The present application relates to wave-absorbing paint technical field, disclose a kind of preparation method and application of color zinc-containing hectorite wave-absorbing material, steps are: lithium smectite, urea and zinc salt are mixed, grinding, form mixture, then added to water, stirring is uniform, 100~160 ℃ hydrothermal reaction 5~10 h, cooling, after suction filtration wash multiple times, obtain zinc-containing lithium smectite;The zinc-containing lithium smectite, ethanol and organic pigment are mixed, grinding, high-temperature baking, obtain color zinc-containing hectorite wave-absorbing material.The material prepared by the present application has the triple effects of wave-absorbing, thickening and coloring, and can improve the application of lithium smectite in paint.

This invention discloses a method for preparing and applying an intercalated montmorillonite / nanocellulose gel packaging film with preservation and monitoring functions. It belongs to the field of packaging materials. This invention uses an ultrasonic-assisted method to insert lithium saponite between montmorillonite layers. Using lithium saponite-intercalated montmorillonite as a template and ascorbic acid as a reducing agent, a lithium saponite-intercalated montmorillonite immobilized nano-copper composite antibacterial agent is prepared. Then, using nanocellulose as a matrix, anthocyanins are added as an indicator and mixed with the immobilized nano-copper antibacterial agent. The resulting intercalated montmorillonite / nanocellulose gel film packaging with preservation and monitoring functions is prepared through a "double drying" technique. When applied to food storage packaging, the lithium saponite-montmorillonite-nanocopper structure exhibits long-lasting antibacterial activity, while the anthocyanins provide an indicator function for monitoring food freshness.
