Abstract

The invention discloses a preparation method of a PVC (polyvinyl chloride) coiled material for wrapping metal. The preparation method includes the operation steps: (1) mixing dysprosium oxide, galliumoxide, aluminum oxide and lanthanum oxide, performing ball-milling treatment, forming obtained powder by compression molding, sintering the powder and then crushing the powder into 80-100 meshes to prepare a reinforcing agent; (2) adding thulium chloride and cerium chloride into water, uniformly mixing and stirring the materials, adding dodecenyl-butanedioic acid dipotassium salt into the materials, uniformly mixing and stirring the materials, performing insulation treatment, pouring an upper aqueous layer, adding the reinforcing agent into mixture, and uniformly mixing and stirring the mixture and the reinforcing agent to prepare a PVC modifying agent; (3) adding PVC resin, the PVC modifying agent, an antioxidant, a plasticizer and inorganic fillers into a high-speed mixer, and performing plastifying, tableting and cutting treatment to prepare a finished product. The PVC coiled material is high in softness and tensile strength and suitable for wrapping the metal and has excellent wear resistance, and the service life of woven goods is greatly prolonged.

Description

technical field [0001] The invention belongs to the technical field of PVC coil preparation, and in particular relates to a preparation method of a PVC coil for wrapping metal. Background technique [0002] Woven products refer to products woven by people or machines. Usually, materials with good toughness such as wicker and reed are used. With the development of polymer material technology and metal weaving technology, PVC-wrapped metal woven products have appeared. After the metal weaving is formed, then wrap the PVC coil on the surface of the metal. The braided product is durable, waterproof, anti-corrosion, and excellent in aging resistance. For example, outdoor hanging chairs, tables, coffee tables, etc. are mostly made by this method. . However, this kind of woven product has poor mechanical properties of the PVC coil, especially low tensile strength and poor wear resistance, resulting in a short service life of the woven product. Contents of the invention [0003]...
