The invention relates to an automobile ABS sheet and a preparation method thereofA way of vehicle ABS sheet and making, only include the overall surface plate, the middle layer and bottom, making the whole process of the following: according to the net weight ABS97 ~ 98, toughening agent 5 ~ 8, 4 ~ 8, high temperature resistant modified materials antioxidant 0.6 ~ 1.2, 0.4 ~ 0.8, light stabilizer for halogen free flame retardant 0.6 ~ 0.8, processing aid 1.0 ~ 1.5, pigment, 1 ~ 3 nanotechnology 0.2 ~ 1 inorganic antibacterial agent and mineral oil in advance to prepare the whole surface of 0.4 ~ 0.5, the lowest; Prepare intermediate raw materials in advance to purchase ABS materials; Put the two raw materials into the two high mixing machine respectively and mix them for 2-5min before discharging. The cylinder temperature of the control twin-screw extruder is 210 ~ 230℃, and the screw speed ratio of the extruder is 200 ~ 400rpm. The melted raw materials are squeezed into the molds (1) respectively. The die shell (1) has a forming concave die assembled by the lower die (2), the middle plate (3) and the lower die (4). The discharge from the twin screw extruder (6) is fed into the lower die (2) and the lower die (4). After the discharge from the second twin screw extruder (5) is fed into the middle plate (3), the forming is carried out and the shape is fixed. |
