Embodiment 1
[0023] A kind of triglycidyl isocyanurate (TGIC) through physical coating, its raw material composition component and its weight are as follows:
[0024] 10 parts of glycidyl acrylic resin;
[0025] TGIC 90 copies;
[0026] The triglycidyl isocyanurate is uncoated triglycidyl isocyanurate, and the epoxy value is greater than or equal to 0.92eq / 100g.
[0027] The above-mentioned preparation method of triglycidyl isocyanurate through physical coating, the steps are as follows:
[0028] Add the two materials with a certain mass ratio to the high-speed mixer, crush and mix at high speed for 3-20min, and then extrude through the twin-screw extruder. The temperature in the first zone is 80-90℃, and the temperature in the second zone is 100-120℃ ℃, melting, kneading, extruding, cooling, and tableting to become a flaky milky white solid, that is, physically coated triglycidyl isocyanurate;
[0029] The residence time of the two materials in the molten state in the screw of the twin...
