Abstract

The invention relates to a rubber filler, which comprises the following components: 20-70 wt% of a modified solid; 15 wt%-60 wt% of carbon black; 3 wt%-6 wt% of a vulcanizing agent; 5 wt%-20 wt% of an activator; 1 wt%-7 wt% of a vulcanization accelerator; and 1 wt%-7 wt% of an anti-aging agent; wherein the modified solid with certain water content and oil content is obtained by taking oil sludge sand as a raw material, firstly separating coarse sand with the particle size of more than 100 microns, and then dehydrating and deoiling. According to the invention, resource reutilization of solid waste is realized, the added modified solid has a prominent effect on performance improvement of rubber, and a soil-in-oil structure is formed by controlling proper oil content in the modified solid, so that the modified solid can be easily filled, embedded and extruded into gaps of a mixture, the interaction force between the mixture is enhanced, and therefore, the mixture is tighter, and the material strength of the rubber filler is improved.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a rubber filler, in particular to a rubber filler containing a modifier prepared from oil sludge sand. Background technique [0002] Rubber includes natural rubber and synthetic rubber. Natural rubber is a kind of non-polar rubber, which has high elasticity at room temperature, excellent physical and mechanical properties, small hysteresis loss, good bending resistance, and good electrical insulation properties. Synthetic rubber is rubber developed by chemical methods. Its production is not restricted by region. It can be mass-produced in a short period of time. The consistency of rubber products is good. However, research shows that only some of its properties are better than natural rubber. Comprehensive The performance is far inferior to natural rubber. Natural rubber remains by far the best general purpose rubber. [0003] The main component of natural rubber is polyisopren...
