Description

The nanometer P-free sterilization washing powder

Technical field

The invention belongs to the articles for washing technical field, particularly the nanometer P-free sterilization washing powder.

Background technology

As everyone knows, at present widely used have phosphorus washing powder because of containing phosphoric acid salt, contaminate environment, the broken ring eubiosis belongs to the daily washing product that restriction is used or eliminated, because a large amount of phosphorous washess enter rivers,lakes and seas, destroy water quality, produce grave danger for human environmental quality.Because high phosphorus washing powder to the direct stimulation of skin, makes many housewifves produce the sensation of burning pain when laundry, after putting on, back air dried clothes make people's sufferings more than simultaneously and wash.

Summary of the invention

The objective of the invention is to design a kind of nanometer P-free sterilization washing powder, have strong detergency, easily rinsing,, the advantage of not damaging fabric, environmentally safe non-stimulated skin for overcoming the weak point of prior art.

A kind of nanometer P-free sterilization washing powder of the present invention design is characterized in that, mainly formulated by non-ionic surface active and high-effective cationic tensio-active agent and nano-disinfection material, its concrete composition and weight percent are as follows:

Sodium dodecylbenzene sulfonate 6.0-7.5%;

Yellow soda ash 9.5-10%;

Water glass (doing) 2.8-3%;

Na ₂SO ₄ 45-46％；

CMC 0.8-1％；

Nano-disinfection agent 0.1-0.2%;

4A-zeolite 14.5-15%;

C14-18AOS (powdery) 6.0-7.5%;

Fatty Alcohol(C12-C14 and C12-C18) 1-1.5%;

STPP 9.5-10％。

Main raw material and performance specification thereof that the present invention adopts are as follows:

1, Sodium dodecylbenzene sulfonate is called for short A.B.S (Alkylbenzosulfonate) chemical formula C ₁₂H ₂₅C ₆H ₄SO ₃Na, molecular weight 548.98.Have good foaming emulsification, lubricated soil removability.

2, (Sodium Carbonate), is commonly called as soda, Cao Da ash, sode ash, alkali face, washes powder soda ash (formal name used at school) abbreviation yellow soda ash.Molecular formula Na ₂CO ₃. molecular weight 106.00.Soda ash is the noncrystalline thing of white, and natural originates in territory, lake and the hot spring.Have certain detersive power, with fatty dirt saponification and with soil release, and absorption property is arranged preferably and promotes the foam nucleus formation, shared with bubble flower alkali, can reduce infringement to tissue substance intensity.

3, lightweight water glass (formal name used at school) is called for short metasilicate pentahydrate sodium, water glass, practises claiming bubble flower alkali.Molecular formula is Na ₂SiO ₃Molecular weight equals 122.054, water glass be colourless or the Steel Gray thick liquid water-soluble, be alkalescence, do not have to rub voltinism with the hands, do not burn, the first dehydration of being heated, post-foaming is met acid and is decomposed and fold the silica gel precipitation.In washing powder, make washing assistant, increase washing frictional force and soil removability and play mutual coordinative role, stable to suspension, peptization, the negative foam of washing powder, good action is arranged, and be beneficial to the batching operation, be beneficial to particle and form; Weighting material is built in the pass that is puffing washing powder.

4, no bright powder formal name used at school sodium sulfate (.Sodium Sulfatt), being commonly called as saltcake (Saltcake) commodity shape has two kinds in powdery and crystal, and white powdered is an anhydrous sodium sulphate, molecular formula Na ₂SO ₄, component 142 should claim state not have bright powder, molecular formula: Na ₂SO ₄Content 〉=92～98%.The sodium sulfate that contains the hydrate of 10 molecular crystal water, molecular formula Na ₂SO ₄, 10H ₂O.Molecular weight is 322.2, should be called saltcake, content Na ₂SO ₄〉=44%.Do not have bright powder as the auxiliary agent of washing powder, decontamination is arranged, make and be convenient to prevent the effect of luming and reducing cost.

5, Walocel MT 20.000PV claims hydroxy-methyl cellulose to be a kind of derivatived cellulose, to be called for short the CMC polymerization degree n greater than 200 again.Molecular formula [(C ₆H ₇O ₂COH ₂) OCH ₂COONa] n is white powder.

6, nano-disinfection agent is meant that mainly silver, copper, zinc etc. itself have the metal of antibacterial ability or metal ion and are carried on preparation on the inorganic matter carrier.Wherein carrier mainly is synthetic or natural zeolite, titanium dioxide, zirconium phosphate, silica gel etc.Because the toxicity of silver ions is very little, sterilizing ability is strong, and is difficult to accumulation in human body, thus as far back as ancient times people just utilize its security and antibiotic tableware and the antibacterials made.Now commercial sterilant is silver-series antibacterial agent mostly.

7,4A-zeolite claims molecular sieve, claims synthetic zeolite again.The many hydrates of a kind of silicoaluminate, tool cube octahedral crystal structure.The microvoid structure that homogeneous is arranged can arrive cavity inside to the molecular adsorption littler than the aperture, has the effect of screening molecule.But the molecule desorb that is adsorbed, molecular sieve use the back renewable, can use repeatedly.

8, C14-18AOS and STPP are two kinds of phosphorus-free adjuvants.

9, Fatty Alcohol(C12-C14 and C12-C18) is C12-018.

Characteristics of the present invention:

The present invention is a white particle, slight aromatising flavour is arranged, has stronger detersive power, be 2 times of common washing powder, to overstocking the dirt that kind of animal-plant oil is formed, the dirt strong detergency that skin fat, wool lipid are formed especially, do not produce dirt depositional phenomenon again in the washing, washing back clothes whiteness improves, yet can make fabric that shining one new sense is arranged, easily rinsing, save time, water-saving, laborsaving.Non-stimulated to skin, do not damage fabric, environmentally safe, equal three-waste free discharge does not cause environmental pollution in producing and using.

Gross activity of the present invention: 28-36%.
