Description
54) СПОСОБ ПОЛУЧЕНИЯ СТЕКЛОТЕКСТОЛИТА54) METHOD OF OBTAINING GLASS-TEXTOLITE
1one
Изобретение относитс к способу получени стеклотекстолитов на основе стеклоткани и кремнийорганической смолы, используемых при длительной работе при повышенной температуре .This invention relates to a process for the preparation of glass fiber laminates based on glass cloth and silicone resin used for prolonged operation at elevated temperature.
Известен способ получени стеклотекстолита на основе стеклоткани и полиметилфенилсилоксановой смолы, отверждение провод т при . Стеклотекстолит имеет теплостойкость 250-300°С и при этом обладает низкой стабильностью диэлектрических свойств.A known method for producing fiberglass based on glass cloth and polymethylphenylsiloxane resin, curing is carried out at. Glass fiber has a heat resistance of 250-300 ° C and at the same time has a low stability of the dielectric properties.
Целью изобретени вл етс повышение теплостойкости стеклотекстолита .The aim of the invention is to increase the heat resistance of fiberglass.
Данна цель достигаетс тем, что при получении стеклотекстолита стеклоткань пропитывает св зующим на основе полиметилфенилсилоксановой смолы, дополнительно содержащим фосфорнитриланилид , преимущественно в количестве 0,5-5% от веса смолы.This goal is achieved by the fact that upon receipt of a fiberglass plastic fiberglass impregnates with a binder based on polymethylphenylsiloxane resin, which additionally contains phosphonitrimilanilide, mainly in the amount of 0.5-5% by weight of the resin.
Дл осуществлени способа сначала готов т св зующее из 50-60%-ного раствора полиметилфенилсилоксановой, смолы в спирте с добавкой 1,0-5,0% For carrying out the process, a binder is first prepared from a 50-60% solution of polymethylphenylsiloxane resin in alcohol with an additive of 1.0-5.0%

Стеклоткань пропитывают св зующим на пропиточной машине по режиму , обеспечивающему содержание св зующего в стеклоткани 24-26% и летучих , выдел ющихс после выдержки 15 пропитанной стеклоткани при в течение 30 мин - 1,2-2%. Стеклотекстолит и его издели формуют из пропитанной стеклоткани при с выдержкой 10 мин на 1 мм толщины Fiberglass is impregnated with a binder on an impregnating machine according to a mode that provides a binder content in fiberglass of 24-26% and volatile, released after holding 15 of the impregnated glass fiber for 30 minutes - 1.2-2%. Glass fiber laminate and its products are molded from impregnated fiberglass at an exposure time of 10 minutes per 1 mm thickness.

Запрессованный стеклотекстолит или изделие подвергают термообработке в свободном состо нии при 20025 250°С в течение 2-5 ч.The pressed glass fiber laminate or product is heat treated in a free state at 20025 to 250 ° C for 2-5 hours.
Содержание св зующего в стеклотекстолите равн етс 22-25%.The binder content in fiberglass is 22-25%.
Свойства стеклотекстолита при высокой температуре характеризуютс 30 данными таблицы.The high-temperature fiberglass properties are characterized by 30 data tables.
