AI Technical Summary

Problems solved by technology

However, its components contain three components of zinc naphthalate, polyacrylic acid and chlorinated paraffin. The above three components have the functions of lubrication, surface treatment and enhancing the dispersion performance of flame retardants, but they are easily decomposed into halogenated gases, Naphthalene gas and other easily suffocating gases and strong carcinogens will cause great harm to the body and cannot meet people's requirements for safety

Embodiment 1

[0061] Embodiment 1: a kind of silicon core tube:

[0062] This embodiment provides a silicon core tube, which is specifically prepared through the following steps.

[0063] 1) Preparation of potassium diformate sustained-release microcapsules:

[0064] 1.1) The 5A zeolite molecular sieve was placed in a sufficient amount of 3% potassium diformate aqueous solution, stirred at 45°C and 450r / min for 4h, centrifuged, filtered to obtain the filter residue, and dried at 45°C for 12h to obtain the core material;

[0065] 1.2) Dissolve chitosan with a weight-average molecular weight of 120,000 and a degree of deacetylation of 92% in acetic acid solution of 2vol% to prepare a chitosan solution with a mass fraction of 1.0%, and then prepare the core material in step 1.1) according to a material-to-liquid ratio of 1:120 Add to the chitosan solution, stir at 50°C and 450r / min until uniformly mixed to obtain a mixed solution;

[0066] 1.3) Step 1.2) The mixed solution is slowly added dr...

Embodiment 2

[0080] Embodiment 2: Another silicon core tube:

[0081] This embodiment provides another silicon core tube, its components, formula, and preparation method are basically the same as in Example 1, the only difference is that in this embodiment, when preparing potassium diformate sustained-release microcapsules, the weight average Sodium alginate with a molecular weight of 120,000 was used instead of chitosan.

Abstract

The invention relates to the technical field of silicon core pipes, particularly to a corrosion-resistant flame-retardant silicon core pipe, which comprises an outer layer and an inner layer, whereinthe outer layer further contains nano SiO2 and potassium diformate slow-release microcapsules besides a traditional resin matrix, the inner layer contains polyurea material coated graphene and ammonium polyphosphate besides a traditional silicon core master batch and the resin matrix, and the corrosion-resistant flame-retardant silicon core pipe does not contain zinc naphthenate, polyacrylic acidor chlorinated paraffin. The corrosion-resistant flame-retardant silicon core pipe disclosed by the invention has an excellent inhibition effect on common microorganisms in soil, and prevents pipes from from being eroded and degraded by microorganisms, wherein the inhibition effect can be continuously provided; and the silicon core pipe is excellent in smoothness, the friction coefficient of the inner wall of the silicon core pipe can be as low as 0.1 or below, and the silicon core pipe further has good flame-retardant performance, does not escape toxic gas even if combustion occurs and is environmentally friendly.

Description

【Technical field】 [0001] The invention relates to the technical field of silicon core tubes, in particular to a corrosion-resistant and flame-retardant silicon core tube and a preparation method thereof. 【Background technique】 [0002] Due to the long laying distance of long-distance optical cables, there are many influencing factors. All parties try to improve the laying method and improve the stability of transmission performance. In the early stage of application, overhead or direct burial are generally used. Overhead is susceptible to external influences, and the transmission stability and drift are poor. It is difficult to locally relocate, increase capacity and divert roads for direct burial. Therefore, with the advancement of science and technology, pipeline protection has become the main laying method. The use of pipeline protection in optical cable engineering is a long-term and economical way. Pre-buried the pipeline, and then laid the optical cable in the pipel...
