Technical Field

[0002] Outdoor high activity curing (HAA) polyester resin is a special polymer material with the characteristics of fast curing, strong weather resistance, excellent mechanical properties, etc. It is widely used in coatings, boats, automobiles and construction. In order to meet the needs of different application conditions, the formula and preparation process of HAA polyester resin need to be adjusted and optimized.
[0003] The key steps in producing HAA polyester resin include monomer ratio, prepolymerization reaction, curing reaction, etc. Each step has an important impact on the performance of the final product, so strict quality control measures must be implemented. The monomer ratio is the starting point of the entire production process and determines the basic skeleton and performance indicators of the polyester resin. The correct monomer ratio is not only related to the basic properties of the polymer such as molecular weight, molecular weight distribution, and cross-linking density, but also directly affects the curing speed, weather resistance and mechanical properties of the product. The choice of curing reaction temperature and time not only affects the curing speed, but also affects the cross-linking density and the formation of the network structure, which in turn affects the mechanical properties and weather resistance of the polyester resin.
[0004] Traditional quality management methods mainly rely on laboratory testing and manual monitoring. Product samples are taken regularly, and quality is evaluated through physical and chemical tests and performance tests, and process parameters are adjusted accordingly. However, this approach has some obvious defects: manual monitoring and data analysis are inefficient, it is difficult to detect potential quality risk factors in a timely manner, it relies heavily on manual experience and judgment, and lacks scientific process control and quality prediction models.
