Abstract

Provided is an optical cable insulation fireproofing coating spraying process which is characterized in that a boron carbon source solution carried by nitrogen is sprayed onto the incoming fiber, the flow of the nitrogen is 100 sccm, and the flow of the boron carbon source solution is 2.0ML / min, the flow is controlled by a mass flow meter to obtain a BCN fireproofing insulation film on an optical cable, the thickness of the film is in the range of 180-220nm. The purity of the reaction source of the boron carbon source solution is 99.99%, the boron carbon source solution is carried by the nitrogen to lead to the optical cable. The purity of the nitrogen reaction source is 99.99%. The process is advantageous in that the optical cable insulation fireproofing coating spraying process can realize the film to have the advantageous performances of acid and alkali resistance, corrosion resistance, and insulation and fireproofing, the BCN film thickness is small, the weight of a conventional optical cable protective sleeve is greatly reduced, so that the optical cable protective sleeve can be convenient to carry and has the effect of an optical cable protective layer.

Description

technical field [0001] The invention relates to the application research field of optical cable insulation fireproof coating, in particular to a spraying process of optical cable insulation fireproof coating. Background technique [0002] Although the traditional PVC sheath has flame retardancy, its moisture resistance is poor and it is not suitable for outdoor use. According to reports, foreign countries have developed both indoor and outdoor introduction optical cables or down-rod optical cables, which can withstand outdoor low temperature and ultraviolet radiation, and can be flame-retardant and easy to bend and route. This optical cable adopts PVC tight-buffered optical fiber, water-absorbing powder dry-type water-blocking and low-smoke, halogen-free, flame-retardant sheath. Domestic research is still in a backward state. Moreover, once an open flame is encountered, the traditional optical cable is difficult to effectively control the fire due to its unsatisfactory fla...
