Problems solved by technology

However, organic oils are less effective in terms of heat resistance, lubricity, and anti-sticking isolation, so the scope of use is very narrow; silicone oils are superior to organic oils in heat resistance and lubricity, and are used in carbon fiber production. The oil used is usually used in the form of emulsion or water dispersion, but polydimethylsiloxane as the main component of the oil is insoluble in water, it is difficult to make a very stable water emulsion, so it is the original silk The production and application of oil agents have caused great technical obstacles

Abstract

The invention relates to a production method of proto-filament oiling agent in carbon fiber production process, which is characterized in that: the method comprises the following steps: a non-ionic surface active agent formulated matter is used as a complex emulsifying agent, the complex emulsifying agent is arranged in a vessel, the temperature is raised to 60-80 DEG C, the complex emulsifying agent is stirred uniformly and the temperature of the complex emulsifying agent is cooled to room temperature, so as to obtain faint yellow complex emulsifying agent; the complex emulsifying agent and auxiliaries are mixed uniformly, the mixture and modified silicone oil are added in a high-shearing silicone oil and are stirred uniformly, and then silicone oil is added dropwise in the mixture, and then the mixture is stirred pH value is regulated, and the obtained white emulsion is proto-filament oiling agent; the process is rational and the operation is simple. The oiling agent is permeated rapidly when being used, the lubricating property is good, fiber bundling property can be improved, the proto-filament oiling agent can be filmed on the monofilament surface, the proto-filament oiling agent is high-temperature resistant, and the agent is not roll-sticking in the drying densifying process, the fiber can be well protected in the whole pre-oxidation process and the low-temperature carbonization period, monofilament adhesion and doubling phenomenon is greatly reduced, surface defect of the fiber is reduced and the fiber performance is improved.

Description

technical field [0001] The invention relates to a production method of oil agent, in particular to a production method of raw silk oil agent used in the carbon fiber production process. Background technique [0002] In the production process of carbon fiber, the production of raw silk is a recognized key link, and the quality and stability of the raw silk have a decisive effect on the performance of the finished carbon fiber. The production process of raw silk includes many processes such as polymerization, single removal and degassing, spinning, oiling, drawing, etc. Among them, the oiling process is a very important part of the raw silk production process. Adhesion or paralleling between monofilaments; local overheating in the pre-oxidation process will lead to local thermal adhesion or thermal paralleling between monofilaments and surface defects; in the low-temperature carbonization process, a large number of by-products are likely to produce inter-filaments Thermal fus...
