Description
Technical field
The present invention relates to the bonding and Strengthening Technology field of organosilicon material, in more detail can improve the adhesion promoters of add-on type liquid silicon rubber adhesiveproperties and mechanical property.The invention still further relates to the preparation method and application of described adhesion promoters.
Background technology
The world today, scientific and technical fast development, the mankind have entered the electronic information epoch.Along with the continuous progress of electronic technology, that electronic component, logical circuit are tending towards day by day is integrated, miniaturization and modularization, and Working environment is harsher, and the stability in use of electron device is had higher requirement.Encapsulation is one of important procedure of electronic devices and components, it can the strengthening electronic device globality, prevent moisture, dust and obnoxious flavour to the erosion of electronic devices and components, improve the resistibility to external shock, vibrations, stablize component parameter, and be conducive to miniaturization and the lightweight of device.
Electronic package material commonly used mainly contains Resins, epoxy, urethane and organosilicon material three major types at present.Wherein, add-on type liquid silicon rubber can keep elasticity at-60～200 ℃ long-term, does not absorb heat during curing, not heat release, do not shrink after the curing, and having good electrical property and chemical stability, energy water-fast, anti-ozone, weather-proof becomes one of high performance packaged material.Although add-on type liquid silicon rubber has the incomparable advantage of other packaged material, himself also has some problems.Be nonpolar organic group such as add-on type liquid silicon rubber in the sulfuration rear surface overwhelming majority, show low internal cohesive energy (Silicone sealants and structural adhesives.International Journal of Adhesion ﹠amp; Adhesives; 2001; 21 (5): 411-422); thereby poor to the cementability of other material; moisture causes corrosion and failure of insulation by the infiltration inside of electronic component of the space between silicon rubber and the base material easily in use; in the environment of harshness even can come off with base material, make electron device lose seal protection, limited to a certain extent its range of application.
In order to address the above problem, the cementability that how to improve add-on type liquid silicon rubber and base material some researchs have been carried out both at home and abroad.At present, mainly contain three kinds of methods: the one, substrate surface is processed, comprise that shortcoming is to need additional production process, has reduced production efficiency, has increased production cost with silane coupling agent pretreating substrates surface, with measures such as Cement Composite Treated by Plasma substrate surfaces; The 2nd, by changing the molecular structure of polysiloxane, make add-on type liquid silicon rubber itself have cementability, but because this preparation process more complicated realizes that suitability for industrialized production is subject to larger restriction with applying; The 3rd, by adding adhesion promoters, made add-on type liquid silicon rubber solidify the rear cementability that obtains.
Chinese patent CN102408869A discloses a kind of with vinyl front three (second) TMOS and γ-(2,3-epoxy the third oxygen) propyl group front three (second) TMOS has the add-on type liquid silicon rubber adhesion promoters of certain cementability by hydrolysis reaction or both hydrolysis reaction products and γ-aminopropyl front three (second) TMOS reaction preparation to aluminium, but there is the bad control of hydrolysis reaction condition of siloxanes, reaction process produces gel easily, and nitrogenous compound makes the shortcomings such as Pt catalyst poisoning easily.European patent EP 2158285B1 has reported a kind of synthetic silicoorganic compound with at least one benzene ring structure, at least one alicyclic epoxy base and at least one Si-H base of addition reaction of silicon with hydrogen that utilize, and it is added in the silicon rubber can make the sealing material that the electrolytic thin-membrane in the fuel cell is produced good bonding.Chinese patent CN102010598A also reported a kind of utilize addition reaction of silicon with hydrogen synthetic contain the organo-siloxane that has allyl group, epoxy group(ing) and organic siloxy-on trimerization isocyanide acyl ring and the per 1 molecule trimerization isocyanide acyl ring; by add this adhesion promoters to silicon rubber, can make the thermoplasticss such as itself and liquid crystalline polymers produce good bonding.But all have the bad control of addition reaction of silicon with hydrogen condition, platinum catalyst is removed the shortcomings such as difficulty.
Although at present to the more existing reports of the adhesion promoters that improves the add-on type liquid silicon rubber cementability, but adhesiveproperties is only studied in these work mostly, does not but have relevant report for the adhesion promoters that can improve simultaneously add-on type liquid silicon rubber adhesiveproperties and mechanical property.Because organo-silicone rubber has the amorphism structure, its macromolecular chain is very submissive, and is extremely low without the organo-silicone rubber intensity of reinforcement a little less than the interchain interaction power, almost has no value for use.Therefore, developing the add-on type liquid silicon rubber adhesion promoters with strengthening action has great importance.
