Abstract
The present invention is to mix sepiolite powder, alkaline activating agent and surface active agent ot proceed activation reaction so as to obtain the greyish white sepiolite powder product. This product is a pure netural adjuvant for detergent, which is non-toxic and contains no phosphorus. After adding detergent powder, its detersive power, calcium magnesium chelating ability, solubility, emulsifying and absorplion ability for dirt are equal to or better than sodium tripolyphosphate, so that it is an ideal substitute for sodium triphosphate.
Description
The present invention relates to a kind of activation sepiolite composition and method of making the same, it belongs to the daily-use chemical industry technical field.
Washing powder is articles for washing commonly used in the daily life, and not only detersive power is stronger, and saves time conveniently, is subjected to human consumer's welcome deeply.The output in China's washing powder every year reaches 2,000,000 tons.Along with the raising of living standards of the people, the quickening of social rhythm, the consumption of washing powder, output also can increase, yet 2,000,000 tons of these digital back, the fact of the secret worry made us are arranged but.We know, washing powder is synthetic by multiple industrial chemicals, wherein tripoly phosphate sodium STPP, water glass, tensio-active agent, fluorescent bleaches, etc. all be hazardous and noxious substances.Tripoly phosphate sodium STPP can cause severe contamination to make water generates " eutrophication " to water resources.Make the phosphorus content in river, river, lake, sea increase (eutrophication), planktonic organisms such as algae breed in a large number, and the oxygen level of water descends, and water quality deterioration muddiness, such water quality make aquatic living things such as fishes and shrimps be difficult to existence, and people and animals' unable to drink is used.Two kinds of tensio-active agents that washing powder uses all are drugs, and heavy dose enters the people and knows from experience deadlyly, even minute quantity enters human body, long-term accumulation also can be brought out diseases such as liver cancer.It is reported that the severe exacerbation of water quality in recent years owing to the phosphorus content severe overweight, has been caused in the Chaohu in one of China five big freshwater lakes.
The pollution that the washing powder toxic action is caused causes the attention of countries in the world already, and many developed countries are progressively eliminating phosphorous washing powder.The cry that China eliminates phosphorous washing powder is more and more higher, and many knowledgeable people are just stepping up to develop the pure natural non-toxic phosphorus-free wash powder.Be related to the project of vital and lasting importance of environment protection and descendants's health for this, caused people's attention and deep thinking.And the research and development of tripoly phosphate sodium STPP substitute are the keys of studying and producing nontoxic non-phosphide detergent.
Purpose of the present invention is exactly in order to research and develop the ideal substitute of the nontoxic without phosphorus tripoly phosphate sodium STPP of a kind of pure natural, make it in chelating calcium magnesium ability, surpass tripoly phosphate sodium STPP on the key indexs such as detersive power comprehensively, and proposed a kind of design that activates the sepiolite composition and method of making the same.
Main contents of the present invention: selected sepiolite group mineral powder, alkaline activation agent, tensio-active agent are mixed, carry out priming reaction, make activation sepiolite composition, it is formed proportioning and is respectively: sepiolite group mineral powder 40%～80% alkaline activation agent 5%～30% tensio-active agent 5%～30%
Carry out priming reaction, need add activator.The used activator of the present invention can be alkaline matters such as yellow soda ash, sodium hydroxide.
Tensio-active agent can be selected tensio-active agents such as soap (comprising soda soap and potash soap) or alkyl polyglycoside for use.
Water content＜5% of the raw material sepiolite group breeze that activation sepiolite composition is required, the sepiolite group breeze can be selected sepiolite, attapulgite, sloping Lou ore ores such as (mountain soft rocks) for use.We know that sepiolite has three big characteristics: (1) high adsorption capacity.The adsorptive power of sepiolite is all stronger than other clays, can adsorb 2～2.5 times water of own wt, and can adsorb nonpolar organic constituent, can be used as good sorbent material etc.(2) have great inner surface, numerous duct, inside, and have the good mechanical resistance for ion exchange reaction and catalyzed reaction provide very advantageous conditions, still can keep the shape and the mechanical stability in duct after the activated reaction.(3) itself have certain emulsification, thickening and suspending power.Above-mentioned three characteristics provide favourable condition for making the activation sepiolite.
This activation sepiolite mainly as the main auxiliary agent of nontoxic non-phosphide detergent, substitutes tripoly phosphate sodium STPP.Activation sepiolite itself also is the nontoxic free phosphate detergent of a kind of good pure natural, and its washing effect reaches the washing effect of common washing powder, also can be used as industrial clean-out system.
The activation sepiolite is used in the washing powder manufacturing, have good washing effect and environmental benefit, does yet how it produce? mainly be sepiolite group mineral powder, alkaline activation agent, tensio-active agent to be mixed carry out priming reaction, make activation sepiolite product, concrete preparation method may further comprise the steps:
(1) selected sepiolite group mineral powder (general preferred sepiolite breeze) is dried under 150-200 ℃ of temperature, makes moisture content＜5%,
(2) with the oven dry three kinds of raw materials of sepiolite group mineral powder, alkaline activation agent, tensio-active agent be mixed even, then
(3) mixture being sent into the mixing of carrying out in the ultrafine crusher repeatedly pulverizes, carry out priming reaction, finally make a kind of newborn pale powder shape activation sepiolite product, it is formed proportioning and is respectively: sepiolite group mineral powder 40%～80% alkaline activation agent 5%～30% tensio-active agent 5%～30%
Above-mentioned activation sepiolite product also can add suitable softening water, uses drying process with atomizing then and is sprayed into powder-like product, can be directly as the nontoxic free phosphate detergent product of pure natural.Can be made into various free phosphate detergents again by adding other activeconstituents and auxiliary material.
This technology has the advantage that production technique is simple, easy to operate, production cost is low.Its outstanding characteristics of activation sepiolite that go out with this explained hereafter are that active area is big, the reactive behavior height.After the activation sepiolite adds in the washing powder as auxiliary agent, can very fast high dispersing in bath water, formation has the active micelle on very big inner surface, its surface and a large amount of sodium ions of brilliant road internal adsorption and the calcium ions and magnesium ions generation ion-exchange absorption reaction in the bath water, simultaneously by forming fatty acid calcium and fatty acid magnesium on its surface, consume calcium ions and magnesium ions, thereby improved the efficient of softening water effectively.Simultaneously by priming reaction sepiolite grain surface and brilliant road internal adsorption abundant fatty acid sodium, add the little fat acid calcium and the fatty acid magnesium that form in the softening water process, it is active strong to form exhibiting high surface, active micelle with strong solublization (for tensio-active agent) and solubilizing power (for dirt), in washing process by surfactivity, absorption, emulsification particularly number of mechanisms such as solubilization effectively remove dirt, and other surface active ingredient of washing composition is played the effect of washing that helps of synergy.
Activation sepiolite composition is compared with tripoly phosphate sodium STPP and has been strengthened performance aspect following:
(1) detersive power has reached common detergency power of laundry powder level than the obvious raising of tripoly phosphate sodium STPP.
(2) absorption, solubilising and the suspending power to dirt is stronger, and the antiredeposition ability reaches or is better than tripoly phosphate sodium STPP and common washing powder.
(3) whole raw materials of activation sepiolite are the nontoxic product of pure natural, and used alkaline activation agent and tensio-active agent biological degradation rate height have good environmental benefit.
(4) soap itself is as a kind of traditional pure natural non-toxic detergent, itself has very strong washability and biological degradation rate preferably, but because resistance to hard water is poor, easily generates calcium soap and magnesium soap and loses washability.But after sepiolite carries out priming reaction, anticalcium magnesium ability strengthens greatly, and what kind of forms cotton-shaped undissolved calcium magnesium soap precipitation, good dispersion property no longer to resemble common soap behind the adding hard water, washability strengthens on the contrary to some extent, and this has just picked up an approach for the application of soap.
(5) activation sepiolite composition not only has stronger surfactivity, detersive power and anti-redeposition performance as a kind of washing auxiliary detergent or washing composition, and to the washes not damaged, the clothing after the washing is soft bright; Also has stronger germicidal action and alkalescence (sterilizing ability of soap itself and alkalescence) simultaneously.Therefore, compare with tripoly phosphate sodium STPP, the activation sepiolite is a kind of multi-functional washing auxiliary detergent or washing composition, can have multiple functions such as anti redeposition agent, fungistat, weighting agent, ealkaline buffer, softening agent and thickening material simultaneously.
