Problems solved by technology

At present, there are still some problems in the quality of the brush wire, mainly because the traditional wire drawing method can only produce straight wire, but not corrugated wire
Intermittent corrugation of straight wires results in uneven curvature, accompanied by indentations, and low production efficiency
Resulting in unsatisfactory product quality in terms of resilience and wear resistance

Embodiment Construction

[0014] Firstly, the natural clay mineral montmorillonite was used as the dispersed phase, and polyamide PA was used as the base material to produce nano-modified nylon plastics by melt intercalation composite technology.

[0015] Montmorillonite (MMT), a nano-inorganic phase material, is a layered silicate. Its structural sheet is nanometer-sized and contains three sublayers. An aluminum-oxygen octahedral sublayer is sandwiched between two silicon-oxygen tetrahedral sublayers. The sublayers are connected by covalent bonds through shared oxygen atoms. Extremely strong. The thickness of the entire structural sheet is about 1 nm, and the length and width are about 100 nm. Since some aluminum atoms in the sublayer of AlO octahedron are replaced by low-valent atoms, the sheet is negatively charged. The excess negative charge depends on the Na dissociated in the interlayer + , Ca 2+ and Mg 2+ and other cations are balanced, so it is easy to carry out ion exchange reaction with ...

Abstract

The present invention is one kind of nylon brush product and its making process, and may be used widely in cleaning, polishing and finishing workpiece surface in different surface shapes. The present invention makes wavy abrasive nylon filament with nano modified nylon as basic material and SiC or Al2O3 of 80-800 mesh grain size as abrasive material, and through soaking in coupling agent, stoving, mixing, smelting, extruding, drawing and pressing to form waves.

Description

Technical field: [0001] The invention relates to a method for manufacturing nylon corrugated abrasive filaments. Background technique: [0002] Since many abrasive wires are equivalent to the same number of flexible files, they can be bent arbitrarily when processing parts, and fit naturally to the contour of the workpiece, and enter grooves, cracks and other places where ordinary tools are difficult to enter, and remove burrs and sharp edges. The blunt is a smooth and uniform arc, which achieves the ideal effect of deburring, edge passivation and surface finishing. At present, there are still some problems in the quality of the brush filaments, mainly because only straight filaments can be prepared according to the traditional wire drawing method, and corrugated filaments cannot be prepared. The intermittent corrugation operation of the straight wire results in uneven curvature and indentation, and the production efficiency is low. Cause product quality to be unsatisfacto...
