Embodiment 1

[0022] The total weight of raw materials in this example is 1000 kg, of which, 3 kg of quaternary ammonium salt type cationic surfactant, 1 kg of polyoxyethylene-polyoxypropylene polyether, 8 kg of ammonia-modified silicone oil, 8 kg of epoxy-modified silicone oil, 8 kg of polyether modified silicone oil, 20 kg of fluorosilicone oil, 1 kg of polyoxyethylene lauryl silicate, 3 kg of polyoxyethylene lauryl ether, 20 kg of polyoxyethylene hydrogenated castor oil, and the balance is high-purity deionized water.

[0023] 1. Ammonia modified silicone oil

[0024] Ammonia-modified silicone oil considers the following indicators:

[0025] (1) Modified ammonia mass fraction. Calculated based on end-blocked amino-NH2, it is 0.001-0.05. When it is less than 0.001, the hydrophilicity of the oil agent is poor; when it exceeds 0.05, the heat resistance decreases.

[0026] (2) The viscosity after modification is 10-3~5×10-3m2 / s (25°C).

[0027] (3) The modified Si / C ratio should be above...

Abstract

The invention relates to the chemical materials of the new material field, in particular to a high-performance anti-static lubricating finish oil used in the carbon fiber wire-drawing production process. The composition of the raw materials is calculated with the weight percentage. The quaternary ammonium salt type cationic surfactant of 3 to 10, the polyoxyethylene-polyoxy-propylene-polyether of 1 to 3, the ammonia modified silicone oil of 2 to 8, epoxy-modified silicone oil of 2 to 8, polyether modified silicone oil of 2 to 8, the fluoride silicon oil of 10 to 20, lauric acid polyoxyethylene ester of 1 to 3, laurinol polyoxyethylene of 1 to 3, polyoxyethylene hydrogenerated castor oil of 4 to 20, and the rest of high-purity deionized water are stirred in a reaction kettle for 3 to 5 hours with the temperature controlled within the range of 56 to 60 DEG degree, thus the finish oil product can be produced. The invention is applied in the carbon fiber wiredrawing production process, in which the finish oil is in the formation of a membrane on the monofilament surface, not only the adhesion and merging between the monofilaments can be avoided, but also the friction and wear of the fiber surface and the roller during the production process can be prevented. Therefore, the finish oil has excellent smoothness, antistatic property, collection property and self-emulsifying property as well.

Description

technical field [0001] The invention belongs to chemical materials in the field of new materials, in particular to a lubricating and antistatic high-performance oil agent used in the production process of carbon fiber wire drawing. Background technique [0002] Polyacrylonitrile (PAN)-based carbon fiber, as the main reinforcing fiber for advanced composite materials, is an indispensable high-tech material in aerospace and defense industries. Due to the important use of high-performance carbon fiber in the military, foreign countries have imposed a technical blockade and product embargo on my country in recent years. At the same time, the market demand for carbon fiber has increased significantly, carbon fiber is expensive, and the price of related carbon fiber accessories has also soared. In recent years, my country has only increased its investment in the research and development of carbon fiber and its accessories. During the "Eleventh Five-Year Plan" period, my country fo...
