Reinforced material as well as preparation method and application thereof

The invention discloses a reinforced HIPS material as well as a preparation method and application thereof. The reinforced HIPS material is prepared from the following components in parts by weight: 45-80 parts of HIPS resin, 10-20 parts of GPPS resin, 10-20 parts of SBS resin, 10-15 parts of reinforced glass fibers, 1-5 parts of a compatilizer, 0.4 part of an antioxidant and 0.5-1 part of a lubricant. The preparation method comprises the following steps: melting desired parts by weight of the HIPS resin, the GPPS resin, a flexibilizer, the antioxidant and the lubricant in a twin-screw extruder, laterally feeding the reinforced glass fibers, and conducting extruding to obtain the reinforced HIPS material. The reinforced HIPS material prepared by the invention has good toughness and rigidity; the glossiness of the material can reach 96 (60 degrees) through an RHCM injection molding technology; cost is low; and the reinforced HIPS material can replace ABS + GF and PCABS + GF to form a front frame workpiece of a
