Description

Изобретение относитс  к технологическим средствам производства изделий из полимерных материалов методом лить  и предназначено дл  использовани  в качестве разделительного сло  дл  пресс-форм и арматуры при заливке, например, узлОв, блоков радиоэлектронной аппаратуры, изготовлении деталей из полиуретановых, эпоксидных , эпоксиднофенольных пенопластов, компаундов, не содержащих аминов.The invention relates to technological means of manufacturing products from polymeric materials by the method of casting and is intended for use as a separating layer for molds and reinforcement when pouring, for example, nodes, blocks of radioelectronic equipment, manufacturing parts from polyurethane, epoxy, epoxyphenolic foams, compounds, not containing amines.

Цель изобретени  - снижение огнеопасности состава при сохранении его однородности .The purpose of the invention is to reduce the flammability of the composition while maintaining its uniformity.

Состав готов т следующим образом.The composition is prepared as follows.

Фторкаучук (СКФ-26 или СКФ-32) измельчают и смешивают с диметилкетоном, в котором растворен полиметилфенилсилоксан (ПМФС-4).. Полученную смесь дл  набухани  фторкаучука выдерживают 2-3 ч в герметично закрытой емкости, к этому составу добавл ют трифтортрихлорэтан (фреон 113) и периодически взбалтывают в течение 24 ч.Fluororubber (SKF-26 or SKF-32) is crushed and mixed with dimethyl ketone in which polymethylphenylsiloxane (PMFS-4) is dissolved .. The mixture obtained for swelling of fluororubber is kept for 2-3 hours in a hermetically sealed container, trifluorochlorochloroethane (freon 113) and periodically shaken for 24 hours.

Получают однородный раствор в зкостью 12-14 с по вискозиметру ВЗ-4 при 20°С. Смазку нанос т на металлическую форму кистью, погружением или другим мето- дом и сушат в течение 10 мин (не менее) при комнатной температуре. Затем заполн ют форму заливочным материалом, после отверждени  которого форму охлаждают, разбирают и извлекают готовое изделие.A homogeneous solution is obtained with a viscosity of 12–14 s using an OT-4 viscometer at 20 ° C. The lubricant is applied to the metal mold with a brush, dipping or other method and dried for 10 minutes (at least) at room temperature. The mold is then filled with potting material, after which the mold is cured, the mold is cooled, taken apart and the finished product is removed.

Содержание компонентов в составах приведено в таблице.The content of components in the compositions shown in the table.

Составы 1-4 однородны и не гор т. В составах 5-7 фторкаучук не раствор етс . В составах 8-12 в растворе образуютс Compounds 1-4 are homogeneous and not hot. In compositions 5-7, fluororubber does not dissolve. In formulations 8-12 in solution are formed

хлопь . Составы 13,14 и известный однородны , но легко воспламен ютс . В составе 15 фторкаучук не раствор етс .flake Compounds 13, 14 and known are uniform, but easily flammable. In composition 15, fluororubber does not dissolve.

Как следует из данных таблицы, предлагаемый состав позвол ет получить негорючую смазку при сохранении однородности раствора.As follows from the data in the table, the proposed composition allows a non-flammable lubricant to be obtained while maintaining the homogeneity of the solution.
