Special abrasive belt for polishing metal fittings and preparation process of abrasive belt

The invention provides a special abrasive belt for polishing metal fittings and a preparation process of the abrasive belt, and relates to the technical field of abrasive belt machining. The abrasive belt according to the invention is sequentially provided with an abrasive material layer, a compound adhesive layer, a bottom adhesive layer, a base cloth layer and a back scraping layer from top to bottom. By adjusting the composition of the compound adhesive layer, the bottom adhesive layer and the back scraping layer, the abrasive belt can effectively adhere to an abrasive material, so that the service life of the abrasive belt is prolonged. According to the abrasive belt, deviation can be avoided, the effect of polishing the metal fittings is excellent, and scratches cannot be generated on the surfaces of the metal fittings. 本发明提供了一种小五金打磨专用砂带及其制备工艺，涉及砂带加工技术领域。本发明砂带从上到下依次设置有磨料层、复胶层、底胶层、基布层、背刮层。通过调整复合胶层以及底胶层、背刮层的组成，使得砂带能够有效粘附磨料，提高了砂带的使用寿命。本发明的砂带能够避免发生偏移，对小五金进行打磨的效果优异，不会对其表面产生划痕。
