A continuous production device and method for a silane-modified sealing material are provided. The device includes a twin screw extruder set, a cooling unit, and a static mixing unit; where the twin screw extruder set includes at least two twin screw extruders in series, each of which is provided with at least two inlets and at least one vacuum port, the cooling unit is disposed between last two stages of the twin screw extruders, and an outlet of a last-stage twin screw extruder is connected to the static mixing unit. Through the arrangement of various units of the device and their positional relations, components can be mixed in sequence or added in stages, so as to adapt to the characteristics of each component; a heat stabilizer and a polymer are added together as raw materials, which can increase the temperature for dehydration and avoid thermal decomposition of the polymer, and they cooperate with a dehydrant to make water in the system easier to remove; and the device has high operation flexibility and can adapt to the requirement of variability of a formulation of the silane-modified sealing material. |
