Silicone oil is usually kept in liquid state at room temperature linear polysiloxane products, generally they are colorless (yellow), tasteless, nontoxic, non volatile liquid. Their molecular weight is not high, at room temperature as a flow state, so it is usually called silicone oil. Generally it is not only, but through a special formula made, often used as auxiliary material to produce certain effect. In general, the silicone oil on the market has three basic forms: pure silicone oil, solution, emulsion.
First, pure silicone oil has very strong stability, heat resistance, antifreeze, storage is good, having a high flash point and high fire point, storage and transportation issues rarely.
Second, in fact often need to dilute the oil solution, sometimes in the hope of adding solution of active auxiliary agent (catalyst, cross-linking agent) for convenient storage and use, according to the need by using aliphatic, aromatic and chlorinated hydrocarbon as solvent, under special circumstances the use of other kinds of solvent, the general solution concentration polymer Polymer-siloxane solution, only have thirty five per, otherwise the viscosity is too big;
Third, the big part of silicone oil or silicone oil products are made with solvent silicone oil emulsion morphology, it is cheap, in contrast, is not easy to burn, harmless to health etc. And solvent type different, all silicone emulsions are” oil-in-water” type non homogeneous system, its external closure phase aqueous, silicone oil in very fine droplets dispersed in the aqueous phase, easily diluted with water to a desired concentration order of application, the stability of emulsion can minimize droplet tapering and emulsifier stable effect to.
Silicone oil in the textile and apparel industry can be used as a fabric softening agent, lubricant, waterproofing agent, finishing agent and so on. In order to meet the demand for high-end textile products, chemical products manufacturers in the continuous development of energy and various functional additives such as waterproofing agent, flame retardant, antistatic agent, fixing agent the same bath using, feel good silicone oil. In addition, in order to improve the properties of fabrics and dyeing in one bath, and use of silicone products, have a cool sense of cotton with silicone oil, it can improve the fabric handle silicone products, it can impart the fabric good deep dyeing effect, good storage stability, it does not affect the color fastness, good hand feeling of the organosilicon intensifier deep agent. In addition to the textiles as an additive in textile functional, silicone products will also be applied to textiles in other areas, such as silicone and polyurethane composite forming fabric coating; silicone and polymerization of acrylic acid to form the fabric printing; organic silicon and organic fluorine combination surface of the forming fabric waterproof coating.
Silicone oil according to its process can be divided…
