Description
Technical field
The invention belongs to high-strength accurate grinding and polishing field, and in particular to a kind of Wear-resistant Sharper with thin film base and its
Manufacture method.
Background technology
In fields such as traditional construction and decoration, Furniture manufacturing, machine-building, need that the surface of many articles is carried out to beat
Mill.The material commonly used in bruting process is sand paper, and existing sand paper has convenient for production, and cost is relatively low, the features such as versatility is good
It is commonly employed.But, existing sand paper service life is general shorter, and the polishing layer on surface does not also grind completely
Damage comes off the grinding capacity that just had been out, its basic reason remove sand paper itself tear resistance it is poor outside, prior original
Because be in bruting process, the abrasion resistant particles on sand paper can come off or produce wear debris and polishing part generation dust,
Grain is easy to stick to the surface of sand paper, and the polishing layer of coated abrasive surface is blocked, and loses grinding capacity.
The Chinese patent application of the A of Publication No. CN 103567894 discloses a kind of wear-resisting sand paper with loose structure,
Including paper base material layer and primer layer, the upper surface of paper base material layer is provided with paper base material layer lower surface described in primer layer and is bonded with one
Layer scrim layer, the upper surface of primer layer is provided with bulky grain wearing layer, and the outer surface of bulky grain high-abrasive material scribbles re-glue, multiple
The super coating of little particle is equipped with glue, the surface rolling of paper base material layer has the micropore through paper base material layer and primer layer.This is resistance to
The abrasive resistance of dry sanding paper is improved, and the polishing layer of coated abrasive surface is not easy to be blocked, and service life is extended.
With the development of the technologies such as liquid crystal panel manufacture, optic communication, automobile making, to associated grinding and polishing field
Requirement also more and more higher.Traditional grinding-material is using base materials such as cloth, paper, it is impossible to reaches compliance and is provided simultaneously with high intensity,
And high-strength PET base material (polyethylene terephthalate) is adopted, this problem not only can be overcome, and can reach more
Uniform thickness, it is possible to achieve more accurate, stable, lasting grinding effect, so as to reach the target of precise finiss polishing.Existing
Under generationization manufacturing condition, the precise finiss of fiber stub end face, the grinding and polishing of mirror roller, automobile crane, camshaft etc. are beaten
The grinding and polishing of mill, the micro Process of micro machine motor and phone housing, logo etc., all be unable to do without thin film base grinding-material.
The Chinese patent application of the A of Publication No. CN 101259595 discloses a kind of section grinding side of multi-core optical connector
