Abstract
An improved brushing nylon wool containing abrasive material used to polish printed circuit board and metallic label boards is made up of granular nylon material, abrasive particles processed by cross-linking agent and solid antiwear lubricant through mixing, heating to melting temp of nylon in extruder and drawing. It features low friction coefficient, high hardness and tension strength and elongating service life by 1.5-2 times.
Description
The present invention relates to a kind of abrasive product and manufacture method thereof.
The grinding material of nylon brushing tool is to be widely used in the instrument that metal surface polishings such as circuit board, label, film mechanical, corrosion resistant plate are handled.The brush silk that constitutes this brushing tool is by nylon and, fusion mixed through the abrasive grain of coupling agent treatment, makes by wire drawing then.The quality of this brushing tool is also unsatisfactory at present, mainly be that hardness, elasticity and the ABRASION RESISTANCE of its grinding material of nylon brush thread is not enough, thereby result of use is not good enough, and service life is shorter.
It is strong to the purpose of this invention is to provide a kind of ABRASION RESISTANCE, hardness, good rigidity, the nylon brush wires containing abrasives of long service life and manufacturing technique thereof.
The technical solution that realizes above-mentioned purpose is: common grinding material of nylon brush thread is to be matrix by nylon, even dispersion and set are through the abrasive grain of coupling agent treatment in the nylon, and the present invention then adds a kind of or several solid lubrication antiwear additives in the nylon that constitutes the brush filament, abrasive mixture.
Suitable composition proportion of composing (percentage by weight) suggestion that the present invention brushes filament is: nylon 62～75%, abrasive material 22～35%, coupling agent 0.2～1%, solid lubrication antiwear additive 1～2%.
The solid lubrication antiwear additive can be chosen from graphite, molybdenum bisuphide, talcum powder, a nitrogenize four boron etc., preferentially recommends molybdenum bisuphide or graphite.
Manufacturing technique of the present invention; comprise the nylon particulate material with evenly mixed through the surface-treated abrasive grain of coupling agent; send into extruder and be heated to the nylon melt temperature; extrude then, wire drawing, cooling; its invention main points are when nylon and abrasive grain are mixed, and it is evenly mixed together to add the solid lubrication antiwear additive simultaneously.
The invention will be further described with an embodiment below.
Optimization formula: nylon selects nylon 1010, and abrasive material selects carborundum, and the solid lubrication antiwear additive selects molybdenum bisuphide, and coupling agent selects the phenylamino triethoxysilane.Its proportioning (percetage by weight) is: nylon 1010 69%, carborundum 29%, molybdenum bisuphide 1.6%, phenylamino triethoxysilane 0.4%.
Concrete manufacturing technology steps and condition:
Take by weighing a certain amount of nylon, abrasive material and solid lubrication antiwear additive raw material by above-mentioned prescription, send into baking oven for heating to 80～120 ℃, constant temperature 1～2 hour respectively; With the coupling agent of certain proportion amount, with 30～50 times diluents (optional acetone) dilution, take out abrasive material from baking oven then and fully mix and stir with it, make coupling agent be bonded to abrasive grain surface diluent and then vapor away; Take out nylon and solid lubrication antiwear additive raw material from baking oven, the abrasive material of crossing with coupling agent treatment evenly mixes; Compound is sent into baking oven for heating to 120～180 ℃, constant temperature 1～2 hour; Compound after the preheating is added extruder be heated to fusion (210～260 ℃), extrude then, wire drawing, cooling, promptly make product of the present invention.
Nylon brush thread of the present invention is made into brushing tool, circuit board is polished test, and under identical experimental condition, compare test with the identical brushing tool of making by common nylon brush wires containing abrasives.Practice shows that under the identical experimental condition of PV value (active force and linear velocity product) maintenance, the coefficient of friction of the more common nylon brush wires containing abrasives of this brush silk reduces by 0.05～0.1, and brush silk hardness and tensile strength obviously improve, and prolong 1.5～2 times service life.
