Description

Известен способ получени  пластмасс на основе полнсилоксановой смолы, неорганических волокнистых и порошкообразных наполнителей и полиалюмосилоксановых отвердителей.A known method for producing plastics based on full-siloxane resin, inorganic fibrous and powdered fillers, and polyaluminosiloxane hardeners.

Предлагаемый способ получени  пластмасс также на основе полисилоксановой смолы в отличие от известного позвол ет расширить ассортимент отвердителей, с этой целью в качестве отвердителе при.1сн ют полкалюмофенилсилоксан и (или) нолиалюмонафтепатфенилсилоксан.The proposed method for the production of plastics also based on polysiloxane resin, in contrast to the known, allows the range of hardeners to be expanded, for this purpose polycallumophenyl siloxane and / or poly aluminum reflux phenyl siloxane are taken as hardener.

При введении указанных отвердителей, а также нх смеси в полиметилсилоксан (К-71) получают термореактивиую смолу с нужным временем отверждени . Скорссть процесса отверждени  зависит от соотношени  в композиции полиметилсилоксана (К-71) и полиалюмонафтенатфенилсилоксана и (или) полиалюмофенилсилоксана.With the introduction of these hardeners, as well as their mixtures in polymethylsiloxane (K-71), a thermo-reactive resin is obtained with the desired curing time. The rate of the curing process depends on the ratio in the composition of polymethylsiloxane (K-71) and polyalumonaphthenate-phenylsiloxane and (or) polyaluminophenylsiloxane.

Дл  практических целей примен ют от 80 до 95% полиметилсилоксана (К-71) и от 5 до 20% вышеуказанных отвердитслей. Оптимальным  вл етс  10% отвердителей по отношению к нолиметилсилоксану. Лучшие результаты получают при применении 5% полиалюмонафтснатфеннлсилоксана , 5% полиалюмофенилсилоксана и 90% полиметилсилоксана (К-71). Так, например, продолжительность отверждени  лаковой пленки полиметилсилоксана (К-71) на медной пластинке при температуре 200° составл ет 50 лш,н; после введени  в полиметилсилоксан 5% нолиалюмонафтенатфенилсилоксана и 5% полиалюмофенилсилоксака врем  отверждени  лаковой пленки при тех же услови х сокрашаетс  до 4 .пин. Предлагаемые отвердители повышают также термическую стабильность полиметилсилоксана и пластических масс на его основе . Полиалюмофенилсилоксан и (или) полиалюмонафтенатфенилсилоксан способствуют снижению хрупкости и предупреждают образование треш;ип во врем  прессовани  подобных пластмасс,  вл ютс  нетоксичными, не вызывают коррозии металлов и не снижают электроизол ционных свойств получаемых пластмасс. For practical purposes, from 80 to 95% of polymethylsiloxane (K-71) and from 5 to 20% of the above-mentioned hardeners are used. The optimum is 10% of hardeners with respect to nolimethylsiloxane. The best results are obtained with the use of 5% polyalumonaftsnathenylsiloxane, 5% polyaluminophenylsiloxane and 90% polymethylsiloxane (K-71). For example, the curing time of a polymethylsiloxane lacquer film (K-71) on a copper plate at a temperature of 200 ° is 50 lsh, n; After the introduction of 5% niyalyumonaphenate phenylsiloxane and 5% polyaluminophenylsiloxac into polymethylsiloxane, the curing time of the lacquer film under the same conditions is shortened to 4. pin. The proposed hardeners also increase the thermal stability of polymethylsiloxane and plastics based on it. Polyaluminophenylsiloxane and (or) polyalumonaphthenate phenylsiloxane help reduce brittleness and prevent the formation of trash; sp during compression of these plastics are non-toxic, do not cause corrosion of metals, and do not reduce the electrical insulation properties of the resulting plastics.
