Embodiment 1

[0032] Example 1. Preparation of Compound A

[0033] Add 10Kg aminopropyl silicone oil (viscosity 150cp, ammonia value 0.16mmol / g), 5Kg isopropanol, 220gK to the reactor 2 CO 3 And 230g 3-chloro-2-hydroxypropyltrimethylammonium chloride (content 65%), stir, heat to 85℃~90℃, reflux for 4h, cool to room temperature, filter, evaporate the solvent under reduced pressure, and finally reduce the pressure The temperature is reduced to 133Pa, and the temperature is increased to 120°C to remove small molecules, and a colorless and transparent compound A-1 is obtained.

[0034] The hydrogen nuclear magnetic spectrum of compound A-1 is as figure 1 As shown, the solvent is CDCl 3 . Among them, chemical shift δ=0.099 is the proton peak of silylmethyl group, δ=0.536 is the proton peak of methylene group connected with silicon, δ=1.651 is the proton peak of methylene group connected with silylmethylene, δ=2.719~ 2.737 is the proton peak of the methylene group connected to the nitrogen atom of t...

Abstract

The invention relates to a large-tow carbon fiber oil agent used for wet processing and a preparation method thereof. The large-tow carbon fiber oil agent comprises the following modified oil components in parts by weight: 80 to 90 parts of compound A shown as formula (I), 1 to 3 parts of an antioxidant, 1 to 3 parts of polyether modified silicone and 5 to 15 parts of a non-ionic surface active agent. The large-tow carbon fiber oil agent meets the requirements that the oil agent is free of roller sticking after long-time use, lasting in antistatic property and good in high-temperature heat resistance, the carbon fiber is effectively protected, the requirement for the preparation of wet processing large-tow carbon fiber is met, and the quality of the carbon fiber is improved.

Description

Technical field [0001] The invention relates to an oiling agent, particularly a large tow carbon fiber oiling agent for wet process and a preparation method thereof, and belongs to the technical field of oiling agents. Background technique [0002] In 2016, the global carbon fiber consumption exceeded 76,000 tons. The main application areas are industry, aerospace, sporting goods, automobiles, pressure vessels, etc. It is worth noting that wind turbine blades (mainly used for the "I" support skeleton inside the blades) have surpassed Aerospace has become the largest application field of carbon fiber. With the increasingly tense environmental protection situation, the demand for clean energy is also increasing. Wind power, as a clean energy that has been applied on a large scale, will surely achieve rapid development for a long time in the future, and the amount of carbon fiber as the main support material will also increase significantly. [0003] In the production of carbon fiber...
