Problems solved by technology

The selection of emulsifier increases the cost of this type of softener
[0004] Although the commonly used amino-modified silicone softener has a good softening effect, its whiteness, water absorption, and easy decontamination are poor, and it will become more serious with the increase of amino functional groups in the polymer.

Embodiment 1

[0028] Step (1): Weigh 6 parts of amino-modified silicone oil and 30 parts of distilled water into a three-necked flask, and stir in a water bath.

[0029] Step (2): compound emulsifier: add fatty alcohol polyoxyethylene ether, alkylphenol polyoxyethylene ether and fatty alcohol surfactant in a certain weight ratio (2:2:1) to the beaker.

[0030] Step (3): Add the emulsifier in step (2) into the amino-modified silicone oil, and stir until evenly dispersed.

[0031] Step (4): Then quickly drop 0.25 parts of glacial acetic acid solution while stirring the solution, and then add 8 parts of glycerin after the dropping, and react for half an hour to obtain a silicon-containing softener.

Embodiment 2

[0033] Step (1): Weigh 6 parts of amino-modified silicone oil and 33 parts of distilled water into a three-necked flask, and stir in a water bath.

[0034] Step (2): compound emulsifier: add fatty alcohol polyoxyethylene ether, alkylphenol polyoxyethylene ether and fatty alcohol surfactant in a certain weight ratio (3:3:1) to the beaker.

[0035] Step (3): Add the emulsifier in step (2) into the amino-modified silicone oil, and stir until evenly dispersed.

[0036] Step (4): Then, while stirring the solution, quickly add 0.3 parts of glacial acetic acid solution dropwise, and then add 8 parts of glycerin after the dropwise addition, and react for half an hour to obtain a silicon-containing softener.

Embodiment 3

[0038] Step (1): Weigh 7 parts of amino-modified silicone oil and 36 parts of distilled water into a three-necked flask, and stir in a water bath.

[0039] Step (2): compound emulsifier: add fatty alcohol polyoxyethylene ether, alkylphenol polyoxyethylene ether and fatty alcohol surfactant in a certain weight ratio (3:3:1) to the beaker.

[0040] Step (3): Add the emulsifier in step (2) into the amino-modified silicone oil, and stir until evenly dispersed.

[0041] Step (4): Then quickly dropwise add 0.35 parts of glacial acetic acid solution while stirring the solution, and then add 9 parts of glycerin after the dropwise addition, and react for half an hour to obtain a silicon-containing softener.

Abstract

The invention discloses a preparation method of a silicon-containing softening agent for a facial tissue and application thereof. The softening agent comprises the following raw materials in parts byweight: 6-10 parts of amino modified organic silicone oil, 1.5-2 parts of alkyl phenol polyoxyethylene ether, 1.5-2 parts of fatty alcohol polyoxyethylene ether, 0.5-1 part of a fatty alcohol surfactant, 8-10 parts of glycerol, 30-40 parts of distilled water and 0.25-0.5 part of glacial acetic acid. The preparation method of the softening agent primarily comprises the following steps of adding a compound nonionic emulsifier into the amino modified organic silicone oil; adjusting the pH value of a solution by means of the glacial acetic acid; increasing the flexibility of the solution by meansof glycerol; and manufacturing a novel silicon-containing softening agent by steps of stirring, heating and the like. The prepared softening agent is environment-friendly and pollution-free, simple informing process and rich in material source, has good flexibility, hydrophilcity, compatibility and appropriate rheological property and is beneficial for industrial production. The facial tissue canbe endowed with excellent flexibility and wet strength by Meyer coating.

Description

technical field [0001] The invention relates to the field of facial tissue auxiliaries, in particular to a method for preparing a silicon-containing softener for facial tissue. Background technique [0002] Softeners are the most commonly used additives in chemical processing, and their main function is to reduce the friction coefficient between fibers to obtain soft and lubricating effects. The part that causes softness is mainly the long-chain alkyl group of the softener, which is called lipophilic or hydrophobic group because it retains the properties of oil, and has a hydrophilic group at its end, which can form hydrogen bonds with cellulose molecules and make it The softener molecule is adsorbed on the fiber, so the softener has good softness and wet strength. It can be used as a non-durable softening finishing agent, and can also be used as an important component of synthetic fiber spinning oil. Among them, silicone softeners are favored due to their unique structure ...
