Radiation crosslinking polymethacrylimide foam and preparation method thereof |
| abstract |
The invention discloses a radiation crosslinking polymethacrylimide foam and a preparation method thereof, wherein the preparation method comprises the following steps: (1) mixing the raw materials uniformly, injecting the mixture into a closed plane mould, and carrying out polymerization reaction at the temperature of 30-60 ℃; (2) after the reaction solution is solidified and becomes a uniform transparent state, heating to 60-130 ℃ for post-polymerization treatment for 20-60h to obtain a poly (methyl) acrylimide pre-polymerization plate; (3) heating and foaming a poly (methyl) acrylimide prepolymerization plate at 180-260 ℃ to obtain the poly (methyl) acrylimide foam; (4) and (3) carrying out double-sided irradiation treatment on the poly (methyl) acrylimide foam under an electron accelerator to obtain the cross-linked poly (methyl) acrylimide foam. The mechanical property and the heat resistance of the poly (methyl) acrylimide foam prepared by the invention are obviously improved compared with the conventional foam. |
