Abstract

The invention relates to a glass fiber reinforced polybutylene terephthalate composition with a low floating fiber effect. A PBT resin is used as a base material, PET resin is used as an auxiliary base material, flat glass fiber is used as a reinforcing unit and sodium lignite is used as a floating fiber improving synergist, the low-melting-point PBT resin, the flat glass fiber and the sodium lignite have an excellent low-floating-fiber synergistic effect, and a prepared product is high in strength, high in surface gloss, less in floating fiber and good in mechanical property. Therefore, the use requirements of most appearance workpieces can be met.

Description

Technical field [0001] The invention belongs to the field of polymer composite materials, and particularly relates to a glass fiber reinforced polybutylene terephthalate composition with low floating fiber effect. Background technique [0002] Polybutylene terephthalate (PBT) has excellent long-term heat resistance and milky white background color, and is widely used in electronic appliances, home appliances, cooling fans, lighting and other industries. However, because the PBT resin itself has low mechanical strength, low glass transition temperature, and low notched impact strength, it is often necessary to increase the glass fiber to improve the mechanical properties and toughness at high temperatures. However, the addition of glass fiber causes the glass fiber of PBT injection molded products to leak out, and the surface gloss is poor. It is difficult to be used as the appearance material of the product like PP or PC materials. [0003] Patent CN 106519596A mentions the effect...
