| titleOfInvention | A foam with smooth surface and recoverable crease marks and preparation method |
| abstract | The invention discloses a foam with smooth surface and recoverable crease marks and a preparation method, and belongs to the field of foam sheets. It is a thick foam of irradiation cross-linked polyolefin resin with a thickness of ≥4mm. After folding the flat foam in half with an included angle of 0 to 5°, it is unfolded and restored to a flat shape. After holding for 0 to 300 seconds, no foam is visible to the naked eye. There are crease marks on the cotton folded surface. The invention also discloses its preparation method. First, the raw materials are mixed, then, under the condition of lower than the decomposition temperature of the raw materials, the polyolefin resin mixture is formed into a sheet, and finally, the obtained sheet is irradiated with electron radiation to make the obtained sheet. It is cross-linked, and the cross-linked foamable sheet is placed in a heating furnace for foaming to obtain a foam with a smooth surface and recoverable crease marks. By controlling the amount of co-crosslinking agent and the amount of electron irradiation, the The foam skin layer has a relatively low degree of cross-linking and is smooth, with the properties of recoverable crease marks. |
