example 1

[0030]According to the mass ratio of 1:12, mix sepiolite and hydrochloric acid with a mass fraction of 20% and pour it into a beaker, and move the beaker into a digital speed measuring and constant temperature magnetic stirrer. Soak for 4 hours, then filter to obtain a filter cake, and wash the filter cake with deionized water for 5 times, then transfer the washed filter cake to an oven, and dry it to a constant weight at a temperature of 110°C to obtain a dry filter cake. Then transfer the obtained dry filter cake to a tube furnace, and then heat-preserve and roast for 3 hours at a temperature of 240°C, then cool to room temperature with the furnace, and discharge the material to obtain modified sepiolite, which is the gelling agent; by weight Counting, take 15 parts of polyacrylamide, 5 parts of emulsifier, 6 parts of crosslinking agent, 50 parts of water in turn, first mix polyacrylamide and water into the reaction kettle, stir and mix at 600r / min for 45min, and then Add em...

Abstract

The invention discloses an ointment special for filling of optical cables and belongs to the technical field of electronic information materials. The ointment special for filling of optical cables, developed by the invention, is prepared from base oil, a gelling agent, an antioxidant, isocyanate, a No.1 additive and a No.2 additive, wherein the No.1 additive is obtained by firstly stirring and mixing polyacrylamide and water, then sequentially adding an emulsifying agent and a cross-linking agent, performing stirring dispersion, performing thermal insulation standing and then performing high-speed stirring and mixing; the No.2 additive is obtained by mixing (N-guanyl) dodecyl acrylamide and polyethylene glycol phosphate, adding p-dichlorobenzene and ferrocene and performing constant-temperature stirring reaction; the base oil is prepared from dimethyl silicone oil, white oil and coalite tar; and the gelling agent is modified sepiolite. The prepared ointment special for filling of optical cables has excellent bubble stability, can effectively reduce the viscosity of a system, increases the air resistance of the inside of the system, and avoids external humidity and moisture from permeating into the optical cables so as to obviously enhance the oxidation resistance of the optical cables.

Description

technical field [0001] The invention discloses a special ointment for optical cable filling, which belongs to the technical field of electronic information materials. Background technique [0002] In the past ten years, with the rapid development of communication technology, the application fields of optical cables have been expanding day by day, the environmental requirements have also been continuously improved, and the quality requirements and scope of application of cable materials have also increased. Optical cable filling paste is a water-blocking material commonly used in the optical cable industry. It is filled in the gaps of different parts of the optical cable. It has been recognized by people for its sealing, waterproof, moisture-proof and buffering protection functions in the optical cable. It has been improved and perfected with the development of optical cables. [0003] As we all know, hydrogenated base oil is the most effective means to improve the quality o...
