Special-shaped edge sealing product and preparation method thereof

The invention belongs to the technical field of C08L, and particularly relates to a special-shaped edge sealing product and a preparation method thereof. The invention provides a special-shaped edge sealing product. The special-shaped edge sealing product is prepared from the following raw materials: a polymer base material with the polymerization degree of 500-1500, calcium powder, a functional auxiliary agent and a processing auxiliary agent. The edge sealing product prepared by the method can be used for special-shaped edge sealing, and especially for a small-angle product, a better edge sealing effect can be realized; the edge sealing product provided by the invention is matched with the stearic acid and the PE wax in the system, so that the heavy calcium powder can also dissipate a part of stress, and the edge sealing product is free of fracture during a bending resistance test, and the application value of the special-shaped edge sealing product is improved. 本发明属于C08L技术领域，更具体的涉及一种异型封边产品及其制备方法。本发明的第一方面提出
