Description
Technical field
The invention discloses a kind of preparation method of high-temperature stable mould release membrance, belong to mould release membrance preparing technical field.
Background technology
With the progress of Development of Human Civilization and science and technology, increasing electronic product is used for each neck of society
Domain, and external electronics industry promotes semiconductor to the strategic shift and home communications of China and the fast development of electronic industry
Industry and epoxy copperplate industry enter gold developing period, while will also drive developing rapidly for its subsidiary industrial chain.In system
When making printed circuit board, ceramic electronic components, thermoset resin article, decorative panel etc., mould release membrance is often sandwiched into operation
Used between metallic plate, or between resin, the bonding to avoid between metallic plate or between resin.
Mould release membrance is called mold release film, refers to the film that surface has separation property, and mould release membrance is with specific material limited
Under the conditions of contact after without viscosity, or with slight viscosity.Under normal circumstances in order to increase the off-type force of plastic sheeting, meeting
Plastic sheeting is done into plasma treatment, or applies fluorine treatment, or apply organosilicon mould release on the top layer of film material, such as PET,
PE, OPP etc., allow it for a variety of organic pressure sensitive adhesives, such as pressure sensitive adhesive of hot melt adhesive, acrylic glue and rubber series,
Extremely light off-type force can be shown.But, it is poor often to there is long-term resistance to elevated temperatures in existing mould release membrance, Temperature Size stabilization
Property it is poor, while release stability is not good, easily occur release layer residual, destroy base material outward appearance problem, therefore, seeking one kind has
Excellent release stability, release layer is not remained, can high temperature resistant for a long time, outward appearance is flawless and with economic benefit inexpensive, high
Mould release membrance is extremely urgent.
The content of the invention
Present invention mainly solves technical problem：Poor for the long-term resistance to elevated temperatures of existing mould release membrance, Temperature Size is steady
, while release stability is not good, easily there is release layer residual in qualitative difference, destroys the defect of base material outward appearance, there is provided one kind passes through
Silicon dioxide gel is combined trifluoroacetic acid, it is grown in nucleus calcium acetate particle surface and is formed crystalline solid, by fluorine-containing knot
Crystalline substance is loaded in pet film, and fluorine atom modified film is made by heating anneal, reduces film surface
Can, while in intensification heating process, fluoride continues modified film surface energy after pyrolysis, effectively strengthens release film high-temp. steady
Qualitatively method, of the invention that tetraethyl orthosilicate and absolute ethyl alcohol, hydrochloric acid solution Hybrid Heating first are obtained into mixed sols liquid, then
Deionized water, trifluoroacetic acid, isopropanol etc. are mixed and is stood, collected mixed liquor and mixed sols liquid and heat and rotate to dry, then
Processed with ethylene glycol terephthalate, antioxidant 1010 mix grinding, banburying after collecting the ball milling sieving of gained drying crystalline, collected close
Refining gained melting charge carries out hot pressing and annealing, and last natural cooling a kind of can stablize adhesion rate mould release membrance high, this hair
Bright obtained mould release membrance has good flexibility, elastic and release stability, while under long term high temperature environment, remaining to keep
Preferable intensity, is less prone to release layer residual condition, with preferable prospect of the application and market popularization value.
