Description
Известен способ получени кровельных материалов путем обработки измельченных резиновых отходов в нефт ном битуме при температуре не ниже 170°.A method of obtaining roofing materials is known by treating crushed rubber waste in oil bitumen at a temperature not lower than 170 °.
Недостатком этого способа вл етс необходимость предварительного измельчени резиновых отходов и недостаточно хорошее качество изделий.The disadvantage of this method is the need to pre-crush rubber waste and the product quality is not good enough.
Резинобитум, изготовленный по предложенному спогобу, имеет повышенное качество и технологи его изготовлени прош,е, так как исключена операци измельчени резиновых отходов. Эти отходы раствор ют в зеленом масле при температуре от 170 до 220° и полученный продукт с абсолютной в зкостью не ниже 50 сантипуаз при температуре 50° смешивают с гудроном или битумом и окисл ют воздухом обычным способом при температуре от 190 до 220°. Резинобитум может примен тьс в качестве покровного сло при производстве рубероида.The rubber bitumen produced according to the proposed method has an enhanced quality and is manufactured using the same technology as the grinding of rubber waste is excluded. This waste is dissolved in green oil at a temperature of 170 to 220 ° C and the resulting product with an absolute viscosity of at least 50 centipoise at 50 ° C is mixed with tar or bitumen and oxidized with air in the usual way at a temperature of 190 to 220 °. Rubber bitumen can be used as a coating layer in the production of roofing felt.
Предмет изобретени Subject invention
Способ получени резинобитума путем обработки старых резиновых отходов битумом, отличаюшийс тем, что, с целью упрощени технологического процесса и повышени качества изделий, эти отходы без какого-либо измельчени подвергают растворению в зеленом масле при температуре от 170 до 220°, а полученный при этом продукт, имеюший абсолютную в зкость при температуре 50° не ниже 50 сантипуаз, смешивают с гудроном или битумом и окисл ют воздухом обычным способом при температуре от 190 до 220°.The method of obtaining rubber bitumen by treating old rubber waste with bitumen, characterized in that, in order to simplify the process and improve the quality of products, this waste is dissolved in green oil at a temperature of from 170 to 220 ° C, and the resulting product having an absolute viscosity at a temperature of 50 ° not lower than 50 centipoise, it is mixed with tar or bitumen and oxidized with air in the usual way at a temperature of 190 to 220 °.
