The invention relates to a
laser-etched
polypropylene modified material and a preparation method thereof. The
laser-etched
polypropylene modified material is prepared from the following components: 62to 92.8 percent of
polypropylene, 5 to 30 percent of talcum
powder, 1 to 5 percent of
laser-
etching master batch, 0.1 to 0.5 percent of
coupling agent, 0.5 to 1 percent of
lubricant, 0.5 to 1 percentof dispersant and 0.1 to 0.5 percent of
antioxidant. A technology comprises the following steps: firstly, adding all component materials into a mixing
barrel according to the ratio and uniformly mixing; then adding a mixture into a double-screw extruder and mixing, wherein first-section
extrusion temperature and second-section
extrusion temperature of the double-screw extruder are 170 to 180 DEGC,
extrusion temperature of other sections is 190 to 230 DEG C and the total
staying time of reactants in the double-screw extruder is 3 to 8min; finally, after extruding the obtained material, cooling and dicing to obtain the needed laser-etched polypropylene modified material. The material provided by the invention is used on
new energy source automobiles at present and the work of printing, spraying paint and the like on original products is omitted; meanwhile, the environment protection problem caused by links including paint spraying and the like are solved; the material provided by the invention is adaptive to requirements on the development of the times and has a wide application prospect.
