Abstract

The invention relate to the technical field of soft substrate coating grinding devices, in particular to a soft substrate coating grinding device. The soft substrate coating grinding device comprisesa primer layer, material grinding blocks are connected to the upper end of the primer layer at equal distances, a material grinding bulge is connected to an inner cavity of each material grinding block through an adhesion agent in a cemented mode, a TPU soft film substrate is connected to the lower end of the primer layer, and a sponge layer is connected to one end, away from the primer layer, ofthe TPU soft film substrate through a first hot melt glue layer in a cemented mode, and a magic paster is connected to one end, away from the first hot melt glue layer, of the sponge layer through a second hot melt glue layer in a cemented mode. The soft substrate coating grinding device is extremely good in water resisting property, sand dropping and falling-off phenomena do not happen in the life cycle of a product, the TPU coating film of a stereo structure further has an excellent chip removal property and a long service life, the coated product is used for polishing a middle frame of a mobile phone, the obtained product has a long service life and a refined grinding effect, is good in compliance and excellent in abrasion resistance, and a good grinded face can be obtained.

Description

technical field [0001] The invention relates to the technical field of soft substrate coated abrasives, in particular to a soft substrate coated abrasive and its formulation and preparation method. Background technique [0002] The substrates of traditional coated abrasives are mostly cloth base, paper base and PET, which are widely used in many fields, such as mobile phone middle frames, 2.5D or 3D mobile phone casings, high-end musical instruments and furniture, etc. However, each has its own disadvantages. The paper-based substrate has low strength and poor water resistance. It is easily damaged when grinding with liquid. The cloth base is easy to shrink and deform when exposed to water. PET has good water resistance but poor bending performance. When grinding non-planar structures Uniform grinding cannot be achieved. Therefore, it is necessary to prepare a coated abrasive tool for soft substrates, overcome the above-mentioned shortcomings of the abrasive tool, and reali...
