Abstract

The invention relates to the field of laundry supplies, in particular to a non-phosphorous low-foaming washing powder method. The non-phosphorous low-foaming washing powder method includes: filling 50-60 parts of sodium bicarbonate and 2-3 parts of hydroxymethyl cellulose into a mixer to uniformly mix, then adding 1-12 parts of sodium dodecyl benzene sulfonate and 6-10 parts of sodium silicate after mixing, adding 6-8 parts of fatty acid after reaction, adding 4-6 parts of 10% sodium perborate after 24 hours to uniformly mix and adding proper essence and fluorescent brightener. Production equipment for non-phosphorous low-foaming washing powder is simple. The non-phosphorous low-foaming washing powder is low in foaming and applicable to washing machines, utilizes natural plant and animal oil as active matters, is compounded with various high-efficient surfactants and alkalescence builders and is capable of efficiently cleaning, pollution-free and harmless for human bodies. The fluorescent brightener has functions of whitening and brightening, and the essence can make detergents aromatic. The non-phosphorous low-foaming washing powder can be used to wash off gentian violet, ball pen oil, stains of oil, blood, milk, juice and the like which are hard to remove, and is veritable in cleaning.

Description

A kind of preparation method of without phosphorus low sudsing detergent powder

Technical field

The present invention relates to do washing articles for use field concretely, relates to a kind of preparation method of without phosphorus low sudsing detergent powder.

Background technology

According to the report of the mechanisms such as United Nations Environment Programme (UNEP) to global water quality monitoring (WQM), at present the whole world approximately has 30%～40% lake and reservoir the phenomenon of eutrophication to occur.In China, all there is eutrophication problem to some extent in a lot of rivers and lakes such as the Changjiang river, Huaihe River, Taihu Lake, Chaohu.According to the investigation that the expert pollutes water of Chaohu Lake, the phosphorus in water contains easily overproof 3.4 times, and the increase of phosphorus content all comes from phosphorous washing powder.Phosphorus 70.8% in Xuanwu Lake water is from sanitary sewage; Taihu Lake blue algae bloom, one of the main reasons are also because entering of washing powder makes phosphorus content sharp increase in water.Washing powder is originally the thing of cleaning, has nowadays but become the arch-criminal who pollutes.

Originally washing powder is the mixture that is become to be grouped into by number of chemical, and rising mainly, use is tensio-active agent: sodium alkyl benzene sulfonate, sodium alkyl sulfate, Fatty Alcohol(C12-C14 and C12-C18) Ethoxylate, cyclohexane and chloropropane etc.These tensio-active agents can directly be used as washing composition and use.But clean effect is not very good, and cost is high.Therefore, also to add some auxiliary agents and auxiliary during preparation washing powder, make the performance of washing powder more perfect, store and use convenient.The general auxiliary agent of washing powder is divided into inorganic salt and the large class of organic salt two, whether contains phosphorus by washing powder, is divided into again Powdered Detergent Containing Phosphate and non-phosphide detergent.Use comparatively generally tripoly phosphate sodium STPP in Powdered Detergent Containing Phosphate, in tripoly phosphate sodium STPP, negatively charged ion has stronger chelating ability, and fine mineral ion or lipid particle are had dispersion, emulsification, peptization does use, has greatly improved the clean effect of washing powder.But tripoly phosphate sodium STPP and water glass have the strong impulse effect to skin.

Phosphorus is the necessary elements of all biological life, its effect can not be replaced by any other nutrient, but phosphorus is also relevant with environmental degradation, and this is mainly that phosphorus-containing wastewater is discharged in river, lake, causes biological eutrophication in water body, so-called eutrophication, refer to that the nutritive substances such as nitrogen in water, phosphorus, carbon are superfluous and cause the waterplant excessive multiplication, water transparency is descended, and O2 content descends, fishes and shrimps are dead, drinking-water source deterioration.After plant nutrient substance in water body accumulated to a certain degree, water body was too fertile, algae reproduction is rapid especially, and aquatic too system is destroyed.The algae foul smelling, also poisonous, there is one deck cutose on the surface, presents shades of colour, can have a strong impact on water quality.Will form red tide and hydration phenomena.

Be to solve the problem of body eutrophication, developed country has just proposed the new ideas of washing composition without phosphatization as far back as the eighties in 20th century, and has formulated corresponding rules, and the phosphorus content of washing composition is limited and forbids.Canada, Sweden, Japan have all formulated strict law at present, make washing composition reach 100% without phosphatization.China is a washing composition big producing country, produces nearly 3,000,000 tons of synthetic detergent per year.These washing composition generally all contain tripoly phosphate sodium STPP, press existing standard and calculate, and have every year 500000 tons of phosphoric acid salt to flow into rivers,lakes and seas.

The environment specialist thinks, pollution problem is placed hope on to administer afterwards and do not met China's national situation to phosphorus.Sewage is carried out dephosphorization treatment very difficult technically, only have in the world a few countries to set up three grades of a small amount of sewage works, can be substantially except the phosphorus in anhydrating, but cost is huge.China's one-level Sewage treatment systems at present all also is far from popularizing, and it is unpractical that luxurious what is said or talked about alleviates the phosphorus pollution by the sewage dephosphorization treatment.The fundamental way that solves body eutrophication is to reduce the discharging of phosphorus.

Medical research shows, the life-time service height is phosphorous, contain aluminium washing powder, and the phosphorus in the middle of washing powder can directly affect human body to the absorption of calcium, causes the human body calcium deficiency or brings out infantile osteomalacia; Wash clothes with high Powdered Detergent Containing Phosphate, skin often has a kind of sensation of burning, because high phosphorus washing powder has changed the acid or alkali environment in water, makes its richer alkalescence that becomes exactly.If the residual phosphorus of laundry can not be washed down, accumulate over a long period, the residual phosphorus in the middle of clothes will have stimulus effects to skin, especially the tender and lovely skin of baby; In addition, the strong Powdered Detergent Containing Phosphate of alkalescence also easily damages fabric, especially textile, pure hand class, and these reach the washing powder of decontamination purpose life-time service with strong basicity, and clothing also can be burnt.

Summary of the invention

For above-mentioned technical problem, the object of the present invention is to provide a kind of preparation method of without phosphorus low sudsing detergent powder, take the natural animal-plant grease as actives, and composite multiple efficient surfactant and weakly alkaline washing assistant, can keep high-effective cleansing pollution-free, and to human body without harm.

Technical scheme to be solved by this invention is as follows:
