Abstract
The utility model relates to the field of grinding tools, in particular to a special emery cloth for grinding the sewing machine needles or cutting knifes. In the special emery cloth for grinding the sewing machine needles or cutting knifes, a grinding layer is affixed to the cloth substrate through a bottom adhesive layer; then a laminating adhesive layer is coated in the clearance of the grinding layer; and the cloth substrate layer is coated with a substrate treating agent layer. The special emery cloth has no substrate treating agent on the backside so as to eliminate slurry scraping on the backside, improve the productivity of the user and reduce the labor costs.
Description
Technical field
The present invention relates to the grinding tool field, especially a kind of special abrasive cloth that grinds needle or cutting knife.
Background technology
Gauze on the market need be made pin and cutting knife that the abrasive band is used for the grinding sewing machine again at the gauze back side at obedient last layer cloth after client's purchase is gone back; We produce emery cloth and scrape the slurry two procedures for the different colours of the stiffness that increases the sand face and outward appearance all will flood with the back side, and all there is the matrix inorganic agent on gauze base material two sides like this.The user buys back, and water that the slurry at the back side is brushed away, and just can be stained with their needed that layer cloth, and not only time-consuming but also effort causes very big trouble to the user; Some producer is also on probation does not scrape slurry, and substrate surface does not have the matrix inorganic agent, because the product width that the user makes is very little, easily collapses the limit when itemize, and sand fallout can not be satisfied user's requirement.So prior art has been wasted a lot of time money when producing.
Summary of the invention
The purpose of this invention is to provide a kind of special abrasive cloth that grinds needle or cutting knife, this kind gauze can solve the shortcoming that existing gauze is wasted time and energy.
The technical scheme that realizes above-mentioned purpose is: a kind of special abrasive cloth that grinds needle or cutting knife, abrasive material is bonded on the cloth base material by primer layer, applies multiple glue-line again in the abrasive material gap, it is characterized in that: be coated with matrix inorganic agent layer on the cloth substrate layer.
Described matrix inorganic agent layer only is coated in the cloth base material front that is bonded with abrasive material.
This kind gauze back side does not have the matrix inorganic agent to save the back side to scrape slurry, improves user's production efficiency, reduces labour cost.
Description of drawings
Fig. 1 is this gauze structural representation.
Among the figure: 1, cloth substrate layer, 2, matrix inorganic agent layer, 3, primer layer, 4, multiple glue-line, 5, abrasive material.
The specific embodiment
Below in conjunction with description of drawings the specific embodiment of the present invention:
Embodiment one: adopt cotton fiber spinning combing, select the rational count of yarn (11 * 16) and density (84 * 48) to select long segment base cloth for use, reduce the reduction that many of joints cause equipment attrition and yield rate, pass through margin to seam, singe, destarch, boiling, washing, technologies such as stretching drying are made the cloth base material, scraping slurry by the front then makes the one side of cloth base material be coated with the matrix inorganic agent, then planting sand makes abrasive material be bonded on that face cloth base material of matrix inorganic agent by the primer of phenolic resins work, again coated with calcium carbonate, titanium dioxide, wollastonite, potassium fluoborate, the hexafluoro aluminic acid such as receives at the multiple glue of mixing manufacture makes more firm being bonded on the cloth base material of abrasive material, the intact back rolling of multiple glue, be cured then and bent gentle the processing, produce the special abrasive cloth of mill needle or cutting knife.
Embodiment two: adopt cotton fiber spinning combing, select the rational count of yarn (9 * 16) and density (84 * 48) to select long segment base cloth for use, reduce the reduction that many of joints cause equipment attrition and yield rate, pass through margin to seam, singe, destarch, boiling, washing, technologies such as stretching drying are made the cloth base material, scraping slurry by the front then makes the one side of cloth base material be coated with the matrix inorganic agent, then planting sand makes abrasive material be bonded on that face cloth base material of matrix inorganic agent by the primer of phenolic resins work, again coated with calcium carbonate, titanium dioxide, wollastonite, potassium fluoborate, the hexafluoro aluminic acid such as receives at the multiple glue of mixing manufacture makes more firm being bonded on the cloth base material of abrasive material, the intact back rolling of multiple glue, be cured then and bent gentle the processing, produce the special abrasive cloth of cloth mill needle or cutting knife.
Embodiment three: adopt cotton fiber spinning combing, select the rational count of yarn (11 * 14) and density (84 * 48) to select long segment base cloth for use, reduce the reduction that many of joints cause equipment attrition and yield rate, pass through margin to seam, singe, destarch, boiling, washing, technologies such as stretching drying are made the cloth base material, scraping slurry by the front then makes the one side of cloth base material be coated with the matrix inorganic agent, then planting sand makes abrasive material be bonded on that face cloth base material of matrix inorganic agent by the primer of phenolic resins work, again coated with calcium carbonate, titanium dioxide, wollastonite, potassium fluoborate, the hexafluoro aluminic acid such as receives at the multiple glue of mixing manufacture makes more firm being bonded on the cloth base material of abrasive material, the intact back rolling of multiple glue, be cured then and bent gentle the processing, produce the special abrasive cloth of mill needle or cutting knife.
