Abstract
The invention discloses a preparation method of laundry detergent. The preparation method comprises the following steps of adding the following components (in parts by weight) into a reaction kettle: 10-15 parts of 4A zeolite powder, 5-8 parts of soda powder and 2-6 parts of sodium dodecyl benzene sulfonate. The preparation method has the beneficial effects that the laundry detergent prepared by utilizing the preparation method is low in production cost, has no toxic and side effects, is rapidly dissolved, is low in dosage and strong in dirt-removing power, can be used for effectively removing various stains, is suitable for the washing of various water qualities, has sterilizing and whitening effects and mild performance, and can not hurt hands and cloth; a test proves that a washing effect of the laundry detergent is improved by 30%-35% than that of the existing non-phosphorus laundry detergent; the re-deposition of the stains can be effectively reduced, and the softness of the clothing is beneficially maintained; foams are moderate, a rinsing process is simple, and the water and labor are saved; by utilizing an environmentally-friendly formula, the degradation rates of raw materials are high, and the secondary pollution to the environment is avoided.
Description
Technical field
The preparation method who the present invention relates to a kind of washing powder, belongs to filed of daily-use chemical industry.
Background technology
At present commercially available regular powder is because containing a certain amount of phosphoric acid salt, and the waste liquid after washing enters rivers Hai Hu makes pasture and water suddenly long, and part rivers Hai Hu is nearly all in anoxic condition.Cause this class to pollute, make the mankind's environmental quality produce grave danger: wherein to have a kind of blue-green algae can produce toxin, serious harm HUMAN HEALTH.Non-phosphide detergent is the improved important directions of existing washing powder, some non-phosphide detergents also add sodium-chlor increases the sterilizing function of washing powder, but in general, these washing powder soil removabilitys are not strong, wash degree is not good, and the washing powder amount that need to add when washing clothes is larger, and raw materials cost own is also higher, owing to there are above-mentioned problems, cause non-phosphide detergent to be made slow progress aspect popularization.
Summary of the invention
The deficiency existing for prior art, technical problem to be solved by this invention is, a kind of preparation method of washing powder is provided, the washing powder that uses this method to prepare is not phosphorous, free from environmental pollution, cheap.
For solving the problems of the technologies described above, the technical scheme that the present invention takes is that a kind of preparation method of washing powder, comprises the following steps:
(1) following material (calculating by weight) is added in reactor: 4A zeolite powder 10-15 part, soda powder 5-8 part, Sodium dodecylbenzene sulfonate 2-6 part;
(2) in said mixture, add deionized water 25-35 weight part, then stir, stirring velocity 25-35 rev/min, heats in whipping process, Heating temperature 45-65 degree Celsius;
(3) mixture after heating is left standstill, time of repose is greater than 35 minutes;
(4) in the mixture after leaving standstill, add sodium sulfate 5-10 weight part, soda ash 2-4 weight part, tallow fatty acid sodium sulfate 1-2 weight part and deionized water 15-25 part, in adition process, stir, stirring velocity is 25-35 rev/min;
(5) stir and heat later, leave standstill 35-50 minute after heating, Heating temperature is 50-60 minute;
(6) leave standstill after filter, filtration velocity is 2-6 liter/min;
(7) after filtration, put into low-temperature heat machine, carry out oven drying at low temperature, dry to solid;
(8) solid is put into pulverizer, pulverize.
Optimize, the preparation method of above-mentioned washing powder, the size of powder particles in its step (8) is 120-200 order.
Beneficial effect of the present invention is: the washing powder low production cost of producing by method of the present invention, has no side effect; Dissolve fast, low-consumingly, soil removability is strong, effectively removes various spots, is applicable to various water quality washings; There is sterilization, whitening efficacy, performance gentleness, do not hinder hand, do not hinder clothes, the experiment proved that, washing effect and existing non-phosphide detergent comparison, clothing wash degree improves 30%-35%; Can effectively reduce spot and deposit, it is submissive that favourable clothing keeps; Moderate foam, rinsing is easy, and water-saving is laborsaving; Employing environmental protection formula, raw material degradation rate is high, does not have secondary environmental pollution.
