Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a high-toughness polyvinyl chloride sheet. Background technique [0002] Polyvinyl chloride (PVC) plastic is polymerized from vinyl chloride monomer. It is one of the commonly used thermoplastics. It is widely used in all aspects of production and life. It can be used to make agricultural films, raincoats, tablecloths, handbags, and artificial leather. , pearl products, storage boxes, pipes and other products. [0003] Pure polyvinyl chloride resin is a hard thermoplastic substance, its decomposition temperature is very close to the plasticizing temperature, and its mechanical strength is poor. Therefore, polyvinyl chloride resin cannot be used to mold products, and plasticizers, stabilizers, fillers, etc. must be added to improve performance to make polyvinyl chloride plastics, and then processed into various products. However, the existing conventional p...
