Wear-resistant fireproof abrasive brushing wire and preparation method thereof

Abstract

The invention discloses a wear-resistant fireproof abrasive brushing wire which comprises, by mass, 25-35 parts of nylon 6, 15-19 parts of nylon 1010, 6-13 parts of nylon MXD, 2-3 parts of glass fiber, 1.5-3.8 parts of carbon fiber, 8-19 parts of polyethylene resin, 3-5 parts of ceramic particle, 5-8 parts of diamond, 1-2.5 parts of antiwear agent, 2-3.5 parts of moisturizing agent, 0.8-1.5 partsof antiager, 1-2 parts of halogen-free flame retardant, 0.1-0.3 part of catalyst, 1.5-3 parts of heat resistant agent and 0.1-0.5 part of alcohol. The preparation method includes: respectively puttingthe halogen-free flame retardant, the catalyst, the nylon 6, the nylon 1010 and the nylon MXD into a reaction system solution to obtain flame-retardant nylon; putting the flame-retardant nylon into ahigh-speed mixer, sequentially adding the antiwear agent, the moisturizing agent and the antiager, mixing, adding the ceramic particle and diamond into a mixture, continuously stirring, adding alcohol for condensation reaction, extruding raw materials obtained after being mixed through a screw extruder, enabling the raw materials to enter a metering pump, and performing stretch wire-drawing through a die head at the front end of the metering pump to obtain the brushing wire.

Description

technical field [0001] The invention relates to the technical field of abrasive brush filament processing, in particular to a wear-resistant and fireproof abrasive brush filament and a preparation method thereof. Background technique [0002] Nylon, also known as polyamide, is the most widely used thermoplastic engineering plastic at home and abroad. It has excellent properties such as toughness, wear resistance, impact resistance, fatigue resistance, corrosion resistance, and oil resistance. For decades, its usage has been increasing and its application range has become wider and wider. The total demand has always ranked first among the five engineering plastics. . Nylon is used as raw material to produce various brush filaments, and its demand is also relatively large.

AI Technical Summary

Problems solved by technology

[0003] Industrial abrasive brushes are widely used in surface treatment, grinding and polishing, finishing, and deburring. The fineness of workpiece surface treatment mainly depends on the quality of abrasive brushes. The existing brushes are generally made of PP, nylon, sisal, For pig bristle, horse bristle and other materials, the existing brush filaments have the defects of low tensile strength of abrasive brush filaments, short service life, and rough friction by the surface of the working material, which makes the brush filaments shed.

Nylon 610 brush wire has good wear resistance, high temperature resistance, acid and alkali resistance, etc., but the elasticity of 610 is not very good, and it is easy to deform and difficult to recover after long-term work. Therefore, 610 is suitable for rough parts in industrial dust removal and cleaning. For example, the dust removal of mine docks, the sweeping brush of sanitation vehicles, etc.; the elasticity of PBT is better than 610, but the wear resistance is not as good as 610, and the performance of PBT is softer. It is most suitable for cleaning and decontamination of fine parts, such as car surface cleaning, air conditioning Air duct cleaning and so on; while 1010 has the best elasticity and the highest cost, but its wear resistance is not as good as 610, its appearance is relatively good, and its impact resistance and aging resistance are also very good. It is most suitable for industrial equipment and doors and windows and other dust-proof parts
