Preparation process and production equipment of fluorine-containing rubber for automobile rubber pipe

Abstract

The invention relates to a preparation process and production equipment of a fluorine-containing rubber for an automobile rubber pipe. The production equipment comprises a kettle body with a reaction inner cavity, a feeding pipe and a discharging pipe which are communicated with the reaction inner cavity, and a vacuum air extractor arranged outside the kettle body, wherein the input end of the vacuum air extractor is communicated with the reaction inner cavity through a vacuum air extraction pipeline with a first one-way valve, one end, far away from the kettle body, of the feeding pipe is communicated with a feeding system used for quantitatively adding materials into the reaction inner cavity, and a stirring assembly used for rapidly dispersing the materials entering the reaction inner cavity through the feeding system is arranged in the reaction inner cavity. According to the invention, in daily use, the materials are output from the feeding system and enter the reaction inner cavity through the feeding pipe, and the materials entering the reaction inner cavity are simultaneously stirred in multiple directions through the stirring assembly, so that the materials entering the reaction inner cavity are quickly and uniformly mixed, the material adding precision and the material mixing speed are improved, and the material proportioning precision and the material reaction speed are ensured.

Description

technical field [0001] The invention relates to the technical field of auto parts preparation, in particular to a preparation process and production equipment of fluorine-containing rubber for automobile rubber hoses. Background technique [0002] Fluorine-containing rubber is currently the first choice for the automotive industry. Especially in recent years, with the emergence of new environmentally friendly energy sources and fuels, more stringent requirements have been put forward for fluorine rubber, and the requirements for certain aspects of products for different purposes have become more detailed. Through the research on the vulcanization mechanism of fluororubber, we know that the lower the molecular weight of ordinary fluororubber, the worse the vulcanization performance, but the better the scorch resistance, the higher the molecular weight, the better the vulcanization performance, but the worse the scorch resistance. We are extruding It is required that this type...

AI Technical Summary

Problems solved by technology

The fluorine content of this type of fluororubber is generally about 67%, and its oil resistance and solvent resistance are relatively poor, and the processing equipment used to prepare fluororubber is usually not available or has a simple structure of the stirring assembly (5). The mixing effect between various materials is not good, resulting in slow mixing speed of materials, slow reaction speed of materials, low production efficiency, and usually does not have a feeding system with quantitative feeding function, it is difficult for workers to accurately add the amount of materials control, it is necessary to make improvements
