Abstract
The invention relates to a polyvinyl chloride powdery plastic dipping composition, and belongs to the technical field of processing and application of high-molecular materials. The polyvinyl chloride powdery plastic dipping composition is characterized by comprising the following components (in parts by weight): 100 parts of polyvinyl chloride, 2-15 parts of polyvinyl chloride paste resin, 35-65 parts of plasticizing agent, 1-7 parts of stabilizing agent, 1-6 parts of epoxidized soybean oil, 2-10 parts of lubricating agent and 0-10 parts of filler, wherein polyvinyl chloride is suspension method polyvinyl chloride resin, the polymerization degree is 500-800, and the grain diameter is 50-200 micrometers; the polymerization degree of the polyvinyl chloride paste resin is 1000, and the grain diameter is 5-20 micrometers. Compared with the prior art, the polyvinyl chloride powdery plastic dipping composition disclosed by the invention achieves shorter melting and plasticizing time and better leveling property of a plastic dipping product by requiring the polymerization degree of polyvinyl chloride resin powder and the granular size of the composition.
Description
technical field [0001] The invention discloses a polyvinyl chloride powder dipping composition, which belongs to the technical field of polymer material processing and application. Background technique [0002] Plastic dipping is a processing method in which the surface-treated metal products are dipped into resin powder or resin paste in a preheated state, and the resin on the surface of the metal layer is heated and plasticized to obtain a plastic coating on the surface. Plastic-dipped products are suitable for various metal guardrails, frames, tools, the outer coating of metal cages for aquatic product breeding, and the coating of wire mesh, etc., and have broad markets in industry, agriculture and daily necessities. [0003] At present, domestic plastic dipping mainly uses PVC paste resin, which is soaked in a plasticizer for a long time and mixed to form a slurry or paste shape, then dipped in plastic, and then heated, plasticized and shaped to make PVC products. In or...
