Title:
CONTINUOUS PRODUCTION DEVICE AND METHOD FOR SILANE-MODIFIED SEALING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2020/258788
Kind Code:
A1
Abstract:
Disclosed are a continuous production device and method for a silane-modified sealing material. The device comprises a twin-screw extruder set, a cooling unit and a static mixing unit, wherein the twin-screw extruder set comprises at least two twin-screw extruders connected in series, each of the twin-screw extruders is provided with at least two inlets and at least one vacuum port, the cooling unit is arranged between the last two stages of twin-screw extruders, and an outlet of the last stage of twin-screw extruders is connected to the static mixing unit. According to the present application, by means of the arrangement of the various units of the device and a positional relationship thereof, different components can be mixed successively or added in stages in order to adapt to the characteristics of different components; by adding a heat stabilizer and a polymer raw material together, the dehydration temperature can be increased, and the thermal decomposition of a polymer can be prevented; by means of the combined action of same with a water removal agent, the moisture in a system is more easily removed; and the device has a large elastic operation space and can adapt to a formula variability requirement of the silane-modified sealing material.
