Description
Technical field
The present invention relates to technical field of mold release, more particularly, to polyether-ether-ketone film technical field of mold release, especially
Refer to a kind of 5 microns of the thickness that high-efficiency environment friendly economy is non-ignitable ultra-thin polyether-ether-ketone film parting agent specials.
Background technique
When manufacturing macromolecule material product, molded method is generally used, melt or molten liquid material are injected into mold,
After curing molding, then it is removed from the molds.It, generally can be on mold in advance using demoulding in order to help to be removed from the molds product
Agent.
Release agent is a kind of functional materials between mold and manufactured goods, be prevent rubber, plastics, elastomer or
Mechanograph, laminated product of other materials etc. are bonded on die surface, play the role of a kind of processing aid for being easy to be detached from.
The usually used release agent of engineering plastics processing film has three kinds of release agents such as petroleum (wax) system, silicon systems and fluorine system:
Petroleum (wax) be it is cheap, adhesion property is preferable, the disadvantage is that being easy pollution mold and manufactured goods；Silicon systems are moderate, isolation
Better performances are small to mold and manufactured goods pollution；Fluorine system is expensive, and isolation performance is very good, almost to mold and manufactured goods
It does not pollute.Wherein fluorine system than silicon systems almost few an order of magnitude in dosage, head works as when for the processing of precise electronic component
It rushes the preferably not siliceous fluorine system releasing agent in ground.
Fluorine-containing demoulding agent is a kind of fluoride-containing PMMA, is high efficient demoulding agent of new generation.With traditional wax class and silicone oil
Class release agent is compared, and fluorine-containing demoulding agent is with low using concentration, effect on environment is small, spraying is once used multiple times, can improve
Production efficiency has good stripping result to high cohesiveness product, and product surface residual is few without polluting product and mold, not shadow
Product secondary operation (such as spray painting is printed, bonding) excellent characteristics is rung, is received by the market.
PEEK (polyetheretherketone, polyether-ether-ketone) is (former empire of Britain Wei Gesi (Victrex) company
Learn ICI) last century the seventies exploitation a kind of special engineering plastics haveing excellent performance, belong to the crystallization that fusing point is up to 345 DEG C
Property polymer.There are many significant advantages compared with other special engineering plastics, high temperature resistant, mechanical performance be excellent, self-lubrication
It is good, chemicals-resistant burn into is fire-retardant, peel resistance, radioresistance, insulating properties are stable, hydrolysis and easy processing etc., navigate in aviation
It, automobile manufacture, the fields such as electric, medical and food processing are used widely.It is released from summer Wei Gesi in 2007
In the world after first PEEK film line, PEEK film maximum breadth 1.5m, has been used for insulated electro by 3~750 μm of thickness
Line/cable, semiconductor, automobile and aircraft industry can do microphone vibrating diaphragm and pressure-sensitive adhesive band bottom.
But Henkel KGaA Frekote 55-Nc semi-permanent mould release agent is used to process 5 microns of ultra-thin polyether-ether-ketones of thickness
When membrane product, encountering repeatedly needs the problem of rearranging fold after product is removed from the molds, and release agent moves to product
Surface needs secondary cleaning, otherwise can not be with troublesome a series of problems, such as fine copper voice coil bonding endlessly, and the product makes
Release agent is diluted with conventional inflammable and explosive solvent, it is upper heavily regulated in transport.

And surface treating agent) describe, three of the above solvent is used in mixed way constantly with HFE class or PFC class fluorocarbon solvent, noninflammability accounting
Between 3.75-10wt%, so embodiment and comparative example can be assessed with flash-point test.
Flash-point is tested in two steps, and sequence arrangement from low to high, flash-point uses the silent agar diffusion method of Bin Siji-Martin lower than 79 DEG C
(GB/T261-2008 standard), 79 DEG C or less can not measure flash-point and then use Cleveland opening agar diffusion method (GB/T3536-2008 mark
It is quasi-).
2, demolding performace is tested
To evaluate detachability, mold release compositions of the invention are sprayed to (5 centimetres of size (width) * 7 centimetres of latten(-tin)
* 0.3 centimetre of (length) (thickness)), precoating part sample then is made after sufficiently dry solvent.This is not sprayed by another with all-purpose adhesive
The latten(-tin) of the mold release compositions of invention is mutually bonded with the precoating part sample, if the shearing peeling force of adhesive layer is less than
The composition of 100 every square metre of gram forces is indicated with √, otherwise is greater than composition use × expression of 100 every square metre of gram forces.
3, life test is demoulded
Sticking to mould can need shaping again to evaluate with fold occurs when film manufactured goods depanning.Mold release compositions are sprayed
After being coated onto test die head, behind the number of pressing mold will count on sticking to mould next time.Pressing mold number can be used for evaluating holding for release agent
Long property.Mold pressing resin is poly (ether ether ketone) film, 1.5 meters of film breadth, 5 microns of thickness.Sticking mould number does not reach 50 times and uses √
It indicates, sticking mould number is not lower than 50 use × expressions.
