preparation example Construction

[0036] In the first aspect, the embodiment of the present invention provides a kind of preparation method of epoxy acrylic resin, and this preparation method comprises:

[0037] Step 101. Mix the epoxy resin, acrylic acid, phosphoric acid ester, catalyst, first polymerization inhibitor and antioxidant in the solvent at the first preset temperature to obtain an intermediate reaction system.

[0038] Step 102, raising the temperature of the intermediate reaction system to a second preset temperature for reaction, and terminating the reaction when the acid value is lower than 5 mg KOH / g to obtain an intermediate product of epoxy acrylate.

[0039] Step 103, making the epoxy acrylate intermediate product, the acid anhydride, and the second polymerization inhibitor in a preset ratio react at a third preset temperature to obtain an epoxy acrylic resin.

[0040] The preparation method of the epoxy acrylic resin provided in the embodiment of the present invention, by reacting phosphat...

Embodiment 1

[0081] This embodiment provides a kind of epoxy acrylic acid resin and preparation method thereof, the steps of this preparation method are as follows:

[0082] In step (1), at 60° C., o-formaldehyde epoxy resin (purchased from Baling Petrochemical, model CYD-208H) was dissolved in propylene glycol methyl ether acetate solvent to obtain an epoxy resin solution. Mix acrylic acid with 2-methyl-2-acrylic acid-2-(phosphonooxy)ethyl ester (the quality of 2-methyl-2-acrylic acid-2-(phosphonooxy)ethyl ester is the mass of acrylic acid 1%), and then added to the epoxy resin solution together with the catalyst triphenylphosphine, the polymerization inhibitor hydroquinone and the antioxidant 626 to obtain an intermediate reaction system. Wherein, the molar ratio of the epoxy group of o-formaldehyde epoxy resin to the carboxyl group of acrylic acid is 1:1, and the mass of catalyst, polymerization inhibitor and antioxidant is respectively the sum of the mass of o-formaldehyde epoxy resin,...

Embodiment 2

[0086] This embodiment provides a kind of epoxy acrylic acid resin and preparation method thereof, the steps of this preparation method are as follows:

[0087] In step (1), at 80° C., novolac epoxy resin (purchased from Baling Petrochemical, model CYDPN-048) was dissolved in diethylene glycol ether acetate to obtain an epoxy resin solution. Acrylic acid is mixed with hydrogen phosphate di(methacryloyloxyethyl) ester (the quality of hydrogen phosphate di(methacryloyloxyethyl) ester is 3% of acrylic acid quality), and then with catalyst triethylamine, barrier Polymerizing agent methyl hydroquinone and antioxidant 264 are added to the epoxy resin solution together to obtain an intermediate reaction system. Wherein, the mol ratio of the epoxy group of novolak epoxy resin and the carboxyl group of acrylic acid is 1:1.5, and the addition amount of catalyst, polymerization inhibitor and antioxidant is respectively relative to novolak epoxy resin, acrylic acid and phosphoric acid est...

Abstract

The invention discloses a preparation method of an epoxy acrylic resin, and belongs to the field of high molecular material. The preparation method comprises following steps: at a first preset temperature, an epoxy resin, acrylic acid, a phosphate, a catalyst, a first polymerization inhibitor, and an antioxidant are mixed to be uniform in a solvent at a preset ratio so as to obtain an intermediatereaction system; the intermediate reaction system is heated to a second preset temperature for reaction, when the acid value is lower than 5mg KOH / g, reaction is stopped so as to obtain an epoxy acrylate intermediate; the epoxy acrylate intermediate, an acid anhydride, and a second polymerization inhibitor are reacted at a third preset temperature so as to obtain the epoxy acrylic resin. The prepared epoxy acrylic resin possesses high clunging force and excellent chemical stability, and is capable of solving a compatibility problem of phosphate structure with epoxy resin.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to an epoxy acrylic resin and its preparation method and application. Background technique [0002] Epoxy acrylic resin is a common developing resin, which is usually used to prepare PCB ink (Printed Circuit Board, printed circuit board), so it is very necessary to provide an epoxy acrylic resin. [0003] The prior art provides such an epoxy acrylic resin, which is prepared by the following method: put the raw material epoxy resin and 1,2-cyclohexanediol diglycidyl ether in different proportions into the reactor, stir and heat up to 80 -90°C, then add the measured catalyst, then use a constant pressure dropping funnel to hold acrylic acid and polymerization inhibitor for dropwise addition, control the dropwise addition within 0.5-1.0h; start timing after the dropwise addition, gradually increase the temperature, and react After 1 hour, start to measure the acid value, and stop the ...
