Flame-retardant brush wire

Abstract

The invention discloses a flame-retardant brush wire. The flame-retardant brush wire comprises the following raw materials in parts by weight of 27-34 parts of polybutylene terephthalate fibers, 7-11 parts of epoxy resin, 1-3 parts of zinc hydroxystannate, 2-3 parts of antimony trioxide, 4-6 parts of nano-zinc oxide, 1-2 parts of a plasticizer, 1-2 parts of a cross-linking agent, 8-12 parts of aminopropyltriethoxysilane, 6-8 parts of aminopropyltrimethylamino silane, 1-2 parts of a toughening agent and 5-8 parts of a flame retardant. According to the invention, the polybutylene terephthalate fiber and the epoxy resin are used as main base materials, so that the performance of the brush wire in all aspects is ensured; meanwhile, the zinc hydroxystannate, the antimony trioxide, the nano-zinc oxide, the aminopropyltriethoxysilane and the aminopropyltrimethylamino silane are further added, so that the performance of the brush wire can be further improved; and the flame retardant is added, so that the flame-retardant and combustion suppression properties of the brush wire are further ensured, and the environmental protection and safety of the brush wire in use are improved.

Description

technical field [0001] The invention relates to the field of brush filaments, in particular to a flame-retardant brush filament. Background technique [0002] A brush is a daily tool for cleaning and cleaning. It mainly consists of a combination of brush filaments, brush discs and brush rods. Since the brush filaments are in direct contact with the object to be cleaned, the material selection and performance of the brush filaments are related to the service life of the brush. cleaning efficiency. [0003] Traditional brush filaments are plant fibers or animal hairs, which are not conducive to use because plant fibers or animal hairs are easily damaged, deformed and relatively expensive. Therefore, plastic products are usually used, but plastic products are flammable and produce a large amount of pollutants when burned, which is not conducive to storage, transportation and use. Therefore, in consideration of environmental protection and safety performance, it is necessary to...

Problems solved by technology

[0003] Traditional brush filaments are plant fibers or animal hairs, which are not conducive to use because plant fibers or animal hairs are easily damaged, deformed and relatively high in price.

Therefore, plastic products are usually used, but plastic products are flammable and produce a large amount of pollutants when burned, which is not conducive to storage, transportation and use. Therefore, in consideration of environmental protection and safety performance, it is necessary to design a flame-retardant brush filament to solve the above problems
