Detergent powder bag and preparation method thereof
Technical field
The present invention relates to daily detergent applications.More specifically, the present invention relates to a kind of detergent powder bag and
Its preparation method.
Background technology
Polyvinyl alcohol (PVA) water-soluble film, as a kind of packaging film material, pesticide, detergent,
Application has been arrived in the fields such as food.Compared to other PP, PE, PVC film, the biological degradability of PVA film to get well,
It is dissolved in noresidue after water, and eliminates a lot of trouble when packing for article, packaging can be taken apart directly
Use, conveniently measure.At present, occurred in that PVA film is applied to the product of liquid detergent
The green solidifying pearl of wave laundry, this series products need not contact detergent itself, according to laundry amounts first use when of use
One or two, will not splash the when of use, easily, commercially be favored by a part of consumer.
At present in disclosed PVA water-soluble packed detergent patent, it is all about the water-soluble bag of liquid detergent
Dress dissolving, detection method and the research of packaging molding thereof, water-soluble to PVA without reference to component in detergent powder
The impact of packaging.As CN101517061A discloses a kind of detergent bag, this patent mainly solves detergent
Middle spice hides problem to PVA film abnormal smells from the patient and can fragrance do not mention other through the problem of PVA film
The impact that water soluble film is packed by detergent component.Liquid detergent composition and detergent powder have bigger difference,
The acid-base value of two kinds of products has the biggest difference: general liquid detergent, mainly based on surfactant, contains
A small amount of inorganic or organic salt auxiliary agent, for neutral or low alkalinity;Detergent powder surface-active contents is less than
Liquid detergent, containing the raw materials such as more inorganic salts auxiliary agent such as inorganic alkaline raw material, Sulfates compounding and
Become, be typically high alkalinity.PVA film has fabulous oil resistivity, organic solvent-resistant and carbohydrate etc.,
But highly basic, strong acid, chlorine radical and other can with PVA occur chemical reaction material (as Borax, boric acid,
Some dyestuff etc.), thus PVA film is used as the detergent powder packaging compounding containing plurality of raw materials, need comprehensive
Consider the recipe ingredient impact on PVA film, it is especially desirable to concern as to whether that the dissolubility to film and storage stability have
Impact.
The regular powder commercially available by trial PVA film packaging and concentration powder, through constant temperature and humidity 37 DEG C 75%
Storing January under humidity, the result almost compatibility all there is a problem, PVA film occurs that variable color, dissolubility are deteriorated
Even can not dissolve.For the problems referred to above, the present invention is by the rational proportion of recipe ingredient and production technology
Optimize and revise, get rid of influential component, the production technology of conservative control powder, improve PVA water soluble film and powder
The compatibility of shape detergent, is more suitable for PVA water soluble film packaging than generally conventional detergent formula, can make powdery
Detergent product shelf life of contracting for fixed output quotas is longer.
Summary of the invention
It is an object of the invention to provide a kind of detergent powder bag, it is desirable to provide one is done washing easily and used powder mode
And solve conventional detergent powder formula and be not suitable for the situation of water-solubility PVA packaging film, by optimization of C/C composites structure
With technology controlling and process make content detergent powder and PVA film can good compatibility so that use PVA film bag
The detergent powder of dress is surrounded by well solubility property, good clean effect.
The present invention reaches goal of the invention by following technical method:
A kind of detergent powder bag, is packed by water soluble package material and detergent powder content and forms, and it is special
Levy and be:
Described water soluble package material selection polyvinyl alcohol film or modified polyvinylalcohol thin film;
Described detergent powder content is formed by following components configuration:
Wherein: inorganic base selects sodium silicate, anhydrous partial silicon, metasilicate pentahydrate sodium, sodium carbonate, potassium carbonate and carbonic acid

Organic acid selection citric acid, oxalic acid, linear dodecylbenzene sulfonic acid, tartaric acid and 1-hydroxyl ethylidene-1,1 '-
A kind of or the most several mixing in di 2 ethylhexyl phosphonic acid (i.e. HEDP);
Enzyme selects the one or any several mixing in protease, lipase, cellulase, amylase.
Brightening agent selects 4-4-stilbenesulphonic acid base diphenyl disodium (trade name CBS-X, CF-351) or hexichol
Any in ethylene triazine amidodisulfonic acid sodium (trade name DMS, DMA-X, 2M/GLT, 33# brightening agent etc.)
One or both mixture;
One in acrylate homopolymer, maleic acid-acrylic acid copolymer and Styrene And Chloroalkyl Acrylates that polymer is selected
Or the most several mixing.
Described detergent powder bag, is characterized in that:
The thickness of water soluble package material is in 35 μm~50 μm;
Nonionic surfactant select carbon chain lengths 12~15 and ethylene oxide number 7~9 fatty alcohol polyoxy
Vinyl Ether
Polymer is graininess.
The preparation method of described detergent powder bag, is characterized in that: implement as follows:
Put into inorganic base, surplus Natrii Sulfas, 3%~10% organic acid successively, in mixer after stir about 5min again

Finding out from the above, along with the prolongation of the time of storage, the PVA bag dissolubility equipped with commercial laundry powder is bright
Aobvious being deteriorated, after storing surrounding, 1 detergent PVA bag can not break dissolving, and other 2 break and wash around
Wash the time, so it is shorter to pack commercial laundry powder shelf life with PVA film.And the PVA laundry of embodiment 1~5
Powder bag is little along with the prolongation dissolubility change of the time of storage, thus can have longer shelf life.
