Fatty acid alkyl amide 0.5～2%.
Each composition weight percent of the compound washing assistant of the present invention is:
Sodium polyacrylate 1～5%
Water glass 1～10%
Yellow soda ash 5～20%.
Manufacturing process of the present invention adopts the attached polymer molding technology, and specific operation process is: at room temperature the solid powder that separated pulverizing is good is dropped into powder by metering and give in the mixed device, mixed 3～15 minutes, powder is mixed; Liquid material is given in the mixed pot by being metered into liquid, make the logical vapour of interlayer be warmed up to 40～60 ℃, mixed 5～10 minutes, liquid material is mixed.Then with the solid powder that mixes by being metered in the Conicaldoublewormmixer, start the back duplex and carry out rotation revolution (two asymmetric screw shaft rotations in the mixing machine after 2～10 minutes, material is upwards promoted, form asymmetrical along cylinder body tube arm stud-shape streams from bottom to top, drive the spiral revolution by pivoted arm more simultaneously, along cylindrical shell wholecircle Zhou Fangwei running, reach the continual renovation diffusion of wholecircle Zhou Fangwei material.Like this, owing to rotation revolution planetary motion forms the material convection circulation.), will give mixed liquid material constant speed atomisation equably by the measuring fixed amount liquor pump, be sprinkled upon on the moving powder, carry out agglomeration, granulating and forming 3～15 minutes sprays into forming agent and essence (trace) at last, reruns shutdown, discharging 2-5 minute.Obtain even phosphate-free and aluminum-free washing powder product after making molding materials by the screening of ternary vibrating screener again.
The advantage that the present invention compared with prior art has is:
The present invention selects for use nonionogenic tensides such as anion surfactant such as α-sodium olefin sulfonate, sodium lauryl sulphate, sodium soap soap powder and aliphatic alcohol polyethenoxy (9) ether, alkylphenol-polyethenoxy (10) ether, fatty acid alkyl amide collaborative composite, has replaced sodium alkyl benzene sulfonate.α-sodium olefin sulfonate LD
50=3.26g/kg belongs to No Poison (this sodium sulfonate of alkyl LD
50=1.62g/kg), to skin non-stimulated (content is in 10% coating test-results), action temperature and, biodegradation rate is fast, the disappearance of can degrading fully in five days (sodium alkyl benzene sulfonate after month still residual 30%), and detersive power also is better than sodium alkyl benzene sulfonate, especially in hard water, when hardness equaled 100mg/kg, decontamination was higher than sodium alkyl benzene sulfonate (65%) far away still up to 83%.Excellent in importantly being that it and fatty acid sodium soap coupling can be solubilized in the water altogether, test-results is as follows:
α-olefin sulfonic acid sodium content (%) fatty acid sodium soap solubleness in water increases (%)
2 17.3
4 20.3
5 22.7
6 24.7
8 27.0
10 31.6
15 48.4
20 74.4
Therefore, α-sodium olefin sulfonate and action temperature and, be that biological degradation is nontoxic, but solubleness is little in water, the fatty acid sodium soap that easily forms soap scum in hard water is composite, will give full play to the fatty acid sodium soap advantage and significantly reduces its shortcoming, again with fully biodegradable, strong detergency, the good No Poison sodium lauryl sulphate of cold washing constitutes jointly anion surfactant family.The present invention simultaneously selects for use anti-hard water to deoil, and dirt is strong, wettability is good, but the nonionogenic tenside family that nonionogenic tenside aliphatic alcohol polyethenoxy (9) ether of cold washing, alkylphenol-polyethenoxy (10) ether and fatty acid alkyl amide are formed.Like this, the a small amount of nonionogenic tenside of adding family in anion surface activity family, anion surfactant ion head mutual expelling force is reduced, van der Waals' force between hydrophobic base key strengthens, impel capsule to be easy to form, make critical capsule concentration reduce the capsular formation of this mixing, produce best synergistic effect, thereby replaced sodium alkyl benzene sulfonate.
It is to be made of sodium polyacrylate, water glass and yellow soda ash that the present invention selects compound washing assistant for use, result of study shows, sodium polyacrylate (average molar mass: 6000～7000g/mol) just big 50～100 μ m dirt granule can be dispersed at lower concentration (20mg/L)＜below the 1 μ m, 50～100 μ m calcium soap scums are dispersed into＜below the 1 μ m, fine particle forms milk shape dispersion system like this, needn't precipitate, very easily rinsing.And tripoly phosphate sodium STPP can make the cohesion of dirt granule, and particle increases.It is acid that dirt generally is, the washing composition meta-alkalescence, and both neutralizations weaken washing lotion alkalescence, and the sodium polyacrylate resistance to acid is better than tripoly phosphate sodium STPP, can keep washing the system slight alkalinity, and reduce the lotion consumption.Different auxiliary agents are to the clean effect difference of different pollutents, and result of study such as table 1, table 1 are the clean effect comparisons of different auxiliary agents to different pollutents.
According to result of study, because sodium polyacrylate disperses the effect of dirt granule calcium soap scum by force, carbon black, Manganse Dioxide, kaolin are shown fine clean effect, but it is relatively poor that oily dirt is removed ability; Yellow soda ash since alkalescence show more by force Viscotrol C, removal effect that machine oil is strong; Water glass has the suspended dispersed effect because of hydrolysis in water medium can produce the silicic acid of capsule structure to dirt, and is good to the carbon black removal effect.Therefore, the present invention is with sodium polyacrylate, and yellow soda ash and water glass have carried out reasonable group of change, constitute compound washing assistant, and detersive power is improved greatly, can replace tripoly phosphate sodium STPP fully.Zeolite is made good use of carbon black, machine oil owing to its adsorption with to band coloring agent capsule dirt coagulation as can be known simultaneously, and this also is present non-phosphide detergent replaces tripoly phosphate sodium STPP with zeolite a reason.Yet zeolite is a silico-aluminate, is aluminum contained compound, and is harmful, also can get carefully sooner or later, and the present invention will not adopt.
Substrate is dipped in the medium because washing composition exists, make dirt and substrate surface bonding become dirt and combine with lotion, thereby dirt is broken away from and substrate surperficial and be suspended in the medium.Yet washing process is a reversing process, and the dirt that is suspended in the medium also might be redeposited in the substrate surface from medium, i.e. the redeposition process.The present invention complexed surfactant and compound washing assistant, under the prerequisite of phosphate-free and aluminum-free, reached the bonding force that has both reduced dirt and substrate surface, impel dirt to break away from the substrate surface, prevent to have washed off soil redeposition substrate surface simultaneously, made soil dispersion become milk shape dispersion, not only be difficult to deposition, and very easily rinsing, acquire strong detersive power (the decontamination ratio can reach more than 1.3～1.8 relatively).Also, in normal-temperature water, can dissolve fully because the outstanding combination of tensio-active agent of the present invention reduces best wash temperature.Washing powder concentration 2.5% pH value of solution value of the present invention is 7.5 ± 0.3, it is nearly neutral environment washing, and select for use tensio-active agent all to belong to low to stimulate non-stimulated product, thereby product of the present invention after measured to rabbit skin irritant reaction average integral in 0～0.31 scope, belong to the nonirritant product.Because this product selects for use raw material to be No Poison, through toxicity check, product LD of the present invention
50=9.26g/kg ± 0.20 (male mice), LD
50=7.94g/kg ± 0.20 (female mice), so product of the present invention is nontoxic product.
Manufacturing process of the present invention is easy, and is easy to control easy to operate, do not have the waste water and gas waste sludge discharge in manufacturing processed, thereby not only product is " green ", and to make production process also be green, is a cleaning project.After the present invention's product is used for laundry, discharging raffinate phosphate-free and aluminum-free, biological degradation has no adverse effects to environment rapidly and fully, is environmentally friendly machine.
