Problems solved by technology

However, the spray-painted outdoor materials prepared by using polyester cloth base material have the disadvantages of poor weather resistance and mechanical properties, complex preparation process, poor environmental protection, and unrecyclable products.
[0003] Chinese patent 200810064601.3 provides a polyvinyl chloride film for inkjet painting, the technical point of which is to add nano-inorganic particles, epoxy soy bean starch, iron white powder, etc. The advantages of clear and bright colors, but it does not have flame retardancy, weather resistance, and environmental protection is not good, it will produce poisonous gas when burned, so it cannot be widely used in inkjet outdoor materials
[0004] Ordinary polyethylene woven materials are extremely easy to burn, and adding ordinary flame retardants and light stabilizers will affect the weather resistance of the material, because flame retardants will cause light stabilizers to fail
Therefore, it is difficult for ordinary polyethylene woven materials to have both flame retardancy and weather resistance, and it is even more difficult to endow them with spray-paintable properties on the basis of both flame retardancy and weather resistance
