Abstract

The invention discloses a polymer energy-saving environment-friendly rare earth composite PVC (Polyvinyl Chloride) resin special material, belonging to the field of PVC resin. The invention aims to solve the problems that raw materials for producing the PVC resin are single, health of production workers is seriously damaged, a great deal of electric energy needs to be consumed, and the capital input is large. The rare earth composite PVC resin special material disclosed by the invention is prepared from the following raw materials in parts by weight: 1000 parts of vinyl chloride monomer (VCM), 25-45 parts of rare earth multifunctional composite stabilizer (REC), 70-90 parts of chlorinated polyethylene (CPE), 40-60 parts of titanium dioxide, 5-20 parts of polyvinyl chloride processing adjuvant, namely acrylic resin (ACR), 130-150 parts of precipitated calcium carbonate (light calcium carbonate), 50-70 parts of nanoscale activated light calcium carbonate, and 0.1-0.5 parts of brightening agent. The material disclosed by the invention is used for producing the PVC resin.

Description

technical field [0001] The invention belongs to the field of PVC resin, and in particular relates to a polymer energy-saving and environment-friendly rare earth composite PVC resin special material. Background technique [0002] At present, the PVC resin raw materials produced in my country are single materials rather than special materials. The processing and configuration process of downstream manufacturers is PVC resin raw materials → various stabilizers → auxiliary materials are mixed. The required production equipment is a mixer → a feeder →The compounding workshop is in the process of compounding. After the compounding is completed, it is added to the extruder to extrude the finished product through the feeder. This kind of production process is particularly cumbersome. During the production compounding process, di-salt, tri-salt or composite lead and cadmium stabilizers are given to workers, which pollutes water, air, is highly toxic, and has radioactive hazards. It wi...
