Abstract

The invention discloses a GR-SiO2/IIR material preparation method. The method comprises the following steps that S100, sodium silicate, deionized water, absolute ethyl alcohol and a surfactant are mixed, and stirred under water bath heating to form a modified sodium silicate aqueous solution; S200, a proper amount of lauric acid and hydrochloric acid are added into the modified sodium silicate aqueous solution, and ultrasonic treatment is carried out for half an hour under an ice-water bath to obtain a silica precipitation solution; S300, the silica precipitation solution is filtered and flushed to obtain a modified silica solid-liquid mixture, the modified silica solid-liquid mixture is placed in a beaker, a proper amount of deionized water is added, and the pH value is adjusted to be neutral; S400, deionized water is added, a GR aqueous solution is added after stirring, centrifugally concentrated butyl latex is added into GR-SiO2 mixed liquor, and GR-SiO2/IIRL mixed liquor is obtained; S500, the GR-SiO2/IIRL mixed liquor is heated and poured into a container tank to be ejected to a roller of a high temperature open mill and dried to form rubber master batch; and S600, the rubbermaster batch is placed into the open mill, filler is sequentially added for mixing, and preparation of a GR-SiO2/IIR composite material is completed. The technology is simple, and the process is controllable.

Description

technical field [0001] The invention relates to the field of rubber mixing, specifically a GR-SiO 2 / IIR material preparation method and glue spraying device. Background technique [0002] Mixing is the first step in the rubber processing process, and it is also the most critical process. Through this process, various fillers are fully mixed with rubber, and the fillers are dispersed as uniformly as possible. The quality of the mixing result directly determines the rubber product. The performance and service life have been widely concerned by the industry. [0003] Graphene (GR) is a material in the carbon family. It is a two-dimensional nanomaterial with a carbon atom hybridization type of sp2 carbon structure and a single-layer structure obtained after graphite processing. GR has ultra-thin sheets. Structure, huge specific surface area, its internal structure is a honeycomb layered structure, with excellent mechanical, thermal, mechanical and electrical properties, so th...
