Description
Technical field
The present invention relates to canvas field more particularly to a kind of preparation methods of insulating heat-conductive canvas.
Background technique
Canvas is the cotton fabric or linen of a kind of thicker thickness, is gained the name because being used primarily for sail.Generally mostly use plain weave
Tissue, a small amount of use twill-weave, warp and weft use multi cord.Canvas usually divides canvas and fine canvas two major classes.Canvas
Also known as shelter cloth, has a good waterproof performance, maximum feature be exactly it is durable, for Automobile Transportation and open storage
It covers and field is pitched a tent.Fine canvas is for making labour protection clothes and its articles, after dyeing or stamp, it is also possible to make
Footwear material, bag fabric, handbag, knapsack, tablecloth, tablecloth etc..Although canvas using relatively broad, what it was serviced at present
It is most of all in low side field.It is generally known that China is an electricity consumption big country, all trades and professions also all be unable to do without electricity.But due to every
Fire caused by year electrical wiring aging, electric leakage is quite a few.Present cable, electric wire all use rubber plastic to be wrapped up, but
The hair for phenomena such as being plastic products in the environment of outdoor long-term exposing to the weather, winter alternates with summer, aging, cracking can inevitably occur
It is raw.It is in terms of battery and the same not only in terms of electric wire, after the battery long-time charge and discharge used now, inside battery
How much have part electric energy and be converted into thermal energy, if thermal energy cannot be released from inside battery in time, it is easy to cause battery
Explosion.And canvas material has preferable ventilation heat dissipation performance, for this purpose, the invention discloses a kind of systems of insulating heat-conductive canvas
Preparation Method can protect well conductor, while also can by the way that insulating heat-conductive canvas to be wrapped in the outside of conductor
Enough heats for generating fax during pass in time, avoid the generation of electricity consumption disaster.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of preparation method of insulating heat-conductive canvas,
Not high to solve protective cover of conductor service life in the prior art, affected by environment larger and conductor is in electric transmittance process
The interior of middle generation can be easy accumulation, the technical problems such as cannot discharge in time；
In order to solve the above technical problems, the invention discloses a kind of preparation methods of insulating heat-conductive canvas, including following system
Standby step:

Solarization, acid rain resistant, while not also being afraid of upper mould and damaging by worms, while also use intensity with higher.
Step 2: the preparation of adhesive layer
Polyamide hot and phenolic resin are matched according to 3~5:1 of mass ratio, is put into beaker heat and melt
Melt stirring, adhesive is made after mixing, it is spare；
Step 3: the preparation of insulating layer
By Isosorbide-5-Nitrae-two (4- amino -2- 4-trifluoromethylphenopendant) biphenyl, 4,4- bis- (hexafluoro isopropyl alkene) two anhydride phthalic acids and 2,
3,3,4- bibenzene tetracarboxylic dianhydrides pour into reaction kettle according to mass ratio 6:3:3, and dimethylacetamide is added into reaction kettle
Amine solvent carries out heating stirring, and after removing solvent, Kapton insulating layer material is made；
Step 4: bonding
Compression bonding, glue will be carried out by adhesive between Kapton insulating layer material obtained and base band canvas
After glutinous agent is cooling, insulating heat-conductive canvas is made.Polyimides is the aromatic heterocycle polymer that molecular structure contains imide chain link
Compound contains greatly and in strand the conjugation of a large amount of heteroaromatic due to its main chain bond energy, causes polyamides sub-
Amine molecule is nontoxic, and have excellent electrical insulating property, mechanical property, high temperature resistant, radiation hardness, resistant to chemical etching, waterproof and
The performances such as self-extinguishing without fire.
Preferably, the surfaces externally and internally of base band canvas is also coated with waterproof coating, and waterproof coating is that packet is immersed in by base fabric
It is formed after dipping glue containing PTFE emulsion and after drying.
Preferably, in order to improve the interior high-temperature behavior of canvas, further include silica white or flake asbestos in adhesive, prevent summer
Temperature is excessively high to generate superheating phenomenon to canvas inside.
Preferably, compression bonding is carried out to insulating heat-conductive canvas using clamping plate in step 4, pressure control 100~
The time of 200N, compression are not less than 30 minutes.
The invention discloses a kind of preparation method of insulating heat-conductive canvas, the present invention has process simple, polyester sail
The intensity and heat radiation gas permeability of cloth itself can make polyester canvas, and itself is a excellent heat carriers, and will gather
Ester canvas and Kapton carry out it is compound so that the Kapton face in insulating heat-conductive canvas is one excellent exhausted
Edge body can be good at protecting conductor, prevent electric leakage, short circuit phenomenon from occurring, while polyester canvas also has preferably using strong
Degree prevents conductor from being occurred to stretch by external force, be deformed.
