The specific embodiment
Below in conjunction with accompanying drawing explanation and the specific embodiment, the present invention is described in further detail.
Referring to Fig. 1, Fig. 2, a kind of wear-resisting sand paper with loose structure the present invention relates to, comprise paper base material layer 1 and primer layer 4, the upper surface of paper base material layer 1 is provided with primer layer 4, described paper base material layer 1 lower surface is bonded with one deck grid layer of cloth 2, and the upper surface of primer layer 4 is provided with bulky grain wearing layer 5, and the outer surface of bulky grain high-abrasive material scribbles multiple glue 6, on multiple glue 6, be equipped with the super coating 7 of granule, the surface pressure of paper base material layer 1 is shaped with the micropore 3 that runs through paper base material layer 1 and primer layer 4.
Described bulky grain wearing layer 5 is mixed by titanium dioxide bulky grain, silica bulky grain and calcium carbonate bulky grain.
Described multiple glue 6 is mixed and is made bonding agent by carboxymethyl cellulose, ethyl cellulose, polyvinyl alcohol, and adopts the mixture of toluene, methyl alcohol, ethylene glycol, acetone as solvent.
The super coating 7 of described granule is mixed by diamond dust granule, aluminium dioxide granule and titanium dioxide granule, and the volume of super coating 7 small particles of granule is 6-20 times of the bulky grain volume in bulky grain wearing layer 5.
On described micropore 3, the diameter of micropore is greater than the maximum cross-section area of super coating 7 small particles of granule, and is less than the oarse-grained the maximum cross-section area in bulky grain wearing layer 5.
Referring to Fig. 1, like the prior art, the upper surface of paper base material layer 1 is provided with primer layer 4, different is, paper base material layer 1 lower surface is bonded with one deck grid layer of cloth 2, grid layer of cloth 2 eyelets are larger, and its Main Function is the warping resistance pliability that increases paper base material layer 1, and the performance of passing through simultaneously micropore 3 being produced or not obstruction.The upper surface of primer layer 4 is provided with bulky grain wearing layer 5, and bulky grain wearing layer 5 is mixed by titanium dioxide bulky grain, silica bulky grain and calcium carbonate bulky grain.The particle of bulky grain wearing layer 5 is larger, and extra coarse degree is also larger, but not wear-resisting, in use after polishing to a certain degree, bulky grain wearing layer 5 there will be and comes off and oarse-grained wedge angle partly can be polished, and makes to benefit from the life-span shorter, has indirectly improved polishing cost.
In order to improve the polishing service life of sand paper, particularly improve the polishing effect of meticulous polishing, the present invention scribbles multiple glue 6 at the outer surface of bulky grain high-abrasive material, on multiple glue 6, be equipped with the super coating 7 of granule, glue 6 is mixed and is made bonding agent by carboxymethyl cellulose, ethyl cellulose, polyvinyl alcohol, and adopts the mixture of toluene, methyl alcohol, ethylene glycol, acetone as solvent.Multiple glue 6 is for being adhesively fixed on the bulky grain material on bulky grain wearing layer 5 by the small-particulate materials in the super coating 7 of granule.The super coating 7 of granule is mixed by diamond dust granule, aluminium dioxide granule and titanium dioxide granule, and the volume of super coating 7 small particles of granule is 6-20 times of the bulky grain volume in bulky grain wearing layer 5.The super coating 7 of granule has stronger anti-wear performance; the outer surface that the super coating 7 of granule is adhesively fixed on bulky grain high-abrasive material is conducive to protect to a certain extent bulky grain high-abrasive material; anti-wear performance is improved, and extends the service life of bulky grain wearing layer 5.
In bruting process, dust, the particle that the abrasion resistant particles on sand paper can come off or produce wear debris and the part of polishing produces is easy to stick to the surface of sand paper, and the polishing layer of coated abrasive surface is easy to blocked, even loses grinding capacity.Unresolved the problems referred to above, in the present invention, the surface pressure of paper base material layer 1 is shaped with the micropore 3 that runs through paper base material layer 1 and primer layer 4, on micropore 3, the diameter of micropore is greater than the maximum cross-section area of super coating 7 small particles of granule, and is less than the oarse-grained the maximum cross-section area in bulky grain wearing layer 5.In bruting process; dust, particle that a part of abrasion resistant particles on sand paper can come off or produce wear debris and the generation of polishing part are easy to discharge by micropore on micropore 3; to a certain degree can alleviate the surface dirt of sand paper and the obstruction that little broken particle causes; improved ground effect; and the service life of greatly improving sand paper, significant for the polishing effect that improves meticulous polishing especially.
