Description
Technical Field
The invention belongs to the technical field of materials, and particularly relates to a high-temperature and high-humidity resistant PET heat-shrinkable tubing material and a preparation method thereof.
Background
With the rapid development of the electronic market, more and more capacitors are required. As an environment-friendly material, PET has comprehensive performance superior to that of PVC, and becomes a new material for replacing PVC heat-shrinkable sleeves in the market at present. At present, the technology of the PET heat shrinkable sleeve tends to be mature, the PET heat shrinkable sleeve is environment-friendly in material, good in insulating and coating effects and stable in product, and can meet the application requirements of most customers.
With the increase of the application field of the capacitor, the service environment of the capacitor is more and more diversified, and the requirement on the PET sleeve pipe for coating the capacitor is continuously improved. Especially in the fields of energy conservation and new energy, the development is rapid. Because the internal environment of the automobile is closed, the heat dissipation is not good, the long-term working time is long, and the PET heat-shrinkable tubing which can resist high temperature and high humidity and protect electronic elements is required for the use in the severe environment. Aiming at the high temperature and high humidity resistance of the heat-shrinkable tubing, a double 85 experiment (namely 85 ℃ and 85% RH) is commonly used as a technical index in the industry. The common PET sleeve double 85 experiment in the industry at present generates brittle fracture within 300 hours of 200 plus materials, and the actual application field needs to resist brittle fracture within more than 500 hours, even within 1000H, so that the PET heat-shrinkable sleeve puts forward higher requirements. How to improve the application capability of the PET heat-shrinkable sleeve product in resisting high temperature and high humidity is one of the key technologies for improving the stability and the reliability of the capacitor product.
