Silicone oil is now widely used as a kind of silicone oil, the former silicone oil is not today so many functional characteristics.The production and application of silicone softener in China can be said to have experienced 4 generations. Xinjia Xiaobian will give you a brief introduction. 

    The first generation of

    It is a high molecular weight polysiloxane emulsion with hydroxyl end (hydroxyemulsion), which is made of octadecyclic tetrasiloxane (D4), water, emulsifier, catalyst and other raw materials under certain conditions.

    The second generation

    Polyether modified silicone oil is made of methyl hydrogen containing silicone oil and polyether with unsaturated bond at the end of polyethylene glycol, polypropylene glycol and other polyethers by silicon hydrogen addition reaction.

    The third generation

    Is the active group (amino group, epoxy group) of polysiloxane emulsion polymerization method and hydroxyl milk is basically the same, the difference is in the raw material added a certain amount of silane coupling agent.The introduction of these amino and epoxy functional groups has greatly improved the softness, smoothness, elasticity and durability of the finishing effect of the finished fabric. The disadvantage is that there are deemulsification and oil bleaching in the process of use.This kind of polysiloxane emulsion with active groups because of the use of ionic surfactant, the emulsion is strong cationic or anionic, and other additives when the combination of strong selectivity, poor compatibility.

    The fourth generation

    The modified silicone oil represented by amino silicone oil is the most representative silicone softener variety in the current market, usually we put the ammonia ethyl ammonia propyl polydimethylsiloxane called standard amino silicone oil, and the other ammonia substituted polysiloxane is called modified amino silicone oil.Amino silicone oil due to strong polarity of amino, and the surface of the fiber of hydroxyl, carboxyl interaction, and the formation of a very firm orientation, adsorption, the friction coefficient between the fibers decreased, which means that the fabric in the hand, with a small force can make the fiber began to slide, so that feel soft.

    In recent years, organic modified silicone oil has been rapidly developed, and there are many organic modified silicone oil with special properties.The development of organic modified silicone oil has experienced a long history of development, at present, there are many special properties, but this is not the end, silicone modified silicone oil is still developing, there may be more possibilities in the future.
