Two-side-usable sandpaper with anti-blocking function

Abstract

The invention discloses a kind of two-side-usable sandpaper with the anti-blocking function and relates to the field of abrasive materials. The two-side-usable sandpaper with the anti-blocking function comprises a substrate, a first abrasive material storage box, a second abrasive material storage box, a coarse sand layer and a fine sand layer. The first abrasive material storage box is arranged on the upper surface of the substrate, the coarse sand layer is arranged on the upper surface of the first abrasive material storage box, the second abrasive material storage box is arranged on the lower surface of the substrate, and the fine sand layer is arranged on the lower surface of the second abrasive material storage box. Due to the two-side-usable sandpaper with the anti-blocking function, the trouble caused by the situation that people need to replace sandpaper in the using process can be reduced, waste is reduced, working efficiency is improved, and the hand bruising probability is reduced. Meanwhile, particles such as saw dust and dust generated in the polishing process can be handled in time, the polishing quality can be guaranteed, and the service life of the sandpaper can be prolonged.

Description

Technical field: [0001] The invention relates to the field of abrasive materials, in particular to sandpaper which can be used on both sides and has an anti-blocking function. Background technique: [0002] Sandpaper is used to grind metal, wood, etc. surfaces to a smooth finish. Dry sanding paper is a high-grade product made of synthetic resin as a binder to bond silicon carbide abrasives to latex, and coated with an antistatic coating. It has the advantages of antistatic, good flexibility, and high wear resistance. Available in various grits, suitable for sanding metal surfaces, putties and coatings. Dry sanding paper generally uses special kraft paper and latex paper, uses natural and synthetic resins as binders, and is manufactured through advanced high-static sand-planting technology. This product has high grinding efficiency and is not easy to stick to chips. It is widely used in furniture. , decoration and other industries, especially coarse grinding. [0003] As w...

AI Technical Summary

Problems solved by technology

Before painting, the painter needs to sand with coarse sandpaper first, and then use fine sandpaper to clear the surface, so the sandpaper needs to be replaced on the way, but the coarse sand and fine sand cleaning are a continuous process, and changing the sandpaper will increase trouble, and Sandpaper on one side is also wasteful

In addition, because the existing sandpaper is a thin sheet of paper, it is easy to cause friction between the hand and the wall during the grinding process, which not only affects the work efficiency, but also easily scratches the hand; at the same time, the sandpaper is easy to produce wood chips, Dust and other particles, when these particles accumulate for a long time, the performance of the abrasive layer will be reduced, or even unusable, seriously affecting the service life and grinding quality of the sandpaper
