Abstract
Изобретение относитс к области производства композиционных материалов на основе древесных частиц и стекловолокна. Изобретение позвол ет снизить давление прессовани до 35-40 МПа (изв. 50), уменьшить врем выдержки в прессе до 40-43 с/мм (изв. 56), повысить текучесть пресс- композиции до 130-139 мм (изв. 93). Предлагаема полимерна пресс-композици включает. мас.%: фенолформаль- дегидна резольна смола 35-39, три- этаноламин 2-5, стекловолокно 35-40, древесные частицы остальное. 2 табл. соThe invention relates to the production of composite materials based on wood particles and fiberglass. The invention makes it possible to reduce the pressing pressure to 35-40 MPa (iz. 50), to reduce the exposure time in the press to 40–43 s / mm (iz. 56), to increase the fluidity of the press composition to 130–139 mm (iz 93.) . The proposed polymer press composition includes. wt.%: phenol-formaldehyde resole resin 35-39, tri-ethanolamine 2-5, fiberglass 35-40, wood particles the rest. 2 tab. with
