Description
Technical field
The present invention relates to electric wire, more particularly to a kind of fire resistant polyvinyl chloride jacketed cable.
Background technology
Electric wire is for transmitting electric energy, information and realize the wire product of electromagnetic energy conversion, including conductor and to be arranged
The sheath of insulation on conductor, sheath is enclosed on conductor, and conductor is played a protective role, and this requires sheath has excellent
Various electrical insulation capabilities, when meeting with fire, sheath is also needed to excellent fire-retardant, ageing-resistant performance, resistance to elevated temperatures.
Authorization Notice No. is CN205751670U Chinese patent《A kind of cross-linked polrvinyl chloride insulation PVC sheath electricity
Power cable》Disclose a kind of cable, including insulation PVC sheath, copper conductor and two test leads being arranged side by side.
Above-mentioned cable directly uses insulation PVC sheath, and heat and high ambient temperature during cable use make insulation polychlorostyrene second
Alkene sheath is chronically at a high temperature of heat effect, and heat ageing phenomenon easily occurs for insulation PVC sheath, causes insulating properties
Reduction and deformation, influence Electrical Safety, form electricity consumption hidden danger.
The content of the invention
It is an object of the invention to provide a kind of fire resistant polyvinyl chloride jacketed cable, with resistant to elevated temperatures effect.
The present invention above-mentioned technical purpose technical scheme is that：A kind of fire resistant polyvinyl chloride sheath
Cable, including conductor and sheath, by weight, the sheath include 60-80 parts of polyvinyl chloride；20-30 parts of epoxy resin；It is hollow
10-20 parts of polyurethane nanofiber.
By using above-mentioned technical proposal, polyvinyl chloride is a kind of one replaced using a chlorine atom in polyvinyl chloride
The high polymer material of hydrogen atom, is the amorphous polymer containing a small amount of crystalline texture.Epoxy resin is added in polyvinyl chloride,
Epoxy resin is to refer to the organic compound containing two or more epoxide groups in molecule, in addition to indivedual, their phase
It is not high to molecular mass.Epoxy resin and polyvinyl chloride are macromolecule, and polyvinyl chloride molecule and epoxy molecule can be
Wound in three dimensions, inevitably formation is tangled in three dimensions, these, which tangle, to limit big as chemical crosslinking
The movement of molecule segment.
Hollow polyurethane nanofiber is additionally added in sheath, polyvinyl chloride molecule and epoxy molecule can be partially filled with
In hollow polyurethane nanofiber.When meeting with fire or being worked for a long time in hot environment, sheath is heated by becoming for deforming
Gesture, sheath deformation firstly the need of the entanglement overcome between polyvinyl chloride and epoxy molecule, next need polyvinyl chloride and
Epoxy resin departs from out of hollow polyurethane nanofiber, and then lifts the thermal denaturation temperature of sheath so that sheath is at high temperature
It is unlikely to deform, lifts the heat resistance of sheath, fire resistant polyvinyl chloride jacketed cable has excellent high-temperature resistant result.
In addition, epoxy resin and polyvinyl chloride are entered in hollow polyurethane nanofiber, hollow polyurethane nanofiber
With good barrier properties for gases, reduce oxygen and enter in sheath.Secondly as during epoxy resin and polyvinyl chloride are entered
In empty polyurethane nanofiber, hollow polyurethane nanofiber can rise to the motion of epoxy resin and the macromolecular chain of polyvinyl chloride
To inhibition, make sheath that there is higher decomposition temperature, and original shape can be also kept in burning, be difficult at high temperature
Deformation, so that sheath has excellent fire resistance.
The further setting of the present invention is：Also include 5-15 parts of nano-powders in the sheath.
By using above-mentioned technical proposal, nano molecular is also nano particle, refers generally to size super between 1-100nm
Fine particle.Nano-powder has larger specific surface area, with good adsorptivity, after being added in sheath, part nano powder
Know from experience the multiple material touched simultaneously in hollow polyurethane nanofiber, epoxy resin, polyvinyl chloride, improve the structure of sheath
Intensity closes thermal denaturation temperature, further improves the heat resistance of sheath.
The further setting of the present invention is：Also include 2-5 parts of dispersants in the sheath, the dispersant is polyvinyl chloride
One kind in butyral, polyvinyl chloride alcohol.
By using above-mentioned technical proposal, the reunion of nano-powder refers to that nano-powder particle is connected with each other, has multiple
Phenomenon of the particle shape into larger particles cluster.By adding dispersant agent in sheath so that nano-powder is distributed in sheath
It is even, reduce Cluster Phenomenon..
The further setting of the present invention is：Also include 2-8 parts of nanometer Sb in the sheath2O3。
By using above-mentioned technical proposal, nanometer Sb2O3It is added in sheath, with excellent fire resistance.
The further setting of the present invention is：The sheath preparation method is as follows, weighs polyvinyl chloride, the asphalt mixtures modified by epoxy resin of parts by weight
After fat melting mixing, hollow polyurethane nanofiber is added, extrusion molding after being well mixed.
By using above-mentioned technical proposal, formed and tangled after polyvinyl chloride and epoxy resin melting mixing, between macromolecular,
Add after hollow polyurethane nanofiber, polyvinyl chloride and epoxy resin can be entered inside hollow polyurethane fiber.
The further setting of the present invention is：The sheath preparation method is as follows, weighs polyvinyl chloride, the asphalt mixtures modified by epoxy resin of parts by weight
After fat melting mixing, add after hollow polyurethane nanofiber, nano-powder, dispersant, with ultrasonication, after being well mixed
Extrusion molding.
By using above-mentioned technical proposal, by ultrasonication, first, promote the scattered of nano-powder, second, pass through
The concussion effect of ultrasonic wave promotes epoxy resin and polyvinyl chloride to enter in hollow polyurethane nanofiber, the 3rd, ultrasonic wave
Can be well mixed epoxy resin, polyvinyl chloride, nanometer powder etc..
The further setting of the present invention is：Including 75 parts of polyvinyl chloride in the sheath, 25 parts of epoxy resin, 13 parts are hollow
Polyurethane nanofiber.
By using above-mentioned technical proposal, polyvinyl chloride selects 75 parts, is used as the main component of sheath.Epoxy resin is selected
25 parts, uniformly mixed with polyvinyl chloride.
In summary, the invention has the advantages that：First, using addition polyvinyl chloride and asphalt mixtures modified by epoxy resin in sheath
It is fine that fat and hollow polyurethane nanofiber, polyvinyl chloride molecule and epoxy molecule partly enter hollow polyurethane nano
In dimension, the thermal degradation temperature and heat resistance performance of sheath are improved.Second, sheath is interior to add nano-powder, promotes polyvinyl chloride, ring
Connection between oxygen tree fat, hollow polyurethane nanofiber, improves the heat resistance and fire resistance of sheath.
