Abstract
The invention relates to a coated abrasive tool based on fiber ropes. The purpose of the invention is to solve the technical problem that the base material of any abrasive belt in the prior art does not have a grinding function. The fiber ropes are processed by glue impregnation or coating; primer is coated on the surfaces of the fiber ropes, and abrasive is implanted on the surfaces of the fiber ropes coated with the primer, so that an abrasive layer is formed; and chopped fibers corresponding to the abrasive or the linens are added in the glue for impregnation or coating. Because the abrasive cloth adopts the fiber ropes as base material, the disordered structure of the chopped fibers of the fiber ropes is utilized to enhance the impact resistance of the glue layer, meanwhile, the chopped fibers of the fiber ropes not only can be synchronously consumed, but also have certain polishing and grinding properties, consequently, the performance is enhanced, and the use cost is reduced as well.
Description
Technical field
The present invention relates to a kind of coated abrasive tool based on cordage, belong to grinding tool field.
Background technology
Coated abrasive tool is mainly used in the cleaning of metal part surface, polishing, deburring; The fine grinding of wood furniture; Leather calendering; Good effect has been brought into play in the polishings of clothes cloth fabric glass, pottery etc. in polishing application process.Yet, the emery cloth base material generally using in the market otherwise adopt textile or with blend fabric and the pure chemical & blended fabric of chemical fibre, textile cost strong mechanical performance does not have especially remarkably and not any grinding-polishing function, so the blend fabric of cotton and chemical fibre is owing to being that the combination of materials that two kinds of differences of natural material and synthesized polymer material are larger is difficult to mate very perfectly in processing, so be again especially to require base material to be bound to occur grinding section blackout because glass transition temperature integral body is lower with chemical fibre under the industrial and mineral of abrasive material synchronous consumption, polluting the problems such as grinding workpiece surface cannot overcome, make the whole high cost of manufacturing, for paper, make the tear resistance of product very poor.The base material in any abrasive band of prior art all only has the function of carrying abrasive material, and himself does not have grinding function.
Summary of the invention
The base material that the object of the invention is to solve any abrasive band of prior art does not have the technical problem of grinding function.A kind of coated abrasive tool based on cordage is provided, and this coated abrasive tool adopts cordage as base material, and cost own is low, and significantly promotes its tear resistance after processing, and the properties of product is guaranteed.
The object of the invention is to realize by following technical proposal: a kind of coated abrasive tool based on cordage, comprise cordage, described cordage is flooded by glue or is scraped to soak and processed, and on cordage face, is coated with primer.
In technique scheme, as preferably, can by planting the mode of sand, implant abrasive material being coated with on the cordage face of primer, be formed with abrasive material.In an instantiation, be coated with cordage after primer in sand flow, roll through, until surrounding is planted sand uniformly in cordage, sand amount is controlled at: 3-4g in every gram of cordage.Further, at described abrasive material, add painting face glue.
In technique scheme, as preferably, can in flooding or scraping the glue soaking, add and have abrasive material, adopt containing sand dipping or scrape and soak.In a concrete example, mortar is: the liquid liquid phenolic resin 35% of < mass fraction > modification, abrasive material: 45%, filler: 15%, diluent: 5%, mortar solid content: 75-77%, slurry amount is: 0.7-0.8g on every gram of sisal fiber rope.
In technique scheme, as preferably, can in flooding or scraping the glue soaking, add and the chopped strand of cordage with material.
In the present invention, the fiber of described cordage can be natural fiber, and nature fiber original or that directly obtain on the plant of cultivation, on the animal of artificial feeding, includes but not limited to string, animal origin, mineral fibres.In concrete example of the present invention, described natural fiber is selected from seed fiber, as cotton, kapok etc.; Or leaf fibre, as sisal hemp, abaca etc.; Also or fasciated fiber, as ramie, flax, hemp, jute etc.In another example of the present invention, described natural fiber is selected from hair and silk, such as sheep's wool, goats hair, camel hair, the rabbit hair, yak hair or mulberry silk, tussah silk etc.Natural fiber described in the present invention can also be the recycled fiber of those Mian ﹑ Ma ﹑ Mao ﹑ silks.The fiber of described cordage can also be artificial fiber, includes but not limited to nylon fiber or glass fibre.
In the present invention, described abrasive material refers to sharp keen, hard, in order to the material of the softer material surface of grinding.Described abrasive material can be natural abrasive, includes but not limited to natural emery, Naxas emery, garnet and natural diamond etc.; Also can be artificial abrasive material, include but not limited to brown corundum abrasive, white fused alumina abrasive material, single alundum abrasive material, black silicon carbide grain, green silicon carbide abrasive material, cubic silicon carbide abrasive material, cerium silicon carbide abrasive material, boron carbide, diamond and cubic boron nitride etc., and the recovery sand of vitrified abrasive, resin wheel etc. etc.
In technique scheme, the described end, primer, face glue or glue are one or more in following material: urea aldehyde and modified resin thereof, phenolic aldehyde and modified resin thereof, epoxy and modified resin thereof, acrylic acid and modified resin, inorganic binder, consumption is 20～50% of raw material gross mass.In a concrete example, primer is < mass fraction >: the liquid liquid phenolic resin 65% of modification, and filler: 35%, glue solid content: 75-77%, glue amount is: 0.7-0.8g on every gram of sisal fiber rope.
From technical characterictic of the present invention, can find out, the invention has the advantages that: utilize cordage as base material, by glue, flood or scrape and soak processing, make its inside contain abrasive material or chopped strand, strengthen every mechanical property, and by upper primer and plant sand, the tear resistance of whole product is significantly improved, and utilize the low cost of cordage that the whole cost of manufacturing is significantly reduced.This coated abrasive tool adopts cordage as base material, and cost own is low, and will significantly promote the grinding performance of its fiber itself after processing, and the properties of product is greatly improved; In particular as the processing of face wheel and sized flap wheel raising property product valency ratio greatly.Cordage generally has two kinds of forms: the one, and by dipping, contain the glue of sand and solidify each position that relief sand bonds to fiber cloth and then utilize this material to carry out grinding; The 2nd, after containing the glue of sand and be coated with primer by dipping, plant sand final curing, thereby utilize together with the sand be implanted in inside surface and fiber and participate in grinding, cordage base material does not wash destarch with water can directly process to reach requirement by glue, thereby cost-saving and reduce environmental pollution widely.
