Abstract
The present invention relates to a disinfection washing powder without phosphorus, which is prepared by compounding sodium dimericsilicate, sodium polyacrylate, anions, a nonionic surface active agent, sodium percarbonate, sodium bicarbonate, 10% to 30% sodium sulfate, etc. The disinfection washing powder has various indices of detersive power, etc. which achieve and surpass a national standard. Discharged waste water does not contain phosphorus absolutely, and used materials are biologically degradable. The disinfection washing powder does not bring any pollution to the environment, has the advantages of bacterium extermination capability greater than 95%, no irritation to a human body, no cumulative toxicity function, no damage to fabrics and vessels, no corrosion, long term safe use, and no harm, and is a disinfection washing article with a wide application range.
Description
The present invention relates to a kind of powdery synthetic detergent and do not have the phosphatization sterilised formula.
Contain the poly-phosphate of 15-50% in the existing prescription that phosphorus washing powder arranged, poly-phosphate causes surface water " eutrophy " change, thus cause great environmental pollution, destroy the eubiosis.Developed country has in the world expressly provided and has limited or banned use of phosphoric acid salt that in the synthesis of detergent product replacing having phosphorus washing powder with non-phosphide detergent is the direction of development.The existing prescription of non-phosphide detergent (number of patent application: the 94104517) mixed thing of employing Starso and sodium polyacrylate, also have and adopt the soft water composition as non-phosphide detergent such as Citrate trianion, nitrogen tritium acetate, zeolite, and use the prescription of simple tween etc. all exist to the dirt ionic suspend, defective such as dispersing property is relatively poor, detersive power is undesirable.
Existing disinfectant detergent powder mostly is chloride or contains the product of doped quaternary ammonium salt, and the former has pungency big, dashes not wash clean the shortcoming that can damage clothing; Latter's sterilisation effect is poor, and soil removability is not strong, causes allergic phenomenon.
The objective of the invention is to improve the shortcoming of above-mentioned prior art, provide a kind of without phosphorus, strong detergency has disinfection, and is non-stimulated to human body, harmless to fabric, and the energy complete biodegradable is to the thorough free of contamination washing powder of environment.
The present invention is achieved in that no phosphatization disinfectant detergent powder of the present invention is to select following composition and weight percent thereof for use:
Two sodium polysilicate 10-30%; Sodium polyacrylate 4-10%; Nonionogenic tenside 10-20%; Anion surfactant 4-10%; SPC-D 8-20%; Sodium bicarbonate 10-30%; Sodium sulfate 10-30%.It is a small amount of that other contains essence.
Two sodium polysilicates can belong to ion with underwater gold to be played replacement(metathesis)reaction and generates water-insoluble.Because the molecular weight of polysilicate is greater than orthosilicate and metasilicate, formed colloidal solution suspends to the dirt ionic, dissemination be better than the back both; Sodium polyacrylate can reduce water hardness, and throwing out is arranged, and makes spot be difficult for deposition; When two sodium polysilicates and sodium polyacrylate mixing use, the dirt ion there are stronger suspension, dispersion, emulsifying effect, and can reduce water hardness, make the suspension of formation be easy to clean; Adopting the composite of nonionogenic tenside and anion surfactant, is the major ingredient of washing, has higher decontamination contaminant releasing ability; Sodium bicarbonate works the effect of washing that helps, and further improves detersive power; In prescription, adopt SPC-D, can discharge a kind of superoxide H
2O
2, bacterium there is stronger killing action, fabric there is bleaching, increases gorgeous effect, its water solubility height with other composition synergy, makes the existing stronger decontamination contaminant releasing ability of this product, sterilization and disinfection preferably.
Every indexs such as product detersive power of the present invention reach and surpass national standard, the washes discharging realizes 100% no phosphatization, material therefor is biodegradable, environment is not formed any pollution, the kill bacteria ability is up to more than 95%, and is non-stimulated to human body, no cumulative toxicity effect, safe and harmless to harmless, the no burn into life-time service of fabric and vessel, be the extensive disinfecting cleaning articles for use of the scope of application.
Embodiment:
The present invention can implement by following prescription:
Embodiment 1. title material consumptions (%) two sodium polysilicates 30 sodium polyacrylates 4 tweens 20 anion active agents 4 SPC-D 20 sodium bicarbonates 10 whitening agent, essence trace sodium sulfate 12
Embodiment 2. title material consumptions (%) two sodium polysilicates 10 sodium polyacrylates 10 tweens 10 anion active agents 10 SPC-D 8 sodium bicarbonates 30 sodium sulfate 22 whitening agent, essence trace
Embodiment 3. title material consumptions (%) two sodium polysilicates 15 sodium polyacrylates 8 tweens 15 anion active agents 8 SPC-D 10 sodium bicarbonates 20 sodium sulfate 28 whitening agent, essence trace
In implementation process of the present invention, the consumption of two sodium polysilicates is preferably: 15-30% (weight percent); The consumption of sodium polyacrylate is preferably: 5-10% (weight percent).
The present invention does not detect total Vanadium Pentoxide in FLAKES through the check of Sichuan Province's daily chemical product quality monitoring testing station, and detersive power meets the requirement of 13174 couples of non-phosphide detergent WL--B of standard GB type greater than 1.0.
