Embodiment 1

[0062] The preparation of water-based temperature-controlled adhesive-release adhesive comprises the following steps:

[0063] Step 1: Weigh each raw material according to the mass percentage in Table 1, add the emulsifier to 60-80wt% (relative to all water addition) water, stir at a speed of 200r / min, stir for 15min, and mix well; heat up to 45°C , add tackifying resin, stir at 400r / min, disperse for 40min; cool down to room temperature, add a pH regulator to adjust the pH to 6, stir evenly, and obtain A liquid;

[0064] Step 2: In a protective atmosphere, add macromonomer, functional monomer and chain transfer agent to the liquid A obtained in the previous step, stir at a speed of 200r / min, and react at a temperature of 65°C for 1.5h to obtain liquid B;

[0065] Step 3: raise the temperature of liquid B to 75°C; keep the temperature at 75°C, add the initiator dropwise to liquid B, and dissolve the initiator with 10-30wt% (relative to all water addition) water in advance, and...

Abstract

The present invention relates to a water-based temperature-controlled adhesive release adhesive emulsion, a water-based temperature-controlled adhesive release adhesive obtained therefrom, and a preparation method thereof. The water-based temperature-controlled adhesive release adhesive emulsion is prepared from the following components according to mass percentage: monomer 40- 51%, functional monomer 1-5%, tackifying resin 1-5%, water 32-50%, pH regulator 0-0.8%, chain transfer agent 0.001-0.05%, initiator 0.1-0.5%, emulsifier 0.5‑5%, defoamer 0‑1%. Apply the water-based temperature-controlled adhesive-release adhesive emulsion on the base material to heat and solidify to make a water-based temperature-controlled adhesive-release adhesive, which has high adhesion at a certain temperature, can quickly reduce viscosity at low temperature, and is easy to peel without adhesive residue. , can be used for fixed processing of flexible substrates, optical lenses or semiconductors under UV irradiation and at different temperatures.

Description

technical field [0001] The invention relates to the technical field of polymer adhesive development, in particular to a water-based temperature-controlled adhesive-release adhesive emulsion, a water-based temperature-controlled adhesive-release adhesive obtained therefrom and a preparation method. Background technique [0002] In the processing of optical lens glass such as optical filters or semiconductor processing, such as single crystal silicon wafer processing, when cutting and grinding lens glass or semiconductor silicon wafers, it is usually necessary to use adhesives to assist in fixing, so as to avoid the Component movement causes damage. After processing, the processed product is easily peeled off from the fixed film without affecting the wafer material itself. At present, there are mainly two types of heat-reducing adhesives and UV-reducing adhesives on the market. The viscosity of the former is controlled by temperature, while the viscosity of the latter is cont...
