The invention provides a semitransparent ABS material and a preparation method thereof. The semitransparent ABS material is prepared by adopting ABS resin and SAN as base materials and adding color master batch, functional additives, metal powder and pearl powder; the compounding of different ABS can effectively decrease the material cost and improve the mechanical performance; by adding SAN, themechanical performance, the light transmittance and the material mobility of the material can be reasonably adjusted; by compounding the metal powder and the pearl powder, the luster effect of the alloy material can meet the appearance application requirement of products; a mobility improver is also used as a scratch-resisting agent, so that the mobility of the material can also be changed, and the material has certain scratch resistance; by adding a lubricating agent, the lubricating property is good, the surface tension is reduced, the friction is reduced, the glossiness is improved, and thescratch resistance of the material can also be improved; and by adding a toughening agent, the mechanical property of the material is reasonably adjusted, so that the prepared transparent material with bright pearly luster, high mobility and high strength can meet the coating-free appearance and other decoration function requirements of a household product.
