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

Abstract

The invention discloses a CNT / IIR composite material preparation method. The CNT / IIR composite material preparation method comprises following steps: 1, a CNT / IIR mixed solution is prepared, and is mixed and stirred for further processing; 2, the gas phase assisted jet fogging gun is adopted for spraying of the CNT / IIR mixed solution onto a roller of a high temperature open mill, after evaporationof water of the CNT / IIR mixed solution on the high temperature open mill, a masterbatch formed on the roller is collected through scraping; 3, 111 phr masterbatch, zinc oxide ZnO, stearic acid SAD, sulfur, super accelerator TMTD, DM accelerator, RD anti-aging agent and anti-aging agent 4020 are introduced into the open mill successively for mixing, and masterbatch plastifying and banburying to obtain a GO-IIR composite material. The jet fogging gun comprises an assembly housing support, and a material preparation cylinder, a pneumatic pump, and flow deflectors which are arranged on the assembly housing support; a micro move assembly is arranged on the internal side of the assembly housing support, and is provided with fogging nozzles; and an air curtain groove is arranged at the connection part of each flow deflector and the assembly housing support. The technology is simple and controllable; principles are scientific and reasonable; fogging uniformity is ensured; and generation of secondary drop attachment caused by water vapor adhesion is avoided.

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 ...
