Epoxy silicone oil
Epoxy silicone oil is an important organic silicon polymer material, which is prepared by attaching a softener with epoxy groups to the side or end chains of silicone oil molecules. This special structure endows epoxy silicone oil with many excellent properties, making it widely used in many fields.

There are two main methods for preparing epoxy silicone oil: one is the addition reaction between hydrogen containing silicone oil and epoxy containing olefin, and the other is the substitution reaction between chlorosilane terminated polysiloxane intermediates and glycidyl ether. Among them, the SiOC bonds in the epoxy silicone oil produced by the latter are unstable, and the fatty epoxy groups are easily decomposed and lost from the main chain of the silicone oil when exposed to water. Therefore, attention should be paid to its stability when applied.


Epoxy silicone oil has extremely high reactivity. As a finishing agent for fiber fabrics, it can react with hydroxyl, amino, or carboxyl groups on the fiber surface, giving the fiber fabric a long-lasting soft effect. At the same time, the finished fabric is washable, non yellowing, and has a long-lasting waterproof finishing effect. In addition, epoxy silicone oil can be used in combination with amino modified silicone oil to further improve the hand feel, giving the fibers a wool like feel while also having anti shrink and anti wrinkle properties.


In the textile industry, the use of epoxy silicone oil as a softener can significantly improve the softness and comfort of fabrics. In addition, it can also be used for the finishing of materials such as leather and paper, improving their softness and smoothness. In the coatings industry, epoxy silicone oil can be used as a modifier to improve the adhesion and durability of coatings.


However, epoxy silicone oil also has some limitations. For example, its smoothness is relatively poor and needs to be compounded with other silicone oils to achieve optimal results. In addition, stability issues should be taken into account during the preparation and use of epoxy silicone oil to avoid its decomposition and loss of activity.


Overall, epoxy silicone oil, as an important organic silicon polymer material, has broad application prospects in fields such as textiles, leather, paper, coatings, etc. With the continuous advancement of technology and the increasing demand of people, the application fields of epoxy silicone oil will become more extensive, and its performance will also be more excellent.
