Abstract
The utility model relates to the technical field of lapping tools, in particular to sponge sand. The sponge sand comprises a sponge substrate layer, a primer layer, a complex adhesive layer and an abrasive layer. The top face of the primer layer is fixedly connected with the bottom face of the abrasive layer; the middle lower part of the abrasive layer is covered by the complex adhesive layer; a sponge blanching self-skinning layer or a thin layer is arranged between the sponge substrate layer and the primer layer; the bottom face of the sponge blanching self-skinning layer or the thin layer is fixedly connected with the top face of the sponge substrate layer; the bottom face of the primer layer is fixedly connected with the top face of the sponge blanching self-skinning layer or the thin layer. According to the sponge sand provided by the utility model, the phenomena that abrasive waste is caused and the surface abrasive layer of a product is uneven due to the fact that liquid primer glue and abrasives of which the grain diameters are smaller than pore diameters of sponge foam pores in the adhesive layer sink into voids of the sponge foam pores are avoided, so that the surface abrasive layer of the sponge sand is smooth; the use ratio of the abrasives is high; the lapping efficiency can be improved; the processing precision is improved; the surface of a to-be-processed workpiece is more smooth.
Description
Technical field
The utility model relates to milling tool technical field, relates in particular to a kind of sponge sand.
Background technology
Conventionally coated abrasive tool used can be divided into two large classes at present with base material classification:
1, paper base material: it is that coated various hard abrasive materials form on paper substrate, and the advantage of this series products is: low price, being easy to produce, is the most traditional production technology; Shortcoming is: easily tear rotten, pulling force is good not, heat radiation is slow, workpiece to be machined grinding discontinuity, Precision Machining are undesirable;
2, cloth base material: it is that coated various hard abrasive materials form on fabricbase, and key property and the paper product of this series products are close, and advantage is: stretching resistance is large, indeformable, grinding force ratio paper substrate series products strong.
Current product is more and more stricter and derivatives, new class base material series products to the precision machined requirement of grinding, sponge substrate sand paper, be commonly called as sponge sand, it is to take sponge elastomer as base material, and that on sponge elastomer, coated one deck abrasive material forms is flexible, elastic force good, rapid heat dissipation, polishing be without the top grade polishing product of scratch.These advantages are that paper substrate and cloth base product are unexistent.
There is sponge foaming hole in existing sponge sand surface due to sponge substrate in the middle of the process of producing, the little abrasive material of the liquid glue using in manufacturing process and aperture, size ratio sponge foaming hole can infiltrate in the middle of sponge foaming hole, thereby cause the waste of glue and abrasive material, the abrasive material infiltrating in sponge foaming hole is not fully utilized, and shortens the service life of sponge sand.Make abrasive material present rough phenomenon on sponge substrate surface, when the sponge sand that uses this type of explained hereafter is processed product, can cause workpiece to be machined to have the scratch of abrasive material.
Summary of the invention
The utility model provides a kind of sponge sand for overcoming above-mentioned defect, and the abrasive material on this sponge sand surface is smooth smooth, and abrasive material utilization rate is high, can improve grinding efficiency and make the surface flatness, flatness of workpiece to be machined than original further raising.
For achieving the above object, the utility model adopts following technical scheme.
A kind of sponge sand, comprise sponge substrate layer, primer layer, multiple glue-line and abrasive material, the end face of described primer layer is fixedly connected with the bottom surface of described abrasive material, described multiple glue-line covers the middle and lower part of described abrasive material, between described sponge substrate layer and described primer layer, be provided with sponge blanching from skinning cortex or thin layer, sponge blanching is fixedly connected with the end face of described sponge substrate layer from the bottom surface of skinning cortex or thin layer, and the bottom surface of described primer layer is fixedly connected with from the end face of skinning cortex or thin layer with described sponge blanching.
Wherein, the abrasive material in described abrasive material is white fused alumina abrasive material, brown corundum abrasive, silicon carbide abrasive, fused alumina zirconia abrasive material or glass abrasive material.
Wherein, the particle diameter of the abrasive material in described abrasive material is 36-320 order.
Wherein, described thin layer is elastic hot melten gel thin layer, elastic plastic film layer or TPU thin layer.
The beneficial effects of the utility model are: a kind of sponge sand of the present utility model, the upper surface of described sponge substrate layer is provided with sponge blanching from skinning cortex or thin layer, and then establish primer layer, abrasive material, avoided the little abrasive material in aperture in size ratio sponge foaming hole in liquid primer glue and abrasive material to submerge in the hole in sponge foaming hole and caused the rough phenomenon of the waste of abrasive material and the abrasive material of product surface, make the abrasive material on this sponge sand surface smooth smooth, abrasive material utilization rate is high, can improve grinding efficiency and make workpiece to be machined surface more smooth smooth.
