Abstract
Description
Изобретение относится к резинотехнической промышленности, а именно к конвейерным лентам, используемым для транспортирования грузов с высокой температурой, включая куски красного каления.The invention relates to the rubber industry, namely to conveyor belts used for transporting goods with high temperature, including pieces of red heat.
Известны конвейерные ленты, включающие резинотканевый каркас и наружные обкладки из резин, содержащих бутадиен-стирольный, изопреновый, хлорбутиловый, бутиловый, этиленпропиленовый и фтор-каучуки. Недостатком таких конвейерных лент является относительно невысокая теплостойкость и жаростойкость.Known conveyor belts, including rubber-fabric frame and the outer lining of rubbers containing styrene butadiene, isoprene, chlorobutyl, butyl, ethylene propylene and fluorine rubbers. The disadvantage of such conveyor belts is the relatively low heat resistance and heat resistance.
Наиболее близкой по технической сущности и достигаемому эффекту является конвейерная лента на основе этиленпропилендиенового каучука и бутилкаучука (Патент RU 2116231). Однако данная лента обладает недостаточной жаростойкостью.The closest in technical essence and the achieved effect is a conveyor belt based on ethylene propylene diene rubber and butyl rubber (Patent RU 2116231). However, this tape has insufficient heat resistance.
Цель изобретения - улучшение теплостойкости и жаростойкости обкладочной резиновой смеси и повышение ее рабочего ресурса путем уменьшения деструкции под действием высоких температур (выше 250°С) и повышение сопротивления прожигу от кусков красного каления (температура 800°С).The purpose of the invention is to improve the heat resistance and heat resistance of the lining rubber mixture and increase its working life by reducing destruction under the influence of high temperatures (above 250 ° C) and increasing the resistance to burning from pieces of red heat (temperature 800 ° C).
Указанная цель достигается тем, что рабочая резиновая обкладка в теплостойкой конвейерной ленте выполнена на основе смеси каучуков полиолефиновой группы в соотношении от 60:40 до 90:10 мас.ч.: этиленпропилендиена (с соотношением звеньев этилена к пропилену от 60:40 до 70:30) и 5-30 мас.ч. этиленоктена, с применением перекисной вулканизации на основе 1-6 мас.ч. на 100 мас.ч. каучука пероксидного вулканизующего агента из смеси мета- и параизомеров пероксида.This goal is achieved by the fact that the working rubber lining in a heat-resistant conveyor belt is made on the basis of a mixture of rubbers of a polyolefin group in a ratio of 60:40 to 90:10 parts by weight: ethylene propylene diene (with a ratio of ethylene to propylene units of 60:40 to 70: 30) and 5-30 parts by weight ethylene octene, using peroxide vulcanization based on 1-6 parts by weight per 100 parts by weight rubber peroxide vulcanizing agent from a mixture of meta- and paraisomers of peroxide.
Изготавливаемые в настоящее время конвейерные ленты типа Т3 имеют недостаточный срок эксплуатации - разрушение ленты происходит именно от воздействия высокотемпературного фактора (воздействие высоких температур). Характер разрушений - от растрескивания поверхности до выкрашивания обкладочных резиновых смесей. Один из основных путей улучшения эксплуатационных характеристик - увеличение теплостойкости обкладок. В настоящее время обкладочная резиновая смесь подвергается серной вулканизации, которая не дает требуемых факторов теплостойкости ввиду образования слабых поперечных связей. Пероксидная вулканизация на основе ди-(третбутилпероксиизопропил)бензола позволяет улучшить сопротивление тепловому старению, что ведет к увеличению срока эксплуатации теплостойкой конвейерной ленты. Пероксиды образуют прочные углерод-углеродные поперечные связи, что позволяет производителю конечных изделий лучше использовать полный технический потенциал эластомера.Currently produced conveyor belts of type T3 have an insufficient service life - the destruction of the belt occurs precisely from the influence of the high-temperature factor (the effect of high temperatures). The nature of the damage - from cracking the surface to chipping of the lining rubber compounds. One of the main ways to improve performance is to increase the heat resistance of the plates. Currently, the lining rubber mixture is subjected to sulfuric vulcanization, which does not provide the required heat resistance factors due to the formation of weak cross-links. Peroxide vulcanization based on di- (tert-butylperoxyisopropyl) benzene can improve the resistance to thermal aging, which leads to an increase in the life of the heat-resistant conveyor belt. Peroxides form strong carbon-carbon cross-bonds, which allows the manufacturer of the final products to better use the full technical potential of the elastomer.
Смесь каучуков этиленпропилендиена и этиленоктена обладает великолепной термической стабильностью.The mixture of ethylene propylene diene and ethylene octene rubbers has excellent thermal stability.
