Description
Technical field
The present invention relates to a kind of daily use chemicals solid-state washing, more particularly relate to a kind of Superconcentrated washing sheet and preparation method thereof.
Background technology
It is in the majority that cleaning product the most on the market is mainly liquid detergent, laundry soap and detergent three class, dominates people's
Daily life.But, one, the high medicated clothing to directly contact of detergent alkalescence or skin have certain injury, contain a large amount of simultaneously
Component of inorganic salts, remain on medicated clothing be difficult to rinsed clean；Two, liquid detergent is mainly by water soluble surfactant active and various
Auxiliary agent forms, and washes rear medicated clothing and easily rinses, and its composition 70% is above water, and single bottle of weight reaches more than 3kg, takes, transports the most not side
Just；Three, laundry soap is light, and detergency is good, warm in nature and do not hinder medicated clothing and hands, but easily softens and deliquescence, is difficult to preserve.
Summary of the invention
The technical problem to be solved is to overcome above-mentioned the deficiencies in the prior art, it is provided that a kind of laundry sheet and system thereof
Preparation Method.
The present invention solves above-mentioned technical problem and the technical scheme is that a kind of laundry sheet, including following by mass fraction
Each component of proportioning:
DBSA 20-25%
Sodium hydroxide 2.4-3.0%
Cocamido propyl betaine 5-9%
Sodium lauryl sulphate 15-25%
Fatty alcohol-polyoxyethylene ether 2-5%
Disodiumedetate 0.2-0.4%
Plant aromatherapy extract 0.6-1%
Pure water surplus.
Preferably, described laundry sheet also includes plant aromatherapy extract.
A kind of preparation method as above-mentioned laundry sheet, comprises the steps:
Adding pure water the most in a kettle., stirring adds sodium hydroxide to being completely dissolved；
B. adding DBSA under stirring, stir to clarify, sodium hydroxide is the most anti-with DBSA
Should be neutral to solution pH value, because the amount of free acid contained by material purity and DBSA is different, can be according to instead
The actual pH value recorded after should increase the consumption of DBSA or sodium hydroxide in right amount, thus regulation solution pH value in
Property；
C. add fatty alcohol-polyoxyethylene ether to stir to clarify, add sodium lauryl sulphate and disodiumedetate continues
Stir 5 minutes to clarification；
D. being slowly added to cocamido propyl betaine, stirring to transparent addition plant aromatherapy extract, this plant aromatherapy extracts
Thing, for liking the different types of essence of addition according to market or client, continues stirring 10 minutes；
The most above-mentioned material stirring injects masterplate, then drying and moulding the most afterwards, and finally section pack gets final product laundry sheet.
Compared with prior art, beneficial effects of the present invention: the present invention uses water soluble surfactant active to compound and forms, and goes
Dirty power is good, easily rinses, and every a piece of grammes per square metre, less than ten grams, is taken a piece of every time, uses convenient storage.Neutral formula, does not hinder medicated clothing
Do not hurt hands.Laundry sheet of the present invention is solid shape, and its effective gross activity thing content reaches more than 70%, is concentrated type on the market
The twice of liquid detergent, 3-4 times of detergent, its clean effect of the consumption of identical grammes per square metre is 23 times of detergent.
The preparation method technique of this laundry sheet is simple, the DBSA of step B and the sodium hydroxide in step A
Occurring exothermic reaction to generate a kind of new surfactant salt dodecylbenzene sodium sulfonate, the heat that reaction produces carries significantly
The high dissolution velocity that material adds below, therefore, without adding hot water or heating in preparation process, is greatly saved
Production cost.

Containing inorganic salt, the most siliceous composition, it is instant that laundry sheet enters water, and after washing, easily rinsing, remains without harmful chemical, very environmental protection and energy saving
A kind of laundry sheet.
The laundry sheet of the present invention is the leading brand of clothes washing with blue moon liquid detergent contrast, blue moon liquid detergent.Press
Wash according to standard GB/T/T13173-2008 " dress material detergent detergency and the mensuration of the circulation scourability " standard of ining contrast to
Clothing powder carries out detergency test, and blue moon liquid detergent and three embodiment laundry sheets of the present invention act on various criterion soiled cotton
Decontamination value in contrast to the decontamination value of standard detergent, and its ratio result is as follows:
| Standard soiled cloth kind | Example one contrast standard detergent | Example two contrast standard detergent | Example three contrast standard detergent | Blue moon liquid detergent contrast standard detergent |
| Albumen soiled cotton | 1.1 | 1.3 | 1.5 | 1.3 |
| Edible oil soiled cotton | 1.5 | 1.7 | 1.8 | 1.7 |
| White carbon black soiled cotton | 1.5 | 1.7 | 1.7 | 1.7 |
Laundry sheet 1% aqueous solution of the present invention is as follows with blue moon liquid detergent 1% aqueous ph value contrast table:
| Test specimen | Example one | Example two | Example three | Blue moon liquid detergent |
| PH value | 7.2 | 7.5 | 7.8 | 8.3 |
By above two groups of list datas contrast can: first, along with the content of the pure water component of laundry sheet reduces, soluble surface lives
Property agent component content increase, i.e. enrichment increase, its dirt-removing power strengthens therewith；Second, the dirt-removing power of laundry sheet is compared
Dirt-removing power in standard detergent is remarkably reinforced；3rd, although the blue moon of the dirt-removing power of laundry sheet and high brand is done washing
The dirt-removing power of liquid is neck and neck, but the pH value that the aqueous solution of laundry sheet wants BELAND moon liquid detergent is gentle many.Therefore can obtain,
The laundry sheet of the present invention not only clean effect is good, and formula is gentle, does not hinder medicated clothing and does not hurts hands.
The above, be only presently preferred embodiments of the present invention, and the present invention not makees any pro forma restriction, appoints
What those skilled in the art, in the range of without departing from technical solution of the present invention, implements above according to the technical spirit of the present invention
Any brief introduction amendment, equivalent variations and the modification that example is made, all still falls within the range of technical solution of the present invention.
