Description
Technical field
The present invention relates to Abrasive Belt Technology field, more particularly to a kind of abrasive band and its manufacture method with super coating.
Background technology
Abrasive band be using binding agent by abrasive material be bonded on the flexible substrates such as paper, cloth made of can be ground and be thrown
A kind of banding instrument of light, it is formed substantially is：Base material, abrasive material and binding agent.
Abrasive band belongs to flexible abrasive product, and sbrasive belt grinding is a kind of Compound Machining work for having and being ground, grind, polishing a variety of effects
Skill is more flexibly lower with safety, precision higher, grinding cost than solid grinding tool emery wheel during polishing.
But when the softer surface of sbrasive belt grinding some quality, such as wooden, lacquer painting easily goes out when softer material
The not smooth situation of existing chip removal, that is, the chip for being ground generation are blocked in abrasive band surface, the grinding performance in abrasive band is declined to a great extent, also shadow
The service life in abrasive band is rung.In order to solve this problem, at present generally by abrasive band surface set chip space or
Abrasive band top layer is coated with one layer of super coating.
Super coating is since cost is higher and pollution is rarely employed at present.Way more at present is set on abrasive band surface
Put chip space, print last layer glue-line generally by substrate surface of the mode of printing in abrasive band, glue-line generally by You Jiao areas and
The adhesive-free area composition pattern of exposure base material, when planting sand, only Jiao Qu can just be planted upper abrasive material, and adhesive-free area is also without abrasive material so as to form
Chip space.Although the abrasive band of this structure has advantage at the anti-blocking aspect of chip removal, due to abrasive band surface abrasive material relatively
It is few, grinding capacity is reduced, and since it is that subregion applies primer and re-glue, it is therefore desirable to the higher printing of service precision
Board carries out applying primer and re-glue operation, and curable adhesive layer also needs to washing later or wind is washed away except floating in chip space
Sand.Therefore, such abrasive band with chip space either in equipment cost or process complexity all with high requirement, from
And the cost in abrasive band is set to increase therewith.
