| titleOfInvention |
A kind of polystyrene foam formula with wide processing window and preparation method thereof |
| abstract |
The invention relates to a polystyrene foaming formula with a wide processing window and a preparation method thereof. Due to the thermal insulation effect of the foamed material, it is not easy to control the temperature during the foaming process to be fully uniform and completely accurate. As the foaming density is getting lower and lower, it is more and more challenging to take into account the operable processing window in formula design. This creation uses the addition of a specific proportion of compatibilizers with a diblock copolymer polymer structure, a graft copolymer polymer structure or a side chain copolymer polymer structure to effectively improve and control the density of the polystyrene foam formulation in the high temperature processing range. Stability and reduced foam breakage. |
