Anti-interference waterproof weather-proof data cable material and preparation method thereof

Abstract

The invention discloses an anti-interference waterproof weather-proof data cable material which comprises the following raw materials in parts by weight: 60-70 parts of low molecular weight polyvinylidene fluoride, 40-50 parts of PVB resin, 10-14 parts of polyethylene wax, 6-10 parts of polyvinyl alcohol, 4-8 parts of coupling reagent, 7-9 parts of a rare earth zinc calcium compound stabilizer, 8-10 parts of a water-resisting additive, 3-7 parts of a lubricating agent, 10-20 parts of an electromagnetic shielding additive, 12-16 parts of a processing agent and 7-9 parts of carbon black. The cable material disclosed by the invention has better surface flexibility, smooth touch feel, acid-base resistance property, anti-aging property, excellent signal shielding effect, high temperature resistance and high mechanical strength; besides, the data cable material has a better waterproof property; and meanwhile, the material cost is low, the raw materials are easily available, the preparation method is simple and the data cable material has high practical value and excellent application prospect.

Description

technical field [0001] The invention relates to the technical field of electronic product accessories, in particular to an anti-interference waterproof and weather-resistant data cable material and a preparation method thereof. Background technique [0002] On the one hand, the low-smoke and halogen-free flame retardant systems of domestic cable sheaths are mainly concentrated in two directions: one is organic phosphorus and nitrogen; the other is inorganic hydrates. There are many kinds of organophosphorus nitrogen flame retardants, and the main flame retardant mechanism is to use the covering effect after carbonization. The disadvantage is that the molecular weight is small, and it is easy to drip after being charcoal. The flame retardant of inorganic hydrate mainly depends on the loss of water and heat absorption of inorganic hydrate at high temperature. The commonly used flame retardants are aluminum hydroxide, magnesium hydroxide, zinc borate, etc. The low-smoke and h...

Problems solved by technology

[0004] In addition, the thermoplastic elastomers currently commonly used in the production of earphone cables and data cables generally contain mineral oils such as paraffin oil or naphthenic oil, which are likely to cause yellowing of the wire during product use, and the surface is sticky, dust-absorbed, precipitated, and not resistant to dirt , there is no dry feel, and it cannot meet the increasingly stringent requirements of consumers

For signal transmission cables with high signal transmission requirements, the anti-interference ability is poor during the transmission process, and the signal distortion is high, so it cannot meet people's needs.
