Abstract
The detergent capable of use in highly hard sea water is comprised of (wt. proportions) 7-14 parts of fatty alcohol polyoxyethene ether, 5-12 parts of fatty alcohol ether sodium sulfate, 1.5-3.5 parts of sodium sulfate lipolic alcohol, 20-30 parts of sodium triphosphate, 30-40 parts of sodium pyrophosphate, 6-15 parts of sodium carbonate, 7.5-15 parts of sodium metasilicate, 1-5 parts of sodium carboxy methyl cellulose and 0.05-0.2 part of whitening agent.
Description
The present invention relates to an improvement of clothes detergent, and is a clothes detergent resisting high-hardness water and seawater.
At present, common soap, common washing powder or super concentrated washing powder and the like are mainly suitable for washing clothes in fresh water. For fishermen working on the sea and naval officials or other workers performing tasks, fresh water required by ships is mainly edible, limited drinking water is difficult to be used for washing clothes, if the clothes cannot be washed completely by using the seawater, and because a large amount of inorganic salt exists in the seawater, especially the content of calcium and magnesium ions is high (the water hardness is as high as 6300ppm and is 20-40 times higher than that of ordinary water), a large amount of water-insoluble calcium and magnesium soap scum is generated and deposited on the surface of fiber fabrics, so that the clothes are yellow, hard and unclean.
The invention aims to provide a cleaning agent suitable for washing clothes with high hardness such as seawater and the like in order to overcome the defects.
The detergent formula for achieving the purpose of the invention is as follows: the preparation method comprises the steps of firstly melting fatty alcohol polyoxyethylene ether at 40-60 ℃ for later use, uniformly mixing the sodium tripolyphosphate, the sodium carbonate, the sodium metasilicate, the sodium carboxymethylcellulose, the whitening agent and the fatty alcohol sodium sulfate, injecting molten liquid fatty alcohol polyoxyethylene ether and the fatty alcohol ether sodium sulfate at normal temperature, uniformly mixing, stirring, and aging to obtain the product.
The detergent is prepared by compounding various surfactants, calcium soap dispersant, calcium-magnesium ion chelating agent and builder, has good functions of lubrication, emulsification, foaming, dispersion, solubilization and the like, has obvious effect of removing dirt on clothes, and softens high-hardness water to improve the dirt-removing capacity. The preparation method is simple and the application range is wide; the seawater can be used for washing clothes and cleaning mechanical parts. Has no irritation to skin, no damage to fabric, and no adverse side effects.
The sodium metasilicate in the invention can be sodium metasilicate pentahydrate or sodium metasilicate nonahydrate, and can also be anhydrous sodium metasilicate. 4.5-6 parts of anhydrous sodium sulfateand 0.1-0.2 part of essence can be added into the original formula to carry out the formula in order to improve the sensory index of the product. In the formula, the fatty alcohol ether sulfate and the fatty alcohol-polyoxyethylene ether have double functions, namely, the fatty alcohol ether sulfate is a surfactant and is also a lime soap dispersing agent; sodium polyphosphate and sodium pyrophosphate are used as chelating agents in the formula to chelate hardy metal ions in water so as to have the capability of softening the water. Reacting the hard metal ions with two or more sodium ions in the phosphate molecule by complex decomposition into the anions of the molecule, the ionic formula of which is: in this case, the magnesium ions lose their original function and are chelated, and no further ions are involvedAnd (4) reacting. The surfactant fatty alcohol-polyoxyethylene ether can also be nonylphenol polyoxyethylene ether or fatty alcohol-polyoxyethylene ether and nonylphenol polyoxyethylene ether. The anti-re-settling agent is sodium carboxymethyl cellulose, carboxymethyl cellulose starch, hydroxypropyl methyl cellulose, hydroxybutyl methyl cellulose and alkyl pyrrolidone. Brightener refers to fluorescent whitening agent (model number VBL, BSL, CBS-X).
Example (b):
1. melting 11 parts of fatty alcohol-polyoxyethylene ether at 50-60 ℃, and then putting 25 parts of sodium tripolyphosphate, 9 parts of sodium carbonate, 10 parts of sodium metasilicate nonahydrate, 4.7 parts of sodium sulfate, 30 parts of sodium pyrophosphate, 1 part of sodium carboxymethyl cellulose, 0.1 part of whitening agent and 2 parts of sodium fatty alcohol sulfate into a high-speed mixer for premixing for 5-10 seconds to ensure that the mixture is uniform. Then pumping (or injecting) the molten fatty acid polyoxyethylene ether liquid into the mixer through a nozzle to be absorbed on the surface of the powder, and quickly adding 7 parts of fatty alcohol ether sodium sulfate and 0.2 part of essence to spray the mixture on the powder. And (4) continuing stirring for 10-20 seconds after the above process is finished, and discharging the materials in the mixer into an old generation tank for aging for 5 hours to obtain the product.
2. 25 parts of sodium tripolyphosphate, 10 parts of sodium carbonate, 7.5 parts of sodium metasilicate, 35 parts of sodium pyrophosphate, 2 parts of carboxymethyl cellulose starch, 0.15 part of whitening agent and 2.5 parts of fatty alcohol sodium sulfate are placed in a high-speed mixer by weight, are stirred for 5-10 seconds, and then liquid fatty alcohol polyoxyethylene ether is injected through a nozzle, and simultaneously, fatty alcohol ether sodium sulfate is rapidly added to be sprayed to powder. The rate of liquid addition must be adjusted so that the liquid is absorbed as it reaches the powder surface. And after the liquid is completely added, continuously stirring for 10-20 seconds, unloading the materials in the mixer into an aging tank, aging for 4-24 hours, and packaging.
