Problems solved by technology

However, there are two major problems with the current silicon-containing oil agent. One is that the amino silicone oil will cross-link and stick to the roller after the production line runs for a long time. The phenomenon of embrittlement and fracture will damage the surface of carbon fiber, especially for high-performance carbon fiber, and even broken wires will occur

Abstract

The invention relates to a compound for improving the heat resistance of an amino-modified silicone oil carbon fiber oil formulation and preparation and application thereof. The compound has the structure shown in a formula (I). The compound is added into the oil formulation to be used by compounding with side chain aminopropyl-modified silicone oil with the kinematic viscosity of 80 cp-300 cp and the amino value of 0.15 mmol/g-0.20 mmol/g, the heat resistance of the oil formulation is greatly improved, and the problems of glue solidifying and roll sticking of the modified silicon oil formulation and modified silicon oil formulation embrittling and fracturing which occur in pre-oxidizing at 350 DEG C are solved.

Description

technical field [0001] The invention relates to a compound for improving the heat resistance of an amino-modified silicone oil carbon fiber oil agent and its preparation and application, belonging to the technical field of oil agents. Background technique [0002] Carbon fiber is a key material supporting strategic emerging industries, and is widely used in national defense, aerospace, wind power, building reinforcement, sporting goods and other fields. [0003] Carbon fiber oil is an essential and important additive in the production process of carbon fiber. It can effectively protect and lubricate carbon fiber in the stages of spinning, pre-oxidation and low-temperature carbonization. It can be said that without high-quality oil, high-quality carbon fiber cannot be produced. . At present, the production technology of carbon fiber oil is mainly mastered by Japanese companies, and domestic technology is relatively backward. [0004] Modified silicone oils have attracted wi...
