This invention relates to the field of computer-aided engineering technology and discloses a method for generating unstructured meshes based on graph convolutional networks (GCNs) and high-order size fields. It aims to solve the problems of striping artifacts easily generated when generating size fields from STL background meshes, and the excessive computational burden caused by global encryption. The method first generates an initial size field based on an STL mesh; then, it constructs a GCN model to extract features and classifies edges to identify striped edges; next, it employs a "detection-selective order-upgrading" strategy, inserting high-order nodes only on striped mesh edges to construct a high-order background mesh; finally, it uses a hybrid interpolation strategy, employing linear interpolation for non-striped mesh edges and cubic spline interpolation for high-order edges to calculate size values. This invention efficiently eliminates artifacts without changing the global topology, enabling the generation of high-quality unstructured meshes.

This invention discloses a method for preparing and applying a high-bird-drop-resistant clear coat for automobiles, belonging to the field of automotive coating technology. This invention constructs a special ternary crosslinking network of "acrylic resin-amino resin-blocked isocyanate" and introduces a functional resin containing urethane bonds (-NH-CO-O-) as an acid-resistant modifying component to prepare a high-performance single-component solvent-based clear coat. The method first constructs a basic crosslinking system through the pre-dispersion of multiple resins, then uses leveling agents, drying agents, and other additives for synergistic compounding and regulation, finally obtaining the finished product. The clear coat of this invention utilizes the high chemical inertness of urethane bonds to significantly improve the paint film's resistance to acidic substances in bird droppings, achieving a bird dropping resistance rating of Rbd2 or higher, while maintaining the ease of application of a single-component system.
