Description

Multi-purpose environmental protection concentrates detergent powder

The invention belongs to a kind of multi-purpose environmental protection concentrated detergent.

At present, the general cleaning agent promoting agents that adopt are alkylbenzene sulfonates more, no matter be to use tetrapropylenebenzene sulfonate or linear alkylbenzene sulfonate, after flushing, still can be adsorbed with the micro residue tensio-active agent, except that skin is damaged, to being adsorbed in the linear alkylbenzene sulfonate in the clothing, can be dissolved when perspiring come out, easily cause skin inflammationes such as eczema, also can be absorbed by the body by skin causes liver disease, cancer etc.; Sewage after the flushing also can pollute simultaneously, influences the balance of the mankind and ecotope.The auxiliary agent of most of cleaning agent adopts tripoly phosphate sodium STPP, pore forming material is used ammoniac compounds more, these are phosphorous, the cleaning agent of nitrogen is one of major reason that causes the water quality eutrophication, general detergent powder is owing to be rich in phosphorus nitrogen, cause environment to be subjected to severe contamination: thereby, people press for the washing agent of a kind of safety, environmental protection to the use worry Zhong Zhong of these synthetic detergents.

Purpose of the present invention is that the multi-purpose environmental protection that provides the superior biodegradability of a kind of tool, tool to clean remains of pesticide and strong detergency concentrates detergent powder.

The present invention is flowed compositions such as sour sodium, Fatty acid methyl ester carbonate, sodium polyacrylate, citric acid, Trisodium Citrate, water glass, yellow soda ash, SPC-D, saltcake, carboxymethyl cellulose, water and combines by lauryl alcohol, its prescription is (weight %):

1. lauryl alcohol flows sour sodium 18～22

2. Fatty acid methyl ester carbonate 13～17

3. sodium polyacrylate 8～12

4. citric acid 0.5～1

5. Trisodium Citrate 2～3

6. water glass 13～17

7. yellow soda ash 13～17

8. SPC-D 8～10

9. saltcake 10～15

10. carboxymethyl cellulose 1～2

11. water 1～1.5

Characteristics of the present invention are:

One, do not use alkylbenzene sulfonate to make tensio-active agent.Tensio-active agent of the present invention is to adopt by the natural coconut oil hydrogenation to generate the coconut oleyl alcohol, flow sour sodium and Fatty acid methyl ester yellow soda ash composition through the lauryl alcohol that sulfonation adds in the alkali and the back generates, its biological degradability is good, the U.S. ion of energy chelating calcium, anti-hard water is strong, detersive power is good, can give fabric certain flexibility, and other promoting agent is had solublization.

Two, the toxicity that can decompose the agricultural chemicals organophosphorus is alleviated heavy metal poisoning.The interworking coordinative role of the present invention's citric acid, Trisodium Citrate, Fatty acid methyl ester carbonate, use other auxiliary agent (cooperation of water glass and yellow soda ash) again, the organophosphorus pesticide of severe toxicity can be decomposed into nontoxic phosphoric acid salt, so the present invention can be used to wash fruit and thin dish, to prevent pesticide intoxication.

Three, be without phosphorus nitrogen detergent powder.Mostly the without phosphorus cleaning agent of developing at present is to replace tripoly phosphate sodium STPP with one or both auxiliary agents (as zeolite-water glass etc.), because these auxiliary agents detersive power separately is all not as good as tripoly phosphate sodium STPP, thereby influences its result of use.Auxiliary agent of the present invention is to select various ingredients for use, the detersive power of its combination after tested, and it is formulated to find the best proportioning that can replace tripoly phosphate sodium STPP to carry out, thereby strong detergency of the present invention.

The present invention needn't carry out the dried powder that indirect heating just can produce even matter, and equipment is succinct, can not produce waste gas, waste water during manufacturing, saves electric power, meets the requirement of environmentally-friendly sanitary.

Embodiments of the invention are as follows:

One, the weight percent of each component is chosen as follows:

1. lauryl alcohol flows sour sodium 20.0%

2. Fatty acid methyl ester carbonate 14.0%

3. sodium polyacrylate 10.0%

4. citric acid 0.5%

5. Trisodium Citrate 2.0%

6. water glass 13.0%

7. yellow soda ash 13.0%

8. SPC-D 10.0%

9. saltcake 15.0%

10. carboxymethyl cellulose 1.0%

11. water 1.5% 2, manufacturing processed:

The first step is poured 0.5% citric acid in 1.5% the water and is stirred to dissolving, and water temperature is controlled at about 60 ℃, when solution becomes limpid by milkiness, adds Trisodium Citrate again and stirs five minutes, forms citric acid solution;

Second step, 20% lauryl alcohol is flowed sour sodium and 14% Fatty acid methyl ester carbonate places separately in the stirrer, mix stir five minutes evenly after, slowly add citric acid solution again;

In the 3rd step,, make it to become colloid with stirring 5～10 minutes in 10% sodium polyacrylate, the 1.0% carboxymethyl cellulose adding citric acid solution;

In the 4th step, 13% water glass, 13% yellow soda ash and 1.0% saltcake are mixed stirring at big stirrer;

The 5th step, the 3rd jelly that goes on foot gained is added big stirrer to be mixed with the mixture of the 4th step gained, and the speed stir about that changes with per minute 48～80 30 minutes, because oil rubs mutually and reacts with opaque, can produce heat this moment, so the control stirring velocity is very crucial, can produce caking phenomenon when temperature is too high:

The 6th step added 10% SPC-D and stirred 10 minutes, promptly made this product.
