a kind of gr-sio 2 /ci material preparation method and atomization gel forming device

Abstract

The invention discloses a GR-SiO2 / CI composite material preparation method. The method comprises the following steps: S100, mixing sodium silicate, deionized water, absolute ethyl alcohol and a surfactant based on ratio; and heating and stirring in water bath to obtain a modified sodium silicate water solution; S200, adding lauric acid and hydrochloric acid to the modified sodium silicate water solution; reacting; and filtering to obtain a modified silicon dioxide solid-liquid mixture; S300, mixing the modified silicon dioxide solid-liquid mixture and deionized water; stirring at a high speed;then adding 3 parts by mass of GR water solution; adding centrifugally-concentrated neoprene latex to a GR-SiO2 mixed solution to obtain a GR-SiO2 / CIL mixed solution; S400, heating, evaporating and drying the GR-SiO2 / CIL mixed solution to obtain a rubber master batch; and S500, feeding the rubber master batch into a mixer; sequentially adding fillers; and mixing to obtain the a GR-SiO2 / CI composite material. The method is simple and controllable in processes, scientific and reasonable in theory, low in energy consumption and production cost, high in operability, uniform in dispersity, few inagglomeration problems, environmentally friendly, high in performances of the prepared composite material, and high in economic value.

Description

technical field [0001] The invention relates to the field of rubber mixing, specifically a GR-SiO 2 / CI material preparation method and atomization glue forming 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 oxide (GO) is a derivative of graphene, and is a two-dimensional material obtained after graphite is oxidized and has a carbon atom hybridization type of sp2 carbon structure in the original graphite structure. GO has an ultra-thin sheet structure and a large specific surface area. Its surface contains a large number of oxygen-containing groups such as hydroxyl and carboxyl, and has excellent ...

Problems solved by technology

[0004] Traditional tires have always been difficult to coordinate the relationship between rolling resistance, wet skid resistance and wear resistance. SiO 2 As a reinforcing filler that does not depend on petroleum resources, its reinforcing effect on rubber is close to that of carbon black, which can improve this problem very well, but SiO 2 There are a lot of hydroxyl groups on the surface, the compatibility with rubber is not good, SiO 2 The interaction with rubber is weak, and when it is filled into rubber, the wear resistance will decrease obviously;

[0005] The emulsion blending method can disperse GO and other fillers in the rubber matrix more uniformly. Usually, acid and other demulsifiers are used to realize the co-precipitation of latex particles and GO. Reunited again, causing problems of low efficiency, long time consumption and high water consumption
