Abstract: Using basic copper carbonate and basic zinc carbonate as raw materials, nanocomposite preservatives（MCZ） were prepared after wet grinding. By blending acrylate emulsion, silicon-containing acrylate emulsion and MCZ, modified MCZ and silicon-containing modified MCZ were obtained, and the rubber wood was treated with modified MCZ by dipping method, and the effect of acrylate emulsion and silicon-containing acrylate emulsion on anti-loss properties of nanocomposite MCZ were studied. The results showed that when the mass ratio of MCZ and acrylate emulsion was 1∶1, the modified MCZ had the best bleed resistance, which was 11.18% higher than that of MCZ and 5.86% lower in corrosion resistance（white rot bacteria）, but still met the requirements of strong corrosion resistance grade requirements. The nanocomposite preservative modified by silicon-containing acrylate emulsion had lower loss and higher corrosion resistance than acrylate emulsion modified composite preservative. When the silicon content was 4%, the loss rate of the preservative was 2.4%, and the weight loss rate of treated wood was 4.43%. The nanocomposite preservative modified by silicon-containing acrylate emulsion had the characteristics of strong loss resistance, good corrosion resistance, safety and environmental protection. This research has a positive role in promoting the development and utilization of environmentally friendly wood preservatives.
