Abstract

The invention discloses a composite material and a preparation method thereof, and belongs to the technical field of resin. AES is introduced into the composite material to serve as a co-toughening agent of ASA, micro-crosslinking of AES and ASA is achieved through the cross-linking agent by means of ethylene propylene rubber in an AES molecular structure, and the heat resistance of the whole system can be improved through the toughening agent obtained after micro-crosslinking on the premise that the toughness is guaranteed. The vicat softening temperature of the composite material can reach 105 DEG C, and the composite material can meet the use requirements of exterior trimming parts of automobile bodies.
