Description
Technical field
The invention discloses a kind of preparation method of release film and its application methods, belong to release film preparation technical field.
Background technique
With the progress of development of human civilization and science and technology, more and more electronic products are used for each neck of society
Domain, and external electronics industry pushes semiconductor to the strategic shift and home communications in China and the fast development of electronic industry
Industry and epoxy copperplate industry enter gold developing period, while will also drive the rapid development of its subsidiary industrial chain.It is making
Whens making printed circuit board, ceramic electronic components, thermoset resin article, decorative panel etc., release film is often sandwiched into process
It is used between metal plate or between resin, to avoid the bonding between metal plate or between resin.
Release film is called mold release film, refers to that surface has the film of separation property, release film is with specific material limited
Under the conditions of contact after do not have viscosity, or with slight viscosity.Under normal conditions in order to increase the off-type force of plastic film, meeting
Plastic film is done into plasma treatment, or applies fluorine processing, or applies organosilicon mould release on the surface layer of film material, as PET,
PE, OPP etc. allow it for a variety of different organic pressure sensitive adhesives, such as the pressure sensitive adhesive of hot melt adhesive, acrylic glue and rubber series,
It can show extremely light off-type force.But often to there is long-term high temperature resistance poor for existing release film, Temperature Size is stablized
Property it is poor, while release stability is bad, and the problem of release layer residual easily occur, destroy substrate appearance, therefore, seeking one kind has
Excellent release stability, release layer do not remain, can long-term high temperature resistant, appearance is flawless and has low cost, high economic benefit
Release film is extremely urgent.
Summary of the invention
Present invention mainly solves the technical issues of: for the long-term high temperature resistance of existing release film it is poor, Temperature Size is steady
Qualitative difference, while release stability is bad, release layer residual easily occurs, destroys the defect of substrate appearance, provides one kind and pass through
The compound trifluoroacetic acid of silicon dioxide gel makes it grow and be formed crystalline solid in nucleus calcium acetate particle surface, passes through fluorine-containing knot
Crystalline substance is loaded in pet film, is made fluorine atom modified film by heating anneal, is reduced film surface
Can, while in heating heating process, fluoride continues modified film surface energy after pyrolysis, and it is steady effectively to enhance release film high-temp.
First mixed sols liquid is made in ethyl orthosilicate and dehydrated alcohol, hydrochloric acid solution Hybrid Heating by qualitative method, the present invention, then
The mixing such as deionized water, trifluoroacetic acid, isopropanol are stood, mixed liquor and mixed sols liquid is collected and heat and rotate to doing, then
It handles, collects close with ethylene glycol terephthalate, antioxidant 1010 mix grinding, mixing after collecting gained drying crystalline ball milling sieving
Refining gained melting charge, which carries out hot pressing and annealing, last natural cooling, can obtain a kind of high adhesion rate release film of stabilization, this hair
Bright release film obtained has good flexibility, elasticity and release stability, while under long term high temperature environment, being still able to maintain
Preferable intensity is less prone to release layer residual condition, has preferable prospect of the application and market popularization value.
