Problems solved by technology

According to the different conditions and environments of brush filaments, some strong alkaline environments require the selection of brush filaments with strong alkali resistance, but most of the currently commercially available brush filaments are resistant to strong alkaline solutions (such as sodium hydroxide, sodium hypochlorite, potassium hydroxide solution) is poorly tolerated, and its tolerance in high temperature environments is not ideal

Abstract

The invention discloses high-strength alkali-resistant brush wires and a production process thereof, wherein the high-strength alkali-resistant brush wires are composed of the following raw materials in parts by weight: 40-45 parts of polyurethane, 10-20 parts of trimethyl ammonium methyl sulfate, 10-20 parts of a coupling agent, 30-35 parts of fatty alcohol polyoxyethylene ether, 18-20 parts of sodium laurate, 4-5 parts of phosphoric acid, 2-4 parts of monoethanolamine, 6-8 parts of a glass fiber, 3-5 parts of organic alcohol amine, 2-4 parts of azodiisobutyronitrile, 6-8 parts of amino-2-methyl-1-propanol, 12-15 parts of silica, 1-4 parts of polyethylene glycol 4000, 1-3 parts of an accelerator, 10-20 parts of a curing agent, 5-8 parts of an alkali absorption agent, and 2-3 parts of an antioxidant. Compared with the prior art, the alkali absorption agent and the antioxidant are added into abrasive wires, so that the alkali resistance of the abrasive wires and the service life of the abrasive wires in a strong alkali environment are greatly improved. At the same time, the production process is simple, special processing is not required, and the processing cost is low.

Description

technical field [0001] The invention relates to the field of brush filaments, in particular to a high-strength alkali-resistant brush filament and a production process thereof. Background technique [0002] In daily life, brushes are widely used. Using suitable brushes under different conditions, environments and occasions can improve work efficiency and save manpower, financial and material resources. Choosing the right brush is essentially choosing the right brush filament. According to the different conditions and environments of brush filaments, some strong alkaline environments require the selection of brush filaments with strong alkali resistance, but most of the currently commercially available brush filaments are resistant to strong alkaline solutions (such as sodium hydroxide, sodium hypochlorite, potassium hydroxide solution) has poor tolerance, and its tolerance in high temperature environments is not ideal. Contents of the invention [0003] The invention aims...
