Technical Field

[0001] The invention relates to the technical field of straw plastic decorative materials, in particular to a straw extrusion-molded composite decorative adjustable blind. Background Art

[0002] Wheat straw plastic is a new type of green and environmentally friendly composite material made by combining natural plant fibers such as straw, rice husks, and cellulose with polymer resins through a special process. It has similar properties to ordinary thermoplastics and can be directly processed into products using injection molding equipment. Using agricultural renewable resources as the primary raw material, biodegradable plastics are produced using natural polymer materials such as cellulose, starch, wheat straw, and lignin. Through continuous innovative experiments, the development of environmentally friendly cereal fiber material technology has finally been completed.

[0003] The existing Venetian blinds are made of straw extruded composite decorative materials. Although the existing Venetian blinds can meet the needs of users to a certain extent, there are still certain defects during use. For example, during use, the existing Venetian blinds can only adjust the ventilation volume by rotating the blades, but cannot be completely opened, affecting the ventilation effect. For this reason, we provide a straw extruded composite decorative adjustable Venetian blind. Utility Model Content
