably adopt activating velocity very fast, to the less sodium bentonite of detersive power influence.
Further, the cats product of above-mentioned macromole sterie configuration is meant and is connected with two or more long carbochain groups on the N atom, and has the quaternary cationics of functional group on these long carbochains.The preferred molecular structure of described quaternary cationics is:
As preferably, the above-mentioned wilkinite and the weight ratio of cats product are 10: 1～1: 1.More preferably 7: 1～3: 1.
For reaching second purpose, the present invention adopts following technical scheme: a kind of washing powder, adopt the back allotment of labor preparation of planting, contain aforesaid modified alta-mud, weight percent content at washing powder is 2～20%, and wherein the cats product in the modified alta-mud is 1.0～5.0% at the weight percent content of washing powder; Also contain anion surfactant and nonionogenic tenside, the weight percent content at washing powder is 12.0～25.0% and 1.0～5.0% respectively.
As preferably, the ratio of cats product and nonionogenic tenside is 1: 1～2: 1.
Further, consider the content of cats product in the modified alta-mud and take into account washing powder product appearance and use properties that above-mentioned modified alta-mud is 6～15% at the preferred weight percent content of washing powder.
The present invention also contains water glass, is 0～8% at the weight percent content of washing powder.
It is 20～40% 4A zeolite content and 0.5～4.0% polycarboxylate content that the present invention also contains weight percent content at washing powder.
By the present invention, can obtain to have the washing powder product of stable the moon/non-/ cats product compound system, when having strong soil removability, can further give prominence to submissive effect.
Embodiment
One, cation-modified bentonitic preparation.
1, main raw material:
1) wilkinite: smectite content 65～95%, pH 7～9, and doubly 30～50ml expands; Preferred sodium base.Natural montmorillonite can change the sodium base generally based on the calcium base into by ion-exchange.Sodium base and calcium-base bentonite are that to the key distinction that influences of the technology of the present invention effect the calcium-base bentonite activating velocity is slow, and influential to detersive power, and its submissive effect is than sodium bentonite difference.
2) cats product: macromole type---the sterie configuration of macromole described in the present invention cats product refers to: be connected with two or more long carbochain groups on the N atom, and have the quaternary cationics of functional group on these long carbochains.Present embodiment adopts molecular structure as follows:
Wherein R is C
12～C
