Abstract
The invention relates to a manufacture method of a cable core. The manufacture cost of the cable core comprises the following steps: carbon fibers are led out of a creel, gum dipping is carried out to the carbon fibers after entering a first gum dipping area, and used epoxy resin is epoxy resin with heat-resisting high mechanical property; the carbon fibers after gum dipping enter a first curing oven to be precured, carbon fiber composite core are manufactured, the diameter of each carbon fiber composite core is 5mm to 12mm, and a curing degree reaches more than 85% by adjusting temperature; glass fibers on two sides are led out and respectively enter a second gum dipping area and a third gum dipping area, and used epoxy resin is high temperature resistant and weather resistant; the glass fibers after gum dipping pass through a winding area and are wound and cover the outer layers of the carbon fiber cores, the thickness of single side is 0.5mm to 2mm, and winding speed is synchronous with pultrusion speed by being controlled by a servo motor; and the carbon fiber composite cores and the glass fiber protective layers pass through the second curing oven after being compounded, and are fully cured by adjusting temperature. Composite material cable core products pass through a dragger and are wound up on the position of a winding disc.
Description
Technical field
The present invention relates to a kind of cable core, especially relate to a kind of manufacture method of cable core.
Background technology
Cable core is as the substitute products of traditional steel core, due to high temperature in the open air for a long time, and sunshine, work under the mal-conditions such as climate change, when requiring it to have good mechanical property, also have high temperature resistant, uvioresistant and ageing resistance etc., require very high to the combination property of cable core.
Traditional cable core structure is the load-bearing core that internal carbon fibers and epoxy resin composite material are made, and outside is the protective layer that glass fibre and epoxy resin composite are made, both shared same resin systems.Under the same resin system, interact between the performance such as high temperature resistant, tensile strength, bending strength, modulus, compression strength, uvioresistant and ageing resistance, by modification increase performance in a certain respect often to sacrifice on the other hand performance as cost.
Dicyclopentadiene (DCPD) is the dimer of cyclopentadiene, the by-product C 5 fraction and the carbonization of coal by-product light benzene fraction that mainly come from cracking of ethylene, because chemism is high, it is the raw material of Petropols and multiple fine chemicals, be introduced into epoxy resin, Properties of Epoxy Resin is improved, all be better than general purpose epoxy resin as its viscosity, mechanical property and good flame-retardance and toughness.
Summary of the invention
The present invention has designed a kind of manufacture method of cable core, and the technical problem of its solution is that the existing cable core exists the aspect of performances such as resistance to elevated temperatures, tensile strength, mechanical property, anti-flammability, compression strength, uvioresistant and ageing resistance poor.
