Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an acrylic resin lens packaging tape and its preparation method, which solves the problems of high temperature retention, sealing water permeability and lens resin liquid compatibility of the materials currently used to prepare lens packaging tapes. etc. are poor, the thickness cannot be thinned and the cost is high, so that the lens packaging tape is easily deformed and damaged under some conditions, and the resin lens is unqualified, which is not conducive to the preparation of stable and good quality, cost-effective lens packaging tape, and the current lens packaging The glue is generally prepared with low-efficiency, unstable batches of oil-based pressure-sensitive adhesives, which are difficult to meet the technical requirements of easy mold opening, no whitening, no glue residue, no gaps, and no deformation in lens production.

[0037] A kind of preparation method of the encapsulation tape of acrylic resin lens, concrete operation steps are as follows:

[0038] 1) Glue preparation: Install the stirrer, reflux condenser and constant pressure dropping funnel on a 1000mL four-necked flask, turn on the water bath, raise the temperature to 76°C-78°C, and mix a certain ratio of each Mix monomers, initiators, additives and deionized water, add the uniformly mixed solution into the constant pressure dropping funnel, when the temperature reaches the set temperature, add 1 / 3 of the mixed solution from the constant pressure dropping funnel As a monomer pre-emulsified solution, stir at a rate of 200r / min at the same time. When there is a reflux phenomenon in the four-necked flask, start to add the remaining mixed solution dropwise, and the dropwise addition is completed within 3.0h-4.5h. Finally, conduct a heat preservation reaction at 82°C to 84°C, which takes about 3 hours, and then cool with cold water. When t...

[0042] Glue preparation steps: install the stirrer, reflux condenser and constant pressure dropping funnel on a 1000mL four-necked flask, turn on the water bath, and raise the temperature to 76°C-78°C. According to the designed formula, mix various monomers, initiators, additives and deionized water in a certain ratio, and put the evenly mixed solution into the constant pressure dropping funnel. Add 1 / 3 of the mixed solution into the dropping funnel as the monomer pre-emulsified solution, and stir at a speed of 200r / min at the same time. When there is a reflux phenomenon in the four-necked flask, start to drop the remaining mixed solution. The dropwise addition is completed within h-4.5h. After the dropwise addition is completed, carry out a heat preservation reaction at 82°C to 84°C for about 3 hours, and then cool with cold water. When the temperature drops below 40°C, filter with 120 mesh and discharge .

Abstract

The invention discloses an acrylic resin lens packaging adhesive tape and a preparation method thereof, the acrylic resin lens packaging adhesive tape comprises an adhesive layer and a PET film material layer, wherein the adhesive layer adopts water-based acrylic acid glue, and the invention relates to the technical field of adhesive tapes. According to the packaging adhesive tape for the acrylicresin lens and the preparation method of the packaging adhesive tape, the invention solves the problems that an existing material for preparing the lens packaging adhesive tape is poor in high-temperature retentivity, sealing water permeability, lens resin liquid matching performance and the like, the thickness cannot be reduced, the cost is high, and the lens packaging adhesive tape is prone to deformation and damage under some conditions are solved;.

Description

technical field [0001] The invention relates to the technical field of adhesive tapes, in particular to an acrylic resin lens packaging adhesive tape and a preparation method thereof. Background technique [0002] When making spectacle lenses, spectacle lens molds need to be used. After the mold is filled with spectacle resin liquid, the upper and lower molds are sealed with tape, and then the finished spectacle lenses are produced by high-temperature baking. When sealing the upper and lower molds, the quality of the tape Regarding the quality of the spectacle lenses produced, when the tape quality is poor, fogging, residual glue, self-release, etc. will easily occur after the mold is baked at high temperature, resulting in the production of defective spectacle lenses, so we have to provide customers with a A suitable tape product to ensure the quality of the customer's finished spectacle lenses; [0003] See (Chinese Patent CN 207581722 U Danyang Winnie Optics Co., Ltd. 20...
