The content of the invention
This uses OCA optical cements to solve the above problems the invention provides explosion-proof in a kind of mobile phone, and service life is long, environmental protection Effect is good, and saves the energy, moderate.
The technical scheme that the present invention is provided is：It is explosion-proof in a kind of mobile phone to use OCA optical cements, by following mass percentage content Material it is reacted after be made：
By said components, example is sequentially added in stirred tank by mass percentage, natural after being mixed evenly under the conditions of lucifuge Stand froth breaking and glue is made, then by the glue application one side that sided corona treatment is crossed on PET mould release membrances, enclose and lead to after silicon mould release membrance Cross UV solidifications；
Wherein, acrylic polymer by the material of following weight/mass percentage composition it is reacted after be made：
The molecular weight regulator is in n-dodecyl mercaptan, tert-dodecylmercaotan, the different monooctyl ester of tri-thiol propionic acid It is one or more；
First weigh 1/2 above-mentioned amount Isooctyl acrylate monomer add reactor, then weigh above-mentioned amount methyl methacrylate, Methacrylic acid -2- ethylhexyls, hydroxy-ethyl acrylate, molecular weight regulator sequentially add in reactor and continue stirring, Remaining 1/2 Isooctyl acrylate monomer for having dissolved azo dibutyronitrile is added drop-wise in reactor while heating to reactor material And continuing stirring, reactor is warming up to 80~90 DEG C and is incubated 3 hours, then naturally cools to normal temperature.
As optimization, initiator is 1- hydroxycyclohexyl phenyl ketones or/and 2,4,6- trimethylbenzoy-diphenies Phosphine oxide.
The beneficial effects of the present invention are explosion-proof in mobile phone to use OCA optical cements, service life is long, weatherability, yellowing resistance Good, environmental protection effect is good, excellent performance, moderate.
