Background technique
There is production fabric the manufacturing method of thermally conductive function mainly to seep charcoal method, metal or non-with fiber surface at present
Metallic conduction particle coating technology, metal and nonmetal fiber blend method, chemistry, electrochemical process, spatter film forming method etc. produce thermally conductive fibre
Tie up fabric.It is applied on the product that the soft folding of height uses, that is, is showed not by the conductive fibers that the above method is made
Electroconductive electric heating fiber fabric made of the above method is applied to be addressed further under and is enumerating two kinds of typical height by same technological deficiency
It spends in the soft dairy products rolled over and used and is illustrated.(1) electric heating clothes；(2) electric heating seating washer, PDL table in practical applications
It is existing are as follows: (1)；Conductive particle easily falls off from fabric surface；(poor adhesive force) (2)；Anti- rubbing property is poor: (as different rubbings are rolled over,
Resistivity increases with permanent, finally loses thermally conductive function) (3)；Anti acid alkali performance is poor: (meeting strong acid and strong base and destroys thermal conductivity
Can) (4)；Long Term Contact atmosphere is oxidizable；(durability is poor, and resistivity extends at any time and sorrow subtracts) (5)；Washing fastness is poor.With
Upper defect limits the products application of the above-mentioned type of skill.
Most widely used thermo electric material the feel of product and is relaxed through PVC, PE clad alloy heating wire and carbon fiber at present
Adaptive is poor, and thermal sensation is also poor, and because thermo electric material is linear, heat is concentrated on one wire, so warming is scorching, it is to bear height
Temperature, safety coefficient are low.
As those skilled in the art again, it would be highly desirable to develop a kind of novel thermally conductive ribbon of flexible insulation, while there is fiber
The good heat conductive material of fabric softness.
Summary of the invention
The purpose of the present invention is being directed to existing problem, a kind of thermally conductive ribbon of flexible insulation is provided.
The invention is realized by the following technical scheme:
A kind of thermally conductive ribbon of flexible insulation, is made by following parts by weight of component: 70 ~ 95 parts of polyphenylene sulfide, soluble polytetrafluoroethyl-ne

Further, the barium titanate whisker uses calgon in dehydrated alcohol by roasting in a vacuum furnace after cooling
In be dispersed with stirring, then atmospheric plasma is handled, then the ultrasonic wave dispersion, clear in the deionized water containing calcium stearate dispersion
It washes, suspension whisker in solution upper layer is taken to be filtered, take modified crystal whiskers mixed liquor, and repetitive operation is until filtering, in vacuum after filtering
Baking oven dries to arrive modified barium titanate whisker.
Further, the boron nitride nanosheet is to carry out coupling modifier to boron nitride nanosheet using silane coupling agent to obtain
It arrives.
Further, the anti-aging agent is that quinoline type antioxidant, p phenylenediamine type antioxidant and mercaptobenzimidazole class are anti-
One of old agent is a variety of.
Further, above-mentioned each group being placed in high-speed mixer, blending while, must heat 320 ~ 350 DEG C, to
Being completely dried rear can be taken off, and be granulated cold cut using double screw extruder, then pass through double screw extruder melting extrusion and pass through
Manifold spinneret spinneret, cooling, sizing obtains twine；By twine knitmesh to get arrive the thermally conductive ribbon of flexible insulation.

The thermally conductive ribbon of flexible insulation disclosed by the invention, by producing the function with thermal conduction characteristic to fabric blending and modifying
It can property material.Heating conduction depend on polar functionalities number and polar group dipole moment degree of polarization.General polarity height is poly-
Object has this variation, and polar group contained by polyphenylene sulfide, soluble poly tetrafluoroethene is more, and is easier to polarize, so it
Thermal conductivity is higher.Thermal conductivity additionally depends on intramolecular tightness degree, and C-F key is tightly combined, and c h bond combines pine to dredge, so
The thermal conductivity of polytetrafluoroethylene (PTFE) is bigger than polyethylene.Many high molecular materials are made of asymmetric polarity chain link, such as polychlorostyrene
Ethylene, polypropylene, polyester etc., they belong to crystalline state or amorphous material, entire strand cannot complete free movement, only
The vibration of atom, group or chain link can occur, therefore, heating conduction is very poor.
The thermally conductive ribbon of flexible insulation disclosed by the invention further increases thermal conductivity using inorganic conductive particle.It is main logical
The structure and performance of toning conduct hot particle, dosage, surface be modified and preparation process improves thermal conductivity.Similar conductive particle
Structure, physical and chemical properties often have very big difference, the performances of different particles for the thermal conductivity of ribbon, price, shape,
Stability is most important.Simultaneously under the premise of improving thermal conductivity, guarantee mechanics and other physical properties.
The present invention has the advantage that compared with prior art
The thermally conductive ribbon of flexible insulation disclosed by the invention, resisting soft folding endurance is that other any thermo electric materials can not be than as, surely
Qualitative excellent, heat-proof combustion-resistant is ageing-resistant, and thermal coefficient is high, securely and reliably, can be used as basic Heat Conduction Material for producing various electricity
Hot far infrared.According to the concrete function and characteristic of the thermally conductive ribbon of flexible insulation, following field can be respectively applied to:
Warming article: the industrial and minerals such as electric heating clothes, vest, gloves, electrothermal diving dress appliances for labor protection and army's articles: electrothermal foot-warming
Bag, shoes and hats, bedding and clothing, pillow, sofa etc.；Automobile-used equipment: automobile-used antifreeze seat (pad), mattress, steering wheel gloves etc..
The thermally conductive ribbon aspects above of flexible insulation disclosed by the invention all has unique advantage, will replace traditional electric heating
Material.Especially in high-end electric heating products market, there is excellent performance, while rubbing folding endurance and stabilization but also with the highly resistance of fabric
Property, to require high field to have other thermo electric material institute nothings in product flexibilities degree such as electric heating clothes, electric heating (piece) seat cushions
The advantage of method analogy, the thermally conductive ribbon of flexible insulation are that direction is widened in the development of thermo electric material in future.
