Problems solved by technology

Because rigid PVC has the advantages of good chemical resistance, good electrical insulation, non-flammability, high strength, and low price, it is widely used. PVC pipes are one of its consumption fields, but the disadvantage is poor thermal stability. Susceptible to light, oxygen, heat and cause aging
[0003] At present, the weather resistance, mechanical properties and optical properties of PVC electrical casing are improved by adding color masterbatch. The advantage is low cost, and the disadvantage is that the content of color masterbatch coloring carrier is high, resulting in less pigment content and resulting in weather resistance of its products. reduced, and stress whitening occurs when bent

Abstract

The invention relates to the technical field of color master batches, and discloses a highly-weatherproof and stress-whitening-resistance color master batch for a PVC electrical bushing. The color master batch is prepared from, by weight, 40-80 parts of a carrier, 0.2-3 parts of an antioxidant, 0.1-1.5 parts of an ultraviolet light absorber, 10-50 parts of a plasticizer, 10-40 parts of toner and 0-5 parts of a dispersing agent; the toner is a mixture of titanium dioxide IR-1000 and auxiliary toner. The electrical bushing has excellent weatherproof performance, and can avoid the stress-whitening phenomenon generated when the electrical bushing is bent.

Description

technical field [0001] The invention relates to the technical field of color masterbatches, in particular to a color masterbatch for PVC electrical bushings with high weather resistance and stress whitening resistance. Background technique [0002] Polyvinyl chloride (PVC) is a non-toxic, odorless white powder, which belongs to one of the five general-purpose resins. Because rigid PVC has the advantages of good chemical resistance, good electrical insulation, non-flammability, high strength, and low price, it is widely used. PVC pipes are one of its consumption fields, but the disadvantage is poor thermal stability. It is susceptible to aging due to the effects of light, oxygen and heat. [0003] At present, the weather resistance, mechanical properties and optical properties of PVC electrical casing are improved by adding color masterbatch. The advantage is low cost, and the disadvantage is that the content of color masterbatch coloring carrier is high, resulting in less p...
