Abstract

The invention discloses high-glow wire flame-retardant reinforced PBT plastic for printing white characters through laser and a preparation method of the PBT plastic. The PBT plastic comprises the following components: 21-47% of PBT, 4-10% of PET, 5-12% of melamine cyanurate, 10-13% of brominated epoxy resin, 0.5-3% of sodium antimonate, 2-5% of triphenyl phosphate, 1-3% of ethylene-methyl acrylate copolymer grafted with glycidyl methacrylate, 1-3% of subgroup metal element oxide, 0.3-1% of antioxidant, 0.3-1% of lubricant, and 22-30% glass fiber. Meanwhile, the invention also discloses a preparation method of the high-glow wire flame-retardant reinforced PBT plastic for printing white characters through laser. The PBT plastic disclosed by the invention has the flame retardant property andthe mechanical property at the same time, not only can meet the requirement of a glow wire on a non-ignition temperature of 850 DEG C, but also can meet the requirement for the mechanical property, and the product has the characteristic of laser marking and is suitable for the application requirement of laser printing of white characters.

Description

Technical field [0001] The invention belongs to the technical field of polymer materials, and particularly relates to a high-glow wire flame-retardant reinforced laser-printed white PBT plastic and a preparation method thereof. Background technique [0002] Polybutylene terephthalate, English name polybutylene terephthalate (abbreviated as PBT), is a thermoplastic polyester, which was developed by Celanese in the United States in the early 1970s. PBT has very good heat resistance, weather resistance, chemical resistance, and has the advantages of excellent electrical performance, low water absorption, and good surface. It is widely used in electronic and electrical, automotive, machinery, household appliances and other industries, especially Electronic and electrical industry. [0003] Generally, the electrical and electronic industries have mostly flame-retardant requirements for materials, and generally require the glow-wire non-flammable temperature to reach 750°C throughout th...
