The advantages of zinc isoctanoate in aerospace materials and its comparison with other materials

The application of zinc isoctanoate in aerospace materials not only reflects its own superior performance, but also demonstrates its unique advantages over other materials in many aspects. By comparing zinc isoctanoate with other common materials, its irreplaceability in the aerospace field can be more clearly understood.

1. Corrosion resistance

In the aerospace field, corrosion problems of metal materials have always been a key factor restricting equipment life and safety. As an efficient anti-corrosion additive, zinc isoctanoate can significantly improve the corrosion resistance of the material. In contrast, although traditional anti-corrosion materials such as chromate and phosphate can also provide certain protective effects, they have great hidden dangers in environmental protection and health. Due to its carcinogenicity, chromate has been restricted by many countries; phosphate is easily decomposed under high temperature environments, resulting in a decrease in protective effect.

Study shows that zinc isoctanoate has better corrosion resistance than chromate and phosphate in salt spray environments. According to the ASTM B117 standard test, the coating containing zinc isoctanoate still maintains good protective effect after 1000 hours of salt spray test, while the chromate coating showed obvious corrosion under the same conditions. In addition, zinc isoctanoate also has a self-healing function, which can automatically repair when the coating is damaged, further extending the service life of the material.

2. Lubrication performance

The mechanical components in aerospace engines and transmission systems operate under high temperature, high pressure and high load conditions, and the choice of lubricant is crucial. As a high-performance lubricant, zinc isoctanoate can maintain a stable lubrication effect in extreme environments, significantly reducing the coefficient of friction and wear rate. In contrast, although traditional mineral oils and synthetic oils can also provide certain lubricating properties, they are prone to failure under high temperature and high pressure conditions, resulting in increased wear of mechanical components.

Experimental data show that the friction coefficient of lubricants containing zinc isoctanoate at high temperature (250°C) and high pressure (100 MPa) conditions is only 0.09, which is much lower than that of traditional mineral oils. In addition, the wear rate of zinc isoctanoate lubricant is also significantly lower than that of mineral oil, which can effectively extend the service life of mechanical components. It is particularly worth mentioning that zinc isoctanoate lubricants also have good thermal stability and oxidation resistance, and can maintain stable lubricating performance during long-term high-temperature operation, ensuring the normal operation of the engine and other key components.

3. Catalytic properties

In the preparation of aerospace materials, the use of catalysts can accelerate chemical reactions and improve production efficiency. As a highly efficient organic zinc catalyst, zinc isooctanate is widely used in polymer synthesis, coating curing and other fields. Compared with traditional inorganic catalysts, zinc isoctanoate has higher catalytic activity and selectivity, and can achieve rapid curing at lower temperatures and shorten production cycles. In addition, zinc isoctanoate has a lowerToxicity, meets environmental protection requirements, and is suitable for large-scale industrial production.

Study shows that during the curing process, the crosslinking density of epoxy resin containing zinc isoctanoate has increased by 15%, and the glass transition temperature (Tg) has increased by about 10°C. In contrast, although traditional inorganic catalysts such as titanate and aluminate can also promote the curing reaction, they are prone to inactivate at high temperatures, resulting in incomplete curing. In addition, inorganic catalysts are highly toxic and pose a threat to the health of operators, so they are gradually eliminated in the production of aerospace materials.

The experimental results show that the tensile strength and modulus of carbon fiber reinforced composite materials containing zinc isoctanoate have increased by 20% and 15% respectively. In contrast, although traditional silane coupling agents can also improve interfacial binding, they are prone to hydrolysis in high temperature and humid environments, resulting in a degradation of performance. In addition, silane coupling agents have a high volatile nature and have a certain impact on the environment and the health of operators.
