用于彩色镀膜镜的镜背保护涂料
摘要：
一种用于彩色镀膜镜的镜背保护涂料，包括底漆和面漆。其中，底漆包括重量百分比25-32的固含量50％丙烯酸改性醇酸树脂、8-15的固含量48％-52％环氧树脂和6-10氨基树脂；面漆包括重量百分比30-40的固含量50％丙烯酸改性醇酸树脂、5-10的固含量48％-52％环氧树脂和4-8氨基树脂。本发明镜背保护涂料未采用具有防腐蚀性能的重金属化合物，对环境友好。本发明涂料可采用大规模幕淋成型工艺，并且可实现快速烘干，在80℃-100℃烘烤条件下4分钟-6分钟即可完全固化，并且具有优良的理化性能，有利于大规模工业化生产。
摘要（英）：

The invention discloses a mirror back protective coating for a colored coated mirror. The mirror back protective coating for the colored coated mirror comprises a primer and a finish, wherein the primer comprises 25 to 32 weight percent of acrylic modified alkyd resin with the solid content of 50 percent, 8 to 15 weight percent of epoxy resin with the solid content of between 48 and 52 percent, and 6 to 10 weight percent of amino resin; and the finish comprises 30 to 40 weight percent of acrylic modified alkyd resin with the solid content of 50 percent, 5 to 10 weight percent of epoxy resin with the solid content of between 48 and 52 percent, and 4 to 8 weight percent of amino resin. Heavy metal compounds with anticorrosion performance are not used in the mirror back protective coating, so the coating is environment-friendly. The coating can be prepared by a large-scale curtain coating molding process, can be quickly oven-dried, can be completely cured after being roasted at the temperature of between 80 and 100 DEG C for 4 to 6 minutes, has excellent physical and chemical properties, and is favorable for large-scale industrialized production.
