Amino silicone oil is a modified silicone oil developed in the 1980s and mainly used for soft, fluffy, and smooth handle finishing. However, amino silicone oil cannot be used directly. It must be emulsified with an emulsifier before it can be used. Because amino silicone oil is used In the process of demulsification, oil floating, silicone oil spots and other problems
In addition, amino silicone oil contains chemical components such as formaldehyde, NP / APEO and heavy metals, which have high pollution
[0003] In recent years, block silicone oil, which replaces amino silicone oil products, has gradually become popular in the market. However, due to the complicated synthesis process and the dependence on imported raw materials, the quality of block silicone oil on the market is unstable and the cost is high.

Abstract
The invention discloses block hydrophilic silicon oil, in particular discloses formula and synthesis process of novel block hydrophilic silicone oil. The invention aims to provide a formula and synthesis process of a novel block hydrophilic silicone oil, which are low in manufacturing cost, simple in process and environment-friendly. According to the formula, the novel block hydrophilic silicone oil comprises aliphatic polyethenoxyamine isopropanol, epoxy-terminated silicon oil, 20% sulfuric acid solution, dipropylene glycol, isooctanol polyethenoxy ether and glacial acetic acid. The production process is simple, the prepared block hydrophilic silicone oil manufactured is linear multiblock modified organic siloxane, and epoxy, polyether, amine group and the like are intercalated in the molecule main chain of the block hydrophilic silicone oil, and the prepared block hydrophilic silicone oil is particularly used for softness after-finishing of various loose wool, yarns, textiles and fabrics of polyester, nylon, nitrile, blended wool and nitrile, purified cotton and the like; in addition, the prepared environment-friendly swelling agent does not contain chemical components such as formaldehyde, NP / APEO (alkylphenol ethoxylates) and heavy metal, thereby being very environment-friendly.
Description
technical field [0001] The invention relates to a block hydrophilic silicone oil, in particular to a formula and a synthesis process of a novel block hydrophilic silicone oil. Background technique [0002] At present, amino silicone oil is required in the hand finishing agents of textiles on the market. Amino silicone oil is a modified silicone oil developed in the 1980s and mainly used for soft, fluffy, and smooth handle finishing. However, amino silicone oil cannot be used directly. It must be emulsified with an emulsifier before it can be used. Because amino silicone oil is used During the process, it is easy to break emulsion, float oil, and produce silicone oil spots and other problems. In addition, amino silicone oil contains chemical components such as formaldehyde, NP / APEO and heavy metals, which are highly polluting. [0003] In recent years, block silicone oils that replace amino silicone oil products have gradually become popular in the market. However, due to t...
