Embodiment 1
[0030] This embodiment is a cloth-based fleece-coated abrasive product, the structure of which is as follows: figure 1 Shown, comprise fleece layer 101 and emery cloth layer 109, emery cloth layer 109 comprises cloth-based substrate layer 103 and abrasive material layer 107, the front side of cloth-based substrate layer 103 has fluff layer 105, and the height of fluff layer is less than 100 μ m, the thickness of fluff layer The overall strength of the cloth-based substrate cannot be damaged, the fluff layer 105 is effectively covered by a layer of adhesive layer 104 and forms a smooth composite layer, and the abrasive layer 107 is bonded to the composite layer through the primer layer 106 and the adhesive layer 108. On the layer, the flannelette layer 101 is bonded to the reverse side of the cloth base material layer 103 through the adhesive layer 102 . There is at least one regularly distributed through-hole on the surface of the cloth-based fleece-coated abrasive product, an...
Embodiment 2
[0035] This embodiment is a cloth-based fleece-coated abrasive product, the structure of which is as follows: figure 2 Shown, comprise fleece layer 101 and emery cloth layer 109, emery cloth layer 109 comprises cloth base material layer 103 and abrasive material layer 107, the front and reverse side of cloth base material layer 103 all have fluff layer 105, the height of fluff layer is less than 100 μ m, The fluff layer cannot destroy the overall strength of the cloth-based substrate. The fluff layers 105 on the front and back sides are each effectively covered by a layer of adhesive layer 104 and form a flat front composite layer and reverse composite layer. The abrasive layer 107 passes through the primer layer. The layer 106 and the glue layer 108 are bonded on the front composite layer, and the fleece layer 101 is bonded on the reverse composite layer through the adhesive layer 102 . At least one regularly distributed through-hole is provided on the surface of the cloth-b...
Embodiment 3
[0040] This embodiment is the manufacturing method of cloth-based fleece-coated abrasive products in Examples 1 and 2, which is carried out according to the following procedures: processing of cloth-based base material—manufacturing of emery cloth products—compositing of emery cloth and flannel cloth— Hole making and packaging cut.
[0041] Among them, the manufacture of emery cloth products is carried out according to the following procedures: primer coating - electrostatic sand planting - drying - coating glue - drying - winding - curing - kneading, the processes involved can use the existing process.
[0042] Among them, the treatment of the cloth-based substrate is carried out according to the following procedures:
[0043] (1) Absolute dry weight is less than 180g / m 2 The cloth-based base material is brushed on one or both sides by mechanical means, so that uniform fluff is formed on one or both sides, and the height of the fluff is less than 100 μm;
[0044] (2) Wash ...
