The invention relates to the technical field of polymer materials and composite coatings, and discloses a fiber composite material moisture-curing polymer coating and a preparation method thereof.The fiber composite material moisture-curing polymer coating comprises an adhesive force promoting layer, a primer layer and a net-shaped fiber layer which are sequentially arranged; the thickness ratio of the adhesive force promoting layer to the primer layer to the net-shaped fiber layer is (0.5-1): (1-2): (2-3), and through cooperative construction of the adhesive force promoting layer, the primer layer and the net-shaped fiber layer, a coating system can form a stable and continuous composite structure on the surfaces of different base materials, so that good overall adhesive performance is obtained. The reticular fiber layer is introduced into the wet primer layer in situ, so that fibers are interwoven in the primer layer to form a continuous three-dimensional network structure and are compounded with the primer layer in situ, and the mechanical property and the interface stability of a coating system are effectively enhanced.

This invention proposes an intelligent segmentation method for reticular fiber stained pathological images and its application. Addressing the limitations of existing technologies in identifying reticular fiber structure disruptions to define tumor boundaries and artifacts caused by sliding windows, this invention employs adaptive sliding window segmentation and multi-stage pre-filtering to extract effective image blocks. The input is a dual-stream network, where structural and visual flows are fused through cross-attention based on tissue physical size mapping receptive fields to achieve collaborative verification of visual abnormalities and structural disruptions. Model training utilizes a dynamic boundary-aware loss term with physical scale constraints for joint optimization. Finally, a spatial weight fusion mechanism combined with a graph model incorporating physical priors eliminates breakage artifacts and smooths global boundaries. This invention is primarily used for high-fidelity lesion segmentation of pituitary neuroendocrine tumors.
