Description

Предлагаемое изобретение относитс  к области создани  новых пластических масс, обладающих высокой водостойкостью, стойкостью к действию кислот и стабильных при повышенных температурах.The present invention relates to the field of creating new plastics with high water resistance, acid resistance and stable at elevated temperatures.

Компонентами новых пластических масс  вл ютс  комплексные кoндe сациопно-полимеризационпые продукты па основе поволачных смол, поливинилхлорида и гексаметиле)тетрамипа с введением наполнителей .The components of the new plastics are complex sasiopno-polymerization products based on woven resins, polyvinyl chloride and hexamethyl) tetramp with the introduction of fillers.

Способ отличаетс  от ранее предложенных тем, что новолачна  смола химически совмеш,аетс  с полихлорвиниловой смолой в присутствии гексаметилептетрамина, который при нагревании па вальцах или в прессформе распадаетс  с образованием , повидимому, диметиленимипных групп, св зываЕОщих цепи новолачной смолы и поливинилхлорида .The method differs from the previously proposed ones in that the Novolac resin chemically combines with the PVC resin in the presence of hexamethylaptetramine, which, when heated in the rolls or in the mold, decomposes to form, apparently, dimethyleneie groups bound to the Novolac resin and in the mold, and they are attached to the polyvinyl chloride resin and the polyvinyl chloride resin forms attached to the chain of the Novolac resin material and the polyvinyl resin, and apparently, dimethylenimide groups bound to the Novolac resin and the polyvinyl crystals and apparently formed in the form of dimethylenimide groups bound to the Novolac resin and the polyvinyl crystals, apparently, connected to the polymer chains of the Novolac resin and the polyvinyl crystals, apparently, dimethylenium groups bound to the Novolac resin and in the mold, and they are attached to the polyvinyl chloride resin and polyvinyl chloride resin.

Изготовление пресспорошков осушествл етс  путем смешени  компонентов в шаровой мельнице. Полученна  однородна  масса подвергаетс  гор чему вальцеванию с последующим измельчением на дробильных агрегатах.The fabrication of press powders is carried out by mixing the components in a ball mill. The resulting homogeneous mass is subjected to hot rolling, followed by grinding in crushers.

Пресскомпозиции пригодны дл  изготовлени  изделий обычными способами.Press presses are suitable for the manufacture of products using conventional methods.

Нар ду с минеральными наполнител ми дл  изготовлепи  композиций примен етс  древесна  мука, пропитанна  фенолоспиртами или водоспирторастворимыми фенольио-формальдегидными смолами.Along with mineral fillers, wood flour impregnated with phenol-alcohols or water-alcohol-soluble phenolio-formaldehyde resins is used to make compositions.

Пример. 30-45 вес. частей новолачной смолы смешивают в шаровой мельнице с 20-35 вес. част ми поливинилхлорида и гексаметилентетрамином , 30-45 вес. част ми каолина, кварцевой муки или графита , 10-20 вес. част ми обработанной фенолоспиртами или фенольноформальдегидными смолами древесной муки в присутствии стабилизаторов поливинилхлорида, смазывающих вегцеств и красителей.Example. 30-45 weight. parts of Novolac resin are mixed in a ball mill with 20-35 weight. parts of polyvinyl chloride and hexamethylenetetramine, 30-45 wt. parts of kaolin, quartz flour or graphite, 10-20 wt. parts treated with phenolic alcohols or phenol-formaldehyde resins of wood flour in the presence of polyvinyl chloride stabilizers, lubricating vegetations and dyes.

Прессовочный материал на основе указанной композиции кислотостоек: привес материала после выдержки в серной кислоте ул,. веса 1,32 при температуре 65° в течепие 48 часов составл ет 0,2-0,5 %.Pressing material on the basis of the specified composition is acid resistant: the weight gain of the material after exposure to sulfuric acid st. the weight of 1.32 at a temperature of 65 ° during 48 hours is 0.2-0.5%.

Материал имеет следующие физико-механические свойства:The material has the following physical and mechanical properties:
