Description
Technical field
The present invention relates to rubber materials, more particularly to a kind of rubber surface Teflon handling process.
Background technology
Rubber industry is one of important foundation industry of national economy.Although rubber is applied extensively, but with
Industrial expansion, the original characteristic of rubber can not meet the needs of reality.To obtain the rubber of higher performance, generally
Be on the basis of rubber primary characteristic, improvement improvement carried out to rubber surface with reference to some special handling process, to up to
To higher expection.
Teflon material has the excellent performances such as non-stick, sliding, moisture resistance, wear resistance, corrosion resistance in itself,
This material also be used to be grafted onto on rubber, and this method is exactly to spray teflon material in rubber surface.Due to rubber
The characteristic of glue in itself, its temperature range that can bear limits, and the nonconducting characteristic of rubber, in addition Teflon under low temperature environment
It is difficult to be attached to rubber surface so that the technique that rubber surface carries out Teflon processing is difficult to.Existing Teflon handles skill
Art, it is only applicable to the material that base material melting temperature is far higher by Teflon melting temperature.For the material of rubber like class, due to it
Under the conditions of Teflon melting temperature, easily aging denaturation it may burn, there is presently no the Teflon of effective rubber surface
Dragon processing applicable technology.Also can only be to smear slip agents, or the mode such as powder in rubber surface even if there is the demand of this respect
Substitute, these methods can only maintain shorter a period of time, can not realize long-term lasting effect.Also have in addition it is a kind of using etc. from
The method of daughter spraying, sprays to Teflon on rubber surface although can realize, plasma spraying needs high-end
Equipment, complicated operating procedure and various strict condition controls, cause cost very high.
From the above, it is seen that conventional spray paint method is difficult to the Teflon processing of rubber surface, even if can also face
Face the problem of using high special equipment, complex operation, high cost, in addition the coating after the Teflon processing of rubber surface
Firmness is also difficult to ensure that these problems mustn't go to effective solution, and the Teflon processing of rubber surface is just difficult to, also with regard to pole
The big extensive use for limiting Teflon processing rubber.
The content of the invention
It is an object of the invention to provide one kind is simple to operate, cost is relatively low and can effectively realize at rubber surface Teflon
The technique of reason.
To reach above-mentioned purpose, the technical solution adopted in the present invention is：A kind of rubber surface Teflon handling process, bag
Include following steps：
Step 1, the impurity of rubber surface is cleaned using alcohols solvent, then by rubber air drying, is vapored away molten
Agent.
Using supersonic wave cleaning machine, rubber is placed in alcohols solvent, it is common such as isopropanol, toluene, butanone, first
One kind in alcohol or appoint is cleaned in several solvents, to remove the impurity of rubber surface adhesion, such as releasing agent, medicine precipitate, clearly
After wash clean, rubber is taken out and filters net liquid body, then put into drying box and spontaneously dry, evaporation of solvent.These early stages
Cleaning work, the solidification for being advantageous to Teflon solution in rubber surface adhere to
Step 2, the Teflon original solution of diluting high-concentration, according to every 100ml organic solvents 4~10g Teflon original solutions
Standard be diluted, the Teflon solution of spraying is made.
The Teflon original solution of described high concentration, solute are the teflon particle that size is less than 100 nanometers, and solvent is ketone
Class organic solvent, so-called high concentration, refer to be in supersaturated state during solution normal temperature, the solution appearance formed is into the cream color, sticky
Shape, volatility is relatively low, and typically operation is diluted using magnetic stirrer to prevent from polluting and volatilizing.
Step 3, the Teflon solution diluted is injected into flush coater, to rubber surface even application.By what is stirred
Teflon solution is injected into flush coater, sets spraying rate and spray time, and flush coater is automatically performed to rubber
Spraying.
Step 4, by the rubber after spraying, it is put into drying box and spontaneously dries, vapor away organic solvent.
Step 5, by the rubber after spraying, it is put into insulating box, temperature control is at 90 DEG C~110 DEG C, time control
In 10min~10.5min, it may advantageously facilitate Teflon nano particle and be attached on rubber, and be denatured rubber, reach
Rubber is taken out after setting time, that is, completes the solidification of teflon coatings.
Alcohols solvent in described step 1 is isopropanol, toluene, butanone, one kind in methanol or appointed several.These are all
It is the conventional solvent of industry, it is relatively low obtains easy cost.
Nano particle in described nanoscale Teflon original solution is less than 100 nanometers.Described nanoscale Teflon is former
Solution is the supersaturated solution of nano particle.Particle less than 100 nanometers is liable to stick to rubber surface, it is not easy to comes off, mistake
Teflon nano particle has higher concentration in saturated solution, and Teflon nano particle amount is relatively more.
Organic solvent in described step 2 is isopropanol, toluene, butanone, one kind in methanol or appointed several.These are all
It is the conventional solvent of industry, it is relatively low obtains easy cost.
Described step 1 cleaning operation uses supersonic wave cleaning machine.Stirring operation uses magnetic agitation in described step 2
Machine.The plant equipment commonly used in these industrial productions, easily obtain, and using effect is preferable.
In practical application, rubber surface passes through the spraying of a Teflon solution, and the coating of rubber surface may not reach
Required thickness, the operation of step 3~step 5 at this moment rubber can be repeated several times, to meet thickness requirement.
The present invention has innovated a kind of rubber surface Teflon handling process, and the technique has that simple to operate, cost is relatively low, effect
The characteristics of fruit is good, the problems such as difficult, insecure, the difficult control of thickness of Teflon attachment are efficiently solved, rubber is improved and uses
Ability and performance, widen the application of rubber.
