Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention.

The utility model provides a porous elasticity sand table, includes substrate layer 1, the upper surface of substrate layer 1 is provided with flocking layer 2, the lower surface of substrate layer 1 is provided with the layer 3 of polishing, porous elasticity sand table is provided with a plurality of evenly distributed's through-hole 4, through-hole 4 from top to bottom runs through flocking layer 2, substrate layer 1 in proper order and the layer 3 of polishing.

The flocking layer 2 is as the thin throwing face of polishing, and the layer 3 of polishing is as the thick throwing face, and the layer 2 of selecting flocking or the layer 3 of polishing according to the demand of polishing of difference polishes and polishes, realizes two-sided use, the hair side that the magic was pasted can also be regarded as to flocking layer 2, and the cooperation has the polishing chassis of magic subsides thorn face and uses, the fixed and the change of the porous elasticity abrasive disc of being convenient for. The through holes 4 are formed in the porous elastic sand disc, when the porous elastic sand disc is used dry, grinding scraps generated by grinding enter the through holes 4, so that dust is reduced, health risks to operators are reduced, the grinding scraps can be prevented from being accumulated and blocked on the surface of the grinding layer 3, the probability of blocking of the grinding layer 3 is reduced, and the surface of abrasive paper is prevented from losing sharpness and weakening the grinding force; when the abrasive polishing machine is used in a wet mode, the porous elastic sand disc is mounted on the polishing machine after being soaked, abrasive is poured into the porous elastic sand disc, redundant abrasive enters the through hole 4 and is gradually consumed in the polishing process, the frequency of adding the abrasive is reduced, and the working efficiency is improved. The utility model discloses simple structure, practicality are strong, adopt the two-sided polishing layer of polishing of different materials to satisfy different polishing demands, and effectively prevent to block up, polishing effect is good, long service life.

Further, the polishing layer 3 is water sand paper. Specifically, the sand material of the waterproof abrasive paper is silicon carbide. The waterproof abrasive paper has good waterproof performance and is suitable for grinding with water. The waterproof abrasive paper is the waterproof abrasive paper in the prior art, and is used as the application.

Further, the paper base of the waterproof abrasive paper is latex paper. Specifically, the silicon carbide is adhered to the latex paper by a natural resin binder. The latex paper adopts latex paper in the prior art, and the natural resin binder adopts natural resin binder in the prior art, and is used as the application.

The latex paper is good in flexibility and strong in surface adhesive force to sand grains, the durability of the waterproof abrasive paper can be enhanced, and the sand grains adhered to the latex paper are more uniform than other materials and have excellent polishing effect. The silicon carbide is fixed by the natural resin binder, so that the fixing effect is good, sand grains are not easy to fall off, and the service life is long.

Further, substrate layer 1 is the sponge, specifically, substrate layer 1 is the PU sponge. The PU sponge has good elasticity, has good recovery ability when being pressed, has good water absorption performance, and uses the PU sponge as the substrate layer 1 to ensure that the porous elastic sand tray has good rebound resilience and water absorption. The PU sponge is a PU sponge in the prior art, and is used as the application.

Further, the lower surface of the polishing layer 3 is provided with an anti-blocking coating 5. The anti-blocking coating adopts the anti-blocking coating in the prior art, and is used as the application.

The lower surface of the layer 3 of polishing sets up anti-blocking coating 5 and can make the grinding bits fast dispersion who polishes the production not coalesce, avoids the grinding bits to pile up the jam at the layer 3 surface of polishing, further reduces the probability that the layer 3 of polishing blockked up, prevents that the surface of the layer 3 of polishing from losing the sharpness and weakening the grinding power.

Furthermore, a water-absorbing collodion cotton 6 is arranged between the flocking layer 2 and the base material layer 1. Specifically, the absorbent collodion 6 is polyvinyl alcohol collodion. The polyvinyl alcohol collodion cotton is the polyvinyl alcohol collodion cotton in the prior art, and is used as the application.

The absorbent collodion 6 has excellent water absorption performance, and when the porous elastic sand table is used in a wet state, the absorbent collodion 6 is used for storing liquid, releasing the liquid in the polishing process, ensuring that the porous elastic sand table can be polished with water for a long time, reducing the soaking times and improving the working efficiency.

Further, flocking layer 2 passes through natural resin binder and substrate layer 1 fixed connection, is fixed in substrate layer 1 with flocking layer 2 through natural resin binder, and fixed effect is good, and flocking layer 2 is difficult for droing, long service life.
