Description
Technical field
The present invention relates to detergent compositions Technology field, and in particular to a kind of cloth-detergent of antibacterial lasting and its
Preparation technology.
Background technology
Detergent is widely applied as article of everyday use and industrial goods, however, existing detergent mostly functionally compares
Single detergent, the performance in terms of degreasing is not ideal enough.In laundry detergent products detergent always in the highest flight, but
Detergent can not be completely dissolved in use, and residue is easily caused medicated clothing damage, be difficult rinsing, and aqueous solution is in alkalescence
(pH value is more than 12), will reduce detergent to skin irritation using during by wearing glove, and detergent produces waste liquid and causes
River eutrophication, to environment.
Liquid detergent compensate for the drawbacks described above of detergent just.Firstly, since its liquid existence, it is easier to which addition adds
Plus agent, more functional products with special-effect are realized, such as add leavening agent, softening agent, antibacterial, make to wash rear medicated clothing
It is fluffy, soft, smooth, glossy, and there is degerming and lasting lasting, it is low using integrated cost；Secondly, laundry liquid energy
Enough it is completely dissolved, dissolution velocity is also fast, easily floats washable, skin and medicated clothing will not be injured, dirt-removing power is strong, can deep enough medicated clothing fibre
Dimension is internal to play cleaning function, and decontamination is more thorough；Finally, the pH value of liquid detergent is 5.5-8, and formula does not gently hurt hands, can be complete
Degraded, does not result in environmental pollution.But the liquid detergent clean effect that can buy on the market now is undesirable, it is impossible to enough permanent
Keep the effect of antibacterial and lasting.And the detergent long-time on existing market captures most parts by external liquid detergent brand
Volume, purchase cost is higher, can not reasonably meet requirement of the domestic consumer to liquid detergent.The purpose of the present invention exists
In on the basis of existing liquid detergent compounded formula, being adjusted with inorganic nano antiseptic powder and modified Nano essence and technique
Improve, effect of high-effective cleansing, antibacterial is reached, while realizing effect of liquid detergent slow release fragrance.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of cloth-detergent and its system of antibacterial lasting
Standby technique.
The cloth-detergent of the antibacterial lasting that the present invention is provided, is made up of, component sum the component of following mass percent
For 100%：

The preparation technology is comprised the following steps：
（1）Prepare inorganic nano antiseptic powder：It is 55 by zinc salt and nano titanium oxide mass ratio：10-15 weighs raw material, is dissolved in
In ethanol, pH=1-3 is adjusted with dust technology, make settled solution, settled solution is sufficiently mixed on magnetic stirring apparatuss；To ammonia
Add ammonium nitrate to form ammonia spirit in water, then settled solution is instilled in ammonia spirit, and stir rapidly, rate of titration is less than
2 mL/min, mixing speed is maintained at 50-200 r/min, can a small amount of ammonia holding pH=8-9 of Deca；After titration terminates, stand
1-5 h；Then cleaned with distilled water, then with washes of absolute alcohol, obtain presoma；Presoma is dried in an oven, grinding, so
Load afterwards in crucible, calcine at a temperature of 1100-1300 DEG C, obtain inorganic nano antiseptic powder stand-by；
（2）Prepare modified Nano essence：It is 2 by the mass ratio of nano silicon oxide, nano titanium oxide, essence and emulsifying agent：
1.2-1.5：0.5-2：0.1-0.7 weighs raw material, and nano silicon oxide, nano titanium oxide add emulsifying after mixing homogeneously with essence
Agent, with dilute hydrochloric acid or dilute sodium hydroxide pH to 1-4, the high speed emulsion dispersion 10-30 min under 8000-15000 r/min are adjusted
Thick liquid is formed, that is, obtains modified Nano essence stand-by；
（3）Dissolved hydrogen water sodium oxide is used, after sodium hydrate solid dissolving, then the kneading with agitating heater is poured slowly into
In machine, under slow stirring, DBSA is poured into；Then sequentially add acid blue dye, slow release-excipient I, delay
Release-excipient II, step（1）The inorganic nano antiseptic powder of middle gained and Matrii Sulfas Exsiccatus, keep heating-up temperature in 40-80 DEG C of scope,
Stirring kneading time is 0.5-1.0 h, afterwards natural cooling；
（4）It is eventually adding step（2）The modified Nano essence of middle gained, continues to be stirred until homogeneous, and subsequently stands overnight, and obtains into
Product.
Described acid blue dye is a kind of or many in acid lake blue, edible light blue, Coomassie brilliant blue, Mayan basket
The arbitrary proportion mixture planted.
Described slow release-excipient I is xanthan gum and stearic mixture, and slow release-excipient II is xanthan gum and sulfur
The mixture of sour copper；The xanthans content for constituting slow release-excipient I is 45-55%；Constitute the xanthan gum of slow release-excipient II
Content is 50-60%.
Described inorganic nano antiseptic powder is co-precipitated and is formed by zinc salt and nano titanium oxide Jing, and zinc salt can be bromine
Change zinc, zinc chloride, zinc sulfate, zinc nitrate.
Described is daily chemical essence for essence prepared by modified Nano essence；It is described for preparing modified Nano essence
