Problems solved by technology

In the prior art, the commonly used thickener is stearic acid, but stearic acid has a high melting point and requires a temperature above 70°C to melt, and its dispersibility is poor. Higher processing temperature and dispersion time increase Cost of production

Embodiment 1

[0032] 40g dioctadecyldimethylammonium methyl sulfate (VARISOFT 137 90, provided by EVONIK company) and 8g PEG-150 distearate (D638, provided by Daoming Chemical Co., Ltd., Guangzhou City, Guangdong Province) in Heat and pre-melt separately at 60-70°C. When the two raw materials are fluid, slowly mix the two raw materials evenly at 65°C under stirring, and avoid bubbles during the mixing process of 2-3 minutes to obtain a softener Raw material 48g.

[0033] Without a water bath, pour 48g of the softener raw material prepared above at about 20°C into 752g of water at 40°C under stirring conditions, stir for 40 minutes and mix evenly to obtain the softener product 1 of the present invention. The sample kept a low viscosity throughout the preparation process, and there was no phenomenon of climbing rods due to increased viscosity, nor did it suddenly become thinner. The product has a viscosity of 1900 cps.

Embodiment 2

[0035] With 40g dioctadecyldimethylammonium methosulfate (VARISOFT 137 90, provided by EVONIK company) and 4g PEG-150 distearate (D638, provided by Daoming Chemical Co., Ltd., Guangzhou City, Guangdong Province) in Heat and pre-melt separately at 60-70°C. When the two raw materials are fluid, slowly mix the two raw materials evenly at 65°C under stirring, and avoid bubbles during the mixing process of 2-3 minutes to obtain a softener Raw material 44g.

[0036] Without a water bath, pour 48g of the softener raw material prepared above at about 40°C under stirring conditions into 756g of water at 35°C and mix evenly. Observe after 10 minutes. At this time, the sample has no phenomenon of climbing poles at all. See image 3 . Continue stirring and mixing for 40 minutes to obtain softener product 2 of the present invention. The sample kept a low viscosity throughout the preparation process, and there was no phenomenon of climbing rods due to increased viscosity, nor did it sudde...

Abstract

The invention relates to a new method for preparing a softener product. The method comprises the following steps: (1) melting quaternary ammonium salt and polyglycol distearate respectively at 50-70 DEG C, mixing to obtain a softener raw material; and (2) directly adding the softener raw material water at 30-60 DEG C and stirring to mix. By adopting the method in the invention, the softener product containing quaternary ammonium salt, particularly, alkyl dimethyl quaternary ammonium salt can be effectively thickened and the production cost can be reduced. The invention also relates to the softener product prepared by the method; and the viscosity of the product (25 DEG C, 30rpm) is more than 500cps, and the optimum viscosity is more than 1000cps.

Description

technical field [0001] The invention relates to a new method for preparing softener products, in particular to a new method for preparing softener products containing quaternary ammonium salts. The invention further relates to softener products obtained by this process. Background technique [0002] In southern Europe, South America, Southeast Asia and northern China, consumers are used to using thicker softeners. Thickening the softener at a lower cost has become a problem that manufacturers need to solve. In the prior art, the commonly used thickener is stearic acid, but stearic acid has a high melting point and requires a temperature above 70°C to melt, and its dispersibility is poor. Higher processing temperature and dispersion time increase Cost of production. [0003] There is a need in the market for a method that can effectively thicken softener products containing alkyl dimethyl quaternary ammonium salts and reduce production costs. For the industrial production...
