The present invention relates to a liquid crystal polymer composition, and a preparation method therefor and the use thereof. The liquid crystal polymer composition comprises the following components in parts by weight: 100 parts of a liquid crystal polymer resin, 10-50 parts of liquid crystal polymer fibers, and 10-50 parts of hollow glass beads, wherein the difference (Tm2-Tm1) between the melting point Tm1 of the liquid crystal polymer resin and the melting point Tm2 of the liquid crystal polymer fibers is greater than or equal to 30ºC; the strength of the liquid crystal polymer fibers is greater than or equal to 5 cN/dtex; and the density of the hollow glass beads is less than or equal to 0.6 g/cm3. The liquid crystal polymer composition has a heat conductivity coefficient of 0.3 W/M/K or less and a tensile strength of greater than 50 MPa, and meets the use requirements of a scenario where high strength and low heat conductivity of a component are required.
