Abstract

The utility model relates to automobile nursing series articles, in particular to a sponge grinding block which is of a circular layer structure. A cylindrical shaft made of polyurethane rigid foam is arranged at the center of the sponge grinding block, and the sponge grinding block comprises the cylindrical shaft, a first abrasive paper layer, a semi-rigid foam layer, a second abrasive paper layer, a flexible foam layer and a third abrasive paper layer in sequence from inside to outside. The first abrasive paper layer, the semi-rigid foam layer, the second abrasive paper layer, the flexible foam layer and the third abrasive paper layer are wrapped on the cylindrical shaft. All layers are bonded through glue, the mesh number of the third abrasive paper layer is 80-120, the mesh number of the second abrasive paper layer is 240-300, and the mesh number of the first abrasive paper layer is 300-360. The sponge grinding block is simple in structure, and is of the circular layer structure, so that the same grinding surface can be conveniently ground in a gradual refining mode, the sponge grinding block is convenient to use, practical, and suitable for being popularized and used in a large scale.

Description

Sponge sand lump

Technical field

The utility model relates to car care article series, particularly a kind of sponge sand lump.

Background technology

Sponge sand lump is the polishing articles for use that come into vogue fast in recent years, and its advantage is that matter is soft and deformable space is large, can be used for the polishing to some special-shaped article surfaces.But the sponge sand lump on existing market is one deck sand paper is substantially coated on sponge surface, and function is comparatively single, practicality a little less than.Therefore, developing a kind of convenient and practical sponge sand lump is the problem of current research.

Utility model content

Technical problem to be solved in the utility model is: sponge sand lump a kind of simple in structure, convenient and practical is provided.

The utility model solves the technical scheme that its technical problem adopts: a kind of sponge sand lump, and this sponge sand lump is like structure, the center of sponge sand lump is the cylinder axis that rigid polyurethane is brewed to; Sponge sand lump is followed successively by cylinder axis from inside to outside, be coated on the first sand paper layer on cylinder axis, be coated on semi-rigid foam layer on the first sand paper layer, be coated on the second sand paper layer on semi-rigid foam layer, be coated on the flexible foam layer on the second sand paper layer and be coated on the 3rd sand paper layer on flexible foam layer, bonding by glue between each layer; The order number of described the 3rd sand paper layer is 80-120 order, and the order number of the second sand paper layer is 240-300 order, and the order number of the first sand paper layer is 300-360 order.

Further, the thickness of described flexible foam layer and semi-rigid foam layer is equal, and the bottom of sponge sand lump has the handle being fixedly connected with cylinder axis.

Beneficial effect: compared with prior art; the structure of sponge sand lump of the present utility model is comparatively simple; the setting of the like structure of sponge sand lump; be conducive to same polishing surface to implement meticulous gradually polishing; the setting of froth bed; be conducive to sand paper for the distortion of various compromise faces, convenient and practical, proper scale is promoted the use of.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated;

Fig. 1 is the schematic top plan view of structure of the present utility model;

Fig. 2 is the front schematic view of structure of the present utility model;

In figure, 1. cylinder axis, 2. the first sand paper layer, 3. semi-rigid foam layer, 4. the second sand paper layer, 5. flexible foam layer, 6. the 3rd sand paper layer, 7. handle.

The specific embodiment

A sponge sand lump as shown in drawings, this sponge sand lump is like structure, the center of sponge sand lump is the cylinder axis 1 that rigid polyurethane is brewed to; Sponge sand lump is followed successively by cylinder axis 1 from inside to outside, be coated on the first sand paper layer 2 on cylinder axis 1, be coated on semi-rigid foam layer 3 on the first sand paper layer 2, be coated on the second sand paper layer 4 on semi-rigid foam layer 3, be coated on the flexible foam layer 5 on the second sand paper layer 4 and be coated on the 3rd sand paper layer 6 on flexible foam layer 5, bonding by glue between each layer; The order number of described the 3rd sand paper layer 6 is 80 orders, and the order number of the second sand paper layer 4 is 240 orders, and the order number of the first sand paper layer 2 is 300 orders, and the thickness of flexible foam layer 5 and semi-rigid foam layer 3 is equal, and the bottom of sponge sand lump has the handle 7 being fixedly connected with cylinder axis 1.

The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to claim scope.
