Description

Grid Sponge sand paper

Technical field

The utility model relates to Sand paper for polishing field, especially a kind of grid Sponge sand paper.

Background technique

Sand paper, also known as rubber；It is a kind of for abradant material, to surfaces such as abrasive metal, timber, so that its is bright and clean Smoothly, deadlocked various abrasive grits form usually on body paper.According to different abrasive materials, sand paper can be divided into diamond dust Paper, artificial diamond's sand paper, glass paper etc. are a variety of.Dry abrasive paper (abrasive paper for wood) is for polishing wood, articles made of bamboo surface.Water-proof abrasive paper (waterproof abrasive paper) is for burnished metal or non-metal workpiece surface in water or in oil.Body paper is all copied with unbleached kraft pulp At papery is tough, wear-resisting folding, and has good water resistance, and the adhesive such as the abrasive materials such as glass sand natural gum are adhered to Body paper is formed through drying.

For example, Chinese patent literature CN203738616U discloses a kind of sand paper, specifically, including: substrate, being coated on Primer layer, the abrasive material being embedded on the primer on the substrate and the re-glue being coated on the primer layer and the abrasive material Layer, the substrate are sponge, and the substrate is that polyethers sponge or EVA type body or polyurethane are fit, the substrate With a thickness of 3-7mm.

Above-mentioned this sand paper in the prior art, although being bonded jointly to abrasive material by using primer layer with complex layer It is fixed, the quality for promoting sand paper, the effect to prolong the service life can be reached；But during actual use, there is also Following problems: first, there are many generation dust during such sand paper polishing, are easy to cause the environment dust from flying of polishing, no Only it is unfavorable for the health of user, and sand paper is easily stifled, will affect grinding effect and efficiency；Second, such sand paper polishing After a period of time, coated abrasive surface easily becomes smooth, and wearability is poor, influences grinding effect；In addition, such Sand paper for polishing connects It after continuous polishing a period of time, generates heat obvious, heat dissipation is slow, the excessively high operation for not only influencing user of sand paper temperature, but also easy pair The surface for being polished substance damages.

Utility model content

In order to overcome the above problem, when the utility model provides a kind of polishing to society dust it is less, it is anti-blocking, heat dissipation Fastly, and also more wear-resisting grid Sponge sand paper.

The technical solution of the utility model is: providing a kind of grid Sponge sand paper, including a substrate and a polishing layer, this dozen The upper surface of the substrate is arranged in mill layer, and the polishing layer is, the polishing compound on the substrate by glue hot pressing Layer is at least grid-shaped on one side be polished that part contacts.

Further include a film layer as the improvement to the utility model, the film layer be folded in the substrate and polishing layer it Between, the film layer is complex as a whole by glue and the substrate and polishing layer.

As the improvement to the utility model, the film layer is TPU film.

As the improvement to the utility model, the thickness range of the film layer is 0.01-0.20mm.

As the improvement to the utility model, the polishing layer is terylene mesh.

As the improvement to the utility model, the substrate is ethylene-vinyl acetate copolymer (EVA) or felt cloth.

As the improvement to the utility model, the glue is PU glue.

It further include abrasive material as the improvement to the utility model, the abrasive material is that the upper of layer of polishing is arranged in Surface.

As the improvement to the utility model, the abrasive material of the abrasive material be fused alumina zirconia, silicon carbide, white fused alumina, Brown Alundum, In ceramics, green silicon carbide, semi-crisp corundum or aluminium oxide.

For the utility model due to including a substrate and a polishing layer, which is arranged in the upper surface of the substrate, described Polishing layer be it is compound on the substrate by glue hot pressing, the polishing layer is at least on one side be polished that part contacts Grid-shaped.In the utility model, the polishing layer be it is grid-shaped, polishing when, the latticed polishing layer energy Dust is enough absorbed, so that dust from flying is reduced, meanwhile, the wearability of latticed polishing layer is good, long service life；In addition, this In utility model, the perfect heat-dissipating of the latticed polishing layer, rapid heat dissipation can speed up heat and distribute, be conducive to polish Operation；Therefore, dust is less, anti-blocking, rapid heat dissipation when the utility model has a polishing, and also more wear-resisting advantage.
