Problems solved by technology

However, there are sometimes large quality differences between the multi-batch softener products obtained by this method, mainly due to the large deviation in viscosity, so this method is not stable.
The inventor finds that the density difference of quaternary ammonium salt and polyethylene glycol distearate is relatively large, and its molten mixture cannot be kept uniform for a long time, and precipitation will be arranged, so that the difference between quaternary ammonium salt and polyethylene glycol distearate between different batches of softener products There are differences in the ratio of diol distearate, which eventually leads to unstable quality of softener products
[0005] Quenching the molten mixture to make it solidify quickly helps to improve the above problems, but the introduction of quenching equipment will increase the production cost and make the production process more complicated

Embodiment 1

[0043] Softener product raw material preparation

[0044] Dioctadecyl dimethyl ammonium chloride raw material was sliced ​​at a temperature of 25°C (the size of the slice was not more than 2×2cm, and the thickness was not more than 1mm), and polyethylene glycol was added in proportion (95:5) -150 bis-stearic acid solid (powder, molecular weight 6000), ready for use after simple mixing.

[0045] Softener product preparation

[0046] Control the water temperature at 55°C, add 0.15% of the total amount of softener to the finished product, and add 1% pigment (solvent is water), disperse completely, and keep the water temperature at 55-60°C during this period, then add the softener while stirring The total amount of the finished product is 5% of the raw materials of the above softener product. Stir while using a water bath of 55°C-60°C to keep the temperature at about 55-60°C. After stirring and dispersing completely, cool down to 25°C and add essence. Detect its viscosity, with ...

Embodiment 2

[0057] Prepare 3 parts of softener raw materials according to the same proportioning and process as in Example 1.

[0058] Control the water temperature at 50°C, add 0.15% of the total amount of the finished softener and add 1% of the pigment (solvent is water), and disperse completely. During this time, the water temperature remains at 50°C, and then add 0.15% of the total amount of the softener. For softener product raw materials with an amount of 5%, keep the temperature at 50°C while stirring. After stirring and dispersing completely, cool down to 25°C and add essence. Detect its viscosity, with a viscosity of 1800-2500 as a qualified product.

[0059] Process parameter and viscosity of table 4 embodiment 2 products

[0060]

[0061] The raw materials of M1, M2 and M3 are prepared in the same way as the raw materials used in Example 1. After lowering the water temperature, the viscosity of the softener finished product does not change significantly, and is within the r...

Abstract

The invention relates to a raw material of a softening agent product, which comprises 50-99.9% of quaternary ammonium salt solid and 0.1-50% of thickener solid based on weight. The raw material can be used to product the softening agent product with stable quality. The invention also provides a use of the raw material of the softening agent product for preparing the softening agent product, and a preparation method of the softening agent product with the raw material of the softening agent product. By virtue of the raw material, the production time of the softening agent product is effectively shortened; the production cost is reduced; and the stability of the production process is improved.

Description

technical field [0001] The invention belongs to the field of softeners, and in particular relates to a softener product raw material and a method for preparing softener products from the softener product raw material. Background technique [0002] In southern Europe, South America, Southeast Asia and northern China, consumers are accustomed to using thicker softener products, so softener products will contain softeners (such as quaternary ammonium salts) and thickeners (such as polyethylene glycol distearate). [0003] Chinese patent application CN200910205261.6 describes a preparation method of a softener product, which first melts the quaternary ammonium salt and polyethylene glycol distearate and mixes them respectively, and then adds the mixture into water to fully disperse it to obtain a softener product. agent products. [0004] In production, in order to facilitate operation, usually a large amount of quaternary ammonium salt and polyethylene glycol distearate are m...
