preparation example Construction

[0053] The present invention also provides a kind of preparation method of adhesive, it comprises the steps:

[0054] Mixing the raw material components in the first component to obtain a mixed solution;

[0055]Add the second component to the mixed liquid in stages and mix; the first stage is, under the protective gas, add a part of the second component to the mixed liquid, and react at 50-60°C for 1-1.5h , the second stage is: add the remaining second component to the mixed solution, react at 75-80° C. for 2-3 hours, and cool down to obtain the adhesive.

[0056] Among them, the addition of the second component in stages is conducive to the full polymerization of the monomeric substances in the adhesive to form polyhydroxyacrylic acid resin, which is beneficial to obtain an adhesive that has good adhesion at high temperature and is not easy to leave residual glue after laminating the product.

[0057] The present invention also provides a coating tool suitable for making th...

Abstract

The invention provides an adhesive, a protection film containing the adhesive and a coating tool. The adhesive comprises a first component and a second component which are independently subpackaged, wherein the first component is prepared from the following raw material components in parts by mass: 35 to 50 parts of ethyl methacrylate, 10 to 20 parts of 2-ethylhexyl acrylate, 0.8 to 2 parts of 2-hydroxyethyl methacrylate, 0.8 to 2 parts of itaconic acid, 0.5 to 1.5 parts of blocked isocyanate and 80 to 90 parts of a solvent, and the second component is prepared from the following raw material components in parts by mass: 0.5 to 1 part of an initiator. The protection film prepared from the adhesive is large in adhesive force at high temperature, easy to peel off after cooling and free of adhesive residue.

Description

technical field [0001] The invention belongs to the technical field of adhesive tapes, and in particular relates to an adhesive, a protective film containing the adhesive and a coating tool. Background technique [0002] During the processing of semiconductor devices (displays), high temperature steps such as vacuum sputtering and evaporation are usually required. In order to prevent cracking and damage to components caused by high temperature treatment, it is often necessary to use protective films to protect and fix the components. Traditional protective films encounter At high temperature, the heat resistance is poor, and it is easy to fall off, but it is not easy to peel off after cooling. Contents of the invention [0003] The object of the present invention is to provide an adhesive with strong adhesive force at high temperature, easy to peel off after cooling and no glue residue, and a protective film containing the adhesive to solve the problem that the existing pr...
