Embodiment 1

[0027] The preparation of the epoxy acrylic resin of embodiment 1 adipic acid modification

[0028] Add 70 parts of epoxy resin E-51 (618) into a reaction kettle equipped with a stirrer, a thermometer and a dropping funnel, and add 12 parts of adipic acid with a dropping funnel when slowly heating to 60°C with an oil bath, and control it at Dropping is completed within 20 minutes, and then 0.5 parts of triphenyl antimony is added after the addition. Stop heating when the temperature rises to 80°C while stirring, and start to cool down when the system temperature rises to 100°C, and keep the system temperature between 80°C and 115°C for 1.5 hours. Use GB2895-82 to measure the acid value of the system. When the acid value is less than 5, add 15 parts of acrylic acid, and then add 1.8 parts of p-methoxyphenol and 0.7 parts of triphenyl antimony. After reacting at 115°C to 120°C for 2 hours, take a sample to measure the acid value, and when the acid value is less than 3, cool dow...

Embodiment 2

[0029] The preparation of the epoxy acrylic resin of embodiment 2 pimelic acid modification

[0030] Add 57 parts of epoxy resin E-44 (601) into the reaction kettle equipped with stirrer, thermometer and dropping funnel, and add 21 parts of pimelic acid with the dropping funnel when slowly heating to 60°C with an oil bath, and control it at The drop was completed within 30 minutes, and after the addition was completed, 11.5 parts of a mixture of N,N-dimethylbenzylamine and triphenylarsine were added. Stop heating when the temperature rises to 80°C while stirring, and start to cool down when the system temperature rises to 100°C, and keep the system temperature between 80°C and 115°C for 2 hours. Use GB2895-82 to measure the acid value of the system. When the acid value is less than 5, add 17 parts of acrylic acid, and then add 2.5 parts of hydroquinone and 1.0 parts of N, N-dimethylbenzylamine and triphenylarsine mixture. After reacting at 115°C to 120°C for 2.5 hours, take ...

Embodiment 3

[0031] The preparation of the epoxy acrylic resin of embodiment 3 azelaic acid modification

[0032]Add 64 parts of epoxy resin E-51 (618) into the reaction kettle equipped with stirrer, thermometer and dropping funnel, and add 16 parts of azelaic acid with the dropping funnel when slowly heating to 60°C with an oil bath, and control it at After the addition was completed within 15 minutes, 0.3 parts of a mixture of tetra-n-butylammonium bromide and triphenylantimony was added. Stop heating when the temperature rises to 80°C while stirring, and start to cool down when the system temperature rises to 100°C, and keep the system temperature between 80°C and 115°C for 2.5 hours. Use GB2895-82 to measure the acid value of the system. When the acid value is less than 5, add 18 parts of acrylic acid, and then add 1.0 parts of 1,4-naphthalenediol and 0.7 parts of tetra-n-butylammonium bromide and triphenyl antimony mixture. After reacting at 115°C to 120°C for 2.0 hours, take a samp...

Abstract

The invention discloses an epoxy acrylic acid resin and making method modified by multi-carbon straight-chain saturated fat diacid, which comprises the following parts: 50-75% epoxy resin, 10-30% straight-chain saturated fat diacid with main chain carbon number between 6 and 10, 10-30% acrylic acid, 0.3-0.5% catalyst, wherein the materials proceed ring-opening chain-extending reaction and esterifying reaction to produce the product.

Description

technical field [0001] The invention belongs to the field of paint adhesives, in particular to an epoxy acrylic resin. Background technique [0002] Epoxy acrylate is obtained by the esterification of epoxy resin with unsaturated monobasic acid such as acrylic acid or methacrylic acid, and is currently the most consumed photocurable oligomer in the domestic photocurable industry. Its important feature is that when any one of the various parts in its general formula is combined, a new epoxy acrylate vinyl ester resin can be derived. Epoxy acrylic resin has the characteristics of two kinds of thermosetting resins. On the one hand, it is similar to unsaturated polyester resin. Under the action of initiator, it reacts with free radicals to form an insoluble and infusible resin with a spatial network structure and a relatively high molecular weight. Large polymer with unsaturated group on the end group makes it have the properties of fast curing and easy processing of unsaturate...
