NOVELTY - High and low temperature cycle performance of heat-resistant electroplating comprises 25-45 pts. wt. acrylonitrile-butadiene-styrene (ABS) rubber powder, 55-75 pts. wt. styrene acrylonitrile (SAN) resin, 0.1-3 pts. wt. graphene, 0.1-3 pts. wt. compatibilizer, 0.1-1 pts. wt. dispersant, 0.1-1 pts. wt. lubricant and 0.1-1 pts. wt. antioxidant. USE - Used as high and low temperature cycle performance of heat-resistant electroplating. ADVANTAGE - The method improves the plating adhesion, coefficient of linear expansion is reduced and difference between the linear expansion coefficient of the plating layer is reduced. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing high and low temperature cycle performance of heat-resistant electroplating comprising taking the raw into a high speed mixer for mixing for 5-30 minutes, discharging to obtain mixture, (c) taking the obtained mixture into a extruding and pelletizing by double screw extruder at 200-240 degrees C, screw length-diameter ratio is 40-50, rotating the screw at 200-400 revolutions/minute.
