Definitions
- the present invention relates to a production apparatus and production method for a microporous polyolefin resin sheet.
- the resin melted by the application of heat and shearing force by the extruder 1 is discharged by a certain amount by the gear pump 2, and then passes through the filter 3 to filter out foreign substances and the like, and passes through any lip gap. It is discharged and formed into a sheet form from the cap 4 having it.
- the discharged sheet-like molten resin is cooled and solidified by the cooling and solidifying device 5.
- the cooled and solidified sheet 6 is subsequently stretched in an arbitrary direction and magnification by a stretching device 7 and wound up by a winder 8.
- the thickness of the sheet in the width direction is measured by the thickness meter 9, and the lip gap of the base 4 is adjusted by the thickness controller based on the thickness measurement data, so that a sheet having a uniform thickness in the width direction can be obtained.
- the low molecular weight component, diluent, and additive gas in the polymer are released into the atmosphere around the decompression chamber, and the pressure is reduced. It will be sucked into the chamber.
- the low molecular weight component, diluent, and additive gas in the polymer sucked into the vacuum chamber are further cooled in the vacuum chamber and liquefied in the vacuum chamber. When a certain amount of liquid accumulates, it drops to the cooling and solidifying device, contaminates the cooling and solidifying device to which the sheet adheres, and leads to sheet defects.
- Patent Document 2 As a method for preventing the droplets from dropping from the rectifying plate arranged in the decompression chamber, for example, by heating the rectifying plate in the decompression chamber to the condensation point or more, low molecular weight components in the polymer or dilution And a method for preventing liquefaction of the additive and additive (Patent Document 1).
- Patent Document 2 there is a method (Patent Document 2) in which a pipe having an opening is installed in the vicinity of the gas generation point and the gas generated from the sheet is forcibly removed by suction (Patent Document 2), which shows that a resin sheet can be manufactured stably. ing.
- the pressure of air at the sheet landing point to the cooling and solidifying device increases, so the suction pressure by the decompression chamber must be reduced with respect to the atmospheric pressure. is there.
- the amount of air sucked in the decompression chamber is increased, and the gas concentration of the volatile components on the back side of the sheet, that is, the surface side in the vicinity of the surface where the sheet contacts the cooling and solidifying device is lowered to maintain the gas concentration balance.
- the amount of gas generated from the polymer low molecular weight components, diluents, and additives is further increased.
- the object of the present invention is to reduce the low molecular weight component of the polymer when the low molecular weight component, diluent, or additive gas vaporized around the sheet and the vacuum chamber is sucked into the vacuum chamber and liquefied in the vacuum chamber.
- An object of the present invention is to provide a polyolefin resin sheet production apparatus and production method capable of preventing dripping onto a cooling and solidifying device by forcibly removing a liquefied product of a diluent and an additive and capable of stably forming a film at high speed.
- the apparatus for producing a microporous polyolefin resin sheet of the present invention that solves the above problems is a base for discharging a resin in which a polyolefin resin and a diluent are mixed into a sheet, and while conveying a sheet discharged from the base
- a cooling and solidifying device for cooling and a decompression chamber that is installed on the upstream side of the base in the sheet conveying direction and sucks air between the sheet discharged from the base and the cooling and solidifying device.
- the decompression chamber has an opening facing the space between the base and the cooling and solidifying device.
- a current plate is provided in the decompression chamber in the seat width direction in the vicinity of the opening.
- the current plate is hollow inside, and a plurality of openings connected to the inside are formed on the surface.
- the method for producing a microporous polyolefin resin sheet of the present invention uses the apparatus for producing a microporous polyolefin resin sheet of the present invention to suction and rectify the inside of the decompression chamber and the inside of the current plate. While keeping the pressure inside the plate lower than the pressure inside the decompression chamber, the polyolefin resin discharged in a sheet form from the die is conveyed while being cooled by a cooling and solidifying device.
- the “width direction” is a direction perpendicular to the sheet conveyance direction.
- “Below the current plate” means a direction from the current plate toward the surface of the cooling and solidifying device closest to the current plate.
