Problems solved by technology

[0005] However, winding reels made of various plastics such as ABS, PP, PC (polycarbonate) or glass fiber reinforcement have the following problems: (1) Poor drop resistance, easy to be damaged when encountering rough loading and unloading, affecting recycling; (2) The protection of the cable is poor, and the transmission performance of the optical cable is greatly reduced due to the impact of stress in the case of brutal loading and unloading, and sometimes it is even scrapped and cannot be used

Embodiment Construction

[0030] The raw material of the modified optical cable winding reel of the present invention is constituted by mass percentage:

[0031]

[0032] The preparation method is as follows:

[0033] 1. Preparation of modified nano silicon nitride whiskers:

[0034] Put 100g of nano silicon nitride whiskers into 300g of nitric acid solution with a mass concentration of 60%, react at 100°C for 36 hours, wash with distilled water to neutrality after the reaction, and dry at 100°C to obtain carboxylated nano silicon nitride ; 400g of thionyl chloride and the obtained carboxylated nano silicon nitride reacted at 80 ℃ for 36 hours, after the reaction is completed, washed with anhydrous tetrahydrofuran to neutral, 100 ℃ vacuum drying to obtain acyl chloride nano silicon nitride; The acyl chloride nano silicon nitride is mixed with octadecylamine and benzene in a mass ratio of 1:10:10, reacted at 60°C for 36 hours, washed with anhydrous tetrahydrofuran to neutrality after the reaction, and dried i...

Abstract

The invention discloses a modified optical cable wire reel and a preparation method thereof. For the modified optical cable wire reel, a nano-silicon nitride whisker is employed to perform technical treatment on ordinary engineering plastic nylon 6 by a nanotechnology, and the modified nylon 6 has the characteristics of reinforced strength, increased toughness, and resistance to aging for 10 years. The wire reel formed by injection moulding of the modified nylon 6 engineering plastic can load 500kg of optical cables, and after drop from a height of 1.6m, the wire reel does not crack and deform, its various properties do not change in a temperature ranging from -40DEG C to 70DEG C, and can be reused more than 10 times.

Description

1. Technical Field [0001] The invention relates to an optical cable winding reel for communication optical cable and feeder transportation, in particular to a modified optical cable winding reel and a preparation method thereof. 2. Background technology [0002] At present, the various optical cable winding reels on the market are made of wood without exception. The advantages of wooden winding reels are good cushioning and low price. Even if the operators are rough handling, they can better protect the optical cable. The transmission performance of the line, so the wooden winding reel has been favored for a long time. [0003] In recent years, the rapid development of my country's communications industry requires the use of a large number of disposable wooden reels each year, resulting in a large number of adult green forests being felled. With green environmental protection, the concept of low-carbon and energy-saving has become a national policy. The era when a large amount of ...
