Abstract

The invention discloses ultra-flexible coated abrasive cloth, and relates to the technical field of coated abrasive tool products. The ultra-flexible coated abrasive cloth comprises a substrate, an abrasive and a composite adhesive layer; the substrate and the abrasive are coated with the composite adhesive layer, and the abrasive is fixed to the substrate through the composite adhesive layer; thesubstrate comprises a base material and a flexible adhesive layer, and the composite adhesive layer comprises a bottom adhesive layer, a composite adhesive layer body and a coating layer which are distributed from bottom to top in sequence; the flexible adhesive layer comprises one layer of or combination of multiple layers of an upper adhesive layer, a lower adhesive layer and an inner adhesivelayer, the upper adhesive layer and the lower adhesive layer are arranged on the upper surface and the lower surface of the base material correspondingly, and the inner adhesive layer is distributed in the base material; and the base material adopts a cloth base of which the absolute dry weight is 25-180 g / m<2>. The good surface evenness of the coated abrasive cloth can be obtained, the flexible bending radius is 1-3 mm, the ultra-flexible coated abrasive cloth is suitable for grinding of light-load planes and curved surfaces, is resistant to breaking and blocking during grinding, and has thecharacteristics of being good in economical efficiency, light and thin.

Description

technical field [0001] The invention relates to the technical field of coated abrasive products, in particular to a supersoft coated emery cloth and a manufacturing method thereof. Background technique [0002] The existing coated abrasive products have many varieties and are widely used. With the development of science and technology, new grinding parts or grinding materials are produced, corresponding to the demand for grinding tools and grinding materials. At the same time, new materials can also become one of the raw materials for coated abrasive products, and are developed as new varieties of coated abrasive products to achieve new performance or new uses in the grinding process. [0003] In the large-scale grinding operations of traditional woodworking and paint surfaces, there are various forms such as manual grinding, electric or pneumatic tool grinding, etc. In this type of grinding, it is often necessary to grind the workpiece surface such as holes and grooves, a...
