Abstract

Thermoplastic elastomeric compositions exhibiting improved compression set and oil resistance comprise blends of olefin rubber and crystalline polyolefin resin in which the rubber is cured with phenolic curative.

Description

Изобретение относитс  к резиновой промьвпленности, в частности к злас- топластичному составу, из которюго могут быть изготовлены шины, рукава, и шланги, ремни, уплотнени  и прокладки , пресс-издели .The invention relates to rubber production, in particular to a plastic-plastic composition, from which tires, sleeves, and hoses, belts, seals and gaskets, and a press product can be made.

Цель изобретени  - уменьшение остаточного сжати  и повьшгение масло- стойкости резин.The purpose of the invention is to reduce the residual pressure and reduce the oil resistance of the rubber.

Маточную смесь, содержащую ТЭПК (тройной этилен- проп иле новый каучук) , парафиновое масло дл  наполненн ,,- газовую сажу, окись иинка, стеариновую кислоту и противостаритель, в указанных количественных соотношени х (мас.ч.), смешивают с полипропиленом в смесителе Брабендера при 80 об/минThe masterbatch containing TEPK (ternary ethylene-prop silt new rubber), paraffin oil filled with carbon black, oxide of ika, stearic acid and antioxidant, in the indicated proportions (parts by weight), are mixed with polypropylene in the mixer Brabender at 80 rpm

при температуре масл ной баии в течение 2,5 мин, после чего полипропилен плавитс  с получением однородной смеси. Под температурой смесител  Брабендера следует понимать температуру масл ной бани. После этого добавл ют фенольный вулканизатор, продолжа  перемешивать еще 4 мин; за зто врем  достигают максимальной консистенции по Брабендеру. Состав удал ют , испытуемые образцы подвергают пр мому прессованию при . Затем их охлаждают до температуры ниже под давлением перед выгрузкой. Свойства отформованного листового материала замер ют и регистрируют.at an oil baih temperature for 2.5 minutes, after which the polypropylene melts to form a homogeneous mixture. The temperature of the Brabender mixer means the temperature of the oil bath. After that, the phenolic vulcanizer is added, continuing to mix for another 4 minutes; During this time, the maximum consistency according to Brabender is reached. The composition is removed, the test specimens are directly compressed at. They are then cooled to a temperature below the pressure before unloading. The properties of the formed sheet material are measured and recorded.
