Problems solved by technology

[0006] The present invention provides a kind of removable glue, which is applied in the process of acousto-optic devices, and can overcome the problem that the prior art bonding layer is prone to appear due to low mechanical strength. Crack defects, the glue not only has excellent bonding strength, but also can repair the misplaced components by removing the glue when they fail due to misalignment during the bonding process

preparation example Construction

[0044] Another aspect of the present invention also provides a preparation method of removable glue, comprising the following steps:

[0045] (1) Slowly add the polymer into the organic solvent, while stirring until uniformly dispersed;

[0046] (2) Add curing agent, plasticizer, defoamer, coupling agent and stir evenly, seal and let stand for 3-6h;

[0047] (3) Open the lid and stir until the mixture is fully dissolved and becomes transparent, then seal and let stand for 12-36 hours.

[0048] When the composition of the glue does not contain defoaming agent or coupling agent, this operation is correspondingly omitted in the preparation step.

Abstract

The invention discloses removable glue and a preparation method thereof. The removable glue comprises the following components in parts by weight: 50-65 parts of a high-molecular polymer, 4-6 parts of a curing agent, 3-5 parts of a plasticizer and 20-30 parts of an organic solvent. The glue can be applied to process manufacturing of acousto-optic devices, has excellent bonding strength and is easy to operate, when a bonded element becomes a failure element due to dislocation, a bonded substance can be peeled off by removing the glue without damaging the element, so that the dislocated element can be repaired, and the peeled element can be used again.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a removable glue and a preparation method thereof, which can be applied to the technological manufacture of acousto-optic devices. Background technique [0002] In the acousto-optic device, the acousto-optic crystal and the transducer are bonded together by a bonding process after the bonding layer is respectively plated. The bonding layer of common acousto-optic devices is generally composed of a primer layer, an electrode layer, and a soldering layer. The soldering layer Choose a relatively soft metal (such as In), align the acousto-optic crystal coated with a bonding layer with the transducer, pressurize mechanically and maintain a constant pressure, and the metal atoms in the welding layer diffuse each other, so that the acousto-optic crystal and transducer energy devices bonded together, [0003] In high-frequency acousto-optic devices, the bonding layer is required to have...
