Problems solved by technology

The phosphorus-substituting additives in the current phosphorus-free laundry detergent are basically 4A zeolite system. The biggest disadvantage of 4A zeolite is that it is insoluble in water, resulting in low efficiency of chelating calcium and magnesium ions in water, and may also cau

Embodiment 1

[0013] (1) Take 160 parts of sodium dodecylbenzenesulfonate, 200 parts of light sodium carbonate, 100 parts of anhydrous sodium metasilicate, 20 parts of disodium edetate, 2 parts of fluorescent whitening agent, and Put 157 parts of starch powder in a ribbon mixer and mix and stir for 2-3 minutes to obtain semi-finished product A1.

[0014] (2) Take another 330 parts of fatty alcohol polyoxyethylene ether AEO-330 and 940 parts of fatty alcohol polyoxyethylene ether AEO-940 and heat it to a molten state, add 1 portion of lemon essence into the molten substance, and stir evenly to obtain a mixture B1 .

[0015] (3) Under the condition of stirring, add 40 parts of acrylic acid-maleic acid copolymer sodium salt, 250 parts of alkyl modified dicarboxylate polymer and mixture B1 to the semi-finished product A1, and stir until all the liquid ingredients All of them are absorbed into dry powder and granules, and this washing powder is obtained.

Embodiment 2

[0017] (1) Take 150 parts of sodium dodecylbenzenesulfonate, 210 parts of light sodium carbonate, 110 parts of anhydrous sodium metasilicate, 25 parts of disodium edetate, 3 parts of fluorescent whitening agent, and 165 parts of starch powder were placed in a ribbon mixer and mixed for 2-3 minutes to obtain semi-finished product A2.

[0018] (2) Take another fatty alcohol polyoxyethylene ether AEO-325 parts and fatty alcohol polyoxyethylene ether AEO-935 parts and heat it to a molten state, add 2 parts of lemon essence into the molten substance, and stir evenly to obtain a mixture B2 .

[0019] (3) Add 35 parts of acrylic acid-maleic acid copolymer sodium salt, 240 parts of alkyl-modified dicarboxylate polymer and mixture B2 to the semi-finished product A2 under stirring conditions, and stir until all liquid components All of them are absorbed into dry powder and granules, and this washing powder is obtained.

Embodiment 3

[0021] The present invention replaces STPP and 4A zeolite with the comparison of the decontamination ability of similar products at home and abroad, taking the standard washing powder as the benchmark, and the decontamination effect is shown in Table 1.

[0022]

[0023] Table 1

[0024] As shown in the experimental results in Table 1, after the present invention cancels the 4A zeolite system, the decontamination ability of the new phosphorus substitute additive has a very good performance. The decontamination ability remained basically the same.

Abstract

The invention discloses a formula of phosphate-free detergent. The phosphate-free detergent is prepared from 150-170 parts of sodium dodecyl benzene sulfonate, 185-220 parts of light sodium carbonate, 95-115 parts of anhydrous sodium metasilicate, 32-46 parts of acrylic acid-maleic acid copolymer sodium salt, 15-28 parts of disodium ethylenediamine tetraacetate, 230-270 parts of alkyl modified dicarboxylate polymers, 1-3 parts of a fluorescent whitening agent, 145-170 parts of anhydrous sodium sulphate, 20-40 parts of fatty alcohol-polyoxyethylene ether AEO-3, 30-50 parts of fatty alcohol-polyoxyethylene ether AEO-9 and 1-2 parts of lemon essence. The phosphate-free detergent of the formula can effectively overcome the defect of a phosphate-substituted additive of existing phosphate-free detergent, and chelate most calcium, magnesium and iron ions in water, the effect is far better than that of a current 4A zeolite system, and the phosphate-free detergent has the advantages of being good in hard water resistance, capable of being dissolved fast, high in detergency, mild, free of stimulation and the like; moreover, the price of the phosphate-substituted additive in the phosphate-free detergent of the formula is lower than that of the 4A zeolite system, the phosphate-substituted additive is convenient to use and popularize on a large scale, and is the new direction of detergent phosphate-free additives in the future.

Description

technical field [0001] The invention relates to a phosphorus-free washing powder, which belongs to the field of daily chemical industry. Background technique [0002] Washing powder is our daily necessities. Washing powder is divided into phosphorus-containing washing powder and phosphorus-free washing powder. Phosphorus-containing washing powder uses phosphate as the main auxiliary agent, and phosphorus is easy to cause eutrophication of environmental water bodies, thereby destroying water quality. polluted environment. Phosphorus-free washing powder does not have this shortcoming, which is beneficial to the protection of the water body environment. For the health of our living environment, it is recommended to use phosphorus-free washing powder. The phosphorus-substituting additives in the current phosphorus-free laundry detergent are basically 4A zeolite system. The biggest disadvantage of 4A zeolite is that it is insoluble in water, resulting in low efficiency of chela...
