一种可用于3D打印的免喷涂聚丙烯复合材料及其制备方法
摘要：
本发明公开了一种可用于3D打印的免喷涂聚丙烯复合材料及其制备方法，包括按重量百分比计的原料：聚丙烯60-94％，增韧剂5-20％，无机填料0-20％，成核剂0.1-0.5％，金属粉0.2-2％，珠光粉0.2-2％，稳定剂0.2-2％，其它添加剂0-5％。本发明的优点是：1、制造了一种低收缩，不翘曲，光泽好，具有优异的刚性、韧性，具有很强的金属质感和珠光效果的可用于3D打印的免喷涂聚丙烯复合材料，对促进3D打印的材料发展有重要意义；2、最大限度的提高了对无机填料、成核剂、增韧剂、金属粉、珠光粉的剪切和分散，进一步提高了复合材料的性能。
摘要（英）：

The invention discloses a spraying-free polypropylene composite material applicable for 3D print and a preparation method thereof. The composite material is prepared from the following raw materials in percentage by weight: 60-94% of polypropylene, 5-20% of toughing agent, 0-20% of inorganic filler, 0.1-0.5% of nucleating agent, 0.2-2% of metal powder, 0.2-2% of pearl powder, 0.2-2% of stabilizer, and 0-5% of other additive. The composite material and the preparation method thereof have the following advantages: 1, the spraying-free polypropylene composite material applicable for 3D print with low shrinkage, none warping, attractive gloss, excellent rigidity and toughness, very high metal texture and pearl effect is prepared, and the composite material is important for the development of 3D print materials; 2, the shearing and dispersion of inorganic filler, nucleating agent, toughing agent, metal powder and pearl powder are improved furthest, and the performance of the composite material is improved further.
