[0022] In view of this, the present invention proposes a method for preparing a polymerizable resin, aiming at reducing the cost of existing water-based photoinitiated coatings and inks so that they can be popularized on a large scale. In one embodiment, the preparation method of the polymerizable resin comprises the following steps:
[0023] Step S10, uniformly mixing maleic anhydride and the first raw material to obtain a first solution;
[0024] In this embodiment, the first raw material includes at least one of methyl methacrylate, butyl methacrylate, styrene, methyl acrylate, and butyl acrylate. That is, the first raw material may be any one or a mixture of more of the above five substances.
[0025] Wherein, in the first solution, the mass fraction of the maleic anhydride is 5-50%. That is, the mass fraction of the first raw material is 50-95%. The present invention does not limit the specific components and proportions of the first raw materials, which are formulated...
Embodiment 1
[0045] (1) uniformly mixing maleic anhydride and styrene to obtain a first solution (wherein, the mass fraction of maleic anhydride is 5%);
[0046] (2) Add azobisisobutyronitrile to the first solution, mix uniformly to obtain a second solution, add the second solution dropwise to acetone while stirring to obtain a mixed solution, and mix the mixed solution Raise the temperature to 100°C for the polymerization reaction to occur. After the reaction is completed, a prepolymer solution is obtained, wherein the amount of the initiator added is 0.3% of the mass of the first solution, and the volume ratio of the organic solvent to the first solution is 2:1 ;
[0047] (3) At 100°C, add hydroxyethyl acrylate, hydroxyethyl methacrylate, hydroxythioxanthone, photoinitiator 1173 and photoinitiator 184 to the prepolymer solution, wherein the acrylate hydroxy The mass ratio of ethyl ester, hydroxyethyl methacrylate, hydroxythioxanthone, photoinitiator 1173, photoinitiator 184 to the polym...
Embodiment 2
[0049] (1) Mix maleic anhydride and methyl methacrylate uniformly to obtain a first solution (wherein, the mass fraction of maleic anhydride is 20%);
[0050] (2) add dibenzoyl peroxide in the first solution, mix homogeneously, obtain the second solution, drop the second solution into the propylene glycol methyl ether acetate solution while stirring, obtain the mixed solution, The temperature of the mixed solution is raised to 80° C. to undergo a polymerization reaction. After the reaction is completed, a prepolymer solution is obtained, wherein the amount of the initiator added is 1% of the mass of the first solution, and the volume ratio between the organic solvent and the first solution is The ratio is 1.5:1;
[0051] (3) At 80°C, add hydroxyethyl acrylate, hydroxyethyl methacrylate, hydroxythioxanthone, photoinitiator 1173 and photoinitiator 184 to the prepolymer solution, wherein the acrylate hydroxy The mass ratio of ethyl ester, hydroxyethyl methacrylate, hydroxythioxa...
