Degradable paper-plastic material as well as preparation method and application thereof

The invention provides a degradable paper-plastic material as well as a preparation method and application thereof, and belongs to the technical field of environment-friendly materials. The degradable paper-plastic material is prepared from the following raw materials in percentage by weight: 90 to 95.5 percent of plant fiber pulp board, 1.5 to 3 percent of sizing agent, 0 to 5 percent of oil-proof agent, 1 to 2 percent of dry strength agent and 1 to 2 percent of wet strength agent. The degradable paper-plastic material is prepared from the preparation raw materials through the processes of repulping, size mixing, forming, hot-pressing sizing, shaping and trimming and assembling in sequence. The preparation method is simple and low in cost, and the obtained material is smooth and attractive in surface, high in strength and good in waterproof and moisture-proof performance and is a completely degradable material. Meanwhile, the material is good in plasticity and can be used for manufacturing various packaging
