Preferably, in the step (3), acrylic acid solution rate of addition is that 20s mono- drips.
As further preferably, the chilling temperature in the step (4) is 50 DEG C.
Compared with the prior art, beneficial effects of the present invention are embodied in:
(1) synthetic reaction of Epocryl is radical polymerization mechanism, and the grafting rate of polymerisation is impossible
100%, final product is the mixture of non-grafted epoxy resin, the epoxy resin being graft-polymerized and acrylic copolymer, by
The synthetic reaction of the provable Epocryl of the infrared spectrum of epoxy source material and synthesizing epoxy acrylate
Compare completely, target product has been made.
(2) with the increase of epoxy resin content, the transparency increase of Epocryl.Because work as ring
During oxygen resin content increase, active hydrogen atom number also increases therewith, this considerably increases acrylic monomers in epoxy resin master
The possibility being grafted on chain, and then cause the grafting rate increase of polymerization, the transparency increase of the Epocryl of synthesis.
(3) as the increase of polymeric reaction temperature, the transparency of Epocryl increase.Because reaction
Temperature is an important factor for influenceing graft copolymerization, and the hydrogen atom that initiator free radical is captured on methylene needs certain energy,
Energy is low when temperature is relatively low, is unfavorable for graft reaction.And high temperature is advantageous to the generation of graft reaction, so with polymerisation temperature
The raising of degree, the transparency increase of Epocryl.
(4) as the increase of initiator B PO contents, the glass transition temperature of the Epocryl of synthesis drop
It is low.Because the increase of initiator content causes the increase of free free-radical contents, and then increase the possibility of graft polymerization
Property.When grafting rate increases, side base increases, and this esters of acrylic acid side base is flexible, the presence phase of this flexible side group
When the effect of plasticizer in, so cause the glass transition temperature of Epocryl to decline.
(5) with the increase of initiator (BPO) content, number-average molecular weight, the weight average molecular weight of Epocryl
All decline therewith with Z-average molecular weight, and molecular weight distribution is totally on a declining curve, occasionally there is fluctuation.Because kinetic chain length
It is square directly proportional to initiator concentration, increase the content of initiator, the increase of free radical generating rate, chain termination speed also increases
Greatly, and the degree of polymerization then reduces, so synthetic resin adhesive force decline.It is also possible that the coupling between free radical growing chain
Terminate relevant.
(6) as the raising of drying temperature, the water resistance enhancing of film, toughness improve;And temperature it is too high when, adhesive force become
Difference;Film impact resistance change under different temperatures is little, but impact resistance is relatively preferable when temperature is 120~130 DEG C.
