METHOD OF HONEYCOMB FILLER PRODUCTION Russian patent published in 2008 - IPC B32B3/12 C08J5/24 B32B17/04 

FIELD: technological processes.

SUBSTANCE: glue strips are applied with preset pitch onto glass tissue cloth in longitudinal direction, then they are dried, and glass tissue with applied glue strips is cut into preforms in direction that is perpendicular to glue strips, honeycomb packet is assembled from prepared preforms by laying with displacement of every preform in respect to glue strips that are adjacent by half of pitch, preforms of honeycomb packet are glued at preset temperature and pressure, and honeycomb unit is produced by means of honeycomb packet extension, then prepared extended honeycomb unit is soaked with polymer binder, it is hardened in accordance with preset mode, at that as glass tissue thin glass tissue is used on the basis of fibres made of alumina-borosilicate alkali-free glass of "А-5Пx90" or "А-4Пx90" type, for glue strips phenol-polyvinyl-acetal glue is used of BF-2 type with viscosity of 45 by viscosity gage VZ-246, gluing of honeycomb packet preforms is carried out under vacuum of 0.12-0.16 kgf/cm² according to temperature-time mode: heating up to temperature of 80°C with further pause of 30 minutes, heating up to temperature of 150°C with further pause of 60 minutes, heating up to temperature of 170°C with further pause of 120 minutes, as polymer binder for soaking, bakelite lacquer is used of LBS-1 brand with viscosity of 15 by viscosity gage VZ-246, hardening of honeycomb unit soaked with polymer binder is carried out in accordance with the following mode: heating up to temperature of 100°C with further pause of 30 minutes, heating up to temperature of 150°C with further pause of 90 minutes, heating up to temperature of 170°C with further pause of 120 minutes.

EFFECT: provision of honeycomb filler compression strength; expansion of assortment of manufactured honeycomb filler and increase of manufacturability.
