| Abstract:As a high-value-added specialty paper， the excellent optical properties， printability， and durability of decorative base paper rely on titanium dioxide fillers. The typical dosage of titanium dioxide fillers ranges from 15% to 45%， and its high price relative to wood pulp fibers significantly increases production costs. Therefore， to achieve green and sustainable development in the specialty paper industry， the development of efficient and economical titanium dioxide reduction and replacement technologies is of great significance for reducing production costs， alleviating resource pressure， and promoting green transformation. This article systematically reviewed recent research progress in this field from the perspectives of wet-end chemistry regulation， composite filler preparation， and novel filler applications， providing theoretical references and technical insights for cost reduction， efficiency improvement， and high-performance development of decorative base paper. |
