Modified rubber prepared by oil shale waste slag and method for preparing modified rubber by oil shale waste slag

Abstract

The invention relates to modified rubber prepared by oil shale waste slag and a method for preparing the modified rubber by oil shale waste slag. The method comprises the following steps that oil shale waste slag subject to oil extraction is smashed to be the particle size smaller than 300 mesh, the smashed oil shale waste slag is placed into a high temperature furnace for braking, isolated from the air to conduct the thermal insulation, cooled down with the high temperature furnace and made into carbonized oil shale waste slag, the carbonized oil shale waste slag, raw rubber, carbon black, zinc oxide, powdered sulfur and vulcanization accelerator are added into a mixing roll, are mixed at a certain temperature, and formed in a panel vulcanizing machine after being cooled down. The invention makes the best of the organic matter residual body of residual in oil shale waste slag to change the organic matter residual body into valuable, and eliminates the environmental pollution caused by that oil shale waste slag is stacked in the open air; and the surface of the carbonized oil shale waste slag powder is uniformly carbonized, covered firmly, and good in compatible with the organic matters; the performance is good, the process is simple, and the cost is low. The invention saves the afterbaked energy, and reduces the discharging of carbon dioxide generated in afterbaking. The various indexes of the mechanical property of a test sample reach the GB 3778-94 standard.

Description

Technical field: [0001] The invention relates to the reuse of waste after oil extraction of solid fuel, in particular to ash modified rubber after oil extraction of oil shale and a method thereof. Background technique: [0002] my country is a country rich in oil shale resources. Northeast China, North China, and Northwest provinces are even richer. The proven reserves of Fushun, Maoming, and Huadian mines that have been exploited are more than 6 billion. In addition, Nong'an, Wangqing, Jilin Province , Dongsheng in Inner Mongolia, Xushanling and Yaojie in Gansu, the northern foot of Bogda Mountain in Xinjiang, and Zhan County in Guangdong all have large reserves. From 2004 to 2006, my country conducted the first domestic evaluation of oil shale resources, and found that the amount of geological resources was 719.9 billion tons, equivalent to 47.6 billion tons of shale oil. Oil shale is flake after crushing, its oil content reaches 32.2, its volatile matter is only .22, its ...

Problems solved by technology

[0005] Although these utilizations can digest part of the oil shale ash, the added value of building materials is low. Although the added value of white carbon black is high, some beneficial components are not fully utilized and burned, which increases the amount of carbon dioxide. emissions, resulting in a waste of resources

[0006] Existing oil shale ash is used to produce white carbon black in addition to building materials. No one thought that it can also be used as a filler for modified rubber. The idea of ​​this invention is to overcome people's prejudice and provide a Formulation and method for producing carbon black
