Problems solved by technology

[0005] The silicone rubber composite material is obtained after high temperature vulcanization in a flat vulcanizer; the vulcanization process is 170-190°C, 5-15Mpa, vulcanization 10-15min; the silicone rubber composite material containing carbon nanotubes is obtained; the emulsion blending method can make CNT and other fillers are more uniformly dispersed in the rubber matrix, and acid and other demulsifiers are usually used to realize the co-precipitation of latex particles and CNT, but the addition of acid or other chemical reagents for flocculation and subsequent dehydration and drying process will easily cause the filler to reunite, resulting in low efficiency. , time-consuming and large water consumption; at the same time, mechanical blending method, solution blending method and melt blending method also have some inevitable defects in the prepared rubber composites due to process problems

Abstract

The invention discloses a preparation method of a CNT-SiO2 / CI material. The preparation method comprises the following steps: S100, mixed liquid of silicon dioxide and deionized water is dispersed into silicon dioxide aqueous dispersion through a high-speed shearing machine, and then ground through a grinding machine; S200, obtained silicon dioxide slurry is stirred and mixed with a CNT water solution with the appropriate proportion, and a centrifuged and concentrated neoprene latex is added to be mixed and stirred; S300, CNT-SiO2 / CIL mixed liquid is sprayed onto a roller of a high-temperatureopen mill, and an adhesive layer is formed ; S400, the adhesive layer is scraped down for standby application; and S500, masterbatch is plastified and subjected to banburying on the open mill. A grinding device comprises a base and a mounting groove formed in the base; a planet wheel is arranged in the mounting groove, and a fixing support is arranged on a star wheel of the planet wheel; and thefixing support is provided with a grinding tank through a movable hinge device, a pressing rod device is mounted on the grinding tank, a shunt disc is arranged on the upper part of the grinding tank,is connected into the mounting groove, and comprises an inner wheel disc and an outer rail ring, thus grinding is sufficient, and the grinding confusion degree of the slurry is increased.

Description

technical field [0001] The invention relates to the field of rubber mixing methods, specifically a CNT-SiO 2 / CI material preparation method and grinding 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] Neoprene latex is quite special among many synthetic latexes. In terms of elasticity, tensile strength and elongation strength, neoprene latex is similar to natural rubber. At the same time, neoprene latex is resistant to solvents and chemicals. It has excellent performance in terms of oil resistance and grease resistance. Other latexes are not as good as neoprene latex in terms of aging characteristics, and ...
