The invention provides a protective layer applied to a vacuum thermal insulation panel and a preparation process of the protective layer. The protective layer comprises calcium powder, cement, sand, fibers, an air entraining agent, a flexible additive and gridding cloth, and comprises the components in percentage by weight: 3%-7% of calcium powder, 30% of cement, 50% of sand, 5% of the fibers, 5%of the air entraining agent and 3%-7% of the flexible additive. The protective layer provided by the invention has flexibility, and the problem that the vacuum thermal insulation panel is easily pierced by sharp hard objects in the transportation and construction process is solved.
本发明提供了一种应用于真空绝热板的防护层及其制备工艺，防护层包括钙粉、水泥、砂子、纤维、引气剂、柔性添加剂、网格布，按重量百分含量计，所述钙粉为3％～7％，水泥为30％，砂子为50％，纤维为5％，引气剂为5％，柔性添加剂为3％～7％。本发明提供的防护层具有柔韧性，解决了真空绝热板在运输和施工过程中容易被尖锐的硬物刺穿的问题。
