specific Embodiment approach 1

[0028] Specific embodiment 1: This embodiment is a cationic ultraviolet light and heat dual deep-curing adhesive consisting of 60 to 100 parts of oligomeric resin mixture containing epoxy groups, 5 to 30 parts of diluent, It is prepared by 5-15 parts of coupling agent, 0.75-3 parts of photoinitiator, 0.75-3 parts of photosensitizer, 0.075-0.5 part of thermal initiator and 0-0.2 part of thermal stabilizer.

[0029] The advantage of this implementation mode:

[0030] 1. A cationic ultraviolet light and heat dual deep-curing adhesive prepared in this embodiment is cured by dual initiation means of ultraviolet light and heat. After being irradiated by ultraviolet light, it reacts rapidly, and at the same time, the heat generated by ultraviolet light is used to initiate a thermal curing reaction. process, so as to achieve rapid deep curing;

[0031] 2. A cationic ultraviolet light and heat double deep-curing adhesive prepared in this embodiment does not need post-heating to initia...

specific Embodiment approach 2

[0036] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the described oligomeric resin mixture containing epoxy groups is prepared according to the following steps:

[0037]Heat the resin containing bifunctional epoxy groups from room temperature to 60°C to 80°C at a stirring speed of 100r / min to 150r / min; Add oligomers containing multifunctional epoxy groups at 60°C to 80°C; then stir and react at a stirring speed of 150r / min to 200r / min and a temperature of 60°C to 80°C for 6h to 18h , to obtain an oligomeric resin mixture containing epoxy groups;

[0038] The mass ratio of the bifunctional epoxy group-containing resin to the polyfunctional epoxy group-containing oligomer is 100:(5-40). Other steps are the same as in the first embodiment.

specific Embodiment approach 3

[0039] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the resin containing difunctional epoxy groups is alicyclic epoxy resin, diester chain alicyclic epoxy Resin, aliphatic epoxy resin, bisphenol A epoxy resin and hydrogenated bisphenol A epoxy resin or a mixture of several thereof; the alicyclic epoxy resin is 3,4-epoxy ring Hexylmethyl 3,4-epoxycyclohexyl carboxylate; diester chain aliphatic epoxy bis((3,4-epoxycyclohexyl)methyl)adipate; aliphatic epoxy resin For ethylene glycol diglycidyl ether. Other steps are the same as those in Embodiment 1 or 2.

Abstract

A cationic UV and heat dual deeply-curing adhesive and its preparation method relate to a curing adhesive and its preparation method. The invention aims to solve the problem that an existing UV curing adhesive cannot achieve rapid deep curing and still needs subsequent heating after UV-irradiation. The UV and heat dual deeply-curing adhesive is prepared from, by weight, 60-100 parts of an oligomer resin mixture containing an epoxy group, 5-30 parts of a diluent, 5-15 parts of a coupling agent, 0.75-3 parts of a photoinitiator, 0.75-3 parts of a photosensitizer, 0.075-0.5 part of a thermal initiator and 0-0.2 part of a heat stabilizer. The method comprises the following steps: 1, weighing; and 2, mixing to obtain the cationic UV and heat dual deeply-curing adhesive. According to the invention, a cationic UV and heat dual deeply-curing adhesive and its preparation method can be obtained.

Description

technical field [0001] The invention relates to a curing adhesive and a preparation method thereof. Background technique [0002] UV-curable adhesive is a kind of high-efficiency, environment-friendly and energy-saving adhesive. It not only has the advantages of no solvent and long storage time, but also has the advantages of fast curing speed and instant curing. However, because UV-curable adhesives rely on ultraviolet light to initiate curing, their curing depth is limited by ultraviolet radiation, and it is difficult to realize the application of colored systems. At the same time, it is difficult to realize the curing process in the shadow area of ​​the system. Subject to application limitations. [0003] The curing depth of UV-curable adhesives is affected by many factors. The factors affecting the light source mainly include the intensity of the curing light source, the projection distance of the light source, and the projection time. By increasing the intensity of ult...
