Embodiment 1

[0019] A preparation method of optical adhesive, comprising the following steps:

[0020] Step 1, raw material preparation, by weight, get respectively 3 parts of shellac sheet, 1 part of rosin and 0.5 part of calcium carbonate powder three kinds of raw materials, stand-by;

[0021] Step 2, heating and melting the rosin, then adding the shellac flakes, stirring it with a clean stirring rod, and continuing to heat until the shellac flakes are melted and mixed evenly with the rosin to obtain a mixed solution A;

[0022] Step 3. Add calcium carbonate powder to the mixed solution A, keep the molten state of the mixed solution A, and continue to mix and stir it with a clean stirring rod until the calcium carbonate powder is evenly dispersed in the mixed solution A to obtain a mixed solution B;

[0023] Step 4. Take a clean and water-free storage tank, pour the mixed solution B into the storage tank, and then cool to room temperature.

[0024] When in use, heat the optical adhesiv...

Embodiment 2

[0026] A preparation method of optical adhesive, comprising the following steps:

[0027] Step 1, raw material preparation, by weight, get respectively 4 parts of shellac sheet, 2 parts of rosin and 1 part of calcium carbonate powder three kinds of raw materials, stand-by;

[0028] Step 2, heating and melting the rosin, then adding the shellac flakes, stirring it with a clean stirring rod, and continuing to heat until the shellac flakes are melted and mixed evenly with the rosin to obtain a mixed solution A;

[0029] Step 3. Add calcium carbonate powder to the mixed solution A, keep the molten state of the mixed solution A, and continue to mix and stir it with a clean stirring rod until the calcium carbonate powder is evenly dispersed in the mixed solution A to obtain a mixed solution B;

[0030] Step 4. Take a clean and water-free storage tank, and lay release paper in the storage tank. The release paper is used to prevent the mixed liquid B from directly contacting the tank...

Embodiment 3

[0033] A preparation method of optical adhesive, comprising the following steps:

[0034] Step 1, raw material preparation, by weight, get respectively 6 parts of shellac sheet, 3 parts of rosin and 2 parts of calcium carbonate powder three kinds of raw materials, stand-by;

[0035] Step 2, heating and melting the rosin, then adding the shellac flakes, stirring it with a clean stirring rod, and continuing to heat until the shellac flakes are melted and mixed evenly with the rosin to obtain a mixed solution A;

[0036] Step 3. Add calcium carbonate powder to the mixed solution A, keep the molten state of the mixed solution A, and continue to mix and stir it with a clean stirring rod until the calcium carbonate powder is evenly dispersed in the mixed solution A to obtain a mixed solution B;

[0037] Step 4. Take a clean and water-free storage tank, and lay release paper in the storage tank. The release paper is used to prevent the mixed liquid B from directly contacting the tan...

Abstract

The invention discloses a preparation method of an optical adhesive. The preparation method comprises steps as follows: S1, three raw materials including shellac, rosin and calcium carbonate powder are taken respectively according to the designed matching ratio; S2, rosin is heated to be molten, shellac is added, the mixture is stirred with a stirring rod, and a mixed solution A is obtained; S3, calcium carbonate powder is added to the mixed solution A, and a mixed solution B is obtained; S4, the mixed solution B is poured into an accommodating tank and cooled to the room temperature, and the optical adhesive can be obtained. The optical adhesive has the characteristics of being low in cost, high in adhesion strength, convenient to use, free of toxicity and pollution, easy to clear and the like; when a crystal blank is required to be taken down by removing the adhesive, the adhesive can be directly and integrally torn down or can be directly and integrally torn down after heating and softening, the adhesive cannot adhere to the surface of the crystal blank, the cleanliness of the surface of the crystal blank is kept better, the adhesive is convenient and efficient to use, and besides, the adhesive is lower in loss, can be repeatedly used and is suitable for processing.

Description

technical field [0001] The invention relates to the use of an adhesive during cutting and processing of hard materials such as laser crystals, in particular to a preparation method of an optical adhesive used for bonding and fixing. Background technique [0002] In laser crystal production and processing enterprises, when cutting crystal blanks, it is often necessary to use adhesives. The role of the adhesive is to fix the crystal blanks on the cutting equipment to facilitate their cutting. However, existing The effect of the adhesive used is often unsatisfactory, and there will always be problems in various aspects. For example, some companies use AB glue for bonding and fixing. The bonding process is inconvenient to operate, and it takes time and effort to remove the crystal blank. The crystal blank is placed in industrial acetone for several hours or more than ten to twenty hours, and the cured AB glue is soaked until it is softened, and then it can be removed. This metho...
