Packing special for anticorrosive high-strength fiber sheath material and preparation method thereof

Abstract

The invention discloses a packing special for an anticorrosive high-strength fiber sheath material. The packing is prepared from the following raw materials in parts by weight: 6-9 parts of zinc borate, 15-18 parts of roasted zeolite powder, 4-6 parts of nano calcium carbonate powder, 2-3 parts of triethanolamine, 2-3 parts of sodium diacetate, 3-4 parts of tungsten trioxide, 2-4 parts of tantalum carbide, 2-4 parts of pentaerythritol phosphate, 1-1.5 parts of melamine polyphosphate, 40-45 parts of medical stone powder, a proper amount of water, a proper amount of 4-6% hydrochloric acid and 15-20 parts of aid. Tungsten trioxide, triethanolamine and sodium diacetate are used in the packing, so that the sheath material has antibacterial and anticorrosive performance; by using the roasted zeolite powder and the nano calcium carbonate powder, the sheath material has high thermal deformation temperature and dimensional stability, and the air tightness is improved; by using the medical stone powder, the cost is reduced; by using the aid, the dispersibility and reinforcing performance of the packing can be improved; the packing also has good flame-retardant performance and good durability.

Description

technical field [0001] The invention belongs to the field of optical fiber sheath materials, in particular to a special filler for anti-corrosion high-strength optical fiber sheath materials and a preparation method thereof. Background technique [0002] With the rapid development of the data communication industry, optical fiber is being widely used as the carrier of data transmission. The laying forms of optical fiber are buried and overhead, and with the transformation of urban network lines, most of them have been transferred underground. In order to prevent underground optical fibers and optical cables from being bitten or corroded by insects, sheath materials for optical fibers and optical cables have emerged as the times require. At present, polyethylene is mainly used as the sheath material for optical fibers and optical cables, which has the characteristics of light weight, high bending strength, small friction coefficient, good sealing performance, and corrosion r...

AI Technical Summary

Problems solved by technology

At present, polyethylene is mainly used as the sheath material for optical fibers and optical cables, which has the characteristics of light weight, high bending strength, small friction coefficient, good sealing performance, and corrosion resistance. However, this pipe still has many shortcomings, such as corrosion resistance in harsh environments. If the performance is not good enough, its performance needs to be improved, and its performance can be improved by adding fillers
