一种环保型绘画专用颜料及其制备工艺
摘要：
本发明公开了一种环保型绘画专用颜料及其制备工艺，包括100-120重量份的碳酸钙、60-80重量份的丙烯酸弹性乳液、1-3重量份的防腐剂、20-40重量份的硅溶胶、10-20重量份的功能助剂、1-3重量份的电气石粉、0.2-1重量份的香料、0.6-1.2重量份的滑石粉和0.2-1重量份的颜料粉。本发明由于在制备工艺中，构成防腐剂的BCM及百菌清是在最后的步骤中加入，不仅能够控制颜料中防腐剂的加入量有效降低制备成本，而且防止其有效成分研磨过程中被破坏，有效提高了防腐剂的利用效率。
摘要（英）：

The invention discloses an environment-friendly special drawing pigment and a preparation process thereof. The environment-friendly special drawing pigment comprises 100-120 parts of calcium carbonate, 60-80 parts of an acrylic elastic emulsion, 1-3 parts of a preservative, 20-40 parts of a silica sol, 10-20 parts of a functional auxiliary agent, 1-3 parts of verdelite powder, 0.2-1 part of spice,0.6-1.2 parts of talcum powder and 0.2-1 part of pigment powder. In a preparation process, BCM and chlorothalonil forming the preservative are added in the final step, so that the preparation cost iseffectively lowered by controlling the adding amount of the preservative in the pigment, and the effective components are prevented from being damaged in the grinding process, so that the utilizationefficiency of the preservative is improved effectively.
