Benefits of technology

[0013]Another advantage of the invention is to provides a flocking sanding tool and manufacturing method thereof, wherein the sanding tool comprises a backing layer, an adhesive layer attached to the backing layer for retaining an abrasive layer thereon, wherein the abrasive layer is flocked at the backing layer via a flocking techniques.

[0014]Another advantage of the invention is to provide a flocking sanding tool and manufacturing method thereof, wherein the abrasive particles are evenly distributed on the backing layer by the flocking techniques with even gaps formed between each two abrasive particles. Therefore, the sanding tool of the present invention has a better heat dissipation performance and anti-clogging feature.

[0015]Another advantage of the invention is to provide a flocking sanding tool and manufacturing method thereof, wherein the adhesive layer is a compound layer, comprising a water-based adhesive, a leveling agent and a solidifying agent.

[0016]Another advantage of the invention is to provide a flocking sanding tool and manufacturing method thereof, wherein the adhesive layer comprises a water-based adhesive to withstand the relative high temperature during sanding process, so as to prolong the life span of the sanding tool thereby.

[0017]Another advantage of the invention is to provide a flocking sanding tool and manufacturing method thereof, wherein the material removed from the sanding surface will be washed away from the grinding surface because of the material property of the sanding tool, so as to prevent clogging and enhance a heat dissipation.

[0018]Another advantage of the invention is to provide a flocking sanding tool and manufacturing method thereof, wherein the backing layer is a multi-layer, comprising a web base, backing cloth, and adhesion medium, which is flexible enough to adapt for irregular contours of a workpiece.

Problems solved by technology

However, there existing many shortcomings and disadvantages when applying the conventional sandpaper in practice.

As such, in the process of grinding a metallic surface of a vehicle, the metallic particles removed from the grinded surface would be accumulated between the intervals of the abrasive particles 30A under the sandpaper and cause a clogging gradually thereby.

As it is well known that the clogging would smoothen the abrasive layer, thus the grinding property thereof is weakened substantially.

Further, the friction formed between the sandpaper and the grinding surface is a totally dry friction, where a large amount of heat would generate correspondingly.

The conventional sandpaper has a bad heat dissipation performance because of the clogging and the material of sandpaper.

In particular, the clogging, caused between the grinding surface and the sandpaper, would tighten the contact between the sandpaper and the grinding surface, such that a gap defined therebetween is smaller and the heat-dissipating passage is clogged to some extent.

Moreover, there is no such dry lubricant or the like adding to the conventional sandpaper for improving the friction between the sandpaper and the grinding surface.

Moreover, since the heat generated between the grinding surface and the sandpaper cannot be dissipated in time, the accumulated heat would not only damage the grinding surface but also affect the sandpaper.

Accordingly, when the heat is generated and accumulated on the grinding surface, such as a vehicle surface, the vehicle surface would be burnt, causing a great deal of loss.

As we all known that the vehicle surface is a fine product, even a burned spot would ruin the whole product.

On the other hand, the heat assembled under the sandpaper would melt the bonding layer 2A in some conventional sandpaper products, since the material of the bonding layer 2A cannot withstand the heat generated during machine sanding.

In addition, the material removed from the grinding surface via the sandpaper becomes dust which flies at random at anywhere, which not only damage people's health but also cause a great trouble to clean up.
