Problems solved by technology

[0002] Polybutylene terephthalate (PBT for short) is a crystalline polymer with excellent comprehensive performance and wide application, but its application is limited due to the shortcomings of PBT's high brittleness, low notched impact strength and insufficient toughness.
Although the use of elastomer toughening can improve the impact toughness of PBT, it greatly reduces its mechanical properties and affects its use.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a modified PBT powder filled with nanoparticles. Background technique [0002] Polybutylene terephthalate (PBT for short) is a crystalline polymer with excellent comprehensive properties and wide application, but its application is limited due to the disadvantages of high brittleness, low notched impact strength and insufficient toughness of PBT. Although the use of elastomer toughening can improve the impact toughness of PBT, it greatly reduces its mechanical properties and affects its use. Contents of the invention [0003] The object of the present invention is to provide a nano particle filled modified PBT powder with good mechanical properties and impact toughness. [0004] The technical solution adopted by the present invention to solve the technical problem is: nano-particle filled modified PBT powder, its components are proportioned by mass percentage: PBT 70...
