Abstract

The invention discloses special nonflammable atomization silicon oil for spinneret plates of chemical fiber factories and a preparation method of the special nonflammable atomization silicon oil. The special nonflammable atomization silicon oil is made of, by weight, 2%-8% of polysiloxane resin, 90%-97% of phenyl silicon oil, 0.1%-2% of antioxidants, 0.1%-0.4% of dispersant and 0.1%-1% of preservatives. By adoption of the polysiloxane resin, excellent film forming performance and adsorbability are achieved, a uniform film can be formed in each mesh of the spinneret plates. In addition, the phenyl silicon oil has excellent irradiation resistance performance, high oxidation stability, high heat resistance, high flame resistance, high ultraviolet resistance and high chemical resistance. By addition of the antioxidants including alkylated diphenylamine and 2, 6-butylated hydroxytoluene, high temperature performance is further improved, operation temperature requirements of the spinneret plates can be met completely, and service lives of products are long. Effects of current products on the market last for two hours by once spraying while effects of the special nonflammable atomization silicon oil last for six hours by once spraying, and accordingly replacement and spraying frequencies are reduced, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technology in the field of silicone oil, in particular to a non-flammable atomized silicone oil specially used for spinnerets in chemical fiber factories and a preparation method thereof. Background technique [0002] The preparation of chemical fibers is usually made of natural or synthetic polymers or inorganic substances into a spinning melt or solution, then filtered, metered, extruded from a spinneret (plate) into a liquid stream, and then Solidified into fibers. The holes of the spinneret are usually sprayed with atomized silicone oil, so that the fibers formed by the spinning solution or melt from these microholes through final solidification or cooling are not easy to break. At present, the atomized silicone oils used in the market are filled with medium-viscosity dimethyl silicone oil or aralkyl silicone oil and propellant petroleum gas or dimethyl ether. The cost of this atomized silicone oil is low, but the pro...
