On January 25, limited company of new to Anhui Jiala material produces per year bureau of environment of organisms' habits of town of lake of overgrown with weeds of transaction of influence of environment of project of new material of 20 thousand tons of electrons before approving fair show.
Enclosing glue is to be used at enclosing electronic parts, it is to rise sealed, cover or the glue of a kind of electron that fill seals or adhesive. Electronic parts arrives via after the electron encloses glue, can rising waterproof, moistureproof, shock-proof, dustproof, anticorrosion, medicinal powder hot, confidential the action that wait. Accordingly, the electron encloses glue to need to have be able to bear or endure on any account is lukewarm, interpose report intensity is high, insulating properties is good, environmental protection brings complete characteristic. Promote the science and technology such as electron, software, chip the distribution of the domain energetically as the country, the rapid development of domestic electron industry, demand of market of epoxy resin of electric sub level expands ceaselessly.
Project general situation
Project name: Produce per year project of new material of 20 thousand tons of electrons
Project property: Build
Build a place: Inside area of garden of chemical industry of development of technology of economy of lake of overgrown with weeds
Build an unit: Limited company of data of Anhui Jia Laxin
Construct content and scale: The project covers an area of a face to accumulate 28307 square metre, total floor area 17000 square metre, useless of short duration of area of center of construction production workshop, storehouse, multi-purpose building, power, canister and danger puts the support features such as the library, project building the year after next produces 20 thousand tons of double phenolic A epoxy resin;
The project invests: 360 million yuan
Construction is periodic: October 2023 ~2025 year in August
The electron encloses with epoxy resin:
As circuit of large scale integration and electron yuan the ceaseless development that miniature of parts of an apparatus changes, electron yuan of parts of an apparatus medicinal powder hot issue becomes the crucial issue that affects its service life, urgent need is had good medicinal powder the adhesive of tall heat conduction of hot property serves as enclose material. Epoxy resin has sex of report of admirable hear resistance, insulating property, adherence, interpose, mechanical function and lesser shrinkage, be able to bear or endure chemical sex, there are better processability and maneuverability again after adding solidify agent. Accordingly, foreign semiconductor device is at present more use epoxy resin to undertake enclosing.
As environmental protection cry increasingly rising and what integrated circuit industry encloses material function to ask to the electron is ceaseless rise, raised taller requirement to epoxy resin. IC encloses used epoxy resin besides requirement tall purity, concussion of low stress, heat-resisting and low water imbibition also are the problem that solves urgently. In the light of high temperature resistant wait for a problem with low bibulous rate, domestic and international research sets out from molecular structure design, basically center at mixing the synthesis of modified and new-style epoxy resin in all, wait for couplet benzene, naphthalene, sulphone on one hand base group and fluorine element introduce in annulus oxygen framework, after raising solidify of material be able to bear or endure function of damp and hot; On the other hand, have representative solidify agent through joining a few kinds, temperature of transition of kinetic, vitrification, pyrolysis temperature mixes the solidify that studies condensate the function such as bibulous rate, preparation of do one's best gives high-powered electron to enclose material to use epoxy resin.
