Embodiment 1
[0030] This embodiment provides a production method of oleophilic linoleum base cloth, the production method comprises: polyester chips are transported to the silo, crystallized and dried, screw extruded, melt filtered, spinning, cooling, drafting, pendulum Wire laying, needle punching reinforcement, hot rolling and chemical glue impregnation drying and winding packaging; wherein, based on the total weight of the glue solution, the glue solution used for the chemical glue impregnation and drying includes: acrylate 6wt% , water 93wt% and curing agent 1wt%; Specifically as follows:
[0031] Using polyester chips as raw material, the undried amorphous polyester chips are sent to the high-level silo by the air pulse conveying device, and fed into the crystallization and dryer through the rotary valve; the crystallization temperature is controlled at 165°C, and the drying temperature is 170°C; after crystallization and drying, the moisture content of the slices is controlled to a c...
Embodiment 2
[0033] The difference between this embodiment and Example 1 is: based on the total weight of the glue solution, the glue solution used for dipping and drying the chemical glue includes: acrylate 7.5wt%, water 91.5wt% and 1wt%; other processes and Parameters are all the same as in Example 1.
Embodiment 3
[0035] The difference between this embodiment and Example 1 is: based on the total weight of the glue solution, the glue solution used for dipping and drying the chemical glue includes: acrylate 8wt%, water 91wt% and 1wt%; Same as Example 1.
