Abstract

The invention discloses a novel coloring masterbatch for cold hot water plastic pipe fittings, and belongs to the technical field of plastic additives. The coloring masterbatch for the cold hot waterplastic pipe fittings is characterized by including the following raw materials in percentages by weight: 25-55% of linear low-density polyethylene, 0-30% of linear polyethylene, 0-50% of carbon black, 0.5-2.5% of an antioxidant, 0.5-2% of a functional auxiliary agent, 0-36% of titanium dioxide, 0-8% of phthalocyanine blue, 0-4% of zinc iron yellow, and 0-0.001% of permanent violet. The coloring masterbatch provided by the invention is used for coloring of PP pipes and PPR pipes, and the prepared pipe fittings have the advantages of a long oxidation induction period and good weather resistance, and can meet the requirements of new standards, thereby promoting the sustainable development of the industry.

Description

technical field [0001] The invention relates to a coloring masterbatch, in particular to a coloring masterbatch for hot and cold water plastic pipe fittings, belonging to the technical field of plastic additives. Background technique [0002] Plastic pipes and fittings for hot and cold water transportation and distribution are widely used in industrial and civil buildings, especially drinking water pipes and fittings. The performance and quality, the guarantee of sanitary conditions, and the length of life directly affect the safety and life of people's lives and property. cost. However, the traditional production process is that pipe and fittings manufacturers make their own ingredients, then mix and extrude them. It not only affects the environment and the health of production workers, but also the product quality and service life cannot be fully guaranteed. Therefore, the new standards promulgated by the state clearly stipulate that, first, the raw materials of pipes an...
