Abstract

The invention discloses a high impact modified polyvinyl chloride powder. The high impact modified polyvinyl chloride powder comprises, by mass, 50-70% of polyvinyl chloride, 10-15% of polytrimethylene terephthalate, 5-8% of dioctyl phthalate, 6-9% of melamine cyanurate, 3-6% of ABS grafted polymer, 2-4% of methacrylate-acrylate copolymer, 1-3% of polyether modified polysiloxane, 0.5-2% of a benzotriazole ultraviolet ray absorber, 0.5-1.5% of a calcium and zinc composite stabilizer, 0.5-1% of pentaerythritol stearate and 0.1-0.5% of an antioxidant 1010. The high impact modified polyvinyl chloride powder has the advantages of excellent impact resistance and processability, good heat stability, good ageing resistance and good fire retardation performance.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a highly impact-resistant modified polyvinyl chloride powder. Background technique [0002] Polyvinyl chloride (PVC) is one of the five general-purpose resins, and its output is second only to polyethylene (PE). Because PVC has the advantages of high chemical resistance, good electrical insulation performance, stable physical and chemical properties, and low price, At present, it has been widely used in various fields such as industry, agriculture, transportation, construction, communication and medical care. However, pure polyvinyl chloride has problems such as poor thermal stability, low notched impact strength, and low flame retardancy, which will greatly limit its application effect in various fields. Contents of the invention [0003] The object of the present invention is to provide a high-impact modified polyvinyl chloride powder with good flame retardancy, ex...
