Embodiment 1
[0026] A method for preparing and using a heat-conducting pressure-sensitive adhesive tape, the mass percentage of each raw material is as follows:
[0027] Component Proportion Aluminum oxide 40% solvent 20% Modified Acrylic Resin 15% Normal temperature curing agent 1% Polyester polyol 15% Adhesion promoter 1% filler dispersant 2% Filler coupling agent 1% Closed Polyurethane Curing Agent 5%
[0028] First add aluminum oxide, solvent, filler dispersant, and filler coupling agent into the stirring tank, disperse at high speed for 3 minutes, then add the rest of the components into the stirring tank, and continue stirring for 40 minutes to prepare a heat-conducting pressure-sensitive adhesive; Use the heavy-release protective film as the coating substrate, coat the heat-conducting pressure-sensitive adhesive on it, dry it in a gradient oven at 50°C, attach the light-release protective film, and ripen for 0-7 day...
Embodiment 2
[0031] A method for preparing and using a heat-conducting pressure-sensitive adhesive tape, the mass percentage of each raw material is as follows:
[0032] Component Proportion fumed silica 30% solvent 25% Modified Acrylic Resin 15% Normal temperature curing agent 1% epoxy resin 20% Adhesion promoter 1% filler dispersant 2% Filler coupling agent 1% Epoxy curing agent 5%
[0033] First add fumed silica, solvent, filler dispersant, and filler coupling agent into the stirring tank, disperse at high speed for 10 minutes, then add the rest of the components into the stirring tank, and continue stirring for 40 minutes to prepare a heat-conducting pressure-sensitive adhesive; Use the heavy-release protective film as the coating substrate, coat the heat-conducting pressure-sensitive adhesive on it, and after drying in a gradient oven at 50°C, attach the light-release protective film; after 1-3 days of aging, that is ...
Embodiment 3
[0036] A method for preparing and using a heat-conducting pressure-sensitive adhesive tape, the mass percentage of each raw material is as follows:
[0037] Component Proportion Aluminum oxide 30% solvent 25% Modified Acrylic Resin 15% Normal temperature curing agent 1% UV curable resin 20% Adhesion promoter 1% filler dispersant 2% Filler coupling agent 1% light curing agent 5%
[0038] First add aluminum oxide, solvent, filler dispersant, and filler coupling agent into the stirring tank, disperse at high speed for 20 minutes, then add the rest of the components into the stirring tank, and continue stirring for 30 minutes to prepare a heat-conducting pressure-sensitive adhesive; The heavy-release protective film is used as the coating substrate, and the heat-conducting pressure-sensitive adhesive is coated on it. After drying in a gradient oven at 70°C, the light-release protective film is attached to obtain a...
