随着环保要求的提高,涂附磨具行业正加速向环保型胶粘剂转型。反应型聚氨酯热熔胶(PUR)凭借其湿气固化特性带来的柔韧性和环保优势,成为行业重要发展方向之一。本文综述了PUR在涂附磨具中的应用进展,首先概述了PUR在固化环保、柔韧可调、施温低以及适应广等方面的核心优势,同时分析了其面临的技术挑战,主要包括固化与开放时间长、耐温耐湿性有限、流动性不足、成本较高及储存稳定性差等问题。针对这些问题,本文梳理了前人通过原料改性、填料增强、助剂调控等策略显著提升PUR综合性能的相关成果。在此基础上进一步提出,未来本行业可通过产业链协同创新、开发生物基原料以及融合多机制固化技术,推动PUR向更高性能、更环保、功能更复合的方向发展,以满足涂附磨具行业的严苛应用需求。
Abstract:With the increasing demand for environmental protection,the coated abrasive tool industry is accelerating its transformation towards environmentally friendly adhesive.Reactive polyurethane hot melt adhesive(PUR) has become one of the important development directions in the industry due to its flexibility and environmental advantages brought by its moisture curing properties. The application progress of PUR in coated abrasive tool was summarized in this article.Firstly,the core advantages of PUR in curing environmental protection,flexibility and adjustability,low application temperature,and wide adaptability were outlined.At the same time,the technical challenges it faced were analyzed,mainly including long curing and life time,limited temperature and humidity resistance,insufficient fluidity,high costs,and poor storage stability. In response to these issues,the relevant achievements of previous researchers in significantly improving the comprehensive performance of PUR through strategies such as raw material modification,filler reinforcement,and additive regulation were summarized in this article. On this basis,it was further proposed that in the future,through collaborative innovation in the industrial chain,development of bio-based raw materials,and integration of multi mechanism curing technologies,PUR could be developed towards higher performance,environmental friendliness,and more composite functions,in order to meet the stringent application requirements of the coated abrasive tool industry.
