A kind of preparation method of cnt/iir composite material and jet atomization gun for preparation thereof

Abstract

The invention discloses a method for preparing a CNT / IIR composite material, comprising the following steps: S100, obtaining a CNT / IIRL mixed liquid, and mixing and stirring it for standby; S200, spraying the CNT / IIRL mixed liquid to a high temperature through a gas-phase assisted spray atomizing gun On the roller of the open mill, when the water of the mixed solution on the roller evaporates, the masterbatch formed on the roller is scraped off and collected for later use; S300, add 111phr masterbatch, zinc oxide ZnO, hard Fatty acid SAD, sulfur, super-accelerator TMTD, DM accelerator, RD anti-aging agent, anti-aging agent 4020 for mixing, plasticizing and banburying of the masterbatch, and completing the preparation of GO / IIR composite materials, and atomization devices, including Assembling the frame, as well as the batching bottle, air pump and deflector set on the assembly frame, the inside of the assembly frame is provided with a micro-motion component, the micro-motion component is provided with an atomizing nozzle, and the deflector is connected to the assembly frame There is an air curtain groove at the center, the process is simple and controllable, and the principle is scientific and reasonable, which ensures uniform atomization and avoids secondary dripping due to the adhesion of water vapor.

Description

technical field [0001] The invention relates to the field of rubber mixing, in particular to a preparation method of a CNT / IIR composite material and a spray atomizing gun for preparation thereof. 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] At present, the preparation methods of CNT / rubber composite materials mainly include traditional methods such as mechanical blending, solution blending, melt blending and emulsion blending. A polymethylphenylsiloxane disclosed in Chinese patent 201510770421.7 Alkane-carbon nanotube-silicone rubber composite material, carry out according to the following steps: [0004] Step ...

AI Technical Summary

Problems solved by technology

[0009] The emulsion blending method can disperse fillers such as CNTs in the rubber matrix more uniformly. Usually, acid and other demulsifiers are used to realize the co-precipitation of latex particles and CNTs. Agglomeration again, causing problems of low efficiency, long time consumption and large water consumption; at the same time, mechanical blending method, solution blending method and melt blending method also have some unavoidable defects in the prepared rubber composite materials due to process problems
